尋求幫助獲取表單驗證在Laravel 5.2中工作

Question

我正在嘗試在Bitnami WAMP上安裝新的Laravel 5.2安裝的驗證工作，並且沒有運氣。我已經嘗試了在其他地方提供的Laravel 5.2 $errors not appearing in Blade這兩個建議，並且從甚至還沒有開始使用驗證的頁面返回以下錯誤。

當我試圖把我的工作路線（應用程序/ HTTP/routes.php文件）上Route::group(['middleware' => ['web']]，函數（）{...等等如下：

protected $middleware = [ 
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class, 
    \Illuminate\View\Middleware\ShareErrorsFromSession::class, 
]; 

我收到以下錯誤messegaes：

+ RuntimeException in Request.php line 852: Session store not set on request. 
+ in Request.php line 852 at Request->session() 
+ in ShareErrorsFromSession.php line 42 
+ at ShareErrorsFromSession->handle(object(Request), object(Closure)) 
+ at call_user_func_array(array(object(ShareErrorsFromSession), 'handle'), array(object(Request), object(Closure))) in Pipeline.php line 124 
+ at Pipeline->Illuminate\Pipeline{closure}(object(Request)) at call_user_func(object(Closure), object(Request)) in Pipeline.php line 32 
+ at Pipeline->Illuminate\Routing{closure}(object(Request)) in CheckForMaintenanceMode.php line 44 
+ at CheckForMaintenanceMode->handle(object(Request), object(Closure)) 
+ at call_user_func_array(array(object(CheckForMaintenanceMode), 'handle'), array(object(Request), object(Closure))) in Pipeline.php line 124 
+ at Pipeline->Illuminate\Pipeline{closure}(object(Request)) at call_user_func(object(Closure), object(Request)) in Pipeline.php line 32 
+ at Pipeline->Illuminate\Routing{closure}(object(Request)) at call_user_func(object(Closure), object(Request)) in Pipeline.php line 103 
+ at Pipeline->then(object(Closure)) in Kernel.php line 132 
+ at Kernel->sendRequestThroughRouter(object(Request)) in Kernel.php line 99 
+ at Kernel->handle(object(Request)) in index.php line 54 

，當我試圖在保護$middleware = []移動我的保護$ middlewareGroups網絡（應用程序/ HTTP/Kernel.php），具體如下：

Route::group(['middleware' => 'web'], function() { 
    Route::resource('country', 'Region\CountryController'); 
}); 

我得到的錯誤信息：

+ in EncryptionServiceProvider.php line 31 
+ at EncryptionServiceProvider->Illuminate\Encryption{closure}(object(Application), array()) in Container.php line 735

+ at Kernel->sendRequestThroughRouter(object(Request)) in Kernel.php line 99 
+ at Kernel->handle(object(Request)) in index.php line 54 

這些錯誤提出了一個網頁，甚至不要求驗證還沒有上。

當我嘗試在存儲方法更新後重定向到的刀片模板上獲得$錯誤時，$錯誤也未定義。

任何幫助都是值得歡迎的，因爲我一直試圖在新的Laravel 5.2安裝中解決這個問題好幾天。

謝謝

在你的路由定義（在這裏張貼作爲一個正式的答案）

你提到的第二個方法是更方便，應用中間件（或中間件團體，web是）。

web組包括與會話和加密相關的中間件。 Laravel使用值APP_KEY來加密所有會話數據，並將表單輸入和驗證錯誤存儲在會話中。

在會話訪問期間的某個時刻，Laravel會嘗試創建en Encrypter對象，如果應用程序密鑰的長度不是32個字符，則會失敗。我剛剛發現閱讀源代碼，但您只需要知道，當您執行應用程序的初始配置時，.env文件應該有一個32長的隨機字符串，如APP_KEY。 Artisan命令key:generate爲你做到了。
