Ben önleyici kullanarak yapıyorum. İndex.html dosyasına eklenebilecek bir kütüphane dosyası oluşturdum. Bu şekilde, geri kalan servis çağrılarınız için global hata işleme uygulayacak ve tüm hataları tek tek önemsemeniz gerekmeyecek. Daha sonra temel kimlik doğrulama giriş kütüphanemi de yapıştırdım. Orada da 401 hatasını kontrol ettiğimi ve farklı bir yere yönlendirdiğimi görebilirsiniz. Bkz. Lib / ea-basic-auth-login.js
