## ヘッダーの重複 { #duplicate-headers }

受信したヘッダーが重複することがあります。つまり、同じヘッダーで複数の値を持つということです。

これらの場合、型宣言でリストを使用して定義することができます。

重複したヘッダーのすべての値をPythonの`list`として受け取ることができます。

例えば、複数回出現する可能性のある`X-Token`のヘッダを定義するには、以下のように書くことができます:

{* ../../docs_src/header_params/tutorial003_an_py310.py hl[9] *}

その*path operation*と通信する際に、次のように2つのHTTPヘッダーを送信する場合:

```
X-Token: foo

### Deploy your app (optional)

You can optionally deploy your FastAPI app to [FastAPI Cloud](https://fastapicloud.com), go and join the waiting list if you haven't. 🚀

If you already have a **FastAPI Cloud** account (we invited you from the waiting list 😉), you can deploy your application with one command.

<div class="termy">

```console
$ fastapi deploy
