这篇文章主要介绍了Laravel框架实现利用监听器进行sql语句记录功能,结合实例形式分析了Laravel框架监听器的创建、引入以及使用监听器记录sql语句的相关操作技巧,需要的朋友可以参考下
本文实例讲述了Laravel框架实现利用监听器进行sql语句记录功能。分享给大家供大家参考,具体如下:
利用监听器进行sql语句记录
1、监听sql语句的事件类已经定义,直接创建监听器类即可:
# 监听sql make:listener QueryListener --event=Illuminate\Database\Events\QueryExecuted
2、监听器类代码
./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, $event->bindings); # 此处$uid定义是依赖于中间件记录操作日志代码 $uid = isset($_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、引入监听器
./app/Providers/EventServiceProvider.php
protected $listen = [ ... \Illuminate\Database\Events\QueryExecuted::class => [ 'App\Listeners\QueryListener' ], ... ];
此时进行操作时就会记录sql日志
