ERR_TOO_MANY_REDIRECTS laravel管理/登錄頁面

Question

我有三個具有三個不同視圖和路線的登錄名。 每當我按下localhost：8080 / admin / login時，它就會顯示錯誤ERR_TOO_MANY_REDIRECTS。 當我點擊admin /的儀表板時，它成功地將我重定向到admin / login。

當我替換$ this-> middleware（'auth：admin'）時，在AdminController中； 使用$ this-> middleware（'guest：admin'）; 在__constructor函數中，重定向問題得到解決，但是當我轉到admin / home時，它不會重定向到admin / login。

我正在使用最新的laravel 5.7.xx，並且沒有使用其內置身份驗證視圖。 它是我定制的。

Answer 1

原因是因為您使用$this->middleware('auth:admin')將整個AdminController專用於經過身份驗證的用戶。 因此，當您點擊管理員url時，該應用程序將繼續前后重定向。 要解決此問題，請在中間件中添加除外方法，以將索引方法從中間件保護中排除。 應該是$this->middleware('auth:admin')->except(['index']);
