How to use Hyperf framework for message push

How to use the Hyperf framework for message push

With the development of the Internet, real-time message push has become more and more important in many application scenarios. As a high-performance PHP microservice framework, the Hyperf framework has the characteristics of lightweight, low latency and high concurrency, and is very suitable for real-time message push. This article will introduce how to implement message push in the Hyperf framework and provide specific code examples.

1. Install the Hyperf framework

First, we need to install the Hyperf framework. It can be installed through the composer command:

composer create-project hyperf/hyperf-skeleton

2. Install the Swoole extension

The underlying layer of the Hyperf framework uses the Swoole extension, so we need to install the Swoole extension first. You can install it through the following command:

pecl install swoole

3. Create a WebSocket server

In the Hyperf framework, you can use the WebSocket server to implement real-time message push. We need to create a WebSocket controller to handle client connections and messages.

First, create a AppControllerWebSocketController file and write the following code:

<?php

declare(strict_types=1);

namespace AppController;

use HyperfWebSocketServerContext;
use HyperfWebSocketServerSender;

class WebSocketController
{
    public function onConnect($fd)
    {
        // 当客户端连接时触发
    }

    public function onMessage($fd, $data)
    {
        // 当接收到客户端消息时触发
        $sender = make(Sender::class);
        $sender->push($fd, 'Hello, ' . $data);
    }

    public function onClose($fd)
    {
        // 当客户端断开连接时触发
    }
}

Then, modify the config/autoload/server.php file and add WebSocket Server configuration:

<?php

declare(strict_types=1);

return [
    'servers' => [
        [
            'name' => 'websocket',
            'type' => Server::TYPE_WEB_SOCKET,
            'host' => '0.0.0.0',
            'port' => 9502,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_HAND_SHAKE => [HyperfWebSocketServerListenerHandShakeListener::class, 'onHandShake'],
                Event::ON_MESSAGE => [AppControllerWebSocketController::class, 'onMessage'],
                Event::ON_CLOSE => [AppControllerWebSocketController::class, 'onClose'],
            ],
        ],
    ],
];

4. Write the front-end page

Next, we need to write a front-end page to test the WebSocket server. Create a index.html file in the public directory and write the following code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>WebSocket Demo</title>
</head>
<body>
    <input type="text" id="message" placeholder="请输入消息">
    <button onclick="sendMessage()">发送</button>

    <script>
        var ws = new WebSocket("ws://localhost:9502");

        ws.onopen = function() {
            console.log("连接成功");
        };

        ws.onmessage = function(evt) {
            console.log("收到消息:" + evt.data);
        };

        function sendMessage() {
            var message = document.getElementById("message").value;
            ws.send(message);
        };
    </script>
</body>
</html>

5. Start the WebSocket server

Finally, we need to start WebSocket server, allowing it to listen for client connections and messages. Execute the following command in the terminal:

php bin/hyperf.php start

So far, we have completed a simple message push function implemented using the Hyperf framework. When we visit the http://localhost/index.html page, a connection to the WebSocket server will be established. Then we enter the message and click the send button, and we can see the received message in the console.

It should be noted that this article only provides a simple example to demonstrate how to use WebSocket in the Hyperf framework for real-time message push. There may be more complex requirements in actual applications, which require corresponding expansion and optimization according to specific scenarios.
