<blockquote>
<p> 一、查看邮件是否已被阅读</p>
</blockquote>
<p>当你在发送邮件时，你或许很想知道该邮件是否被对方已阅读。这里有段非常有趣的代码片段能够显示对方IP地址记录阅读的实际日期和时间。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">error_reporting(0);</span><br><span class="line">Header("Content-Type: image/jpeg");</span><br><span class="line">//Get IP</span><br><span class="line">if (!empty($_SERVER['HTTP_CLIENT_IP']))</span><br><span class="line">{</span><br><span class="line"> $ip=$_SERVER['HTTP_CLIENT_IP'];</span><br><span class="line">}</span><br><span class="line">elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))</span><br><span class="line">{</span><br><span class="line"> $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];</span><br><span class="line">}</span><br><span class="line">else</span><br><span class="line">{</span><br><span class="line"> $ip=$_SERVER['REMOTE_ADDR'];</span><br><span class="line">}</span><br><span class="line">//Time</span><br><span class="line">$actual_time = time();</span><br><span class="line">$actual_day = date('Y.m.d', $actual_time);</span><br><span class="line">$actual_day_chart = date('d/m/y', $actual_time);</span><br><span class="line">$actual_hour = date('H:i:s', $actual_time);</span><br><span class="line">//GET Browser</span><br><span class="line">$browser = $_SERVER['HTTP_USER_AGENT'];</span><br><span class="line">//LOG</span><br><span class="line">$myFile = "log.txt";</span><br><span class="line">$fh = fopen($myFile, 'a+');</span><br><span class="line">$stringData = $actual_day . ' ' . $actual_hour . ' ' . $ip . ' ' . $browser . ' ' . "\r\n";</span><br><span class="line">fwrite($fh, $stringData);</span><br><span class="line">fclose($fh);</span><br><span class="line">//Generate Image (Es. dimesion is 1x1)</span><br><span class="line">$newimage = ImageCreate(1,1);</span><br><span class="line">$grigio = ImageColorAllocate($newimage,255,255,255);</span><br><span class="line">ImageJPEG($newimage);</span><br><span class="line">ImageDestroy($newimage);</span><br><span class="line">?></span><br></pre></td></tr></table></figure>
<blockquote>
<p> 二、从网页中提取关键字</p>
</blockquote>
<p>一段伟大的代码片段能够轻松的从网页中提取关键字。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">$meta = get_meta_tags('http://www.emoticode.net/');</span><br><span class="line">$keywords = $meta['keywords'];</span><br><span class="line">// Split keywords</span><br><span class="line">$keywords = explode(',', $keywords );</span><br><span class="line">// Trim them</span><br><span class="line">$keywords = array_map( 'trim', $keywords );</span><br><span class="line">// Remove empty values</span><br><span class="line">$keywords = array_filter( $keywords );</span><br><span class="line">print_r( $keywords );</span><br></pre></td></tr></table></figure>
<blockquote>
<p> 三、查找页面上的所有链接</p>
</blockquote>
<p>使用DOM，你可以轻松从任何页面上抓取链接，代码示例如下：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">$html = file_get_contents('http://www.example.com');</span><br><span class="line">$dom = new DOMDocument();</span><br><span class="line">@$dom->loadHTML($html);</span><br><span class="line">// grab all the on the page</span><br><span class="line">$xpath = new DOMXPath($dom);</span><br><span class="line">$hrefs = $xpath->evaluate("/html/body//a");</span><br><span class="line"></span><br><span class="line">for ($i = 0; $i < $hrefs->length; $i++) {</span><br><span class="line"> $href = $hrefs->item($i);</span><br><span class="line"> $url = $href->getAttribute('href');</span><br><span class="line"> echo $url.'<br />';</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<blockquote>
<p> 四、自动转换URL，跳转至超链接</p>
</blockquote>
<p>在WordPress中，如果你想自动转换URL，跳转至超链接页面，你可以利用内置的函数make_clickable()执行此操作。如果你想基于WordPress之外操作该程序，那么你可以参考wp-includes/formatting.php源代码。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">function _make_url_clickable_cb($matches) {</span><br><span class="line"> $ret = '';</span><br><span class="line"> $url = $matches[2];</span><br><span class="line"></span><br><span class="line"> if ( empty($url) )</span><br><span class="line"> return $matches[0];</span><br><span class="line"> // removed trailing [.,;:] from URL</span><br><span class="line"> if ( in_array(substr($url, -1), array('.', ',', ';', ':')) === true ) {</span><br><span class="line"> $ret = substr($url, -1);</span><br><span class="line"> $url = substr($url, 0, strlen($url)-1);</span><br><span class="line"> }</span><br><span class="line"> return $matches[1] . "<a href=\"$url\" rel=\"nofollow\">$url</a>" . $ret;</span><br><span class="line">}</span><br><span class="line">function _make_web_ftp_clickable_cb($matches) {</span><br><span class="line"> $ret = '';</span><br><span class="line"> $dest = $matches[2];</span><br><span class="line"> $dest = 'http://' . $dest;</span><br><span class="line"> if ( empty($dest) )</span><br><span class="line"> return $matches[0];</span><br><span class="line"> // removed trailing [,;:] from URL</span><br><span class="line"> if ( in_array(substr($dest, -1), array('.', ',', ';', ':')) === true ) {</span><br><span class="line"> $ret = substr($dest, -1);</span><br><span class="line"> $dest = substr($dest, 0, strlen($dest)-1);</span><br><span class="line"> }</span><br><span class="line"> return $matches[1] .

<blockquote>
<p> 五、创建数据URL</p>
</blockquote>
<p>数据URL可以直接嵌入到HTML/CSS/JS中，以节省大量的 HTTP请求。 下面的这段代码可利用$file轻松创建数据URL</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">function data_uri($file, $mime) {</span><br><span class="line"> $contents=file_get_contents($file);</span><br><span class="line"> $base64=base64_encode($contents);</span><br><span class="line"> echo "data:$mime;base64,$base64";</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<blockquote>
<p> 六、从服务器上下载&保存一个远程图片</p>
</blockquote>
<p>当你在搭建网站时，从远程服务器下载某张图片并且将其保存在自己的服务器上，这一操作会经常用到。代码如下：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">$image = file_get_contents('http://www.url.com/image.jpg');</span><br><span class="line">file_put_contents('/images/image.jpg', $image); //Where to save the image</span><br></pre></td></tr></table></figure>
<blockquote>
<p> 七、移除Remove Microsoft Word HTML Tag</p>
</blockquote>
<p>当你使用Microsoft Word会创建许多Tag，比如font，span，style，class等。这些标签对于Word本身而言是非常有用的，但是当你从Word粘贴至网页时，你会发现很多无用的Tag。因此，下面的这段代码可帮助你删除所有无用的Word HTML Tag。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">function cleanHTML($html) {</span><br><span class="line">/// <summary></span><br><span class="line">/// Removes all FONT and SPAN tags, and all Class and Style attributes.</span><br><span class="line">/// Designed to get rid of non-standard Microsoft Word HTML tags.</span><br><span class="line">/// </summary></span><br><span class="line">// start by completely removing all unwanted tags</span><br><span class="line"></span><br><span class="line">$html = ereg_replace("<(/)?(font|span|del|ins)[^>]*>","",$html);</span><br><span class="line"></span><br><span class="line">// then run another pass over the html (twice), removing unwanted attributes</span><br><span class="line"></span><br><span class="line">$html = ereg_replace("<([^>]*)(class|lang|style|size|face)=("[^"]*"|'[^']*'|[^>]+)([^>]*)>","<\1>",$html);</span><br><span class="line">$html = ereg_replace("<([^>]*)(class|lang|style|size|face)=("[^"]*"|'[^']*'|[^>]+)([^>]*)>","<\1>",$html);</span><br><span class="line">return $html</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<blockquote>
<p> 八、检测浏览器语言</p>
</blockquote>
<p>如果你的网站上有多种语言，那么可以使用这段代码作为默认的语言来检测浏览器语言。该段代码将返回浏览器客户端使用的初始语言。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line">function get_client_language($availableLanguages, $default='en'){</span><br><span class="line"> if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {</span><br><span class="line"> $langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']);</span><br><span class="line"></span><br><span class="line"> foreach ($langs as $value){</span><br><span class="line"> $choice=substr($value,0,2);</span><br><span class="line"> if(in_array($choice, $availableLanguages)){</span><br><span class="line"> return $choice;</span><br><span class="line"> }</span><br><span class="line"> }</span><br><span class="line"> } </span><br><span class="line"> return $default;</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<blockquote>
<p> 九、显示Facebook 粉丝数量 </p>
</blockquote>
<p>如果你的网站或者博客上有内链的Facebook页面，你或许想知道拥有多少粉丝。这段代码将帮助你查看Facebook粉丝数，记住，别忘了在你的页面ID第二行添加该段代码</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><?php</span><br><span class="line"> $page_id = "YOUR PAGE-ID";</span><br><span class="line"> $xml = @simplexml_load_file("http://api.facebook.com/restserver.php?method=facebook.fql.query&query=SELECT%20fan_count%20FROM%20page%20WHERE%20page_id=".$page_id."") or die ("a lot");</span><br><span class="line"> $fans = $xml->page->fan_count;</span><br><span class="line"> echo $fans;</span><br><span class="line">?></span><br></pre></td></tr></table></figure>

<url>/2018/04/08/CentOS-7-Git%E6%9C%8D%E5%8A%A1%E5%99%A8%E6%90%AD%E5%BB%BA%E5%8F%8A%E9%85%8D%E7%BD%AE%E5%85%AC%E9%92%A5/</url>
<content><![CDATA[<a id="more"></a>
<p><strong>一、Git服务器搭建</strong></p>
<p>a. 安装Git</p>
<blockquote>
<p>yum install -y git</p>
</blockquote>
<p>b. 添加新用户、为用户设置密码</p>
<blockquote>
<p>adduser git<br>passwd git</p>
</blockquote>
<p>c. 创建空的Git仓库</p>
<blockquote>
<p>cd /home/git<br>git init --bare test.git<br>chown -R git:git ../git</p>
</blockquote>
<p>d. 在服务器端打开RSA认证</p>
<blockquote>
<p>cd /home/git<br>mkdir .ssh<br>cd .ssh<br>touch authorized_keys </p>
</blockquote>
<p>e. 命令行创建SSH key</p>
<blockquote>
<p>ssh-keygen -t rsa -C “<a href="mailto:x@qq.com">x@qq.com</a>“</p>
</blockquote>
<p>Linux 家目录/.ssh/:id_rsa、id_rsa.pub。<br>windows C:\Users\Administrator.ssh\</p>
<p>f.把步骤5生成的公钥导入服务器</p>
<blockquote>
<p>cat id_rsa.pub >> /home/git/.ssh/authorized_keys</p>
</blockquote>
<p>简单操作：windows 打开 Git-Gui->Help->Show SSH Key 直接复制key到Linux authorized_keys文件中 </p>
<p><strong>二、配置钩子</strong></p>
<p>a. 设置clone帐号的SSH key<br>我用的lnmp的环境 用户为 www</p>
<blockquote>
<p>sudo -u www ssh-keygen -t rsa -C “<a href="mailto:b@qq.com">b@qq.com</a>“<br>cat id_rsa.pub >> /home/git/.ssh/authorized_keys</p>
