# FastAPI CLI { #fastapi-cli }

**FastAPI CLI** is a command line program that you can use to serve your FastAPI app, manage your FastAPI project, and more.

When you install FastAPI (e.g. with `pip install "fastapi[standard]"`), it includes a package called `fastapi-cli`, this package provides the `fastapi` command in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console

## Установка `websockets` { #install-websockets }

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md){.internal-link target=_blank}, активировали его и установили `websockets` (библиотека Python, упрощающая работу с протоколом "WebSocket"):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

Переконайтеся, що Ви створили [віртуальне середовище](../virtual-environments.md){.internal-link target=_blank}, активували його, а потім встановили бібліотеку, наприклад:

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

///

## Імпорт `File` та `Form`

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[3] *}

## Оголошення параметрів `File` та `Form`

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md){.internal-link target=_blank}, активировали его, а затем установили пакет, например:

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

# 表单数据

接收的不是 JSON，而是表单字段时，要使用 `Form`。

/// info | 说明

要使用表单，需预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如，`pip install python-multipart`。

## 导入 `Form`

从 `fastapi` 导入 `Form`：

{* ../../docs_src/request_forms/tutorial001.py hl[1] *}

## 定义 `Form` 参数

创建表单（`Form`）参数的方式与 `Body` 和 `Query` 一样：
