Javascript

// Node.js program to demonstrate the  
// request.method 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 request method 
  // by using request.method method
  const value = request.method;
    
  // Display result on the console
  response.end( "method : " + value, '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..."); 
});

Javascript

// Node.js program to demonstrate the  
// request.method Method
    
// Importing http module 
var http = require('http'); 
  
// Request and response handler function
const http2Handlers = (request, response) => { 
    
  // Getting request method 
  // by using request.method Api
  const value = request.method;
    
  // Display result
  response.end( "method : " + value , 'utf8', () => { 
      console.log("displaying the result..."); 
  
      // Closing the server
      httpServer.close(()=>{
          console.log("server is closed")
      })
  });
}; 
    
// Creating http Server and listening 
// on the given port number
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：将本地主机地址 http://localhost:3000/ 粘贴到浏览器的搜索栏中。
