רק גרדנו את קצה הקרחון, אבל כבר יש לכם רעיון של איך הכל עובד.

נסו לשנות את השורה:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...מ:

```Python
        ... "item_name": item.name ...
```

...ל:

```Python
        ... "item_price": item.price ...
```

...וראו איך העורך שלכם משלים את המאפיינים ויודע את הטיפוסים שלהם:

🥇 ✍ 🆕 `APIRouter` 👈 🔜 🔌 1️⃣ ⚖️ 🌅 ⏲.

```Python hl_lines="3  25"
{!../../docs_src/openapi_callbacks/tutorial001.py!}
```

### ✍ ⏲ *➡ 🛠️*

✍ ⏲ *➡ 🛠️* ⚙️ 🎏 `APIRouter` 👆 ✍ 🔛.

⚫️ 🔜 👀 💖 😐 FastAPI *➡ 🛠️*:

* ⚫️ 🔜 🎲 ✔️ 📄 💪 ⚫️ 🔜 📨, ✅ `body: InvoiceEvent`.
*  & ⚫️ 💪 ✔️ 📄 📨 ⚫️ 🔜 📨, ✅ `response_model=InvoiceEventReceived`.

```Python hl_lines="16-18  21-22  28-32"

总之，ASGI 中间件是类，并把 ASGI 应用作为第一个参数。

因此，有些第三方 ASGI 中间件的文档推荐以如下方式使用中间件：

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

但 FastAPI（实际上是 Starlette）提供了一种更简单的方式，能让内部中间件在处理服务器错误的同时，还能让自定义异常处理器正常运作。

为此，要使用 `app.add_middleware()` （与 CORS 中的示例一样）。

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

## `Depends()`

Dependencies are handled mainly with the special function `Depends()` that takes a callable.

Here is the reference for it and its parameters.

You can import it directly from `fastapi`:

```python
from fastapi import Depends
```

::: fastapi.Depends

## `Security()`

For many scenarios, you can handle security (authorization, authentication, etc.) with dependencies, using `Depends()`.

FROM python:3.9

RUN pip install httpx PyGithub "pydantic==2.0.2" pydantic-settings "pyyaml>=5.3.1,<6.0.0"

COPY ./app /app

```Python hl_lines="15 16 17 18 19 20 21 22 23"
{!../../docs_src/schema_extra_example/tutorial001.py!}
```

その追加情報はそのまま出力され、JSON Schemaに追加されます。

## `Field`の追加引数

後述する`Field`、`Path`、`Query`、`Body`などでは、任意の引数を関数に渡すことでJSON Schemaの追加情報を宣言することもできます:

```Python hl_lines="4 10 11 12 13"
{!../../docs_src/schema_extra_example/tutorial002.py!}
```

Aber FastAPI unterstützt auf die gleiche Weise auch die Verwendung von <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a>:

```Python hl_lines="1  7-12  19-20"
{!../../docs_src/dataclasses/tutorial001.py!}
```

## `Header` 임포트

먼저 `Header`를 임포트합니다:

```Python hl_lines="3"
{!../../docs_src/header_params/tutorial001.py!}
```

## `Header` 매개변수 선언

`Path`, `Query` 그리고 `Cookie`를 사용한 동일한 구조를 이용하여 헤더 매개변수를 선언합니다.

첫 번째 값은 기본값이며, 추가 검증이나 어노테이션 매개변수 모두 전달할 수 있습니다:

```Python hl_lines="9"
{!../../docs_src/header_params/tutorial001.py!}
```
