**作用域**只是不带空格的字符串。

常用于声明指定安全权限，例如：

* 常见用例为，`users:read` 或 `users:write`
* 脸书和 Instagram 使用 `instagram_basic`
* 谷歌使用 `https://www.googleapis.com/auth/drive`

/// info | "说明"

OAuth2 中，**作用域**只是声明指定权限的字符串。

是否使用冒号 `:` 等符号，或是不是 URL 并不重要。

这些细节只是特定的实现方式。

对 OAuth2 来说，都只是字符串而已。

## 获取 `username` 和 `password` 的代码

接下来，使用 **FastAPI** 工具获取用户名与密码。
