Laravel sql 日志记录

1. 在　app／Providers/EventServicePorvider.php 文件中 添加要注册的事件

   use Illuminate\Database\Events\QueryExecuted;
   use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
   class EventServiceProvider extends ServiceProvider
   {
       protected $listen = [
           'Illuminate\Database\Events\QueryExecuted' => [
               'App\Listeners\QueryListener',
           ],
       ];
   }

2. 执行 命令 php artisan event:generate

3. 在 App\Listeners\QueryListener 文件的 handle方法中编写记录sql的业务逻辑，如：

   public function handle(QueryExecuted $event)
   {
       try{
           if (env('APP_DEBUG') == true) {
               $sql = str_replace("?", "'%s'", $event->sql);
               foreach ($event->bindings as $i => $binding) {
                   if ($binding instanceof DateTime) {
                       $event->bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
                   } else {
                       if (is_string($binding)) {
                           $event->bindings[$i] = "'$binding'";
                       }
                   }
               }
               $log = vsprintf($sql, $event->bindings);
               $log = $log.'  [ RunTime:'.$event->time.'ms ] ';
               (new Logger('sql'))->pushHandler(new RotatingFileHandler(storage_path('logs/sql/sql.log')))->info($log);
           }
       }catch (Exception $exception){
   
       }
   }

日志文件默认保存在 storage/logs/sql/ 目录下
