Laravel 5.4在全局中間件中訪問$ errors變量

Question

我有一個全局中間件，用於檢查應用程序是否處於開發模式，如果是，則返回登錄表單視圖，此視圖驗證登錄，然後使用errors變量顯示任何驗證錯誤：

應用程序\ HTTP \內核在我看來

/** 
* The application's global HTTP middleware stack. 
* 
* @var array 
*/ 
protected $middleware = [ 
    \App\Http\Middleware\CheckForDevelopmentMode::class, 
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class, 
    \App\Http\Middleware\TrimStrings::class, 
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class, 
]; 

$錯誤變量

{!! $errors->first('email', '<span class="help-block">:message</span>') !!} 

這Laravel 5.2偉大的工作，但瓦特當我更新到L5.4會話並且錯誤共享在網絡中間件組中被實例化時，所以現在在L5.4中，我的全局中間件中沒有訪問會話。

/** 
* The application's route middleware groups. 
* 
* @var array 
*/ 
protected $middlewareGroups = [ 
    'web' => [ 
     \App\Http\Middleware\EncryptCookies::class, 
     \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class, 
     \Illuminate\Session\Middleware\StartSession::class, 
     \Illuminate\View\Middleware\ShareErrorsFromSession::class, 
     \App\Http\Middleware\VerifyCsrfToken::class, 
     \Illuminate\Routing\Middleware\SubstituteBindings::class, 
    ], 
    'api' => [ 
     'throttle:60,1', 
     'bindings', 
    ], 
]; 

如何在全局中間件中手動實例化新會話，以便我可以使用$ errors變量進行驗證？

Answer 1

我發現最簡單的方法是啓動會話並在全局中間件上共享錯誤，以便我們可以訪問視圖中的$ errors變量。如果有人推薦另一種解決方案，我會改變接受的答案。

/** 
* The application's global HTTP middleware stack. 
* 
* @var array 
*/ 
protected $middleware = [ 
    // Start the session and share errors globally so that we can access the 
    // errors variable in the development mode view. 
    \Illuminate\Session\Middleware\StartSession::class, 
    \Illuminate\View\Middleware\ShareErrorsFromSession::class, 
    \App\Http\Middleware\CheckForDevelopmentMode::class, 
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class, 
    \App\Http\Middleware\TrimStrings::class, 
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class, 
];
