Workerman Development: How to implement a Web server based on the HTTP protocol, specific code examples are required
Introduction:
With the rapid development of the Internet, Web development has become more and more important. The basis for providing Web services is the Web server. Workerman is a high-performance PHP development framework that can not only develop network communication servers, but also implement web servers based on the HTTP protocol. This article will introduce the development of a simple HTTP web server using Workerman and provide specific code examples.
1. Overview of Workerman:
1.1 What is Workerman?
Workerman is a multi-process asynchronous network communication framework developed in PHP. It implements network communication of TCP/UDP protocol in an event-driven manner. Workerman has the characteristics of high performance and high concurrency, and is mainly used to develop network applications such as real-time message push, instant chat, mobile communications, and game servers.
1.2 Features of Workerman:
- High performance: Workerman uses a pure PHP asynchronous network IO framework, which is very suitable for high-concurrency network communication.
- Lightweight: Workerman’s core library is very streamlined and can be used for secondary development quickly and flexibly.
- Cross-platform: Workerman is suitable for Linux, Unix, Mac OS and other platforms, and also supports Windows systems.
- Support multiple processes: Workerman can automatically create and destroy processes according to the system's resource conditions, making full use of server resources.
- Based on event-driven: Workerman adopts the event polling model to implement network applications through event callback functions to improve performance and stability.
2. Implementation steps of Web server based on HTTP protocol:
2.1 Environment preparation:
Before you start, make sure you have successfully installed the PHP environment and installed the Workerman framework.
2.2 Create the folder structure:
Create a new folder in which we will store the relevant code files. The folder structure is as follows:
-
web-server (folder)
- index.php
- start.php
- Workerman (Workerman Framework)
2.3 Write the index.php file:
The index.php file is the entry file of the Web server and is mainly responsible for processing HTTP requests and responses.
<?php
use WorkermanWorker;
require_once __DIR__ . '/Workerman/Autoloader.php';
$http_worker = new Worker("http://0.0.0.0:8080");
$http_worker->count = 4;
$http_worker->onMessage = function($connection, $data)
{
// 構(gòu)造HTTP響應(yīng)頭
$http_response = "HTTP/1.1 200 OK
Content-Type: text/html;charset=utf-8
Hello Workerman!";
// 發(fā)送HTTP響應(yīng)給客戶端
$connection->send($http_response);
};
Worker::runAll();
?>2.4 Write the start.php file: The
start.php file is mainly used to start the Web server and listen to the port.
<?php
require_once __DIR__ . '/Workerman/Autoloader.php';
use WorkermanWorker;
// 創(chuàng)建一個Worker監(jiān)聽端口8080，使用http協(xié)議通訊
$http_worker = new Worker("http://0.0.0.0:8080");
// 設(shè)置Web服務(wù)器的進(jìn)程數(shù)
$http_worker->count = 4;
// 當(dāng)客戶端發(fā)來消息時的回調(diào)函數(shù)
$http_worker->onMessage = function($connection, $data)
{
// 構(gòu)造HTTP響應(yīng)頭
$http_response = "HTTP/1.1 200 OK
Content-Type: text/html;charset=utf-8
Hello Workerman!";
// 發(fā)送HTTP響應(yīng)給客戶端
$connection->send($http_response);
};
// 啟動Web服務(wù)器
Worker::runAll();
?>3. Run the Web server:
3.1 Use the command line to enter the directory where the web-server is located.
3.2 Execute the command to start the web server: php start.php start
3.3 Open the browser and enter http://localhost:8080 in the address bar, you will see the page showing "Hello Workerman" !", indicating that the web server is running normally.
Conclusion:
Through the introduction and code examples of this article, we have learned how to use Workerman to develop a simple web server based on the HTTP protocol. With its high performance and high concurrency, Workerman has become an important tool in PHP development and can meet the needs of various network applications. I hope this article can be helpful to you. If you are interested in more in-depth applications of Workerman, you can refer to the official Workerman documentation to learn and explore.
