我的索引文件：@foreach ($categories as $category)                        <div class="panel panel-default">                            <div class="panel-heading">                                <h4 class="panel-title"><a href="{{ route('category', app()->getLocale(), $category->name) }}">{{ $category->name }}</a></h4>                            </div>                        </div>@endforeach我的路線文件：Route::prefix('/{language}')->group(function () {Route::get('/', ['uses' => 'IndexController@home', 'as' => 'home']);Route::post('/', ['uses' => 'IndexController@price', 'as' => 'price']);Route::get('contact', ['uses' => 'ContactController@show', 'as' => 'contact']);Route::post('contact', ['uses' => 'ContactController@send', 'as' => 'contact-send']);Route::get('/category/{category}', ['uses' => 'CategoryController@show', 'as' => 'category']); });錯誤文本：缺少 [路線：類別] [URI：{語言}/類別/{類別}] 所需的參數。（查看：/Applications/MAMP/htdocs/shop/resources/views/index.blade.php）我認為問題是我錯誤地插入了第二個參數，請幫助我，預先感謝；）
