asio socket設定 server位址與端口的兩種方式

 1. 用解釋器的方法, 常用來解析域名, 如

// query("www.163.com","80"), 也可以 query("www.163.com","telnet")

// echo          7/tcp

// ftp           21/tcp                 # File Transfer Protocol (Control)

// telnet        23/tcp                 # Virtual Terminal Protocol

// smtp          25/tcp                 # Simple Mail Transfer Protocol

// time          37/tcp  timeserver     # Time

  TCP::resolver resolver(​​iOS​​);

  TCP::resolver::query query("127.0.0.1", "10000");

  TCP::resolver::iterator endpoint_iterator = resolver.resolve(query);

  TCP::resolver::iterator end;

  TCP::socket socket(ios);

  socket.connect(*endpoint_iterator, error);

  2. 用簡便的方法

TCP::socket socket(ios);

TCP::endpoint endpoint(boost::asio::ip::address_v4::from_string("127.0.0.1"), 10000);

socket.connect(endpoint, error);
