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?
You can use gethostname followed by gethostbyname to get your local interface internal IP.
Boost. Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach. Overview.
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();
or the one-liner version:
asio::ip::tcp::socket socket(io_service);
// Do all your accepting and other stuff here.
std::string s = socket.remote_endpoint().address().to_string();
Or, even easier, with boost::lexical_cast
:
#include <boost/lexical_cast.hpp>
std::string s = boost::lexical_cast<std::string>(socket.remote_endpoint());
