Node.js http.ServerResponse.socket用法及代码示例

httpServerResponse.socket 是 http 模块中 ServerResponse 类的内置应用程序编程接口，用于获取底层套接字对象的引用。

用法:

response.socket

参数：此方法不接受任何参数作为参数。

返回值:此方法返回底层套接字对象的引用。

示例1：Filename：index.js

Javascript


// Node.js program to demonstrate the  
// response.socket 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 the reference of the 
  // underlying socket object
  // by using socket API
  const value = response.socket;
  
    
  // display result
  // by using end() api
  response.end( "socket buffersize:" 
      + value.bufferSize, '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..."); 
});

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...
displaying the result...
displaying the result...
server is closed
server is closed

浏览器输出：

粘贴localhost地址http：//localhost：3000 /。在浏览器的搜索栏中。

socket buffersize:0

示例2：Filename：index.js

Javascript


// Node.js program to demonstrate the  
// response.socket APi
    
// Importing http module 
var http = require('http'); 
  
// Request and response handler 
const http2Handlers = (request, response) => { 
    
  // Getting the reference of the underlying socket object
  // by using socket API
  const value = response.socket;
    
  // Display result
  // by using end() api
  response.end( "Socket local address:" 
      + value.localAddress, 'utf8', () => { 
      console.log("displaying the result..."); 
  
      // Closing the server
      httpServer.close(()=>{
          console.log("server is closed")
      })
  });
  }; 
    
// Creating http Server and listening
// on the given port 
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...
displaying the result...
displaying the result...
server is closed
server is closed

浏览器输出：

粘贴localhost地址http：//localhost：3000 /。在浏览器的搜索栏中。

socket local address:::1
