# HTTP Basic Auth { #http-basic-auth }

En basit senaryolarda HTTP Basic Auth kullanabilirsiniz.

HTTP Basic Auth’ta uygulama, içinde kullanıcı adı ve şifre bulunan bir header bekler.

Eğer bunu almazsa HTTP 401 "Unauthorized" hatası döndürür.

Ayrıca değeri `Basic` olan ve isteğe bağlı `realm` parametresi içerebilen `WWW-Authenticate` header’ını da döndürür.

Bu da tarayıcıya, kullanıcı adı ve şifre için entegre giriş penceresini göstermesini söyler.

* El frontend necesita obtener más datos de la API.
    * Pero necesita autenticación para ese endpoint específico.
    * Así que, para autenticarse con nuestra API, envía un `header` `Authorization` con un valor de `Bearer ` más el token.
    * Si el token contiene `foobar`, el contenido del `header` `Authorization` sería: `Bearer foobar`.

    The upcoming Android Studio runs in a JVM but has classes from Android and that confused OkHttp!

 *  Fix: Include the header `Accept: text/event-stream` for SSE calls. This header is not added if
    the request already contains an `Accept` header.

 *  Fix: Don't crash with a `NullPointerException` if a server sends a close while we're sending a
    ping. OkHttp had a race condition bug.
