Real-time logging based on RPC service based on ThinkPHP6 and Swoole

[Introduction]
In today's Internet era, logging is very critical in project development and maintenance a job. As the system continues to develop and grow, the amount of logs will gradually increase. For developers and system maintainers, real-time monitoring and recording of log data becomes particularly important. This article will introduce how to use ThinkPHP6 and Swoole to implement RPC services to achieve real-time logging and reduce the complexity of system troubleshooting.

[Background]
ThinkPHP6 is a lightweight, high-performance PHP development framework that has been widely used in the development of various Web projects. Swoole is a PHP extension for building high-performance, asynchronous, concurrent TCP/UDP/Unix Socket/HTTP/WebSocket services. It provides powerful network protocol and IO resource management capabilities. This article will combine these two tools to build a real-time logging system based on RPC services.

[Technical Solution]

1. First, we need to configure the ThinkPHP6 environment, including installing dependencies, setting up database connections, etc.

2. Next, install the Swoole extension. We can install it through the following command:

   pecl install swoole

3. Create a log processing class, such as LogHandler.php, which is used to implement log recording and distribution. We can write corresponding code in this class for operations such as recording log information to the database and sending it to other systems.

   <?php
   namespace appcommonhandler;
   
   class LogHandler
   {
    public static function addLog($level, $message)
    {
        // 記錄日志的具體邏輯
    }
   }

4. Next, we need to create an RPC server to receive log requests from clients. In ThinkPHP6, you can use the Route class to implement routing. We add a new rpc.php file in the route directory of the project with the following content:

   <?php
   
   use thinkacadeRoute;
   
   Route::group('rpc', function() {
    Route::post('/log', 'rpc/log');
   })->allowCrossDomain();

5. Create a new Rpc.php file in the controller directory (app/controller). This file For the RPC processing class, the code example is as follows:

   <?php
   
   namespace appcontroller;
   
   use appcommonhandlerLogHandler;
   use thinkRequest;
   
   class Rpc
   {
    public function log(Request $request)
    {
        $params = $request->post();
        // 調(diào)用日志處理類中的方法，記錄日志
        LogHandler::addLog($params['level'], $params['message']);
   
        // 返回響應(yīng)給客戶端
        return json([
            'code' => 200,
            'msg' => 'success'
        ]);
    }
   }

6. Finally, we need to initiate an RPC request on the client and send the log information to the server. In the client code, we can send POST requests through CURL or other methods to send log information to the RPC server. The code example is as follows:

   <?php
   
   $url = 'http://your_domain/rpc/log';
   $params = [
    'level' => 'error',
    'message' => 'Something goes wrong!'
   ];
   
   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, $url);
   curl_setopt($ch, CURLOPT_POST, true);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   
   $response = curl_exec($ch);
   curl_close($ch);
   
   $result = json_decode($response, true);
   if ($result['code'] == 200) {
    echo '日志記錄成功';
   } else {
    echo '日志記錄失敗';
   }

[Summary]
By using the combination of ThinkPHP6 and Swoole, we can easily implement a real-time logging system based on RPC services. In the project, we only need to introduce relevant code to easily achieve log recording and distribution. In addition, we can also expand the log processing class and add more functions according to the needs of the project, such as sending logs to the message queue, pushing exception information through WeChat, etc. By recording and monitoring the logs generated by the system in real time, we can discover and solve potential problems faster and improve the efficiency of project development and maintenance.
