登录事件的绑定 [ 2.0 版本 ]

1.在web.php文件中的‘user’配置中如下：

'user' => [
    'identityClass' => 'app\models\User',
    'enableAutoLogin' => true,
    'on afterLogin'=>function($event){
        $user=$event->identity;
        $model=new Log_Login();
        $model->USER_ID=$user->USER_ID;
        $model->USER_AGENT=$_SERVER['HTTP_USER_AGENT'];
        $model->IP=$_SERVER['REMOTE_ADDR'];
        $model->LOGIN=date("Y-m-d H:i:s");
        $model->save();
        $_SESSION['log_id']=$model->ID;
    },
    'on beforeLogout'=>function ($event){
        //$user=$event->identity;
        $model = Log_Login::findOne((int)$_SESSION['log_id']);
        $model->LOGOUT=date("Y-m-d H:i:s");
        $model->update();
    }
]
