* データ処理:
    * たとえば、時間のかかる処理を必要とするファイル受信時には、「Accepted」(HTTP 202) のレスポンスを返し、バックグラウンドで処理できます。

## `BackgroundTasks` の使用 { #using-backgroundtasks }

まず初めに、`BackgroundTasks` をインポートし、`BackgroundTasks` の型宣言と共に、*path operation function* のパラメーターを定義します:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[1,13] *}

**FastAPI** は、`BackgroundTasks` 型のオブジェクトを作成し、そのパラメーターに渡します。

## タスク関数の作成 { #create-a-task-function }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[3] *}
ここで、`app`変数が`FastAPI`クラスの「インスタンス」になります。

これが、すべてのAPIを作成するための主要なポイントになります。

### Step 3: *path operation*を作成 { #step-3-create-a-path-operation }

#### パス { #path }

ここでの「パス」とは、最初の`/`から始まるURLの最後の部分を指します。

したがって、次のようなURLでは:

```
https://example.com/items/foo
```

...パスは次のようになります:

```
/items/foo
```

import okhttp3.internal.publicsuffix.ResourcePublicSuffixList.Companion.PUBLIC_SUFFIX_RESOURCE
import okio.BufferedSink
import okio.ByteString
import okio.ByteString.Companion.encodeUtf8
import okio.FileSystem
import okio.Path
import okio.Path.Companion.toPath
import okio.buffer

 * transforms the file into an efficient format used by OkHttp.

Template içinde `url_for()` da kullanabilirsiniz; argüman olarak, *path operation function*'ınızın kullandığı argümanların aynısını alır.

Dolayısıyla şu bölüm:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...*path operation function* olan `read_item(id=id)` tarafından handle edilecek URL'nin aynısına bir link üretir.

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[12] *}

Bu durumda, ek parametreleri ve alt-dependency'leri kontrol etmek için **FastAPI**'nin kullanacağı şey bu `__call__` olacaktır; ayrıca daha sonra *path operation function* içindeki parametreye bir değer geçmek için çağrılacak olan da budur.
