php - RouteCollection.php 中的 NotFoundHttpException 第 161 行 : laravel 5. 3

Question

在 laravel 中，我试图链接到一个特定的页面，但它正在显示

NotFoundHttpException in RouteCollection.php line 161:

这是我的代码，请帮我找出错误
在我看来:

{{ link_to_route('deleteFile', 'Delete', [$file->resid]) }}  

在 route :

Route::get('/deleteFile/{$id}',
['as'=>'deleteFile','uses'=>'FilesController@deleteFile']);

在 Controller 中:

  class FilesController extends Controller{
public function deleteFile($id)
    {

         $file = Resource::find($id);
      Storage::delete(config('app.fileDestinationPath').'/'.$file->filename);
        $file->delete();
        return redirect()->to('/upload');
    }}

这是我的模型代码:

namespace App;

use Illuminate\Database\Eloquent\Model;

class Resource extends Model
{

    protected $table='resource';
    public $fillable=['resname'];
}

Answer 1

你的参数有误。它应该是 {id} 而不是 {$id}

改变

 Route::get('/deleteFile/{$id}',
 ['as'=>'deleteFile','uses'=>'FilesController@deleteFile']);

到

 Route::get('/deleteFile/{id}',
 ['as'=>'deleteFile','uses'=>'FilesController@deleteFile']);

和 Laravel 5.3 现在支持使用 name

 Route::get('/deleteFile/{id}','FilesController@deleteFile')->name('deleteFile');
