类 AppHttpControllersPostController 不存在

I have created a controller called PostController. This is a controller for my blog. When I navigate to my blog i get the following error Class AppHttpControllersPostController does not exist even though it does exist. The controller is called PostController.php. Here is what the route looks like Route::get('blog','PostController@index');. I have read that running some composer commands will help but none of them have helped me. composer dumpautoload as well as composer update. Am i missing some step here? Anyone run into a similar problem? Please let me know if additional information is needed.

编辑这是顶部的命名空间.

use AppHttpControllers;
use AppPosts;
use AppUser;
use AppHttpControllersController;
use AppHttpRequestsPostFormRequest;
use IlluminateHttpRequest;

这是整个控制器.

谢谢.

推荐答案

如果 composer dumpautoload 没有帮助，请检查 PostController 中是否有正确的 namespace 声明.php 并仔细检查类名/路由声明中的拼写错误.

"autoload": {
    "psr-4": {
        "App\": "app/"
    }
},

Route::get('blog',PostController::class . '@index');

Route::get('blog',AppHttpControllersPostController::class . '@index');

namespace AppHttpControllers;
