# 查询参数和字符串校验 { #query-parameters-and-string-validations }

**FastAPI** 允许你为参数声明额外的信息和校验。

让我们以下面的应用为例：

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

查询参数 `q` 的类型为 `str | None`，这意味着它是 `str` 类型，但也可以是 `None`。其默认值确实为 `None`，所以 FastAPI 会知道它不是必填的。

/// note | 注意

FastAPI 会因为默认值 `= None` 而知道 `q` 的值不是必填的。

将类型标注为 `str | None` 能让你的编辑器提供更好的辅助和错误检测。

Você pode personalizar essa função. Ela recebe uma `APIRoute` e retorna uma string.

Por exemplo, aqui está usando a primeira tag (Você provavelmente terá apenas uma tag) e o nome da *operação de rota* (o nome da função).
