cakephp 4 - 烘焙新控制器时未找到身份验证组件

Question

我不能使用蛋糕烘焙，我有一个与身份验证组件相关的错误。该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public函数initialize()

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
            ...

当烘焙控制器测试时，烘焙将创建相关控制器的实例class以检索该控制器的默认模型，它使用该模型来绘制相关的夹具，该夹具被添加到生成的控制器测试用例的 $fixtures 属性。

当实例化一个控制器时，它的 initialize() 方法将在构建时被调用，这就是问题开始的地方。您在控制器 initialize() 方法中调用 $this->Authentication->getResult()，导致身份验证组件在附加到控制器的请求对象中查找所需的身份验证数据，果然它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移动到控制器 beforeFilter() 回调方法中，默认情况下，此方法仅运行当控制器工厂或异常渲染器调用控制器时 startupProcess() 方法，通常在实际的 HTTP 请求上下文中，或者在可以提供可能需要的身份验证数据的单元测试上下文中。
