      boost::asio::io_service io_service;

tcp::resolver resolver(io_service);
tcp::resolver::query query(tcp::v4(), argv[
    
      1
    
      ], 
    
      "
    
      daytime
    
      "
    
      );
tcp::resolver::iterator endpoint_iterator 
    
      =
    
       resolver.resolve(query);
tcp::resolver::iterator end;

tcp::socket socket(io_service);
boost::system::error_code error 
    
      =
    
       boost::asio::error::host_not_found;

    
      while
    
       (error 
    
      &&
    
       endpoint_iterator 
    
      !=
    
       end)
{
 std::cout 
    
      <<
    
       (
    
      *
    
      endpoint_iterator).endpoint() 
    
      <<
    
       std::endl;
 socket.close();
 socket.connect(
    
      *
    
      endpoint_iterator
    
      ++
    
      , error);
}

   
     

 

客户端连接指定地址

  
    

   
     
   
     boost::asio::ip::tcp::socket socket(io_service);
boost::asio::ip::tcp::endpoint endpoint(
 boost::asio::ip::address::from_string(
   
     "
   
     1.2.3.4
   
     "
   
     ), 
   
     12345
   
     );
socket.connect(endpoint);
  
    

 

服务端侦听端口

  
    

   
     
   
     boost::asio::io_service io_service;
tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), 
   
     13
   
     ));


   
     for
   
      (;;)
{
 tcp::socket socket(io_service);
 acceptor.accept(socket);

}
