作用域表示的是**权限**。

OpenAPI 中（例如 API 文档）可以定义**安全方案**。

这些安全方案在使用 OAuth2 时，还可以声明和使用作用域。

**作用域**只是（不带空格的）字符串。

常用于声明特定安全权限，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**只是声明特定权限的字符串。

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，它们都只是字符串而已。
