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 `HTTPBasic` 与 `HTTPBasicCredentials`
* 使用 `HTTPBasic` 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`

## HTTP Basic Auth Simples

* Importe `HTTPBasic` e `HTTPBasicCredentials`.
* Crie um "esquema `security`" utilizando `HTTPBasic`.
* Utilize o `security` com uma dependência em sua *operação de rota*.
* Isso retorna um objeto do tipo `HTTPBasicCredentials`:
    * Isto contém o `username` e o `password` enviado.

## 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`.
