## Base64 vs Files { #base64-vs-files }

Consider first if you can use [Request Files](../tutorial/request-files.md) for uploading binary data and [Custom Response - FileResponse](./custom-response.md#fileresponse--fileresponse-) for sending binary data, instead of encoding it in JSON.

JSON can only contain UTF-8 encoded strings, so it can't contain raw bytes.

These are the tasks that can be performed to manage the FastAPI repository by [team members](./fastapi-people.md#team).

/// tip

This section is useful only to a handful of people, team members with permissions to manage the repository. You can probably skip it. 😉

///

...so, you are a [team member of FastAPI](./fastapi-people.md#team)? Wow, you are so cool! 😎

## Спробуйте { #try-it }

Розмістіть код у файлі `main.py`, а потім запустіть ваш застосунок:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Відкрийте у браузері [http://127.0.0.1:8000](http://127.0.0.1:8000).

Ви побачите просту сторінку на кшталт:

A versatile option is the [OpenAPI Generator](https://openapi-generator.tech/), which supports **many programming languages** and can generate SDKs from your OpenAPI specification.

For **TypeScript clients**, [Hey API](https://heyapi.dev/) is a purpose-built solution, providing an optimized experience for the TypeScript ecosystem.

You can discover more SDK generators on [OpenAPI.Tools](https://openapi.tools/#sdk).

## 尝试一下 { #try-it }

将代码放在 `main.py`，然后运行你的应用程序：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

在浏览器中打开 [http://127.0.0.1:8000](http://127.0.0.1:8000)。

您将看到一个简单的页面，如下所示：

                                                                                aria-label="Close">
                                                                            <span aria-hidden="true">×</span>
                                                                        </button>
                                                                    </div>

But you can configure the **application server** to trust the *forwarded* headers sent by the **proxy**. If you are using FastAPI CLI, you can use the *CLI Option* `--forwarded-allow-ips` to tell it from which IPs it should trust those *forwarded* headers.
