Laravel 5.4路由组和资源搞乱了参数

This resource definition is good:

Route::resource('servers', 'ServerController');

Gives:

+--------+-----------+-----------------------+-----------------+-----------------------------------------------+--------------+
| Domain | Method    | URI                   | Name            | Action                                        | Middleware   |
+--------+-----------+-----------------------+-----------------+-----------------------------------------------+--------------+
|        | GET|HEAD  | servers               | servers.index   | App\Http\Controllers\ServerController@index   | web          |
|        | POST      | servers               | servers.store   | App\Http\Controllers\ServerController@store   | web          |
|        | GET|HEAD  | servers/create        | servers.create  | App\Http\Controllers\ServerController@create  | web          |
|        | GET|HEAD  | servers/{server}      | servers.show    | App\Http\Controllers\ServerController@show    | web          |
|        | PUT|PATCH | servers/{server}      | servers.update  | App\Http\Controllers\ServerController@update  | web          |
|        | DELETE    | servers/{server}      | servers.destroy | App\Http\Controllers\ServerController@destroy | web          |
|        | GET|HEAD  | servers/{server}/edit | servers.edit    | App\Http\Controllers\ServerController@edit    | web          |
+--------+-----------+-----------------------+-----------------+-----------------------------------------------+--------------+

But I need to wrap it into a group with prefix like this:

Route::group(['prefix' => 'servers'], function()
{
    Route::resource('/', 'ServerController', ['names' => 'servers']);
});

And here comes the problem, because of prefix the parameterised routes' parameters are empty:

+--------+-----------+-----------------+-----------------+-----------------------------------------------+--------------+
| Domain | Method    | URI             | Name            | Action                                        | Middleware   |
+--------+-----------+-----------------+-----------------+-----------------------------------------------+--------------+
|        | GET|HEAD  | servers         | servers.index   | App\Http\Controllers\ServerController@index   | web          |
|        | POST      | servers         | servers.store   | App\Http\Controllers\ServerController@store   | web          |
|        | GET|HEAD  | servers/create  | servers.create  | App\Http\Controllers\ServerController@create  | web          |
|        | GET|HEAD  | servers/{}      | servers.show    | App\Http\Controllers\ServerController@show    | web          |
|        | PUT|PATCH | servers/{}      | servers.update  | App\Http\Controllers\ServerController@update  | web          |
|        | DELETE    | servers/{}      | servers.destroy | App\Http\Controllers\ServerController@destroy | web          |
|        | GET|HEAD  | servers/{}/edit | servers.edit    | App\Http\Controllers\ServerController@edit    | web          |
+--------+-----------+-----------------+-----------------+-----------------------------------------------+--------------+

So the servers/1 goes 404. Is there any way to fix this problem?

Based on your comments:

You want to add the namespace and middleware to the resource route. You can achieve this by adding middleware and namespace key in the third parameter of your resource controller like this.

Route::resource('servers', 'ServerController', ['middleware' => 'xyz', 'namespace' => 'xyz']);

EDIT:

If a namespace is not working you can assign a namespace to the controller.

Route::resource('servers', 'Xyz\ServerController', ['middleware' => 'xyz']);

You can use method parameters to customize all params in route. Example:

Route::prefix('teams')->group(function () {
  Route::resource('', 'TeamController')->parameters(['' => 'team']);
});
