Call to a member function middleware() on null
提问by ramzi trabelsi
I use the following middleware in routing Laravel:
我在路由 Laravel 时使用以下中间件：
Route::group(['prefix' => 'api/'], function() {
Route::resource('admin', 'adminController')->middleware('auth');
Route::resource('profile', 'profileController')->middleware('role');
});
I get this error when i call 'admin' or 'profile' path in URL
当我在 URL 中调用“admin”或“profile”路径时出现此错误

It is because Route::resource()does not return anything. Its void. It doesn't return an object.
这是因为Route::resource()不返回任何东西。其空。它不返回对象。
Laravel 5.4 - Illuminate\Routing\Router@resource
Laravel 5.4 - Illuminate\Routing\Router@resource
In Laravel 5.5 (in development), Route::resource()will be returning an object for fluently adding options to.
在 Laravel 5.5（开发中）中，Route::resource()将返回一个用于流畅地添加选项的对象。

Most likely your resource controller is not resolving to an actual controller. Some things to check
很可能您的资源控制器没有解析为实际控制器。需要检查的一些事项
- Check you actually have an adminController, and that the class name is in the correct case
- Check that your controller is in the default namespace and, if not, change the controller namespace, or add a namespace attribute to your route
- Check that your controller is not causing an exception on start that is being ignored resulting in you having a null controller.
- 检查您实际上有一个 adminController，并且类名的大小写正确
- 检查您的控制器是否在默认命名空间中，如果不是，请更改控制器命名空间，或向您的路由添加命名空间属性
- 检查您的控制器是否在启动时不会导致被忽略的异常，从而导致您拥有一个空控制器。

Simply reverse the order:
只需颠倒顺序：
Route::middleware('scope:clock-in')->resource('clock', 'ClockController');
As lagbox stated:
正如lagbox所说：
Route::resource()does not return anything.
Route::resource()不返回任何东西。
However middleware does.
但是中间件可以。
