Laravel框架实现利用监听器进行sql语句记录功能 悠悠 2023-06-23 15:22 2阅读 0赞 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
