laravel添加sql监听

1. 添加listener文件

php artisan make:listener QueryListener

2. 在listener文件中添加执行函数

<?php

namespace App\Listeners;

use Illuminate\Database\Events\QueryExecuted;

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

    /**
     * Handle the event.
     *
     * @param  QueryExecuted  $event
     * @return void
     */
    public function handle(QueryExecuted $event)
    {
        try{
            if (env('APP_DEBUG') == true) { // 如果需要调试
                $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 ] ';
                $logger = fileLogger('sql', 'sql');
                $logger->info($log); // 将sql语句打印到log中
            } 
        }catch (\Exception $e){
            \Log::error('log sql error:'.$e->getMessage());
        }
    }
}

3. 在App\Providers\EventServiceProvider中添加listen

<?php

namespace App\Providers;

use App\Listeners\QueryListener;
use Illuminate\Auth\Events\Registered;
use Illuminate\Auth\Listeners\SendEmailVerificationNotification;
use Illuminate\Database\Events\QueryExecuted;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        Registered::class => [
            SendEmailVerificationNotification::class,
        ],
        QueryExecuted::class => [
            QueryListener::class,
        ]
    ];

    /**
     * Register any events for your application.
     *
     * @return void
     */
    public function boot()
    {
        //
    }
}

5. 配置完成，之后只要设置APP_DEBUG = true就可以打印sql语句到log中了
