但在本例中，**FastAPI** 应用会处理 API 与身份验证。

下面，我们来看一下简化的运行流程：

- 用户在前端输入 `username` 与`password`，并点击**回车**
- （用户浏览器中运行的）前端把 `username` 与`password` 发送至 API 中指定的 URL（使用 `tokenUrl="token"` 声明）
- API 检查 `username` 与`password`，并用令牌（`Token`） 响应（暂未实现此功能）：
  - 令牌只是用于验证用户的字符串
  - 一般来说，令牌会在一段时间后过期
    - 过时后，用户要再次登录
    - 这样一来，就算令牌被人窃取，风险也较低。因为它与永久密钥不同，**在绝大多数情况下**不会长期有效
- 前端临时将令牌存储在某个位置
- 用户点击前端，前往前端应用的其它部件
- 前端需要从 API 中提取更多数据：

            raise self.make_not_authenticated_error() from e
        username, separator, password = data.partition(":")
        if not separator:
            raise self.make_not_authenticated_error()
        return HTTPBasicCredentials(username=username, password=password)

### Visit <http://localhost:8080>

You will be redirected to dex login screen - click "Login with email", enter username password
> username: ******@****.***
> password: password

and then click "Grant access"

On the browser now you shall see the list of buckets output, along with your temporary credentials obtained from MinIO.

```