</blockquote>
<p>b. 设置Git用户使用www用户clone<br>设置了 /etc/sudoers 添加：</p>
<blockquote>
<p>git ALL=(ALL) NOPASSWD: ALL</p>
</blockquote>
<p>进入网站目录拉取<br>su git<br>sudo -u www git clone ssh://[email protected]/home/git/test.git </p>
<p>c. 配置钩子[主要]</p>
<blockquote>
<p>cd /home/git/test.git/hooks/<br>vim post-receive</p>
</blockquote>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">#!/bin/bash</span><br><span class="line">export LANG=zh_CN.UTF-8</span><br><span class="line">cd /home/wwwroot/www/test/</span><br><span class="line">unset GIT_DIR </span><br><span class="line">sudo -u www git pull origin master</span><br></pre></td></tr></table></figure>
<blockquote>
<p>chown git:git post-receive<br>chmod +x post-receive</p>
</blockquote>
<p>在本地clone拉取远程git仓库</p>
<blockquote>
<p>git clone ssh://[email protected]/home/git/test.git</p>
</blockquote>
<p><strong>git 回滚到任意版本操作</strong></p>
<blockquote>
<p>git reset –hard xxx[版本号]<br>git push -f origin master</p>
</blockquote>
<p><strong>git known_hosts</strong></p>
<blockquote>
<p>sudo -u www ssh-keygen -R 127.0.0.1<br>sudo -u www git pull origin master</p>
</blockquote>

<title>CentOS 7 安装 Nginx 1.11.x</title>
<url>/2018/03/21/CentOS-7-%E5%AE%89%E8%A3%85-Nginx-1-11-x/</url>
<content><![CDATA[<p><strong>Centos下安装Nginx</strong> </p>
<a id="more"></a>
<p>一、准备工作 安装必备工具</p>
<blockquote>
<p>yum install -y gcc gcc-c++ autoconf automake<br>yum install -y zlib zlib-devel openssl openssl-devel pcre-devel</p>
</blockquote>
<p>不安装这些依赖库，后面编译的时候会报错，当然你的系统已经有这些包可以跳过。<br>pcre：用来作地址重写的功能。<br>zlib：nginx 的gzip模块,传输数据打包，省流量（但消耗资源）。<br>openssl：提供ssl加密协议。</p>
<p>二、添加nginx用户</p>
<blockquote>
<p>/usr/sbin/groupadd -f www<br>/usr/sbin/useradd -g www www</p>
</blockquote>
<p>三、nginx文件准备及编译</p>
<blockquote>
<p>wget <a href="http://nginx.org/download/nginx-1.11.4.tar.gz">http://nginx.org/download/nginx-1.11.4.tar.gz</a><br>tar -zxvf nginx-1.11.4.tar.gz<br>cd nginx-1.11.4/<br>./configure –user=www –group=www<br>make && make install</p>
</blockquote>
<p>四、开始firewall端口服务</p>
<blockquote>
<p>firewall-cmd –permanent –zone=public –add-service=http<br>firewall-cmd –reload</p>
</blockquote>
<p>常用命令</p>
<blockquote>
<p>/usr/local/nginx/sbin/nginx -s reload<br>/usr/local/nginx/sbin/nginx -s stop<br>/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf</p>

</blockquote>
<p>添加</p>
<blockquote>
<p>[/]<br>test = rw</p>
</blockquote>
<p>d.配置文件</p>
<blockquote>
<p>vim svnserve.conf</p>
</blockquote>
<p>修改配置[启用]</p>
<blockquote>
<p>anon-access = none<br>auth-access = write # 授权用户可写<br>password-db = passwd # 使用哪个文件作为账号文件<br>authz-db = authz # 使用哪个文件作为权限文件<br>realm = /home/svn/repos # 认证空间名，版本库所在目录</p>
</blockquote>
<p>e.启动svn</p>
<blockquote>
<p>svnserve -d -r /home/svn # 启动svn版本库<br>svnserve -d -r /home/svn/repos # 启动svn版本库<br>killall svnserve # 停止SVN命令</p>
</blockquote>
<p><strong>三.钩子文件</strong></p>
<p>1.钩子配置</p>
<blockquote>
<p>cd ../hooks/<br>cp post-commit.tmpl post-commit<br>chmod +x post-commit<br>vim post-commit</p>

<blockquote>
<p>WEBPATH=”/home/wwwroot/test/“ # 网站目录<br>export.UTF-8<br>svn update $WEBPATH –username[test] username –password password[123456] –no-auth-cache</p>
</blockquote>
<p>3.拉取文件[在有副本的目录下]</p>
<blockquote>
<p>svn co svn://127.0.0.1/ ./<br>若拉取文件报错,请在有副本目录下拉取一下,然后把隐藏的文件夹 .svn文件放到需要拉取的目录下 就Ok了.</p>
</blockquote>
<p>4.拉取单个文件</p>
<blockquote>
<p>svn up laravel.log</p>
</blockquote>

<title>CentOS 7 安装MySQL5.7</title>
<url>/2018/03/21/CentOS-7-%E5%AE%89%E8%A3%85MySQL5-7/</url>
<content><![CDATA[<p><strong>Centos下安装MySQL</strong> </p>
<a id="more"></a>
<p>官方mysql.com 支持我们使用yum的方式安装mysql 5.7最新版。所以大家根本无需手工编译安装（除非你需要）。CentOS7的yum源中默认好像是没有mysql的。为了解决这个问题，我们要先下载mysql的repo源。<br>一、下载mysql的repo源</p>
<blockquote>
<p>wget <a href="http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm">http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm</a></p>
</blockquote>
<p>二、 安装mysql57-community-release-el7-9.noarch.rpm包</p>
<blockquote>
<p>rpm -ivh mysql57-community-release-el7-9.noarch.rpm</p>
</blockquote>
<p>三、 安装mysql （下载需要一段时间)</p>
<blockquote>
<p>yum install mysql-community-server</p>
</blockquote>
<p>四、启动mysql</p>
<blockquote>
<p>systemctl start mysqld<br>systemctl enable mysqld.service</p>
</blockquote>
<p>五、第一次启动后，mysql5.7 会生成一个随机root密码 （MySQL 5.7.6以上）</p>
<blockquote>
<p>grep ‘temporary passwor’ /var/log/mysqld.log</p>
</blockquote>
<p>修改root密码</p>
<blockquote>
<p>ALTER USER USER() IDENTIFIED BY ‘123456’;</p>
</blockquote>
<p>外网访问</p>
<blockquote>
<p>mysql -u root -p # 首次登录会修改密码<br>GRANT ALL PRIVILEGES ON <em>.</em> TO ‘root’@’%’ IDENTIFIED BY ‘your_root_password’ WITH GRANT OPTION;</p>
</blockquote>
<p>删除mysql</p>
<blockquote>
<p>rpm -qa|grep mysql；<br>yum remove packages</p>
</blockquote>
<p>端口查看</p>
<blockquote>
<p>ps -aux | grep mysql<br>netstat -apn | grep 3306<br>netstat -apn</p>
</blockquote>

<content><![CDATA[<a id="more"></a>
<p><strong>一、安装docker</strong></p>
