Request::instance() : $request;// 控制器初始化$this->_initialize();//<--代码位置 -->if (!defined('IMG_PRE')) {define("IMG_PRE", $this->request->domain());//定义获取域名常量
//            define("IMG_PRE", 'https://yunlingshidai.oss-cn-shanghai.aliyuncs.com');//也可以是云端域名}//<--代码位置 -->// 前置操作方法if ($this->beforeActionList) {foreach ($this->beforeActionList as $method => $options) {is_numeric($method) ?$this->beforeAction($options) :$this->beforeAction($method, $options);}}}
