C或C++ websocket客户端工作示例

#include <iostream>
#include <websocketpp/config/asio_client.hpp>
#include <websocketpp/client.hpp>

typedef websocketpp::client<websocketpp::config::asio_client> client;

    std::string uri = "ws://example.com/websocket"; // WebSocket服务器的URI

            std::cout << "Connected to server" << std::endl;
        });

        c.set_message_handler([](websocketpp::connection_hdl hdl, client::message_ptr msg) {

            return 0;