<p>Go to：<a href="https://download.docker.com/linux/centos/7/x86_64/stable/Packages/" target="_blank">[ .rpm安装路径 ]</a> <a href="https://docs.docker.com/engine/installation/linux/docker-ce/centos/#install-using-the-repository" target="_blank">[ 官方参考 ]</a><br><img src="/assets/blogImg/laradock/1.png" alt="ico原来的样子"></p>
<p>打开路径地址，本文默认安装选择最新版，<br><img src="/assets/blogImg/laradock/2.png" alt="ico原来的样子"><br>下载rpm安装包</p>
<blockquote>
<p> wget <a href="https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.09.0.ce-1.el7.centos.x86_64.rpm">https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.09.0.ce-1.el7.centos.x86_64.rpm</a></p>

</blockquote>
<p>启动docker –hello[docker run hello-world]</p>
<blockquote>
<p> systemctl start docker<br>systemctl enable docker 开机启动</p>
</blockquote>
<p><strong>二、CentOS 7配置中国镜像</strong></p>
<p><a href="https://yq.aliyun.com/articles/29941" target="_blank">[ 参考配置原文 ]</a> docker –registry-mirror=<a href="https://registry.docker-cn.com/">https://registry.docker-cn.com</a> daemon [提示找不到registry]</p>
<ul>
<li>CentOS的配置方式略微复杂，需要先将默认的配置文件复制出来</li>
<li>/lib/systemd/system/docker.service -> /etc/systemd/system/docker.service</li>
<li>然后再将加速器地址添加到配置文件的启动命令</li>
<li>重启Docker就可以了。</li>
</ul>
<blockquote>
<ul>
<li>sudo cp -n /lib/systemd/system/docker.service /etc/systemd/system/docker.service</li>
<li>sudo sed -i “s|ExecStart=/usr/bin/docker daemon|ExecStart=/usr/bin/docker daemon –registry-mirror=<a href="https://registry.docker-cn.com|g"/">https://registry.docker-cn.com|g"</a> /etc/systemd/system/docker.service</li>
<li>sudo sed -i “s|ExecStart=/usr/bin/dockerd|ExecStart=/usr/bin/dockerd –registry-mirror=<a href="https://registry.docker-cn.com|g"/">https://registry.docker-cn.com|g"</a> /etc/systemd/system/docker.service</li>
<li>sudo systemctl daemon-reload</li>
<li>sudo systemctl restart docker </li>
</ul>
</blockquote>
<p>docker 安装完成！！！</p>
<p><strong>三、拉取 Laradock</strong></p>
<ul>
<li>目录路径[/home/]</li>

<title>Etcd一文</title>
<url>/2021/11/04/Etcd%E4%B8%80%E6%96%87/</url>
<content><![CDATA[<p><img src="/assets/blogImg/etcd.png" alt="Etcd"></p>
<a id="more"></a>
<p><strong>一、概述</strong></p>
<blockquote>
<p>背景：近期k8s应用中etcd的功能存在一些困惑，对其进行来单独的学习，能更深入理解k8s中的的一些特性。</p>
</blockquote>
<ul>
<li>简单：安装配置简单，而且提供了HTTP API进行交互，使用也很简单</li>
<li>安全：支持SSL证书验证</li>
<li>快速：根据官方提供的benchmark数据，单实例支持每秒2k+读操作</li>
<li>可靠：采用raft算法，实现分布式系统数据的可用性和一致性</li>
</ul>
<p><strong>二、应用场景</strong></p>
<ul>
<li>服务注册与发现</li>
<li>消息发布与订阅</li>
<li>负载均衡</li>
<li>分部署通知与协调</li>
<li>分布式锁</li>
<li>分布式队列</li>
<li>集群与监控与Leader选举</li>
</ul>
<p><strong>三、安装部署</strong></p>
<p>推荐使用yum安装方式</p>
<blockquote>
<p>hostnamectl set-hostname etcd-1<br>wget <a href="http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm">http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm</a><br>rpm -ivh epel-release-latest-7.noarch.rpm</p>
<h1 id="yum-仓库中的etcd版本为3-3-11，如果需要最新版本的etcd可以进行二进制安装"><a href="#yum-仓库中的etcd版本为3-3-11，如果需要最新版本的etcd可以进行二进制安装" class="headerlink" title="yum 仓库中的etcd版本为3.3.11，如果需要最新版本的etcd可以进行二进制安装"></a>yum 仓库中的etcd版本为3.3.11，如果需要最新版本的etcd可以进行二进制安装</h1><p>yum -y install etcd<br>systemctl enable etcd</p>
</blockquote>
<p><strong>四、简单使用</strong></p>
<p>1、增加 set</p>
<blockquote>
<p>$ etcdctl set /testdir/testkey “Hello world”<br>Hello world</p>
</blockquote>
<p>2、删除 rm</p>
<blockquote>
<p>$ etcdctl rm /testdir/testkey<br>PrevNode.Value: Hello</p>
</blockquote>
<p>3、更新 update</p>
<blockquote>
<p>etcdctl update /testdir/testkey “Hello”<br>Hello</p>
</blockquote>
<p>4、查询 get</p>
<blockquote>
<p>etcdctl get /testdir/testkey<br>Hello world</p>
</blockquote>
<p><strong>五、总结</strong></p>
<ul>
<li><p>etcd 默认只保存 1000 个历史事件，所以不适合有大量更新操作的场景，这样会导致数据的丢失。 etcd 典型的应用场景是配置管理和服务发现，这些场景都是读多写少的。</p>
</li>
<li><p>相比于 zookeeper，etcd 使用起来要简单很多。不过要实现真正的服务发现功能，etcd 还需要和其他工具（比如 registrator、confd 等）一起使用来实现服务的自动注册和更新。</p>
</li>
<li><p>目前 etcd 还没有图形化的工具。 </p>
</li>
</ul>

<title>Centos下安装PHP7</title>
<url>/2018/03/21/Centos%E4%B8%8B%E5%AE%89%E8%A3%85PHP7/</url>
<content><![CDATA[<a id="more"></a>
<p>一、安装yum仓库</p>
<blockquote>
<p>yum install epel-release<br>rpm -Uvh <a href="https://mirror.webtatic.com/yum/el7/webtatic-release.rpm">https://mirror.webtatic.com/yum/el7/webtatic-release.rpm</a></p>
</blockquote>
<p>二、安装php7</p>
<blockquote>
<p>yum install php70w<br>php -v</p>
</blockquote>
<p>三、安装php扩展</p>
<blockquote>
<p>yum search php70<br>yum install php70w-xml php70w-soap php70w-xmlrpc<br>yum install php70w-mbstring php70w-json php70w-gd php70w-mcrypt<br>yum install php70w-fpm php70w-mysql php70w-pdo php70w-opcache</p>
</blockquote>
<p>nginx 配置 php</p>
<p>1、启动fpm</p>
<blockquote>
<p>systemctl start php-fpm<br>systemctl enable php-fpm # 开机启动</p>
</blockquote>
