Se você utiliza uma versão anterior, ocorrerão erros ao tentar utilizar `Annotated`.

Certifique-se de [Atualizar a versão do FastAPI](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} para pelo menos 0.95.1 antes de usar `Annotated`.

## Zusammenfassung { #recap }

It's easy to use a file as a request body.

=== ":material-language-kotlin: Kotlin"
    ```kotlin
      private val client = OkHttpClient()

      fun run() {
        val file = File("README.md")

        val request = Request.Builder()
            .url("https://api.github.com/markdown/raw")
            .post(file.asRequestBody(MEDIA_TYPE_MARKDOWN))
            .build()

### 更主流的 Python

全部都基于标准的 **Python 3.6 类型**声明（感谢 Pydantic ）。没有新的语法需要学习。只需要标准的 Python 。

如果你需要2分钟来学习如何使用 Python 类型（即使你不使用 FastAPI ），看看这个简短的教程：[Python Types](python-types.md){.internal-link target=_blank}。

编写带有类型标注的标准 Python：

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function

Still, in both situations, chances are that **FastAPI** will [still be faster](index.md#performance){.internal-link target=_blank} than (or at least comparable to) your previous framework.

### Dependencies { #dependencies }

Read more about sections `cluster_id`, `client_id` on [NATS documentation](https://github.com/nats-io/nats-streaming-server/blob/master/README.md). Section `maxPubAcksInflight` is explained [here](https://github.com/nats-io/stan.go#publisher-rate-limiting).

### Step 2: Enable NATS bucket notification using MinIO client

## Вернуть `Response` напрямую { #return-a-response-directly }

Вы также можете добавить HTTP-заголовки, когда возвращаете `Response` напрямую.

Создайте ответ, как описано в [Вернуть Response напрямую](response-directly.md){.internal-link target=_blank}, и передайте заголовки как дополнительный параметр:

{* ../../docs_src/response_headers/tutorial001_py39.py hl[10:12] *}

## Установка FastAPI { #install-fastapi }

Первый шаг — установить FastAPI.

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md){.internal-link target=_blank}, активировали его, и затем **установите FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>
