Node.js http.ServerResponse.setTimeout() 方法

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 的超时值设置为毫秒（毫秒） 。

句法：

const response.setTimeout(msecs[, callback])

参数：该方法将第一个参数作为套接字超时值，以毫秒为单位，第二个参数是一个可选的回调函数。

返回值：此方法只返回一个回调函数以供进一步操作。

示例 1：文件名-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：文件名-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
