当然，除了请求体参数外，你还可以在任何需要的时候声明额外的查询参数。

由于默认情况下单一值会被解释为查询参数，因此你不必显式地添加 `Query`，你可以这样写：

```Python
q: str | None = None
```

比如：

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[28] *}

/// info | 信息

`Body` 同样具有与 `Query`、`Path` 以及其他后面将看到的类完全相同的额外校验和元数据参数。

///

## 嵌入单个请求体参数 { #embed-a-single-body-parameter }

假设你只有一个来自 Pydantic 模型 `Item` 的请求体参数 `item`。

faster to develop against smaller subsets of the tests. For example, to run
tests for the default archive distribution on Fedora 28:

-----------------------------------------------------------
./gradlew :qa:os:fedora-28:distroTest.default-linux-archive
-----------------------------------------------------------

These test tasks can use the `--tests`, `--info`, and `--debug` parameters just like
