Es gibt zwei Hauptunterschiede zu einer normalen *Pfadoperation*:

* Es muss kein tatsächlicher Code vorhanden sein, da Ihre Anwendung diesen Code niemals aufruft. Sie wird nur zur Dokumentation der *externen API* verwendet. Die Funktion könnte also einfach `pass` enthalten.

**FastAPI** 不強制任何特定的意義。

這裡的資訊作為一個指南，而不是要求。

例如，當使用 GraphQL 時，你通常只使用 `POST` 操作。

///

### 第四步：定義 **路徑操作函式**

這是我們的「**路徑操作函式**」：

* **path**: 是 `/`.
* **operation**: 是 `get`.
* **function**: 是裝飾器下面的函式（在 `@app.get("/")` 下面）。

{* ../../docs_src/first_steps/tutorial001.py h1[7] *}

這就是一個 Python 函式。

它將會在 **FastAPI** 收到一個請求時被呼叫，使用 `GET` 操作。

在這種情況下，它是一個 `async` 函式。

## Cuerpos de listas puras { #bodies-of-pure-lists }

Si el valor superior del cuerpo JSON que esperas es un `array` JSON (una `list` en Python), puedes declarar el tipo en el parámetro de la función, al igual que en los modelos Pydantic:

```Python
images: list[Image]
```

como en:
