如何获取boost :: asio :: ip :: tcp :: socket的IP地址?
问题描述：
我正在使用Boost ASIO库用C ++编写服务器.我想将客户端IP的字符串表示形式显示在服务器的日志中.有人知道怎么做吗?
I'm writing a server in C++ using Boost ASIO library. I'd like to get the string representation of client IP to be shown in my server's logs. Does anyone know how to do it?

套接字具有将检索远程端点的功能.我会继续使用这条(长距离的)命令链，它们应该检索远端IP地址的字符串表示形式:
The socket has a function that will retrieve the remote endpoint. I'd give this (long-ish) chain of commands a go, they should retrieve the string representation of the remote end IP address:
asio::ip::tcp::socket socket(io_service);
// Do all your accepting and other stuff here.
asio::ip::tcp::endpoint remote_ep = socket.remote_endpoint();
asio::ip::address remote_ad = remote_ep.address();
std::string s = remote_ad.to_string();
或单线版本:
asio::ip::tcp::socket socket(io_service);
// Do all your accepting and other stuff here.
std::string s = socket.remote_endpoint().address().to_string();
