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。

///

## 查询参数类型转换 { #query-parameter-type-conversion }

参数还可以声明为 `bool` 类型，FastAPI 会自动转换参数类型：

/// note

Notice that even though the `item` was declared the same way as before, it is now expected to be inside of the body with a key `item`.

///

**FastAPI** will do the automatic conversion from the request, so that the parameter `item` receives its specific content and the same for `user`.

It will perform the validation of the compound data, and will document it like that for the OpenAPI schema and automatic docs.

## Conversão dos tipos de parâmetros de consulta { #query-parameter-type-conversion }

Você também pode declarar tipos `bool`, e eles serão convertidos:

Nesse caso, se você for para:

```

// jsonFloat converts a float to string similar to Go stdlib formats json floats.
func jsonFloat(f float64) string {
	var tmp [32]byte
	dst := tmp[:0]

	// Convert as if by ES6 number to string conversion.
	// This matches most other JSON generators.
	// See golang.org/issue/6384 and golang.org/issue/14135.
	// Like fmt %g, but the exponent cutoffs are different
	// and exponents themselves are not padded to two digits.
