记录 SQL 日志

原文地址

1. 在 Listeners 目录新建 QueryListener.php 文件 代码如下：

<?php
namespace App\Listeners;

use Illuminate\Database\Events\QueryExecuted;

class QueryListener
{
    public function handle(QueryExecuted $event)
    {
        if (env('APP_ENV', 'production') == 'local') {
            $sql = str_replace('?', "'%s'", $event->sql);
            $log = vsprintf($sql, $event->bindings);
            $this->put_log('sql', $log);
        }
    }

    private function put_log($file = 'app', $content = '')
    {
        $data = date('Y-m-d');
        $cut_line = str_repeat("-", 100);
        is_dir(storage_path('logs/sql')) or mkdir (storage_path('logs/sql'), 0777, true); // 文件夹不存在则创建
        $content = '[' . date('Y-m-d H:i:s') . "]" . $content;
        @file_put_contents(storage_path('logs/sql/' . $file . '-' . $data . '.log'), $content . "\n" . $cut_line . "\n\n", FILE_APPEND);
    }
}

2. 在 Providers/EventServiceProvider.php 添加如下代码

   <?php
   namespace App\Providers;
   use Laravel\Lumen\Providers\EventServiceProvider as ServiceProvider;
   class EventServiceProvider extends ServiceProvider
   {
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
   
        'Illuminate\Database\Events\QueryExecuted' => [
            'App\Listeners\QueryListener'
        ],
    ];
   }

3. 在 bootstrap/app.php 文件中开启 EventServiceProvider 注册即可

   $app->register(App\Providers\EventServiceProvider::class);

4. 接下来写一个 sql 语句就能在 storage/logs/sql 看到生成的 sql 日志了

    app('db')->where('id', '>', '5')->get();
