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

httpServerResponse.setTimeout是HTTP模块中的ServerResponse类的内置应用程序编程接口，用于将Socket的超时值设置为ms(毫秒)。

用法:

const response.setTimeout(msecs[, callback])

参数：此方法以毫秒为单位将第一个参数用作套接字超时值，第二个参数是可选的回调函数。

返回值：此方法只返回回调函数以进行进一步的操作。

范例1：Filename-index.js

Javascript

// Node.js program to demonstrate the   
// response.setTimeout() 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) {  
  
  // Setting the socket time out value 
  // by using setTimeout method 
  response.setTimeout(6000,() => { 
    console.log("socket is destroyed due to timeout") 
  }) 
});  
    
// 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...
socket is destroyed due to timeout

现在打开浏览器并转到http：//localhost：3000 /，您将看到以下输出：

ERR_CONNECTION_REFUSED

示例2：Filename-index.js

Javascript

// Node.js program to demonstrate the   
// response.setTimeout() Method 
    
// Importing http module  
var http = require('http');  
  
// Request and response handler  
const httpHandlers = (request, response) => {  
    
  // Setting the socket time out value 
  // by using setTimeout method 
  response.setTimeout(5000,() => { 
    console.log("socket is destroyed due to timeout") 
  }) 
}  
    
// Creating http Server  
var httpServer = http.createServer( 
    httpHandlers).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...
socket is destroyed due to timeout

现在打开浏览器并转到http：//localhost：3000 /，您将看到以下输出：

ERR_CONNECTION_REFUSED
