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sqlmake:listener QueryListener --event=Illuminate/Database/Events/QueryExecuted
2、监听器类代码
./app/Listeners/QueryListener.php
<?phpnamespace 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,希望本文所述对大家基于Laravel框架的PHP程序设计有所帮助。
