* Но для этого для конкретной конечной точки нужна аутентификация.
    * Поэтому, чтобы аутентифицироваться в нашем API, он отправляет HTTP-заголовок `Authorization` со значением `Bearer ` плюс сам токен.
    * Если токен содержит `foobar`, то содержимое заголовка `Authorization` будет: `Bearer foobar`.

## Класс `OAuth2PasswordBearer` в **FastAPI** { #fastapis-oauth2passwordbearer }

/// info | Bilgi

Burada `Bearer` değerine sahip ek `WWW-Authenticate` header’ını döndürmemiz de spesifikasyonun bir parçasıdır.

Herhangi bir HTTP (hata) durum kodu 401 "UNAUTHORIZED", ayrıca `WWW-Authenticate` header’ı da döndürmelidir.

Bearer token’lar (bizim durumumuz) için bu header’ın değeri `Bearer` olmalıdır.

Aslında bu ekstra header’ı atlayabilirsiniz, yine de çalışır.

Тепер продовжимо з попереднього розділу і додамо відсутні частини, щоб отримати повний потік безпеки.

## Отримайте `username` і `password` { #get-the-username-and-password }

Ми використаємо утиліти безпеки **FastAPI**, щоб отримати `username` і `password`.
