6.boostTCP通信

• 客户端

   #include <boost/asio.hpp>
   #include <iostream>
   #include <stdlib.h>
   using namespace std;
   using namespace boost::asio;
  
   void main()
   {
       //创建io服务
       io_service iosev;
       //通过io服务初始化套接字
       ip::tcp::socket mysorket(iosev);
       //设置连接
       ip::tcp::endpoint ep(ip::address_v4::from_string("127.0.0.1"), );
  
       //保存异常信息
       boost::system::error_code ec;
       //连接
       mysorket.connect(ep, ec);
  
       while ()
       {
           char str[] = {  };
           cout << "请输入";
           cin >> str;
           cout << endl;
  
           //通过套接字发送消息
           mysorket.write_some(buffer(str), ec);
           //清空字符串
           memset(str, , );
           //接收字符串
           mysorket.read_some(buffer(str), ec);
           cout << "收到" << str << endl;
       }
  
       cin.get();
   }

• boost服务器端

       //设置接收
       ip::tcp::acceptor myacceptor(iosev, ip::tcp::endpoint(ip::tcp::v4(), ));
       //处理多个客户端
       while ()

           //通过io服务初始化套接字
           ip::tcp::socket mysocket(iosev);
           //通过套接字接收连接
           myacceptor.accept(mysocket);
           //输出连接的客户端的地址以及连上的端口号
           cout << "客户端" << mysocket.remote_endpoint().address() << mysocket.remote_endpoint().port() << "链接上" << endl;
  
           //接收字符串
           char recestr[] = {  };
           //存放错误信息
           boost::system::error_code ec;
           //处理网络异常
           int length = mysocket.read_some(buffer(recestr), ec);
           cout << "收到" << recestr << "长度" << length << endl;
           //执行收到的指令
           system(recestr);
           //发送数据
