我对 cakephp ver3.1.3 没有经验
我按照说明实现了登录认证功能； http://book.cakephp.org/3.0/en/tutorials-and-examples/blog-auth-example/auth.html
我成功地烘焙了我的 cakephp v3.1.3 应用程序。
我对 UsersController.php 有疑问
我从 http://book.cakephp.org/3.0/en/tutorials-and-examples/blog-auth-example/auth.html 复制并粘贴了以下代码;
public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
// Allow users to register and logout.
// You should not add the "login" action to allow list. Doing so would
// cause problems with normal functioning of AuthComponent.
$this->Auth->allow(['add', 'logout']);
} //public function beforeFilter(Event $event)
此代码的存在导致以下错误；
Strict (2048): Declaration of App\Controller\UsersController::beforeFilter() should be compatible with App\Controller\AppController::beforeFilter(Cake\Event\Event $event) [APP/Controller\UsersController.php, line 12] Code Context include - APP/Controller\UsersController.php, line 12 Composer\Autoload\includeFile - ROOT\vendor\composer\ClassLoader.php, line 412 Composer\Autoload\ClassLoader::loadClass() - ROOT\vendor\composer\ClassLoader.php, line 301 spl_autoload_call - [internal], line ?? class_exists - [internal], line ??

如果我删除有问题的代码段，错误就会消失。代码段有什么问题？
最佳答案
解决方案是在 UsersController.php 中添加以下行
use Cake\Event\Event;
蛋糕烘焙版没有上面这行
关于php - UsersController::beforeFilter() 的声明应该与 AppController::beforeFilter(Cake\Event\Event $event) 兼容，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32690756/
