Node.js request.socket用法及代碼示例

// Node.js program to demonstrate the  
// req.socket property  
  
// Using require to access http module  
const http = require('http'); 
  
// Requesting from google server 
const req = http.get({ host:'www.geeksforgeeks.org' }); 
  
// Ending the request 
req.end(); 
  
req.once('response', (res) => { 
  
    // Printing socket after getting response 
    console.log(req.socket); 
  
    // Printing address and port after 
    // getting response 
    console.log(`IP address of geeksforgeeks is  
            ${req.socket.localAddress}.`); 
              
    console.log(`Its Port is ${req.socket.localPort}.`); 
});
