本文主要给大家介绍的是关于Laravel给生产环境添加监听事件(SQL日志监听)的相关内容,分享出来供大家参考学习,下面来一起看看详细的介绍:
laravel版本:5.2.*
一、创建监听器
php artisan make:listener QueryListener --event=Illuminate\Database\Events\QueryExecuted
or
sudo /usr/local/bin/php artisan make:listener QueryListener --event=Illuminate\Database\Events\QueryExecuted
会自动生成文件 app/Listeners/QueryListener.php
二、注册事件
打开 app/Providers/EventServiceProvider.php,在 $listen 中添加 IlluminateDatabaseEventsQueryExecuted 事件的监听器为 QueryListener
protected $listen = [ 'IlluminateDatabaseEventsQueryExecuted' => [ 'AppListenersQueryListener', ], ];
最终代码如下
namespace AppProviders; use IlluminateContractsEventsDispatcher as DispatcherContract; use IlluminateFoundationSupportProvidersEventServiceProvider as ServiceProvider; class EventServiceProvider extends ServiceProvider { /** * The event listener mappings for the application. * * @var array */ protected $listen = [ 'AppEventsSomeEvent' => [ 'AppListenersEventListener', ], 'IlluminateDatabaseEventsQueryExecuted' => [ 'AppListenersQueryListener', ], ]; /** * Register any other events for your application. * * @param IlluminateContractsEventsDispatcher $events * @return void */ public function boot(DispatcherContract $events) { parent::boot($events); // } }
三、添加逻辑
打开 app/Listeners/QueryListener.php
光有一个空的监听器是不够的,我们需要自己实现如何把 $sql 记录到日志中。为此,对 QueryListener 进行改造,完善其 handle 方法如下:
$sql = str_replace("?", "'%s'", $event->sql); $log = vsprintf($sql, $event->bindings); Log::info($log);
最终代码如下
namespace AppListeners; use Log; use IlluminateDatabaseEventsQueryExecuted; use IlluminateQueueInteractsWithQueue; use IlluminateContractsQueueShouldQueue; 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, $event->bindings); Log::info($log); } }
