本文介绍了一个简单的WebSocket服务器实现过程，使用了websocketpp库进行消息处理。该服务器能够在客户端连接、断开连接时输出日志，并接收客户端发送的消息，再将带有前缀的回应消息发送回客户端。

#include "stdafx.h"
#include <iostream>
 
using namespace std;
 
#include <websocketpp/config/asio_no_tls.hpp>
#include <websocketpp/server.hpp>
 
typedef websocketpp::server<websocketpp::config::asio> WebsocketServer;
typedef WebsocketServer::message_ptr message_ptr;
 
using websocketpp::lib::placeholders::_1;
using websocketpp::lib::placeholders::_2;
using websocketpp::lib::bind;
 
void OnOpen(WebsocketServer *server, websocketpp::connection_hdl hdl)
{
  cout << "have client connected" << endl;
}
 
void OnClose(WebsocketServer *server, websocketpp::connection_hdl hdl)
{
  cout << "have client disconnected" << endl;
}
 
void OnMessage(WebsocketServer *server, websocketpp::connection_hdl hdl, message_ptr msg)
{
  string strMsg = msg->get_payload();
  cout << strMsg << endl;
 
  string strRespon = "receive: ";
  strRespon.append(strMsg);
 
  server->send(hdl, strRespon, websocketpp::frame::opcode::text);
}
 
int main()
{
  WebsocketServer          server;
 
  // Set logging settings
  server.set_access_channels(websocketpp::log::alevel::all);
  server.clear_access_channels(websocketpp::log::alevel::frame_payload);
 
  // Initialize ASIO
  server.init_asio();
 
  // Register our open handler
  server.set_open_handler(bind(&OnOpen, &server, ::_1));
 
  // Register our close handler
  server.set_close_handler(bind(&OnClose, &server, _1));
 
  // Register our message handler
  server.set_message_handler(bind(&OnMessage, &server, _1, _2));
 
  //Listen on port 2152
  server.listen(8090);
 
  //Start the server accept loop
  server.start_accept();
 
  //Start the ASIO io_service run loop
  server.run();
 
  return 0;
}
