/**
     * The (expected) path to the artifact on the local filesystem. An artifact which has this property set is assumed
     * to be not present in any regular repository and likewise has no artifact descriptor. Artifact resolution will
     * verify the path and resolve the artifact if the path actually denotes an existing file. If the path isn't valid,

## Імпорт `Header` { #import-header }

Спочатку імпортуйте `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Оголошення параметрів `Header` { #declare-header-parameters }

Потім оголосіть параметри заголовків, використовуючи ту ж структуру, що й для `Path`, `Query` та `Cookie`.

		e, ok := d.Cache[path.Key()]
		if !ok {
			return
		}
		if len(e.Children) == 0 {
			return
		}
		sz := d.sizeRecursive(path.Key())
		leaves = append(leaves, struct {
			objects uint64
			path    dataUsageHash
		}{objects: sz.Objects, path: path})
		for ch := range e.Children {
			add(dataUsageHash(ch))
		}
	}

	// Add path recursively.
	add(path)
	sort.Slice(leaves, func(i, j int) bool {

* `"function"`: dependency'yi request'i işleyen *path operation function* çalışmadan önce başlat, *path operation function* bittikten sonra bitir, ancak response client'a geri gönderilmeden **önce** sonlandır. Yani dependency fonksiyonu, *path operation **function***'ın **etrafında** çalıştırılır.

你可以用與定義 `Query`、`Path`、`Cookie` 參數相同的方式來定義 Header 參數。

## 匯入 `Header` { #import-header }

先匯入 `Header`：

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## 宣告 `Header` 參數 { #declare-header-parameters }

接著使用與 `Path`、`Query`、`Cookie` 相同的結構來宣告標頭參數。

你可以設定預設值，以及所有額外的驗證或註解參數：

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

/// note | 注意

## `PATH` Environment Variable { #path-environment-variable }

There is a **special** environment variable called **`PATH`** that is used by the operating systems (Linux, macOS, Windows) to find programs to run.

## Variable d'environnement `PATH` { #path-environment-variable }

Il existe une **variable d'environnement spéciale** appelée **`PATH`** qui est utilisée par les systèmes d'exploitation (Linux, macOS, Windows) pour trouver les programmes à exécuter.

## Déclarer les attributs du modèle { #declare-model-attributes }

Vous pouvez ensuite utiliser `Field` avec des attributs de modèle :

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` fonctionne de la même manière que `Query`, `Path` et `Body`, il dispose des mêmes paramètres, etc.
