    Android 10. Android uses reflection to look up a magic `checkServerTrusted()` method and we
    didn't have it.
 *  Fix: Explicitly specify the remote server name when making HTTPS connections on Android 5. In
    4.3.0 we introduced a regression where server name indication (SNI) was broken on Android 5.

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。

### `Scope`（作用域）

  * A pod can specify its own Hostname and Subdomain via annotations (<code>pod.beta.kubernetes.io/hostname, pod.beta.kubernetes.io/subdomain)</code>. If the Subdomain matches the name of a [headless service](http://kubernetes.io/docs/user-guide/services/#headless-services) in the same namespace, a DNS A record is also created for the pod’s FQDN.
