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）

OAuth2 还支持客户端发送**`scope`**表单字段。

虽然表单字段的名称是 `scope`（单数），但实际上，它是以空格分隔的，由多个**scope**组成的长字符串。

**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`
