示例 1:文件名:index.js

Javascript
// Node.js program to demonstrate the  
// response.connection 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){ 
  
  // Getting connection 
  // by using response.connection Api
  const value = response.connection;
    
  // Display result
  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..."); 
});


Javascript
// Node.js program to demonstrate the  
// response.connection APi
    
// 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
  response.end( "family  : " 
  + value.address().family, 'utf8', () => { 
      console.log("displaying the result..."); 
  
      // Closing the server
      httpServer.close(()=>{
          console.log("server is closed")
      })
  });
}; 
    
// Creating http Server and listing
// on the port 3000
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
