現在你可以匯入並使用用戶端程式碼。大致看起來會像這樣，你會發現方法有自動完成：

<img src="/img/tutorial/generate-clients/image02.png">

你也會對要送出的有效載荷獲得自動完成：

<img src="/img/tutorial/generate-clients/image03.png">

/// tip

注意 `name` 與 `price` 的自動完成，這是由 FastAPI 應用中的 `Item` 模型所定義。

你在送出的資料上也會看到行內錯誤：

回應物件同樣有自動完成：

Dennoch können wir das zu erwartende Schema für den Requestbody deklarieren.

### Benutzerdefinierter OpenAPI-Content-Type { #custom-openapi-content-type }

Mit demselben Trick könnten Sie ein Pydantic-Modell verwenden, um das JSON-Schema zu definieren, das dann im benutzerdefinierten Abschnitt des OpenAPI-Schemas für die *Pfadoperation* enthalten ist.

Pydantic 덕분에 표준 Python 타입을 사용해 본문을 선언합니다.

```Python hl_lines="2  7-10 23-25"
