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。

* `summary`: Short description for the example.
* `description`: A long description that can contain Markdown text.
* `value`: This is the actual example shown, e.g. a `dict`.
* `externalValue`: alternative to `value`, a URL pointing to the example. Although this might not be supported by as many tools as `value`.

You can use it like this:

//// tab | Python 3.10+

```Python hl_lines="23-49"

    * Campos de texto (`str`) definiendo longitudes mínimas y máximas.
    * Números (`int`, `float`) con valores mínimos y máximos, etc.

* Validación para tipos más exóticos como:
    * URL.
    * Email.
    * UUID.
    * ...y otros.

Toda la validación es manejada por **Pydantic**, que es robusto y sólidamente establecido.

Oder Sie können sie im Parameter `response_class` verwenden:


```Python hl_lines="2  7  9"
{!../../docs_src/custom_response/tutorial006b.py!}
```

Wenn Sie das tun, können Sie die URL direkt von Ihrer *Pfadoperation*-Funktion zurückgeben.

In diesem Fall ist der verwendete `status_code` der Standardcode für die `RedirectResponse`, also `307`.
