// 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){  
  
  
  response.writeHead(200, { 
    'Content-Length':Buffer.byteLength("GeeksforGeeks"), 
    'Content-Type':'text/plain'
  }) 
  
  // Getting the statusMessage  
  // by using statusMessage API 
  const value = response.statusMessage; 
    
  // Display result 
  // by using end() api 
  response.end( "hello World", 'utf8', () => {  
      console.log("displaying the result...");  
  
  
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  });  
  
  console.log("status message:" + value) 
});  
    
// Listening to http Server  
httpServer.listen(PORT, () => {  
    console.log("Server is running at port 3000...");  
});

使用以下命令運行index.js文件：

node index.js

控製台輸出：

Server is running at port 3000...
status message:OK
displaying the result...
server is closed

示例2：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// response.statusMessage APi 
    
// Importing http module  
var http = require('http');  
  
// Request and response handler  
const http2Handlers = (request, response) => {  
    
    response.writeHead(200, { 
       'Content-Type':'text/plain'
      }).end( "hello World", 'utf8', () => {  
        console.log("displaying the result...");  
    });  
      
      // Getting the statusMessage  
      // by using statusMessage API 
      const value = response.statusMessage; 
  
      httpServer.close(()=>{ 
        console.log("server is closed") 
    }) 
      
    console.log("status message:" + value) 
  };  
    
// Creating http Server  
var httpServer = http.createServer( 
    http2Handlers).listen(3000, () => {  
    console.log("Server is running at port 3000...");  
});
