Um `TestClient` zu verwenden, installieren Sie zunächst <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

Erstellen Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank}, aktivieren Sie sie und installieren Sie es dann, z. B.:

```console
$ pip install httpx
```

///

Importieren Sie `TestClient`.

    public String available;

    /** The permissions required to access documents from this configuration. */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String permissions;

    /** The virtual hosts associated with this file configuration. */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String virtualHosts;

    /** The sort order for this configuration (required, 0 to 2147483647). */

* parsing (noun): парсинг
* origin (in web development): origin (add `источник` if clarification is needed)
* include: включать (add `в себя` if it's appropriate, or use `содержать` as an alternative)
* virtual environment: виртуальное окружение
* framework: фреймворк
* path paremeter: path-параметр
* path (as in URL path): путь
* form (as in HTML form): форма
* media type: тип содержимого (or `медиа-тип`)
* request: HTTP-запрос

Esta información será útil al aprender sobre [Entornos Virtuales](virtual-environments.md){.internal-link target=_blank}.

## Conclusión { #conclusion }

Con esto deberías tener una comprensión básica de qué son las **variables de entorno** y cómo usarlas en Python.

    @Size(max = 5)
    public String available;

    /** Access permissions for documents from this data source */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String permissions;

    /** Virtual hosts where this configuration applies */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String virtualHosts;

# 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。🤓

///

## 表单的 Pydantic 模型

In the end, the ultimate objective is to be able to **serve your API clients** in a way that is **secure**, to **avoid disruptions**, and to use the **compute resources** (for example remote servers/virtual machines) as efficiently as possible. 🚀

Diese Informationen werden nützlich sein, wenn Sie über [Virtuelle Umgebungen](virtual-environments.md){.internal-link target=_blank} lernen.

## Fazit { #conclusion }

Mit diesem Wissen sollten Sie ein grundlegendes Verständnis davon haben, was **Umgebungsvariablen** sind und wie man sie in Python verwendet.

        .build()

    executor = newVirtualThreadPerTaskExecutor()

    // Capture non-deterministic but probable sysout warnings of pinned threads
    // https://docs.oracle.com/en/java/javase/21/core/virtual-threads.html
    System.setOut(PrintStream(capturedOut))
  }

  @AfterEach
  fun checkForPinning() {
    assertThat(capturedOut.toString()).isEmpty()
  }

FastAPI에서 **Pydantic 모델**을 이용하여 **폼 필드**를 선언할 수 있습니다.

/// info | 정보

폼(Form)을 사용하려면, 먼저 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>를 설치하세요.

[가상 환경](../virtual-environments.md){.internal-link target=_blank}을 생성하고 활성화한 다음, 아래와 같이 설치할 수 있습니다:

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

///

/// note | 참고

이 기능은 FastAPI 버전 `0.113.0` 이후부터 지원됩니다. 🤓
