Question

我正在开发一个基于C ++ ASIO的应用程序。参考Chat Server

我的服务器类：

class CServer  {

public:

    CServer(asio::io_service& io_service, const std::string serIdentity, std::string IP, const std::string port);
    ~CServer();

    void listen();
    void handle_accept(sessionPtr newSession, const asio::error_code& error);
private:

    tcp::acceptor acceptor_; // only in the listener
    asio::io_service& io_;
    CSerSessionsManager mng_;

};

void CServer::listen()
{
sessionPtr newSession = std::make_shared<channel::CSerSession>(io_, mng_, serIdentifier_, ip_, port_);

    acceptor_.async_accept(newSession->socket(), std::bind(&CServer::handle_accept, this, newSession,
                std::placeholders::_1));
} 

    void CServer::handle_accept(sessionPtr newSession, const asio::error_code& error)
{
    if (!error)
    {
        //Do Something
        listen();
    }
    else
    {
        DEBUG_MSG("Listen_Error");
        //Returning from here throws Exception
    }

}

当我的CServer Object在拨打~CServer() 之后销毁时，会设置Handle Accept错误，因为现有的默认收听会话处于活动状态。从handle_accept()返回时，它会抛出异常。

Unhandled exception at 0x74E8C42D in channel.exe: Microsoft C++ exception: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::system_error> > at memory location 0x023EF3EC.

下面的

是调用堆栈：

    channel.exe!asio::detail::win_thread_function(void * arg) Line 109  C++

我与session class destruction Asked Here

有类似的问题

如何解决此问题并确保在调用~CServer()时彻底退出。
