HttpBypass

介绍

FPNN 数据以 HTTP 的方式，旁路到指定的 URL。

注意

• 本模块必须由配置文件驱动。

  配置条目为：

    # split by ";, "
    HTTPBypass.methods.list =
    # ? 为 methods 里表中对应的 method
    HTTPBypass.method.?.url =
    # timeout 默认 120 秒
    HTTPBypass.Task.timeoutSeconds =
  

  例 1:

    HTTPBypass.methods.list = deomHethod
    HTTPBypass.method.deomHethod.url = http://demo.com/s/deomHethodInterface
  

  例 2:

    HTTPBypass.methods.list = liveStart, liveFinish, watchLive
    HTTPBypass.method.liveStart.url = http://demo.com/s/liveStart
    HTTPBypass.method.liveFinish.url = http://demo.com/s/liveFinish
    HTTPBypass.method.watchLive.url = http://demo.com/s/watchLive
  

  如果服务没有自己的 MultipleURLEngine， 或者希望 HTTPBypass 使用独立的 MultipleURLEngine，则须要增加以下条目：

    HTTPBypass.URLEngine.connsInPerThread = 
    HTTPBypass.URLEngine.ThreadPool.initCount = 
    HTTPBypass.URLEngine.ThreadPool.perfectCount = 
    HTTPBypass.URLEngine.ThreadPool.maxCount = 
    HTTPBypass.URLEngine.maxConcurrentTaskCount =
    HTTPBypass.URLEngine.ThreadPool.latencySeconds =
  

  HttpBypass 具体配置项目亦可参见 HttpBypass.h 的头部注释。

命名空间

namespace fpnn;

关键定义

class HttpBypass
{
public:
	HttpBypass(std::shared_ptr<MultipleURLEngine> engine = nullptr);
	~HttpBypass();
	void bypass(const FPQuestPtr quest);
};
typedef std::shared_ptr<HttpBypass> HttpBypassPtr;

构造函数

HttpBypass(std::shared_ptr<MultipleURLEngine> engine = nullptr);

参数说明

• std::shared_ptr<MultipleURLEngine> engine

  多路 URL 并发访问引擎 MultipleURLEngine。如果值为 nullptr，HttpBypass 将通过配置文件，初始化私有的 MultipleURLEngine。

成员函数

bypass

void bypass(const FPQuestPtr quest);

旁路指定的请求数据。

当旁路失败时，不会重试。相关信息将会以 ERROR 级别，输出到日志中。日志请参考：FPLog。
