返回值：此属性返回充当 net.Socket 的代理对象。

示例 1：文件名：index.js

Javascript

// Node.js program to demonstrate the  
// request.socket property
    
// 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 proxy socket 
  // by using request.socket
  const value = request.socket;
    
  // Display result
  response.end( value.remoteFamily, 'utf8', () => { 
    console.log("Writing remotefamily of socket..."); 
  
    httpServer.close(() => {
      console.log("server is closed")
    })
  }); 
}); 
    
// 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

输出：

Server is running at port 3000...

现在打开浏览器并转到http://localhost:3000/ ， 您将在屏幕上看到以下输出：

IPv6

现在关闭浏览器，您将在终端屏幕上看到以下输出：

Server is running at port 3000...
Writing remotefamily of socket...
server is closed

示例 2：文件名：index.js

Javascript

// Node.js program to demonstrate the  
// request.socket property
    
// Importing http module 
var http = require('http'); 
  
// Request and response handler 
const http2Handlers = (request, response) => { 
    
  // Getting proxy socket 
  // by using request.socket method
  const value = request.socket;
    
  // Display result
  response.end( value.remoteFamily, 'utf8', () => { 
    console.log("Writing remotefamily of socket..."); 
  
    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..."); 
});

使用以下命令运行index.js文件：

node index.js

输出：

Server is running at port 3000...

现在打开浏览器并转到http://localhost:3000/ ， 您将在屏幕上看到以下输出：

IPv6

现在关闭浏览器，您将在终端屏幕上看到以下输出：

Server is running at port 3000...
Writing remotefamily of socket...
server is closed