<p>2、配置nginx</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">location ~ \.php$ {</span><br><span class="line"> root html; </span><br><span class="line"> fastcgi_pass 127.0.0.1:9000; # 也可以用 socket 进行连接</span><br><span class="line"> fastcgi_index index.php;</span><br><span class="line"> fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;</span><br><span class="line"> include fastcgi_params;</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>3、重启nginx</p>
<blockquote>
<p>systemctl restart nginx</p>
</blockquote>
<p>##php 错误日志##<br>nginx是一个web服务器，因此nginx的access日志只有对访问页面的记录，不会有php 的 error log信息。<br>nginx把对php的请求发给php-fpm fastcgi进程来处理，默认的php-fpm只会输出php-fpm的错误信息，在php-fpm的errors log里也看不到php的errorlog<br>原因是php-fpm的配置文件php-fpm.conf中默认是关闭worker进程的错误输出，直接把他们重定向到/dev/null,所以我们在nginx的error log 和php-fpm的errorlog都看不到php的错误日志。</p>
<p>1、修改php-fpm.conf中配置</p>
<blockquote>
<p>catch_workers_output = yes<br>error_log = log/error_log</p>
</blockquote>
<p>2、修改php.ini中配置</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">log_errors = On</span><br><span class="line">error_log = "/var/log/php/error_log" # 填写日志路径</span><br><span class="line">error_reporting = E_ALL&~E_NOTICE</span><br></pre></td></tr></table></figure>
<p>3、重启php-fpm<br>注意：<br>a、php-fpm.conf 中的php_admin_value[error_log] 参数 会覆盖php.ini中的 error_log 参数<br>所以确保你在phpinfo()中看到的最终error_log文件具有可写权限并且没有设置php_admin_value[error_log] 参数，否则错误日志会输出到php-fpm的错误日志里</p>
<p>b、找不到php.ini位置，使用php的phpinfo()结果查看<br>c、如何修改PHP错误日志不输出到页面或屏幕上</p>
<p>修改php.ini</p>
<blockquote>
<p>不显示错误信息(不输出到页面或屏幕上)<br>display_errors = off<br>记录错误信息(保存到日志文件中)<br>log_errors = on<br>捕获所有错误信息<br>error_reporting = E_ALL<br>设置日志文件名<br>error_log = </p>
</blockquote>
<p>程序中修改以上配置</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">ini_set("display_errors", 0)</span><br><span class="line">ini_set("error_reporting", E_ALL); </span><br><span class="line">ini_set("error_log", "<日志文件名>")</span><br><span class="line">ini_set("log_errors", 1);</span><br></pre></td></tr></table></figure>]]></content>

<p> 包、变量、函数</p>
</blockquote>
<ul>
<li><p>包<br>每个 Go 程序都是由包组成的。程序运行的入口是包 <code>main</code><br>这个程序使用并导入了包 “fmt” 和 <code>"math/rand"</code>。如：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">package main</span><br><span class="line"></span><br><span class="line">import (</span><br><span class="line"> "fmt"</span><br><span class="line"> "math/rand"</span><br><span class="line">)</span><br></pre></td></tr></table></figure>
</li>
<li><p>变量<br>var 语句定义了一个变量的列表 如：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">var c, python, java bool</span><br><span class="line">var i, j int = 1, 2</span><br><span class="line"></span><br><span class="line">func main() {</span><br><span class="line"> var i int</span><br><span class="line"> /*在函数中，`:=` 简洁赋值语句在明确类型的地方，可以用于替代 var 定义</span><br><span class="line"> 函数外的每个语句都必须以关键字开始（`var`、`func`、等等），`:=` 结构不能使用在函数外*/</span><br><span class="line"> k := 3</span><br><span class="line"> var c, python, java = true, false, "no!"</span><br><span class="line"> ...</span><br><span class="line">}</span><br><span class="line"></span><br></pre></td></tr></table></figure></li>
<li><p>函数<br>函数可以没有参数或接受多个参数<br>在这个例子中，<code>add</code> 接受两个 int 类型的参数。如：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">func add(x int, y int) int {</span><br><span class="line"> return x + y</span><br><span class="line">}</span><br><span class="line">||</span><br><span class="line">func add(x , y int) int {</span><br><span class="line"> return x + y</span><br><span class="line">}</span><br><span class="line"></span><br></pre></td></tr></table></figure>
</li>
</ul>
<blockquote>
<p> 流程控制语句</p>
</blockquote>
<ul>
<li><p>for<br>Go 只有一种循环结构——<code>for</code> 循环<br>基本的 for 循环除了没有了 <code>( )</code> 之外（甚至强制不能使用它们）。如：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">func main() {</span><br><span class="line"> sum := 0</span><br><span class="line"> for i := 0; i < 10; i++ {</span><br><span class="line"> sum += i</span><br><span class="line"> }</span><br><span class="line"> fmt.Println(sum)</span><br><span class="line">}</span><br><span class="line"></span><br></pre></td></tr></table></figure>

</li>
<li><p>defer<br>defer 语句会延迟函数的执行直到上层函数返回。<br>延迟调用的参数会立刻生成，但是在上层函数返回前函数都不会被调用。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">func main() {</span><br><span class="line"> defer fmt.Println("world")//延迟函数</span><br><span class="line"> fmt.Println("hello") //上层函数</span><br><span class="line">}</span><br><span class="line">//hello</span><br><span class="line">//wolrd</span><br></pre></td></tr></table></figure>

<title>Laragon 在 Windows 中搭建 Laravel 开发环境</title>
<url>/2017/09/15/Laragon-%E5%9C%A8-Windows-%E4%B8%AD%E6%90%AD%E5%BB%BA-Laravel-%E5%BC%80%E5%8F%91%E7%8E%AF%E5%A2%83/</url>
<content><![CDATA[<a id="more"></a>
<p><strong>一、简介</strong></p>
<blockquote>
<p>之前coder陆续写了三篇介绍 Laravel 开发环境的教程：Homestead、Valet 和 LaraDock，我都是在 Mac 系统中安装使用的，相当流畅，没有任何梗，但是对于那些使用 Windows 的同学来说，Valet 就不说了，Homestead 和 LaraDock 虽说支持 Windows 系统，但是对小白来说，还是有一定复杂度的，难免有些磕磕跘跘，遇到这样那样的奇怪问题，可能大部分人会退而继续使用 Xampp、Wamp、phpStudy 之类集成工具，今天学院君要给大家推荐一款可能更加容易使用的 Windows 集成开发环境，更重要的是，它对 Laravel 非常友好，它的名字叫做 Laragon。Laragon 具备以下优秀的特性：</p>
