cakephp 4-烘焙新控制器时找不到身份验证组件

Question

我不能使用蛋糕烘烤，相对于身份验证组件有错误。 应用程序使用此组件。 我错过了什么？

这是完整的日志：

谢谢

和AppController.php的第82行，在公共函数initialize（）中

76    $this->loadComponent('Authentication.Authentication',[
77              'requireIdentity'=>true,
78              'logoutRedirect' => '/users/login']);
79
80
81    $this->user=$this->Authentication->getIdentity();
82        $result = $this->Authentication->getResult();
83        if ($result->isValid()) {
84          $identity=$this->Authentication->getIdentity();
85
            ...

烘烤控制器测试时，烘烤将创建相关控制器类的实例，以便检索该控制器的默认模型，它将使用该模型来计算相关夹具，该夹具将被添加到$fixtures中生成的控制器测试用例的属性。

实例化控制器时，将在构造时调用其initialize()方法，这就是问题的出处。您正在通过控制器$this->Authentication->getResult()的方法调用initialize()，导致身份验证组件在连接到控制器的请求对象中查找所需的身份验证数据，并确保不会找到任何此类数据，因为没有进行身份验证。

您应该将调用身份验证组件的逻辑转移到控制器beforeFilter()回调方法中，该方法默认情况下仅在控制器工厂或异常渲染器调用控制器startupProcess()方法时运行，通常是在实际的HTTP请求上下文中，或者是在可以提供可能需要的身份验证数据的单元测试中。
