如果没有接收到 HTTP 基础授权，就返回 HTTP 401 `"Unauthorized"` 错误。

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`

    from fastapi import Depends, FastAPI
    from fastapi.security import HTTPBasic, HTTPBasicCredentials

    app = FastAPI()

    security = HTTPBasic()


    @app.get("/users/me")
    def read_current_user(credentials: Annotated[HTTPBasicCredentials, Depends(security)]):

Então, quando você digitar o usuário e senha, o navegador os envia automaticamente no cabeçalho.

## 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.

Then, when you type that username and password, the browser sends them in the header automatically.

## 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:
