【问题描述】：
让我先说“我知道这个问题经常被问到”。当我说对我没有任何帮助时，请相信我。
我创建了一个名为PostController 的控制器。这是我博客的控制器。当我导航到我的博客时，我收到以下错误Class App\Http\Controllers\PostController does not exist，即使它确实存在。控制器称为PostController.php。这是路线的样子Route::get('blog','PostController@index');。我读过运行一些composer 命令会有所帮助，但它们都没有帮助我。 composer dumpautoload 和 composer update。我在这里错过了一些步骤吗？有人遇到类似的问题吗？如果需要更多信息，请告诉我。
编辑 这是顶部的命名空间。
use App\Http\Controllers;
use App\Posts;
use App\User;
use App\Http\Controllers\Controller;
use App\Http\Requests\PostFormRequest;
use Illuminate\Http\Request;
这是整个控制器。
