Я роблю це за допомогою перехоплювачів. Я створив файл бібліотеки, який можна додати до файлу index.html. Таким чином ви матимете глобальну обробку помилок для своїх дзвінків служби відпочинку та не потрібно дбати про всі помилки окремо. Далі вниз я також вставив свою основну бібліотеку для входу в систему-авторист. Там ви бачите, що я також перевіряю наявність помилки 401 та переадресацію на інше місце. Див.
