Question

我是Laravel的新学员，目前我正在玩观点。但是，在我的视图中传递变量之后，我得到了这个异常。基本上它说这条路线不存在。

<ListView x:Name="listaContatti"
    IsItemClickEnabled="True" MaxHeight="200"
    SelectedItem="{Binding ClientiContatti,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"
    ItemsSource="{Binding ListaClientiContatti,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <template:ItemTemplateContatti />
        </DataTemplate>
    </ListView.ItemTemplate>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment" Value="Stretch" />
            <Setter Property="Padding" Value="0" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

所以这就是我正在做的事情

routes.php文件

NotFoundHttpException in RouteCollection.php line 161:

at RouteCollection->match(object(Request)) in Router.php line 821
at Router->findRoute(object(Request)) in Router.php line 691

at Kernel->handle(object(Request)) in index.php line 54

CommentsController.php

Route::get('show_comment/{$id}','CommentsController@showComment');

最后我的观点很简单。

class CommentsController extends Controller
{

public function index()
{

}
/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */
public function create()
{
    //
    return "inside Create method";
}

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
{
    //
}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function show($id)
{
    return "Show method:" .$id;
}

/**
 * Show the form for editing the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function edit($id)
{
    //
}

/**
 * Update the specified resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
  public function update(Request $request, $id)
  {
    //
  }


public function destroy($id)
{
    //

}

public function contact(){
    return view('contacts');
}


public function showComment($id){
    return view('show_comment') -> with('id',$id);
  }

}

我错过了什么？

谢谢，

正如@Xatenev在评论中所说，它应该只是在路线中删除$以便改变：

Route::get('show_comment/{$id}','CommentsController@showComment');

到：

Route::get('show_comment/{id}','CommentsController@showComment');

将变量传递到视图中
