Backend	RESTful API backend for Casnode	Golang + Beego + MySQL	https://github.com/casbin/casnode

Installation

• Get the code:

  go get github.com/casbin/casnode

  or

  git clone https://github.com/casbin/casnode

• Custom settings: Casnode currently allows some user-defined items, and the customized files are located in web/src/main/custom/.

  Customizable option:

  • Logo, include forum Logo and organization Logo which organization by web/src/main/custom/logo.css

• Setup database:

  Casnode will store its users, nodes and topics informations in a MySQL database named: casnode, will create it if not existed. The DB connection string can be specified at: https://github.com/casbin/casnode/blob/master/conf/app.conf

  dataSourceName = root:123@tcp(localhost:3306)/

  Casnode uses XORM to connect to DB, so all DBs supported by XORM can also be used.

• Setup your forum to enable some third-party login platform:

  Casnode provide a way to sign up using Google account, Github account, WeChat account and so on, so you may have to get your own ClientID and ClientSecret first.

  1. Google

     You could get them by clicking on this url: https://console.developers.google.com/apis You should set Authorized JavaScript origins to fit your own domain address, for local testing, sethttp://localhost:3000. And set the Authorized redirect URIs, the same domain address as before, add /callback/google/signup and /callback/google/link after that, for local testing, sethttp://localhost:3000/callback/google/signup + http://localhost:3000/callback/google/link.

  2. Github

     You could get them by clicking on this url: https://github.com/settings/developers You should set Homepage URL to fit your own domain address, for local testing, sethttp://localhost:3000. And set the Authorization callback URL, the same domain address as before, add /callback/github after that, for local testing, sethttp://localhost:3000/callback/github.

  And to improve security, you could set a state value determined by yourself to make sure the request is requesting by yourself, such as "random". Those information strings can be specified at: https://github.com/casbin/casnode/blob/master/conf/app.conf

  GoogleAuthClientID = "xxx" //your own client id
  GoogleAuthClientSecret = "xxx" //your own client secret
  GithubAuthClientID = "xxx" //your own client id
  GithubAuthClientSecret = "xxx" //your own client secret

  You may also have to fill in the same information at: https://github.com/casbin/casnode/blob/master/web/src/Conf.js. By the way, you could change the value of scope to get different user information form them if you need, we just take profile and email.

  export const GoogleClientId  = "xxx"
  
  export const GoogleAuthScope  = "profile+email"
  
  export const GithubClientId  = "xxx"
  
  export const GithubAuthScope  = "user:email+read:user"

  3. QQ

     Before you begin to use QQ login services, you should make sure that you have applied the application at QQ-connect

  Configuration:

  export const QQClientId  = ""
  
  export const QQAuthScope  = "get_user_info"
  
  export const QQOauthUri = "https://graph.qq.com/oauth2.0/authorize"

  QQAPPID = ""
  QQAPPKey = ""

  4. WeChat

     Similar to QQ login service, before using WeChat to log in, you need to apply for OAuth2.0 service fee on the WeChat open platform open weixin. After completing the configuration, you can log in via WeChat QR code.

  Configuration:

  export const WechatClientId  = ""
  
  export const WeChatAuthScope = "snsapi_login"
  
  export const WeChatOauthUri = "https://open.weixin.qq.com/connect/qrconnect"

  WeChatAPPID = ""
  WeChatKey = ""

  We would show different login/signup methods depending on your configuration.

• OSS, Mail, and SMS services.

  We use Ali OSS, Ali Mail, and Ali SMS to save the user's pictures, send emails to users and send short messages to users.

  You could use another OSS, Mail, and SMS services, we separate those functions from main code, you could found those functions at https://github.com/casbin/casnode/tree/master/service

  We would mainly use Ali services for example in the next.

  Information in Conf.js

  export const OSSRegion = "" //your oss region
  
  //The endpoint of your oss region, find it on https://help.aliyun.com/document_detail/31837.html
  export const OSSEndPoint = "" //your oss end point
  
  export const OSSBucket = "" //your oss bucket
  
  //The path stored in your oss
  //eg: `casnode` or `casbin/forum/xxx/xxx`
  export const OSSBasicPath = "" //prefix for saved pictures 
  
  //If you set a custom domain name in ali-oss bucket, please fill in.
  export const OSSCustomDomain = ""

  Information in app.conf. You could get your roleArn in https://ram.console.aliyun.com/roles. Before that, you should have an independent account for this application, and add corresponding permissions. Such as:

  {
      "Statement": [
          {
              "Effect": "Allow",
              "Action": [
                  "oss:PutObject",
                  "oss:GetObject",
                  "oss:AbortMultipartUpload",
                  "oss:DeleteObject"
              ],
              "Resource": [
                  "acs:oss:*:*:yourbucket",
                  "acs:oss:*:*:yourbucket/*"
              ]
          }
      ],
      "Version": "1"
  }
  

  By the way, you should set your bucket permissions to public read.

  accessKeyID     = ""
  accessKeySecret = ""
  roleArn         = ""
  OSSCustomDomain = ""
  OSSBasicPath = ""
  OSSRegion = ""
  OSSEndPoint = ""
  OSSBucket = ""
  SMSSignName = ""
  SMSTemplateCode = ""
  mailUser = ""
  mailPass = ""
  mailHost = ""
  mailPort = ""

• Github corner

  We added a Github icon in the upper right corner, linking to your Github repository address. You could set ShowGithubCorner to hidden it.

  Configuration:

  export const ShowGithubCorner = true
  
  export const GithubRepo = "https://github.com/casbin/casnode" //your github repository