</blockquote>
<ul>
<li> 自动创建虚拟主机（Virtual Host，Valet 也有这样的功能）</li>
<li> 邮件接收和发送</li>
<li> 非常方便地切换 PHP、Apache、MySQL 的不同版本</li>
<li> 轻松创建框架应用，如 Laravel、Symfony、WordPress、Joomla 等</li>
<li> 基于自己的需求为不同的环境设置不同的配置</li>
</ul>
<blockquote>
<p> 所以，从今天起，可以抛弃那些传统的集成开发环境了，Windows 上也可以搭建优雅的开发环境！</p>
</blockquote>
<p><strong>二、安装</strong></p>
<blockquote>
<p> 我们可以在这里下载 Laragon：<a href="https://sourceforge.net/projects/laragon/" target="_blank">[ laragon ]</a> Windows下的软件安装就不需多言了吧，注意在这一步勾选下 Auto virtual hosts（我的虚拟机语言选择中文乱码，所以使用了英文界面，你们可以自己根据喜好进行设置）：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/1.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 然后下一步点击安装即可。下面是 Laragon 启动后的界面：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/2.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 要启动 Apache、MySQL 服务，需要点击 Start All 按钮：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/3.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 这样点击 Web 即可打开浏览器访问默认站点 <a href="http://localhost：">http://localhost：</a></p>
</blockquote>
<p><img src="/assets/blogImg/laragon/4.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 要访问数据库，可以点击 Database 按钮：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/5.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 默认数据库是 Laragon，用户名是 root，密码是空字符串，点击打开按钮，就可以访问这个默认的数据库：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/6.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 点击 Laragon 界面的 Terminal 按钮可以进入到一个类 Unix 的终端工具 Cmder 进行命令行操作：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/7.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 最后，Laragon 界面还有一个 Root 按钮，点击之后即可进入 Laragon 文档根目录，我的 Laragon 安装在 C 盘下，所以对应的文档根目录是 C:\laragon\www</p>
</blockquote>
<blockquote>
<p> 此外，Laragon 界面右上角还有个齿轮按钮，点击可以对系统进行设置，比如我们可以设置语言为简体中文：：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/8.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 文件根目录：目录地址是可以修改的 若有自己的项目根目录，可以选择自己的根目录.然后再通过点击终端进去 进入根目录试用下命令模式 重新加载下<br>nginx、Apache 下次进入终端就是自己设置的默认根目录下了.</p>
</blockquote>
<p><strong>三、自动创建虚拟主机</strong></p>
<blockquote>
<p> 和 Valet 类似，当你在 Laragon 文档根目录下创建新的文件夹时，启动 Laragon 就会自动为你创建虚拟主机，默认主机域名是 <a href="http://folder_name.dev,在浏览器中访问这个域名就能看到/">http://folder_name.dev，在浏览器中访问这个域名就能看到</a> Web 页面了，是不是很方便？我们可以在命令行中使用 Laravel 安装器安装一个 blog 应用（不知道怎么操作？可以参考<a href="https://shunhua.github.io/2017/09/15/laravel5.5%E5%BF%AB%E9%80%9F%E5%85%A5%E9%97%A8-%E2%80%94%E2%80%94-%E5%AE%89%E8%A3%85%E9%85%8D%E7%BD%AE%E7%AF%87/" target="_blank">[ 安装配置文档 ]</a> 中的安装部分）：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/9.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 那么在重新加载 Apache 服务器之后，就可以在浏览中通过 <a href="http://blog.dev/">http://blog.dev</a> 访问刚刚创建的应用了：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/10.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 是不是很nice？如果你想将域名后缀 .dev 改成其它如 .com 可以通过点击 Laragon 界面上的齿轮按钮对默认配置进行修改：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/11.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 将 .env 改成 .com 重新加载 Apache 服务即可通过 <a href="http://blog.com/">http://blog.com</a> 访问站点。</p>
</blockquote>
<p><strong>四、切换 PHP、Apache 和 MySQL 版本</strong></p>
<blockquote>
<p> 你可以通过点击 Laragon 界面上的菜单来切换不同软件的版本：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/12.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 现在默认安装的 Laragon 每个软件都只有一个版本，以 PHP 为例如果想要支持多个版本的切换和测试，需要到 <a href="http://windows.php.net/download/">http://windows.php.net/download/</a> 去下载不同版本（需要下载 Non Thread Safe 版本），然后将下载后的文件解压到 C:\laragon\bin\php （注意这里的目录以你的Laragon安装目录为准，比如我的就是安装在 C:\laragon）目录下：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/13.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 这样就可以进行版本切换了：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/14.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 切换 MySQL 和 Apache 的版本也是类似，这里不再赘述，一般这种场景也不多。</p>
</blockquote>
<p><strong>五、启用 Nginx 替代 Apache</strong></p>
<blockquote>
<p> 如果你想要使用 Nginx 作为 Web 服务器，也可以轻松实现，在配置里面取消勾选 Apache，改为勾选 Nginx 然后修改绑定端口为 80 即可：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/18.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 启用 Memcached 和 Redis 也只需要勾选上相应的配置项即可，非常方便。配置完成后，Laragon 会自动关闭 Apache 并启动 Nginx 服务器：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/19.jpg" alt="ico原来的样子"></p>
<p>然后，在浏览器中访问 <a href="http://blog.dev,没有任何问题,平稳过渡,大功告成./">http://blog.dev，没有任何问题，平稳过渡，大功告成。</a></p>
<p><strong>六、快速创建 Laravel 应用</strong></p>
<blockquote>
<p> 上面我们通过 Laravel 安装器创建了一个新的 Laravel 应用，其实已经很方便了，但是还有更方便的，我们通过点击”菜单->快速创建->Laravel”可以不用敲任何命令就可以安装一个 Laravel 应用：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/15.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 在弹出的窗口中输入应用的名称：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/16.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> 点击Ok后就会弹出命令行窗口为我们创建应用：</p>
