Laravel：檢查蛞蝓的路線是等於在數據庫

Question

段塞我有一個像/locations/name-of-the-location.ID

我的路線的網址是：

Route::get('locations/{slug}.{location}', ['as' => 'locations.show', 'uses' => 'LocationsController@show'])->where([ 
    'location' => '[0-9]+', 
    'slug' => '[a-z0-9-]+' 
]); 

現在我要檢查，如果提供的鼻涕蟲是一樣的用我的模型保存在數據庫列'slug'中（因爲slug可能已經改變）。如果沒有，那麼我想重定向到正確的路徑。

哪裏可以做到這一點？我想到了\ App \ Providers \ RouteServiceProvider-但是當我嘗試在那裏使用Route::currentRouteName()時，我得到NULL，可能是因爲在RouteServiceProvider的boot（）方法中對於該方法來說「太早」。

我可以做的是使用path（），但對我來說這看起來有點髒，因爲我使用其他語言的路由前綴。

這裏就是我想（我用一個小的輔助類RouteSlug） - 當然這是行不通的：

public function boot() 
{ 
    parent::boot(); 

    if (strstr(Route::currentRouteName(), '.', true) == 'locations') 
    { 
     Route::bind('location', function ($location) { 
      $location = \App\Location::withTrashed()->find($location); 
      $parameters = Route::getCurrentRoute()->parameters(); 
      $slug = $parameters['slug']; 

      if ($redirect = \RouteSlug::checkRedirect(Route::getCurrentRoute()->getName(), $location->id, $location->slug, $slug)) 
      { 
       return redirect($redirect); 
      } 
      else 
      { 
       return $location; 
      } 

     }); 
    } 
} 

Answer 1

所以最後我想出了一箇中間人分別是：

應用程序\ HTTP \中間件\ CheckSlug

public function handle($request, Closure $next) 
{ 
    if ($redirect = RouteSlug::checkRedirect(Route::currentRouteName(), $request->location->id, $request->location->slug, $request->slug)) 
    { 
     return redirect($redirect); 
    } 

    return $next($request); 
} 

我的路線是這樣的：

Route::get('locations/{slug}.{location}', ['as' => 'locations.show', 'uses' => 'LocationsController@show'])->where([ 
    'location' => '[0-9]+', 
    'slug' => '[a-z0-9-]+' 
])->middleware(App\Http\Middleware\CheckSlug::class); 

Answer 2

您的路線應該是這樣的：

Route::get('locations/{id}/{slug}', ['as' => 'locations.show', 'uses' => 'LocationsController@show'])->where([ 
    'id' => '[0-9]+', 
    'slug' => '[a-z0-9-]+' 
]); 

而且LocationsController@show應看起來像這樣：

public function show($id, $slug) 
{ 
    // Add 'use App\Location' to the top of this controller 
    $location = Location::find($id); 

    // I'm not sure what you were doing with the soft deleted items 
    // but you might want to restore them if you are using them 
    if ($location->trashed()) $location->restore(); 

    if ($slug != $location->slug) { 
     return redirect()->route('locations.show', ['id' => $id, 'slug' => $location->slug]); 
    } 

    // Return the view 

}
