## `scopes`의 고급 사용법 { #advanced-usage-with-scopes }

OAuth2에는 "scopes"라는 개념이 있습니다.

이를 사용해 JWT 토큰에 특정 권한 집합을 추가할 수 있습니다.

그런 다음 이 토큰을 사용자에게 직접 제공하거나 제3자에게 제공하여, 특정 제한사항 하에서 API와 상호작용하도록 할 수 있습니다.

     * @return true if the paths could be equal
     */
    protected boolean pathNamesPossiblyEqual(final String path1, final String path2) {
        int p1, p2, l1, l2;

        // if unsure return this method returns true

        p1 = path1.lastIndexOf('/');
        p2 = path2.lastIndexOf('/');
        l1 = path1.length() - p1;
        l2 = path2.length() - p2;

留意標頭 `Authorization`，其值是以 `Bearer ` 開頭。

## 進階用法：`scopes` { #advanced-usage-with-scopes }

OAuth2 有「scopes」的概念。

你可以用它們替 JWT 權杖加上一組特定的權限。

接著你可以把這個權杖直接交給某個使用者或第三方，讓他們在一組受限條件下與你的 API 互動。

你可以在之後的「進階使用者指南」學到如何使用它們，以及它們如何整合進 **FastAPI**。

## 小結 { #recap }

如果你打开开发者工具，你会看到发送的数据只包含令牌。密码只会在第一个请求中用于认证用户并获取访问令牌，之后就不会再发送密码了：

## 使用 `scopes` 的高级用法 { #advanced-usage-with-scopes }

OAuth2 支持 “scopes”（作用域）。

你可以用它们为 JWT 令牌添加一组特定的权限。

然后你可以把这个令牌直接交给用户或第三方，在一组限制条件下与 API 交互。

在**高级用户指南**中你将学习如何使用它们，以及它们如何集成进 **FastAPI**。

## 小结 { #recap }

This could be useful, for example, to expose the same API under different prefixes, e.g. `/api/v1` and `/api/latest`.

This is an advanced usage that you might not really need, but it's there in case you do.
