!!! tip
    Note that we're using async/await with the new `AsyncClient` - the request is asynchronous.

!!! warning
    If your application relies on lifespan events, the `AsyncClient` won't trigger these events. To ensure they are triggered, use `LifespanManager` from <a href="https://github.com/florimondmanca/asgi-lifespan#usage" class="external-link" target="_blank">florimondmanca/asgi-lifespan</a>.

## Other Asynchronous Function Calls

Then, you try with the old programmer's friend, editor autocompletion.

You type the first parameter of the function, `first_name`, then a dot (`.`) and then hit `Ctrl+Space` to trigger the completion.

But, sadly, you get nothing useful:

### Add types

Let's modify a single line from the previous version.

# OpenAPI Callbacks

You could create an API with a *path operation* that could trigger a request to an *external API* created by someone else (probably the same developer that would be *using* your API).

## Зависимости для групп *операций пути*

And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:


```Python

```Python hl_lines="9  14"
{!../../../docs_src/dependencies/tutorial006.py!}
```

## 🔗 👪 *➡ 🛠️*

⏪, 🕐❔ 👂 🔃 ❔ 📊 🦏 🈸 ([🦏 🈸 - 💗 📁](../../tutorial/bigger-applications.md){.internal-link target=_blank}), 🎲 ⏮️ 💗 📁, 👆 🔜 💡 ❔ 📣 👁 `dependencies` 🔢 👪 *➡ 🛠️*.

## 🌐 🔗

    ```Python hl_lines="9  14"
    {!> ../../../docs_src/dependencies/tutorial006.py!}
    ```

## *경로 작동* 모음에 대한 의존성

나중에 여러 파일을 가지고 있을 수 있는 더 큰 애플리케이션을 구조화하는 법([더 큰 애플리케이션 - 여러 파일들](../../tutorial/bigger-applications.md){.internal-link target=_blank})을 읽을 때, *경로 작동* 모음에 대한 단일 `dependencies` 매개변수를 선언하는 법에 대해서 배우게 될 것입니다.

## 전역 의존성

```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app
```

### Applications plus larges

Si vous avez suivi la section sur la création d' [Applications avec plusieurs fichiers](../tutorial/bigger-applications.md){.internal-link target=_blank}, votre `Dockerfile` pourrait ressembler à ceci :

```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app/app
```

The response object will also have autocompletion:

<img src="/img/tutorial/generate-clients/image05.png">

## FastAPI App with Tags

In many cases your FastAPI app will be bigger, and you will probably use tags to separate different groups of *path operations*.

For example, you could have a section for **items** and another section for **users**, and they could be separated by tags:

RUN pip install --no-cache-dir --upgrade -r /app/requirements.txt

COPY ./app /app
```

### Большие приложения

Если вы успели ознакомиться с разделом [Приложения содержащие много файлов](../tutorial/bigger-applications.md){.internal-link target=_blank}, состоящие из множества файлов, Ваш Dockerfile может выглядеть так:

```Dockerfile hl_lines="7"
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.9
