7.boostUDP通信

• 客户端

   #include <iostream>
   #include<string>
   #include <boost/asio.hpp>
   #include <stdlib.h>
   using namespace std;
   using namespace boost::asio;
  
   void main()
   {
       //一个服务的类，给这个UDP通信初始化
       io_service io_serviceA;
       //通过服务给这个UDP通信初始化
       ip::udp::socket udp_socket(io_serviceA);
       //设置连接的IP还有端口
       ip::udp::endpoint local_add(ip::address::from_string("127.0.0.1"), );
       //添加协议
       udp_socket.open(local_add.protocol());
       char receive_str[] = {  };//字符串
  
       while ()
       {
           string sendstr;
           cout << "请输入";
           cin >> sendstr;
           cout << endl;
           udp_socket.send_to(buffer(sendstr.c_str(), sendstr.size()), local_add);
           udp_socket.receive_from(buffer(receive_str, ), local_add);
           cout << "收到" << receive_str << endl;
       }
  
       system("pause");
   }

• 服务器端

   #include <iostream>
   #include<string>
   #include <boost/asio.hpp>
   #include <stdlib.h>
  
   using namespace std;
   using namespace boost::asio;
   void main()
   {
       //一个服务的类，给这个UDP通信初始化
       io_service io_serviceA;
       //给这个UDP通信初始化
       ip::udp::socket udp_socket(io_serviceA);
       //绑定IP还有端口
       ip::udp::endpoint local_add(ip::address::from_string("127.0.0.1"), );
  
       //添加协议
       udp_socket.open(local_add.protocol());
       //绑定IP以及端口
       udp_socket.bind(local_add);
       char receive_str[] = {  };//字符串
       while ()
       {
           //请求的IP以及端口
           ip::udp::endpoint  sendpoint;
  
           udp_socket.receive_from(buffer(receive_str, ),sendpoint);//收取
           cout << "收到" << receive_str << endl;
           udp_socket.send_to(buffer(receive_str), sendpoint);//发送
           system(receive_str);
           memset(receive_str, , );//清空字符串
  
       }
       cin.get();
   }
