Sie können sie von `fastapi.security` importieren:

```python
from fastapi.security import (
    APIKeyCookie,
    APIKeyHeader,
    APIKeyQuery,
    HTTPAuthorizationCredentials,
    HTTPBasic,
    HTTPBasicCredentials,
    HTTPBearer,
    HTTPDigest,
    OAuth2,
    OAuth2AuthorizationCodeBearer,
    OAuth2PasswordBearer,
    OAuth2PasswordRequestForm,
    OAuth2PasswordRequestFormStrict,
    OpenIdConnect,

并返回含 `Basic` 值的请求头 `WWW-Authenticate`以及可选的 `realm` 参数。

HTTP 基础授权让浏览器显示内置的用户名与密码提示。

输入用户名与密码后，浏览器会把它们自动发送至请求头。

## 简单的 HTTP 基础授权

* 导入 `HTTPBsic` 与 `HTTPBasicCredentials`
* 使用 `HTTPBsic` 创建**安全概图**
* 在*路径操作*的依赖项中使用 `security`
* 返回类型为 `HTTPBasicCredentials` 的对象：
    * 包含发送的 `username` 与 `password`

## Simple HTTP Basic Auth

* Import `HTTPBasic` and `HTTPBasicCredentials`.
* Create a "`security` scheme" using `HTTPBasic`.
* Use that `security` with a dependency in your *path operation*.
* It returns an object of type `HTTPBasicCredentials`:
    * It contains the `username` and `password` sent.

## Einfaches HTTP Basic Auth

* Importieren Sie `HTTPBasic` und `HTTPBasicCredentials`.
* Erstellen Sie mit `HTTPBasic` ein „`security`-Schema“.
* Verwenden Sie dieses `security` mit einer Abhängigkeit in Ihrer *Pfadoperation*.
* Diese gibt ein Objekt vom Typ `HTTPBasicCredentials` zurück:
    * Es enthält den gesendeten `username` und das gesendete `password`.
