## Benutzerdefinierte Header hinzufügen { #add-custom-headers }

Es gibt Situationen, in denen es nützlich ist, dem HTTP-Error benutzerdefinierte Header hinzuzufügen. Zum Beispiel in einigen Sicherheitsszenarien.

Sie werden es wahrscheinlich nicht direkt in Ihrem Code verwenden müssen.

Aber falls Sie es für ein fortgeschrittenes Szenario benötigen, können Sie benutzerdefinierte Header hinzufügen:

    * Es benötigt jedoch eine Authentifizierung für diesen bestimmten Endpunkt.
    * Um sich also bei unserer API zu authentifizieren, sendet es einen Header `Authorization` mit dem Wert `Bearer ` plus dem Token.
    * Wenn der Token `foobar` enthielte, wäre der Inhalt des `Authorization`-Headers: `Bearer foobar`.

## **FastAPI**s `OAuth2PasswordBearer` { #fastapis-oauth2passwordbearer }

* HTTP Basic.
* **OAuth2** (also with **JWT tokens**). Check the tutorial on [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).

그 후, 테스트에서도 동일하게 적용하면 됩니다.

예시:

* *경로* 혹은 *쿼리* 매개변수를 전달하려면, URL 자체에 추가한다.
* JSON 본문을 전달하려면, 파이썬 객체 (예를들면 `dict`) 를 `json` 파라미터로 전달한다.
* JSON 대신 *폼 데이터* 를 보내야한다면, `data` 파라미터를 대신 전달한다.
* *헤더* 를 전달하려면, `headers` 파라미터에 `dict` 를 전달한다.
* *쿠키* 를 전달하려면, `cookies` 파라미터에 `dict` 를 전달한다.

* **Editor desteği**.
* **Tip kontrolü**.

...ve **FastAPI** aynı belirteçleri şunlar için de kullanıyor:

* **Gereksinimleri tanımlama**:  request path parameters, query parameters, headers, bodies, dependencies, ve benzeri gereksinimlerden
* **Verileri çevirme**: Gönderilen veri tipinden istenilen veri tipine çevirme.
* **Verileri doğrulama**: Her gönderilen verinin:

    * JSON.
    * Path parameters.
    * Query parameters.
    * Cookies.
    * Headers.
    * Forms.
    * Files.
* <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of output data: converting from Python data and types to network data (as JSON):

* HTTP Basic.
* **OAuth2** (também com **tokens JWT**). Confira o tutorial em [OAuth2 com JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Chaves de API em:
    * Headers.
    * parâmetros da Query.
    * Cookies etc.

Além disso, todos os recursos de segurança do Starlette (incluindo **cookies de sessão**).
