Node.js http.ClientRequest request.socket用法及代码示例

request.socket

• <stream.Duplex>

对底层套接字的引用。通常用户不想访问此属性。特别是，由于协议解析器附加到套接字的方式，套接字不会发出 'readable' 事件。

const http = require('node:http');
const options = {
  host: 'www.google.com',
};
const req = http.get(options);
req.end();
req.once('response', (res) => {
  const ip = req.socket.localAddress;
  const port = req.socket.localPort;
  console.log(`Your IP address is ${ip} and your source port is ${port}.`);
  // Consume response object
});

此属性保证是 <net.Socket> 类的实例，它是 <stream.Duplex> 的子类，除非用户指定了 <net.Socket> 以外的套接字类型。
