# Envoyer des fichiers { #request-files }

Vous pouvez définir des fichiers à téléverser par le client en utilisant `File`.

/// info

Pour recevoir des fichiers téléversés, installez d'abord [`python-multipart`](https://github.com/Kludex/python-multipart).

Assurez-vous de créer un [environnement virtuel](../virtual-environments.md), de l'activer, puis d'installer le paquet, par exemple :

```console
$ pip install python-multipart
```

# Archivos de Request { #request-files }

Puedes definir archivos que serán subidos por el cliente utilizando `File`.

/// info | Información

Para recibir archivos subidos, primero instala [`python-multipart`](https://github.com/Kludex/python-multipart).

Asegúrate de crear un [entorno virtual](../virtual-environments.md), activarlo y luego instalarlo, por ejemplo:

```console
$ pip install python-multipart
```

# 流式数据 { #stream-data }

如果你要流式传输可以结构化为 JSON 的数据，你应该[流式传输 JSON Lines](../tutorial/stream-json-lines.md)。

但如果你想流式传输纯二进制数据或字符串，可以按下面的方法操作。

/// info | 信息

自 FastAPI 0.134.0 起新增。

///

## 使用场景 { #use-cases }

如果你想流式传输纯字符串，例如直接来自某个 AI LLM 服务的输出，可以使用它。

你也可以用它来流式传输大型二进制文件，在读取的同时按块发送，无需一次性把所有内容读入内存。

你还可以用这种方式流式传输视频或音频，甚至可以在处理的同时生成并发送。

## 使用 `yield` 的 `StreamingResponse` { #a-streamingresponse-with-yield }
