## Импорт `Header` { #import-header }

Сперва импортируйте `Header`:

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

## Объявление параметров `Header` { #declare-header-parameters }

Затем объявите параметры заголовка, используя ту же структуру, что и с `Path`, `Query` и `Cookie`.

## Позначити застарілою *операцію шляху* - OpenAPI { #documentation-deprecate-a-path-operation-openapi }

Щоб позначити *операцію шляху* як застарілу і показати це в інтерфейсі документації, прочитайте документацію [Навчальний посібник - Налаштування операції шляху - Позначення як застаріле](../tutorial/path-operation-configuration.md#deprecate-a-path-operation).

  ** since Maven 3.6.1, inheritance can avoid appending any path to parent value by setting model attribute value to
  <<<false>>> for each url:
  <<<project/@child.project.url.inherit.append.path>>>,
  <<<project/distributionManagement/site/@child.site.url.inherit.append.path>>>,
  <<<project/scm/@child.scm.connection.inherit.append.path>>>,
  <<<project/scm/@child.scm.developerConnection.inherit.append.path>>> and

These are the special functions that you can put in *path operation function* parameters or dependency functions with `Annotated` to get data from the request.

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python
from fastapi import Body, Cookie, File, Form, Header, Path, Query
```

::: fastapi.Query

        private volatile long lastAccessTime;

        public LeaseEntry(Smb2LeaseKey key, String path, int state) {
            this.leaseKey = key;
            this.path = path;
            this.leaseState = state;
            this.createTime = System.currentTimeMillis();

在某些類型的應用程式中，你可能想為整個應用程式新增依賴。

類似於你可以在[路徑操作（path operation）的裝飾器中新增 `dependencies`](dependencies-in-path-operation-decorators.md) 的方式，你也可以把它們加到 `FastAPI` 應用程式上。

在這種情況下，它們會套用到應用程式中的所有路徑操作：

{* ../../docs_src/dependencies/tutorial012_an_py310.py hl[17] *}

而且，在[將 `dependencies` 新增到路徑操作裝飾器](dependencies-in-path-operation-decorators.md) 那一節中的所有概念依然適用，只是這裡是套用到整個應用中的所有路徑操作。
