使用 Pydantic 验证数据可以确保数据中含有由作用域组成的**字符串列表**，以及 `username` 字符串等内容。

反之，如果使用**字典**或其它数据结构，就有可能在后面某些位置破坏应用，形成安全隐患。

还可以使用用户名验证用户，如果没有用户，也会触发之前创建的异常。

## 校验 `scopes`

接下来，校验所有依赖项和依赖要素（包括*路径操作*）所需的作用域。这些作用域包含在令牌的 `scopes` 里，如果不在其中就会触发 `HTTPException` 异常。

为此，要使用包含所有作用域**字符串列表**的 `security_scopes.scopes`， 。
