Real-time message push based on RPC service of ThinkPHP6 and Swoole

In recent years, with the rapid development of the Internet, real-time communication has become an important requirement for the development of many applications . Real-time message push is one of the most common and popular methods. This article will introduce how to use ThinkPHP6 and Swoole to implement a real-time message push service based on RPC (remote procedure call), and provide specific code examples.

1. Preparation
   Before we start, we need to make sure you have installed the following software:

• PHP 7.2 or above
• Composer (for installing dependencies to create and manage projects)
• Swoole (a high-performance asynchronous concurrency framework based on PHP)
• Redis (an open source in-memory data store)
• Redis extension (used to communicate with the Redis server)
• ThinkPHP6 (an elegant and efficient PHP development framework)

2. Create the project
   First, Open the command line interface and enter your working directory, then execute the following command to create a new ThinkPHP6 project:

composer create-project topthink/think tp6

3. Install Swoole
   Execute the following command in the project root directory To install Swoole:

composer require swoole/swoole

4. Install Redis extension
   Use the following command to install the Redis extension:

pecl install redis

Then add the following lines to your php. ini file:

extension=redis.so

5. Configuring the RPC service
   In the config directory under the root directory of the ThinkPHP6 project, create a new file rpc.php, and add the following code in it:

<?php

return [
    'server' => [
        // 服務監(jiān)聽的IP地址
        'host' => '127.0.0.1',
        // 服務監(jiān)聽的端口號
        'port' => 9501,
        // 異步任務的工作進程數(shù)量
        'task_worker_num' => 4
    ]
];

6. Writing RPC service code
   In the app directory of the ThinkPHP6 project root directory, create a file named push's new controller is used to handle the relevant logic of real-time message push. In this controller, we will use Swoole to create an RPC service and listen on the specified port.

Add the following method in the push controller:

<?php

namespace appcontroller;

use thinkRequest;

class Push
{
    /**
     * RPC服務入口方法
     */
    public function rpcServer(Request $request)
    {
        // 創(chuàng)建一個新的Swoole服務器對象
        $server = new SwooleServer(config('rpc.server.host'), config('rpc.server.port'));
        
        // 設置異步任務的工作進程數(shù)量
        $server->set(array('task_worker_num' => config('rpc.server.task_worker_num')));
        
        // 監(jiān)聽連接事件
        $server->on('connect', function ($server, $fd) {
            echo "客戶端 " . $fd . " 已連接
";
        });
        
        // 監(jiān)聽數(shù)據(jù)接收事件
        $server->on('receive', function ($server, $fd, $from_id, $data) {
            // 處理接收到的數(shù)據(jù)
            $message = json_decode($data, true);
            
            // TODO: 消息推送邏輯
            
            // 發(fā)送響應數(shù)據(jù)
            $server->send($fd, '消息已成功接收');
        });
        
        // 監(jiān)聽關(guān)閉事件
        $server->on('close', function ($server, $fd) {
            echo "客戶端 " . $fd . " 已斷開連接
";
        });
        
        // 啟動RPC服務
        $server->start();
    }
}

7. Start RPC service
   Execute the following command in the command line to start RPC Service:

php think push/rpcServer

8. Client implementation
   In the client code, we can use any tool that supports RPC to communicate with our service. The following is a simple sample code for sending a message to an RPC server:

<?php

/**
 * 向RPC服務發(fā)送消息
 */
function sendMessage($message)
{
    $client = new SwooleClient(SWOOLE_SOCK_TCP);
    
    // 連接到RPC服務端
    if ($client->connect('127.0.0.1', 9501)) {
        // 發(fā)送消息
        $client->send(json_encode($message));
        
        // 接收響應
        echo $client->recv();
        
        // 關(guān)閉連接
        $client->close();
    } else {
        echo "無法連接到RPC服務
";
    }
}

// 調(diào)用sendMessage方法發(fā)送消息
sendMessage(['content' => 'Hello']);

9. Conclusion
   By using ThinkPHP6 and Swoole, we can easily create an RPC-based Real-time message push service. This article provides a simple example, but you can extend and customize it to meet your own needs to meet more complex real-time communication needs. Hope this article is helpful to you!
