Javascript

// Node.js program to demonstrate the  
// request.complete 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){ 
  
  // Checking if message is parsed or not
  // by using request.complete Api
  const value = request.complete;
    
  // Display result
  response.end( "message has been sent : " 
      + value, 'utf8', () => { 
      console.log("displaying the result..."); 
  
      httpServer.close(()=>{
          console.log("server is closed")
      })
  }); 
}); 
    
// Listening to http Server 
httpServer.listen(PORT, () => { 
    console.log("Server is running at port 3000..."); 
});

输出：

输出：控制台内

// Importing http module 
var http = require('http'); 
  
// Request and response handler 
const http2Handlers = (request, response) => { 
    
  // Checking if message is parsed or not
  // by using request.complete Api

      + value, 'utf8', () => { 
      console.log("displaying the result..."); 
  
      httpServer.close(()=>{
          console.log("server is closed")
      })
  });
  }; 
    
// Creating http Server 
var httpServer = http.createServer(
    http2Handlers).listen(3000, () => { 
    console.log("Server is running at port 3000...");
