OAuth2 的设计目标是为了让后端或 API 独立于服务器验证用户身份。

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