</blockquote>
<p><img src="/assets/blogImg/laragon/17.jpg" alt="ico原来的样子"></p>
<blockquote>
<p> Laragon 还有更多功能等着你去挖掘，比如也支持基于 Ngrok 进行站点分享，支持 Node、Putty、Yarn、文件传输等等，欢迎你在使用的过程中与我们分享。</p>

<title>Laravel Redis 广播测试</title>
<url>/2019/04/19/Laravel-Redis-%E5%B9%BF%E6%92%AD%E6%B5%8B%E8%AF%95/</url>
<content><![CDATA[<a id="more"></a>
<p> 附上 <a href="https://github.com/shunhua/laravel-echo" target="_blank">[Github]</a> 地址 </p>
<p> 一、项目搭建<br> a.安装laravel</p>
<blockquote>
<p>composer create-project –prefer-dist laravel/laravel echo</p>
</blockquote>
<p> b.配置mysql 数据库</p>
<blockquote>
<p>php artisan migrate</p>
</blockquote>
<p> c.快速认证</p>
<blockquote>
<p>php artisan make:auth</p>
</blockquote>
<p> 本文仅使用了 redis 的广播驱动 测试环境 win10<br> 二、安装redis 并启动</p>
<blockquote>
<p>redis-server.exe</p>
</blockquote>
<p><img src="/assets/blogImg/guangbo/redis.png" alt="ico原来的样子"><br>测试redis 连接成功<br><img src="/assets/blogImg/guangbo/redis1.png" alt="ico原来的样子"></p>
<p>a.配置文件 .env 中配置以下代码</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">BROADCAST_DRIVER=redis</span><br></pre></td></tr></table></figure>
<p>b.广播服务提供者 config/app.php 配置文件中 providers 数组中打开注释</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">App\Providers\BroadcastServiceProvider::class,</span><br></pre></td></tr></table></figure>
<p>c.CSRF 令牌[后续视图中添加]</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><meta name="csrf-token" content="{{ csrf_token() }}"></span><br></pre></td></tr></table></figure>
<p>d.安装 Predis 库</p>
<blockquote>
<p>composer require predis/predis</p>
</blockquote>
<p>三、安装 Laravel Echo</p>
<p>a.通过 npm 包管理器安装 Echo</p>
<blockquote>
<p>npm install<br> npm install -g laravel-echo-server</p>
</blockquote>
<p>b.初始化 laravel-echo-server</p>
<blockquote>
<p>laravel-echo-server init</p>
</blockquote>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">// 是否在开发模式下运行此服务器（y/n） 输入y</span><br><span class="line">? Do you want to run this server in development mode? (y/N) </span><br><span class="line">// 设置服务器的端口 默认 6001 输入 6001就可以了 或者你想要的</span><br><span class="line">? Which port would you like to serve from? (6001)</span><br><span class="line">// 想用的数据库 选择 redis</span><br><span class="line">? Which database would you like to use to store presence channel members? (Use arrow keys)</span><br><span class="line">❯ redis </span><br><span class="line"> sqlite </span><br><span class="line">// 这里输入 你的laravel 项目的访问域名</span><br><span class="line">? Enter the host of your Laravel authentication server. (http://localhost) </span><br><span class="line">// 选择 网络协议 http</span><br><span class="line">? Will you be serving on http or https? (Use arrow keys)</span><br><span class="line">❯ http </span><br><span class="line"> https </span><br><span class="line">// 您想为HTTP API生成客户端ID/密钥吗 N</span><br><span class="line">? Do you want to generate a client ID/Key for HTTP API? (y/N) </span><br><span class="line">// 要设置对API的跨域访问吗？（y/n）N</span><br><span class="line">Configuration file saved. Run laravel-echo-server start to run server.</span><br></pre></td></tr></table></figure>
<p>设置完成后 项目根目录 下 会生成 laravel-echo-server.json 文件 这里面就是刚才的配置<br><img src="/assets/blogImg/guangbo/echo.png" alt="ico原来的样子"><br>执行命令启动 服务 出现如下 则启动成功</p>
<blockquote>
<p>laravel-echo-server start</p>
</blockquote>
<p><img src="/assets/blogImg/guangbo/echo1.png" alt="ico原来的样子"></p>
<p>四、频道<br>频道Channel、PrivateChannel 或 PresenceChannel 的实例。Channel 实例表示任何用户都可以订阅的公开频道，而 PrivateChannels 和 PresenceChannels 则表示需要 频道授权 的私有频道：<br>a.创建事件</p>
<blockquote>
<p>php artisan make:event PublicMessageEvent </p>
</blockquote>
<p>文件生成目录 app/Events</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">public $message;</span><br><span class="line"></span><br><span class="line">/**</span><br><span class="line"> * Create a new event instance.</span><br><span class="line"> *</span><br><span class="line"> * @param User $user</span><br><span class="line"> * @param string $message</span><br><span class="line"> */</span><br><span class="line">public function __construct(string $message)</span><br><span class="line">{</span><br><span class="line"> $this->message = $message;</span><br><span class="line">}</span><br><span class="line"></span><br><span class="line">/**</span><br><span class="line"> * Get the channels the event should broadcast on.