[项目][WebServer][Task]详细讲解

1.Task类

class Task
{
public:void ProcessOn(){_handler(_sock);}Task(){}Task(int sock): _sock(sock){}~Task(){}
private:int _sock;CallBack _handler; // 设置回调
};

2.CallBack类

• 读取出错处理
  • 读取请求时可能出错，此时读取到的请求是一个错误请求，那么就没有往下解析执行的必要了，故在RecvRequest()返回之后，做以下设计

    ep->RecvRequest();
    if(!ep->IsStop()) // 只有读取请求不出错，才往下执行
    {LOG(INFO, "Recv No Error, Continue Build And Send");ep->BuildResponse();ep->SendResponse();
    }
    else
    {LOG(WARNING, "Recv Error, Stop Build And Send");
    }
    

struct CallBack
{// 重载() --> 仿函数void operator()(int sock){HandlerRequest(sock);}void HandlerRequest(int sock){LOG(INFO, "Hander Request Begin");EndPoint *ep = new EndPoint(sock); // TODOep->RecvRequest();if(!ep->IsStop()) // 只有读取请求不出错，才往下执行{LOG(INFO, "Recv No Error, Continue Build And Send");ep->BuildResponse();ep->SendResponse();}else{LOG(WARNING, "Recv Error, Stop Build And Send");}delete ep; LOG(INFO, "Hander Request End");}CallBack(){}~CallBack(){}
};
