/// info | Bilgi

Formları kullanmak için öncelikle <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> paketini indirmeniz gerekmektedir.

Örneğin `pip install python-multipart`.

///

## `Form` Sınıfını Projenize Dahil Edin

`Form` sınıfını `fastapi`'den projenize dahil edin:

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

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。🤓

///

## 表单的 Pydantic 模型

您只需声明一个 **Pydantic 模型**，其中包含您希望接收的**表单字段**，然后将参数声明为 `Form` :

///

//// tab | `pip`

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

////

//// tab | `uv`

Wenn Sie <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a> haben:

<div class="termy">

```console
$ uv pip install "fastapi[standard]"
---> 100%
```

</div>

////

Wenn Sie die `standard` optionalen Abhängigkeiten nicht einschließen möchten, können Sie mit `pip install fastapi` statt `pip install "fastapi[standard]"` installieren.

### Ohne `fastapi-cloud-cli` { #without-fastapi-cloud-cli }

Wenn Sie FastAPI mit den Standardabhängigkeiten, aber ohne das `fastapi-cloud-cli` installieren möchten, können Sie mit `pip install "fastapi[standard-no-fastapi-cloud-cli]"` installieren.

[virtual environment](../virtual-environments.md){.internal-link target=_blank} 를 만들고, 활성화 시킨 뒤에 설치하세요. 예시:

```console
$ pip install httpx
```

`TestClient` 를 임포트하세요.

**FastAPI** 어플리케이션을 전달하여 `TestClient` 를 만드세요.

이름이 `test_` 로 시작하는 함수를 만드세요(`pytest` 의 표준적인 관례입니다).

`httpx` 를 사용하는 것과 같은 방식으로 `TestClient` 객체를 사용하세요.

    for (queue in TaskRunner.INSTANCE.activeQueues()) {
      // We wait at most 1 second, so we don't ever turn multiple lost threads into
      // a test timeout failure.
      val waitTime = (entryTime + 1_000_000_000L - System.nanoTime())
      if (!queue.idleLatch().await(waitTime, TimeUnit.NANOSECONDS)) {
        TaskRunner.INSTANCE.withLock {
          TaskRunner.INSTANCE.cancelAll()
        }
