YII如何给所有的Controller都设置同一个过滤器,而不是将过滤器的代码复制到一个个的controller?
首先来看代码:
<br>class UserController extends Controller { public function filterIsSessionWrong($filterChain){ if (isset(Yii::app()->user->userId)&&(!empty(Yii::app()->user->userId))) { $filterChain->run(); } else { _echo(2, '用户id获取失败,您需要重新登录'); $this->redirect(array('user/login')); } } public function filters() { return array( 'IsSessionWrong - login,register', ); }
由于客户端是手机。手机访问是通过session来访问的。当这个session不存在的时候,就告诉客户端需要重新登录一下(默认是10天)。
但是我这样做只能在UserController中间(除去注册与登录不需要判断外)去过滤。事实上所有的controller都要检验一下。如果都要检验一下的话,我不得不将这一段代码复制到所有的controller。请问有没有好的方法,将这个判断session的设置为所有的Controller都起作用?

你可以定义一个filter继承自CFilter
,
class SessionCheckFilter extends CFilter { protected function preFilter($filterChain) { if (isset(Yii::app()->user->userId) && (!empty(Yii::app()->user->userId))) { $filterChain->run(); } else { _echo(2, '用户id获取失败,您需要重新登录'); $this->redirect(array('user/login')); } } }
然后在你的controller
中通过 filters
方法使用
class UserController extends Controller { public function filters() { return array( array('application.filters.SessionCheckFilter - edit, create') ); } }

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
