## 声明 `Header` 参数 { #declare-header-parameters }

然后，使用和 `Path`、`Query`、`Cookie` 一样的结构定义 header 参数。

第一个值是默认值，还可以传递所有验证参数或注释参数：

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[9] *}

/// note | 技术细节

`Header` 是 `Path`、`Query`、`Cookie` 的**兄弟类**，都继承自共用的 `Param` 类。

注意，从 `fastapi` 导入的 `Query`、`Path`、`Header` 等对象，实际上是返回特殊类的函数。

///

/// info | 信息

必须使用 `Header` 声明 header 参数，否则该参数会被解释为查询参数。

}

// hashOrder - hashes input key to return consistent
// hashed integer slice. Returned integer order is salted
// with an input key. This results in consistent order.
// NOTE: collisions are fine, we are not looking for uniqueness
// in the slices returned.
func hashOrder(key string, cardinality int) []int {
	if cardinality <= 0 {
		// Returns an empty int slice for cardinality < 0.
		return nil
	}

要声明表单请求体，必须显式使用 `Form`，否则这些参数会被当作查询参数或请求体（JSON）参数。

///

## 关于 "表单字段" { #about-form-fields }

HTML 表单（`<form></form>`）向服务器发送数据时通常会对数据使用一种“特殊”的编码方式，这与 JSON 不同。

**FastAPI** 会确保从正确的位置读取这些数据，而不是从 JSON 中读取。

/// note | 技术细节

表单数据通常使用“媒体类型” `application/x-www-form-urlencoded` 进行编码。

但当表单包含文件时，会编码为 `multipart/form-data`。你将在下一章阅读如何处理文件。

The build cache has anonymous read access, so you don't need to authenticate in order to use it. You can use a different build cache node by specifying `-Ddevelocity.edge.discovery=false -DcacheNode=us` for a build cache node in the US or `-Ddevelocity.edge.discovery=false -DcacheNode=au` for a build cache node in Australia.
