FastAPI 现在会：

- 对数据进行**校验**，确保最大长度为 50 个字符
- 当数据无效时向客户端展示**清晰的错误**
- 在 OpenAPI 模式的*路径操作*中**记录**该参数（因此会出现在**自动文档 UI** 中）

## 另一种（旧的）方式：把 `Query` 作为默认值 { #alternative-old-query-as-the-default-value }

早期版本的 FastAPI（<dfn title="早于 2023-03">0.95.0</dfn> 之前）要求你把 `Query` 作为参数的默认值，而不是放在 `Annotated` 里。你很可能会在别处看到这种写法，所以我也给你解释一下。