</span><br><span class="line"> *</span><br><span class="line"> * @return \Illuminate\Broadcasting\Channel|array</span><br><span class="line"> */</span><br><span class="line">public function broadcastOn()</span><br><span class="line">{</span><br><span class="line"> return new Channel('push');</span><br><span class="line">}</span><br><span class="line"></span><br><span class="line">//Laravel 默认会使用事件的类名作为广播名称来广播事件，自定义：</span><br><span class="line">public function broadcastAs()</span><br><span class="line">{</span><br><span class="line"> return 'push.message';</span><br><span class="line">}</span><br><span class="line"></span><br><span class="line">//想更细粒度地控制广播数据:</span><br><span class="line">public function broadcastWith()</span><br><span class="line">{</span><br><span class="line"> return ['message' => $this->message,'status' => 'okok'];</span><br><span class="line">}</span><br><span class="line"></span><br><span class="line">// laravel-echo-server 1.5 版本的 需要添加 否则Laravel echo channel listen 不监听事件</span><br><span class="line">public function handle()</span><br><span class="line">{</span><br><span class="line"> broadcast(new push());</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>b.添加路由</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">use App\Events\PublicMessageEvent;</span><br><span class="line"> Route::get('/echo', function () {</span><br><span class="line"> return view('echo');</span><br><span class="line"> });</span><br><span class="line"></span><br><span class="line">Route::get('/push/{message}', function ($message) {</span><br><span class="line"> broadcast(new PublicMessageEvent($message));</span><br><span class="line">})</span><br></pre></td></tr></table></figure>
<p>五、前端视图<br>a.安装 laravel-echo</p>
<blockquote>
<p>npm install laravel-echo</p>
</blockquote>
<p>编辑 resource/js/bootstrap.js 添加如下代码</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">import Echo from "laravel-echo"</span><br><span class="line"></span><br><span class="line">window.Echo = new Echo({</span><br><span class="line"> broadcaster: 'socket.io',</span><br><span class="line"> host: window.location.hostname + ':6001'</span><br><span class="line">});</span><br></pre></td></tr></table></figure>
<p>编辑 resource/js/app.js 添加如下代码</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">Echo.channel('push')</span><br><span class="line"> .listen('.push.message', (e) => {</span><br><span class="line"> alert(e.message)</span><br><span class="line"> console.log(e);</span><br><span class="line"> });</span><br></pre></td></tr></table></figure>
<p>创建 echo.blade.php head 中加上</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line"><meta name="csrf-token" content="{{ csrf_token() }}"></span><br><span class="line"><script src="//{{ Request::getHost() }}:6001/socket.io/socket.io.js"></script></span><br><span class="line"><script src="/js/app.js"></script></span><br></pre></td></tr></table></figure>
<p>编译 js 文件 </p>
<blockquote>
<p>npm run watch</p>
</blockquote>
<p>浏览器访问 项目域名 /echo<br>浏览器访问 项目域名 /push/这是一个测试广播[what can i say]<br>echo 页面 会自动弹出<br><img src="/assets/blogImg/guangbo/echo2.png" alt="ico原来的样子"><br><img src="/assets/blogImg/guangbo/echo4.png" alt="ico原来的样子"><br><img src="/assets/blogImg/guangbo/echo5.png" alt="ico原来的样子"><br>到这 广播 发布到公共频道就完成了</p>
<hr>
<p>私有频道 PrivateChannel</p>
<blockquote>
<p>php artisan make:event PrivateMessageEvent</p>
</blockquote>
<p>PrivateMessageEvent 中 写入 以下内容</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">public $message;</span><br><span class="line"> public $user;</span><br><span class="line"></span><br><span class="line"> /**</span><br><span class="line"> * Create a new event instance.</span><br><span class="line"> *</span><br><span class="line"> * @param User $user</span><br><span class="line"> * @param string $message</span><br><span class="line"> */</span><br><span class="line"> public function __construct(User $user, string $message)</span><br><span class="line"> {</span><br><span class="line"> $this->user = $user;</span><br><span class="line"> $this->message = $message;</span><br><span class="line"> }</span><br><span class="line"></span><br><span class="line"> /**</span><br><span class="line"> * Get the channels the event should broadcast on.</span><br><span class="line"> *</span><br><span class="line"> * @return \Illuminate\Broadcasting\Channel|array</span><br><span class="line"> */</span><br><span class="line"> public function broadcastOn()</span><br><span class="line"> {</span><br><span class="line"> return new PrivateChannel('privatePush.' . $this->user->id);</span><br><span class="line"> }</span><br><span class="line"></span><br><span class="line"> //想更细粒度地控制广播数据:</span><br><span class="line"> public function broadcastWith()</span><br><span class="line"> {</span><br><span class="line"> return ['message' => $this->message,'status' => 'okok'];</span><br><span class="line"> }</span><br></pre></td></tr></table></figure>
<p>添加发布广播到私有频道 触发路由 routes/web 测试时记得新增下用户</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">Route::get('/privatePush/{message}/{id}', function ($message, $id) {</span><br><span class="line"> $user = \App\User::find($id);</span><br><span class="line"> if (empty($user)) return '无此用户';</span><br><span class="line"> broadcast(new PrivateMessageEvent($user, $message));</span><br><span class="line">});</span><br></pre></td></tr></table></figure>
<p>echo.blade.php 中加入</p>
