Node.js http.server.setTimeout()用法及代码示例

http.server.setTimeout()是HTTP模块中Server类的内置应用程序编程接口，用于设置套接字的超时值。

用法:

server.setTimeout([msecs][, callback])

参数：此方法以毫秒为单位获取套接字超时值。

返回值：此方法只返回回调函数以进行进一步操作。

示例1：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// server.setTimeout() 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...");  
  });  
});  
    
// Listening to http Server  
// by using listen() api 
httpServer.listen(PORT, () => {  
    console.log( 
    "Server is running at port 3000...");  
}); 
  
httpServer.setTimeout(3000,()=>{ 
  
  console.log( 
    "Socket is destroyed due to timeout") 
  
    // Closing server  
    // by using close() api 
    httpServer.close(()=>{ 
        console.log("Server is closed") 
    }) 
})

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...
Socket is destroyed due to timeout
Socket is destroyed due to timeout
Server is closed
Server is closed

浏览器输出：在浏览器的搜索栏中粘贴本地主机地址http：//localhost：3000 /。

socket buffersize:0

示例2：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// server.setTimeout() 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...");  
  }); 
  };  
    
// Listening to http Server  
// by using listen() api 
var httpServer = http.createServer( 
    http2Handlers).listen(3000, () => {  
    console.log("Server is running at port 3000...");  
});  
  
httpServer.setTimeout(3000,()=>{ 
    console.log( 
    "Socket is destroyed due to timeout") 
    
      // Closing server  
      // by using close() api 
      httpServer.close(()=>{ 
          console.log("Server is closed") 
      }) 
    })

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...
Socket is destroyed due to timeout
Socket is destroyed due to timeout
Server is closed
Server is closed

浏览器输出：在浏览器的搜索栏中粘贴本地主机地址http：//localhost：3000 /。

socket local address:::1
