# 表单模型

您可以使用 **Pydantic 模型**在 FastAPI 中声明**表单字段**。

/// info

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> 。

确保您创建、激活一个[虚拟环境](../virtual-environments.md){.internal-link target=_blank}后再安装。

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

///

/// note

自 FastAPI 版本 `0.113.0` 起支持此功能。🤓

## `PyJWT` installieren { #install-pyjwt }

Wir müssen `PyJWT` installieren, um die JWT-Tokens in Python zu generieren und zu verifizieren.

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und dann `pyjwt` installieren:

<div class="termy">

```console
$ pip install pyjwt
