Node.js http.server.headersTimeout 方法

http.server.headersTimeout是 HTTP 模块中 Server 类的内置应用程序编程接口，用于获取解析器等待接收完整 HTTP 标头的时间。

句法：

server.headersTimeout

参数：此方法不接受任何参数作为参数。

返回值：此方法返回时间，解析器将等待接收完整的 HTTP 标头。

示例 1：文件名-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...");
});

使用以下命令运行index.js文件：

node index.js

输出：

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

现在在浏览器中运行http://localhost:3000/ ，您将在屏幕上看到以下输出：

hello world

示例 2：文件名-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...");
});

使用以下命令运行index.js文件：

node index.js

输出：

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

现在在浏览器中运行http://localhost:3000/ ，您将在屏幕上看到以下输出：

hello world
