Node.js http.ServerResponse.setTimeout()用法及代碼示例

httpServerResponse.setTimeout是HTTP模塊中的ServerResponse類的內置應用程序編程接口，用於將Socket的超時值設置為ms(毫秒)。

用法:

const response.setTimeout(msecs[, callback])

參數：此方法以毫秒為單位將第一個參數用作套接字超時值，第二個參數是可選的回調函數。

返回值：此方法隻返回回調函數以進行進一步的操作。

範例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...");  
});

使用以下命令運行index.js文件：

node index.js

輸出：

Server is running at port 3000...
socket is destroyed due to timeout

現在打開瀏覽器並轉到http：//localhost：3000 /，您將看到以下輸出：

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...");  
});

使用以下命令運行index.js文件：

node index.js

輸出：

Server is running at port 3000...
socket is destroyed due to timeout

現在打開瀏覽器並轉到http：//localhost：3000 /，您將看到以下輸出：

ERR_CONNECTION_REFUSED
