同理，JWT 可以用于更复杂的场景。

在这些情况下，多个实体的 ID 可能是相同的，以 ID  `foo` 为例，用户的 ID 是 `foo`，车的 ID 是 `foo`，博客的 ID 也是  `foo`。

为了避免 ID 冲突，在给用户创建 JWT 令牌时，可以为 `sub` 键的值加上前缀，例如 `username:`。因此，在本例中，`sub` 的值可以是：`username:johndoe`。

注意，划重点，`sub` 键在整个应用中应该只有一个唯一的标识符，而且应该是字符串。

## 检查

运行服务器并访问文档： <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>。

可以看到如下用户界面：

        headers={"WWW-Authenticate": authenticate_value},
    )
    try:
        payload = jwt.decode(token, SECRET_KEY, algorithms=[ALGORITHM])
        username: str = payload.get("sub")
        if username is None:
            raise credentials_exception
        scope: str = payload.get("scope", "")
        token_scopes = scope.split(" ")

Vamos a crear una dependencia `get_current_user`.

¿Recuerdas que las dependencias pueden tener sub-dependencias?

`get_current_user` tendrá una dependencia con el mismo `oauth2_scheme` que creamos antes.

De la misma manera que estábamos haciendo antes en la *path operation* directamente, nuestra nueva dependencia `get_current_user` recibirá un `token` como un `str` de la sub-dependencia `oauth2_scheme`:
