示例 1：文件名：index.js

Javascript

// Node.js program to demonstrate the  
// response.statusMessage APi
    
// 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..."); 
});

使用以下命令运行index.js文件：

node index.js

控制台输出：

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

示例 2：文件名：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..."); 
});

使用以下命令运行index.js文件：

node index.js

控制台输出：

Server is running at port 3000...
