``` //// Em ambos os casos, isso significa que `item` poderia ser um `int` ou um `str`. #### Possivelmente `None` { #possibly-none } Você pode declarar que um valor pode ter um tipo, como `str`, mas que ele também pode ser `None`. No Python 3.6 e superior (incluindo o Python 3.10) você pode declará-lo importando e utilizando `Optional` do módulo `typing`. ```Python hl_lines="1 4"Created: Sun Dec 28 07:19:09 GMT 2025 - Last Modified: Wed Dec 17 20:41:43 GMT 2025 - 16.7K bytes - Click Count (0) -

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。Created: Sun Dec 28 07:19:09 GMT 2025 - Last Modified: Mon Nov 18 02:25:44 GMT 2024 - 4.3K bytes - Click Count (0) -
