Laravel请求，彦博显示变量

Question

我route.php象下面这样：

Route::get('/edit/{num}', [ 
     'as' => 'department.edit', 
     'middleware' => ['admin'], 
     'uses' => 'DepartmentsController@edit' 
    ]); 

    Route::post('/update/{num}', [ 
     'as' => 'department.update', 
     'middleware' => ['admin'], 
     'uses' => 'DepartmentsController@update' 
    ]); 

而且edit.blade.php如下：

{!! Form::model($department, array('route' => ['department.update', Crypt::encrypt($department->id)], 'id' => 'department_update', 'class' => 'form-horizontal row-border')) !!} 
       @include('admin.departments._form') 
       {!! Form::label('', '', array('class' => 'col-md-2 control-label')) !!} 
       {!! Form:: submit('Update', ['class' => 'btn btn-success']) !!} 
      {!!form::close()!!} 

而且DepartmentsController.phpupdate()为：

public function update($id, Request $request) { 
     $id = Crypt::decrypt($id); 
     dd($_POST); 
} 

以上显示的是POST变量：

array:3 [▼ 
    "_token" => "UI6tBMuJlwmGZuaeB9ilJq6v0wUMOgKRlEY4eY0I" 
    "name" => "Material Management" 
    "department_code" => "MMD" 
] 

但是，如果我试图输出dd($request)，它会引发错误

ReflectionException在AbstractCloner.php行245：1类不存在

的哪些错误？我犯了什么错误

试试这个方法，将你的$request移动到第一个参数。

public function update(Request $request, $id) { 
     $id = Crypt::decrypt($id); 
     dd($request->all()); 
     dd($_POST); 
}
