/// tip | Consejo

Tal vez recuerdes que los request bodies también se declaran con modelos de Pydantic.

Aquí **FastAPI** no se confundirá porque estás usando `Depends`.

/// check | Revisa

El modo en que este sistema de dependencias está diseñado nos permite tener diferentes dependencias (diferentes "dependables") que todas devuelven un modelo `User`.

查询参数的值就是：

* `skip=20`：在 URL 中设定的值
* `limit=10`：使用默认值

## 可选参数

同理，把默认值设为 `None` 即可声明**可选的**查询参数：

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

本例中，查询参数 `q` 是可选的，默认值为 `None`。

/// check | 检查

注意，**FastAPI** 可以识别出 `item_id` 是路径参数，`q` 不是路径参数，而是查询参数。

///

/// note | 笔记

因为默认值为 `= None`，FastAPI 把 `q` 识别为可选参数。
