Node.js http.server.headersTimeout用法及代碼示例

http.server.headersTimeout是HTTP模塊中Server類的內置應用程序編程接口，用於獲取解析器等待接收完整HTTP標頭的時間。

用法:

server.headersTimeout

參數：此方法不接受任何參數作為參數。

返回值：此方法返回時間，解析器將等待接收完整的HTTP標頭。

範例1：Filename-index.js

Javascript

// Node.js program to demonstrate the   
// server.headersTimeout 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) { 
  
    // Display result by using end() method 
    response.end("hello world", 'utf8', () => { 
        console.log("displaying the result..."); 
  
        const value = httpServer.headersTimeout; 
        console.log("header time out value:" + value) 
  
        // Closing server by using close() method 
        httpServer.close(() => { 
            console.log("server is closed") 
        }) 
    }); 
}); 
  
// Listening to http Server  
httpServer.listen(PORT, () => { 
    console.log("Server is running at port 3000..."); 
});

使用以下命令運行index.js文件：

node index.js

輸出：

Server is running at port 3000...
displaying the result...
header time out value:60000
server is closed

現在在瀏覽器中運行http：//localhost：3000 /，您將在屏幕上看到以下輸出：

hello world

示例2：Filename-index.js

Javascript

// Node.js program to demonstrate the   
// server.headersTimeout method 
  
// Importing http module  
var http = require('http'); 
  
// Request and response handler  
const http2Handlers = (request, response) => { 
  
    // Display result 
    // by using end() method 
    response.end("hello world", 'utf8', () => { 
        console.log("displaying the result..."); 
  
        const value = httpServer.headersTimeout; 
        console.log("header time out value:" + value) 
  
        // Closing server  
        // by using close() method 
        httpServer.close(() => { 
            console.log("server is closed") 
        }) 
    }); 
}; 
  
// Creating http Server  
var httpServer = http.createServer( 
    http2Handlers).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...
displaying the result...
header time out value:60000
server is closed

現在在瀏覽器中運行http：//localhost：3000 /，您將在屏幕上看到以下輸出：

hello world
