7.boostUDP通信

• 客戶端

  #include <iostream>
  #include<string>
  #include <boost/asio.hpp>
  #include <stdlib.h>
  using namespace std;
  using namespace boost::asio;
  
  
  void main()
  {
      //一個服務的類，給這個UDP通信初始化
      io_service io_serviceA;
      //通過服務給這個UDP通信初始化
      ip::udp::socket udp_socket(io_serviceA);
      //設置連接的IP還有端口
      ip::udp::endpoint local_add(ip::address::from_string("127.0.0.1"), 1080);
      //添加協議
      udp_socket.open(local_add.protocol());
      char receive_str[1024] = { 0 };//字符串
  
      while (1)
      {
          string sendstr;
          cout << "請輸入";
          cin >> sendstr;
          cout << endl;
          udp_socket.send_to(buffer(sendstr.c_str(), sendstr.size()), local_add);
          udp_socket.receive_from(buffer(receive_str, 1024), local_add);
          cout << "收到" << receive_str << endl;
      }
  
      system("pause");
  }
