利用監聽器進行sql語句記錄

1、監聽sql語句的事件類已經定義，直接建立監聽器類即可：

# 監聽sql
make:listener QueryListener --event=Illuminate\Database\Events\QueryExecuted

2、監聽器類程式碼

./app/Listeners/QueryListener.php

<?php

namespace App\Listeners;

use Illuminate\Database\Events\QueryExecuted;
use Illuminate\Queue\InteractsWithQueue
 
;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\Http\Models\OperationLog;

class QueryListener
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  QueryExecuted  $event
     * @return
 
 void
     */
    public function handle(QueryExecuted $event)
    {
        $sql = str_replace("?", "'%s'", $event->sql);
        $log = vsprintf($sql, $event->bindings);
        # 此處$uid定義是依賴於中介軟體記錄操作日誌程式碼
        $uid = isset($_SERVER['admin_uid']) ? $_SERVER['admin_uid'] : 0;
        if('select'
 
 != substr($log , 0 , 6)){
            if('insert into `operationLog`' != substr($log , 0 , 26)){
                $OperationLog = new OperationLog();
                $OperationLog->uid = $uid;
                $OperationLog->sql = $log;
                $OperationLog->input = '';
                $OperationLog->save();
            }
        }
    }
}

3、引入監聽器

./app/Providers/EventServiceProvider.php

protected $listen = [
        ...
        \Illuminate\Database\Events\QueryExecuted::class => [
            'App\Listeners\QueryListener'
        ],
        ...
    ];

此時進行操作時就會記錄sql日誌
