此处还创建了后续代码中要复用（`raise`）的 `HTTPException` 。

该异常包含了作用域所需的（如有），以空格分割的字符串（使用 `scope_str`）。该字符串要放到包含作用域的 `WWW-Authenticate` 请求头中（这也是规范的要求）。

{* ../../docs_src/security/tutorial005.py hl[105,107:115] *}

## 校验 `username` 与数据形状

我们可以校验是否获取了 `username`，并抽取作用域。

然后，使用 Pydantic 模型校验数据（捕获 `ValidationError` 异常），如果读取 JWT 令牌或使用 Pydantic 模型验证数据时出错，就会触发之前创建的 `HTTPException` 异常。
