示例1：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// response.end() method 
    
// Importing http module  
var http = require('http');  
    
// Setting up PORT  
const PORT = process.env.PORT || 3000;  
    
// Creating http Server  
var httpServer = http.createServer( 
  function(request, response){  
  
  // Getting connection by using 
  // response.connection method 
  const value = response.connection; 
    
  // Ending the response 
  response.end( "port address:" +  
  value.address().port, 'utf8', () => {  
      console.log("displaying the result...");  
  
      // Closing the server 
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  });  
});  
    
// Listening to http Server  
httpServer.listen(PORT, () => {  
    console.log("Server is running at port 3000...");  
});

执行命令：

node index.js

控制台输出：

Server is running at port 3000...
displaying the result...
displaying the result...
server is closed
server is closed

示例2：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// response.end() method 
    
// Importing http module  
var http = require('http');  
  
// Request and response handler  
const http2Handlers = (request, response) => {  
    
  // Getting connection  
  // by using response.connection Api 
  const value = response.connection; 
    
  // Display result by using end() 
  // api and ending the response 
  response.end( "family :" +  
  value.address().family, 'utf8', () => {  
      console.log("displaying the result...");  
  
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  }); 
  };  
     
// Creating http Server  and listening 
// on the 3000 port 
var httpServer = http.createServer( 
    http2Handlers).listen(3000, () => {  
    console.log("Server is running at port 3000...");  
});

执行命令：

node index.js

控制台输出：

Server is running at port 3000...
displaying the result...
displaying the result...
server is closed
server is closed

浏览器输出：

粘贴localhost地址http：//localhost：3000 /。在浏览器的搜索栏中。

family :IPv6
