RouteCollection.php 第 161 行中的 NotFoundHttpException：laravel 5.3

Question

在 laravel 中，我正在尝试 link 到特定页面，但它显示

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]) }}  

在路线中：

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

在控制器中：

  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

您的控制器文件中似乎有一个 ` 字符

class FilesController extends Controller{
      public function deleteFile($id)//it was right here 
      {
          $file = Resource::find($id);
          Storage::delete(config('app.fileDestinationPath').'/'.$file->filename);
          $file->delete();
          return redirect()->to('/upload');
      }
}

试试这个

Answer 2

你的参数有误。它应该 {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');
