For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

```Python hl_lines="10  12-13"
{!../../../docs_src/middleware/tutorial001.py!}
```

## Other middlewares

Sie könnten beispielsweise einen benutzerdefinierten Header `X-Process-Time` hinzufügen, der die Zeit in Sekunden enthält, die benötigt wurde, um den Request zu verarbeiten und eine Response zu generieren:

```Python hl_lines="10  12-13"
{!../../../docs_src/middleware/tutorial001.py!}
```

## Andere Middlewares

(헤더같은) 요청 요구사항이나 하위-의존성을 선언할 수 있습니다:

=== "Python 3.9+"

    ```Python hl_lines="8  13"
    {!> ../../../docs_src/dependencies/tutorial006_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="7  12"
    {!> ../../../docs_src/dependencies/tutorial006_an.py!}
    ```

=== "Python 3.8 Annotated가 없는 경우"

    !!! tip "팁"
        가능하다면 `Annotated`가 달린 버전을 권장합니다.

    ```Python hl_lines="6  11"

```

<details markdown="1">
<summary>Oppure usa <code>async def</code>...</summary>

Se il tuo codice usa `async` / `await`, allora usa `async def`:

```Python hl_lines="7  12"
from fastapi import FastAPI
from typing import Optional

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

*경로 작동*을 받기 전 `request`와 함께 작동할 수 있는 코드를 추가할 수 있습니다.

그리고 `response` 또한 생성된 후 반환되기 전에 코드를 추가 할 수 있습니다.

예를 들어, 요청을 수행하고 응답을 생성하는데 까지 걸린 시간 값을 가지고 있는 `X-Process-Time` 같은 사용자 정의 헤더를 추가할 수 있습니다.

```Python hl_lines="10  12-13"
{!../../../docs_src/middleware/tutorial001.py!}
```

    return {"item_id": item_id, "q": q}
```

<summary>O usa <code>async def</code>...</summary>

Si tu código usa `async` / `await`, usa `async def`:

```Python hl_lines="7  12"
from fastapi import FastAPI
from typing import Union

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
