本章添加上一章示例中欠缺的部分，实现完整的安全流。

## 获取 `username` 和 `password`

首先，使用 **FastAPI** 安全工具获取 `username` 和 `password`。

OAuth2 规范要求使用**密码流**时，客户端或用户必须以表单数据形式发送 `username` 和 `password` 字段。

并且，这两个字段必须命名为 `username` 和 `password` ，不能使用 `user-name` 或 `email` 等其它名称。

不过也不用担心，前端仍可以显示终端用户所需的名称。

数据库模型也可以使用所需的名称。

但对于登录*路径操作*，则要使用兼容规范的 `username` 和 `password`，（例如，实现与 API 文档集成）。

该规范要求必须以表单数据形式发送 `username` 和 `password`，因此，不能使用 JSON 对象。

Redirection from OpenID Provider

To login to MinIO, the user first loads the MinIO console on their browser, and selects the OpenID Provider they wish to use (the `MINIO_IDENTITY_OPENID_DISPLAY_NAME` value is shown here). The user is then redirected to the OpenID provider's login page and performs necessary login actions (e.g. entering credentials, responding to MFA authentication challenges, etc). After successful login, the user is redirected back to the MinIO console. This redirect URL is...
