Thinkphp5框架简单实现钩子(Hook)行为的方法示例

<?php
namespace app\api\behavior;
//行为类
class AopTest{
  //绑定api初始化
  public function apiInit(&$params){
   //参数获取
   $id = input('id');//获取请求参数
   $uid = session('UID');//获取session 登录uid
   //打印输出
   echo PHP_EOL;
   echo 'ip检查'.$params.' GET:'.$id;
   echo ' uid='.$uid;
   echo PHP_EOL;
   //获取当前模块 控制器名 方法名称
   $request= \think\Request::instance();
   $controller_name = $request->controller();
   $model_name = $request->module();
   $action_name = $request->action();
   echo ' controller_name='.$controller_name.' model_name='.$model_name.' action_name='.$action_name;
   //构建数组
   $data = array();
   $data['status'] = 0;
   $data['msg'] = '没有权限';
   //exit(json_encode($data));//以json格式返回数据
  }
  //绑定api结束
  public function apiEnd(&$params){
   echo PHP_EOL;
   echo '日志记录'.$params;
   echo PHP_EOL;
  }
}

// 应用行为扩展定义文件
return [
 //接口初始化
 'api_init'  => ['app\\api\\behavior\\AopTest'],
 'api_end'  => ['app\\api\\behavior\\AopTest'],
];

<?php
namespace app\api\controller;
use \think\Hook;
class Index
{
  //访问url http://app.tp5.com/index.php/api/index/index?id=5
 public function index()
 {
  session_start();
  session('UID',123);
  $id = input('id');
  $params1 = '参数1';
  $res = Hook::listen('api_init',$params1);
  echo var_export($res, true);
  echo 'api index';
  $params2 = '参数2';
  Hook::listen('api_end',$params2);
 }
}
