PSR-4 autoloading not working
提问by SUB0DH
I have created an app/modulesdirectory and autoloaded it using PSR-4 like this:
我创建了一个app/modules目录并使用 PSR-4 自动加载它，如下所示：
"psr-4": {
"Modules\": "app/modules"
}
And I also did composer dumpautoload. I have the following directory structure:
我也这样做了composer dumpautoload。我有以下目录结构：
app
- ...
- modules
-- ModuleName
--- controllers
---- BackendController.php
...
The file BackendController.phphas the namespace Modules\ModuleName\Controllers.
该文件BackendController.php具有命名空间Modules\ModuleName\Controllers。
And in routes.php, I have the following:
在 中routes.php，我有以下内容：
Route::resource('backend/modules/module-name', 'Modules\ModuleName\Controllers\BackendController');
But whenever I try to access 'backend/modules/module-name', I get a ReflectionExceptionwith the following message:
但是每当我尝试访问“后端/模块/模块名称”时，我都会收到ReflectionException以下消息：
Class Modules\ModuleName\Controllers\BackendController does not exist
What may be causing the problem? When I run it in my local machine, it seems to work, but I can't get it to work on the webserver. Are there any server configuration scenarios, that may be causing this problem?
什么可能导致问题？当我在本地机器上运行它时，它似乎可以工作，但我无法让它在网络服务器上运行。是否有任何服务器配置方案可能导致此问题？
Since I don't have shell access to that webserver, I don't have composer installed on the webserver but it is installed on my local machine. I have uploaded all the files including vendordirectory, to the server.
由于我没有对该网络服务器的 shell 访问权限，因此我没有在网络服务器上安装 composer 但它安装在我的本地机器上。我已将包括vendor目录在内的所有文件上传到服务器。

From PSR-4 specification:
从PSR-4 规范：
All class names MUST be referenced in a case-sensitive fashion.
所有类名都必须以区分大小写的方式引用。
So you'll need to rename your modulesand controllersfolders to Modulesand Controllersrespectively.
因此，您需要将modules和controllers文件夹分别重命名为Modules和Controllers。
So it becomes:
所以就变成了：
app
- ...
- Modules
-- ModuleName
--- Controllers
---- BackendController.php
...
I wouldn't recommend renaming your namespaces to lowercase names because that just breaks the consistency in your code and project structure. It will be a headache to maintain and figure out which part of your namespace needs to be capitalized which one doesn't.
我不建议将命名空间重命名为小写名称，因为这会破坏代码和项目结构的一致性。维护和弄清楚命名空间的哪一部分需要大写，哪一部分不需要大写将是一件令人头疼的事情。

You should look at capitalization.
你应该看看大小写。
Probably you test it on Windows machine so path
可能你在 Windows 机器上测试它所以路径
'Modules\ModuleName\Controllers\BackendController'
is the same as
是相同的
'modules\ModuleName\controllers\BackendController'
But on Linux they are 2 different paths. You should probably change in your routes.phpline from
但在 Linux 上，它们是 2 条不同的路径。你可能应该改变你的routes.php行
Route::resource('backend/modules/module-name', 'Modules\ModuleName\Controllers\BackendController');
to
到
Route::resource('backend/modules/module-name', 'modules\ModuleName\controllers\BackendController');
