让我先说我知道这个问题经常被问到."当我说没有任何效果时，请相信我.
Let me just start by saying "I know this question gets asked a lot." believe me when i say nothing has worked for me.
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 AppHttpControllersPostController does not exist 即使它确实存在.控制器名为 PostController.php.下面是路由的样子 Route::get('blog','PostController@index');.我读到运行一些 composer 命令会有所帮助，但没有一个对我有帮助.composer dumpautoload 以及 composer update.我在这里错过了一些步骤吗?有人遇到过类似的问题吗?如果需要其他信息，请告诉我.
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.

谢谢.
如果 composer dumpautoload 没有帮助，请检查 PostController 中是否有正确的 并仔细检查类名/路由声明中的拼写错误.namespace 声明.php
If composer dumpautoload is not helping then check if you have proper namespace declaration in PostController.php and double check for typos in class name/route declaration.
如果失败，请检查 composer.json 的自动加载配置，它应该是这样的:
If this fails check composer.json for autoload configuration, it should have something like this:
"autoload": {
"psr-4": {
"App\": "app/"
}
},
作为旁注，您可以使用以下内容:
As a side note you could use something like this:
Route::get('blog',PostController::class . '@index');
或
Route::get('blog',AppHttpControllersPostController::class . '@index');
有了这个，任何体面的 IDE 都应该在找不到文件/有拼写错误时发出某种警告
With this any decent IDE should give some kind of a warning if it can't find the file/there's a typo
编辑:
你的文件应该有这样一行
Your file should have a line like this
namespace AppHttpControllers;
在文件的开头，在 <?php 或 <?php declare(strict_types = 1); 之后，如果您使用的是 php7 严格模式
At the beggining of the file, right after <?php or <?php declare(strict_types = 1); if you're using php7 strict mode
