# 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。🤓

Sie können <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a> im Docstring schreiben, es wird korrekt interpretiert und angezeigt (unter Berücksichtigung der Einrückung des Docstring).

That's why the current versions are still `0.x.x`, this reflects that each version could potentially have breaking changes. This follows the <a href="https://semver.org/" class="external-link" target="_blank">Semantic Versioning</a> conventions.

Вы можете использовать <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a> в строке документации, и он будет интерпретирован и отображён корректно (с учетом отступа в строке документации).

You can write <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a> in the docstring, it will be interpreted and displayed correctly (taking into account docstring indentation).

{* ../../docs_src/path_operation_configuration/tutorial004_py310.py hl[17:25] *}

Por eso las versiones actuales siguen siendo `0.x.x`, esto refleja que cada versión podría tener potencialmente cambios incompatibles. Esto sigue las convenciones de <a href="https://semver.org/" class="external-link" target="_blank">Semantic Versioning</a>.

from fastapi import FastAPI, Path, Query

          DEX_WEB_HTTP: "0.0.0.0:5557"

    strategy:
      # When ldap, etcd or openid vars are empty below, those external servers
      # are turned off - i.e. if ldap="", then ldap server is not enabled for
      # the tests.
      matrix:
        go-version: [1.24.x]
        ldap: ["", "localhost:389"]

So, the line:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

will not be executed.
