To use `EmailStr`, first install <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install email-validator
```

or with:

```console
$ pip install "pydantic[email]"

/// info | Informação

Para usar `EmailStr`, primeiro instale <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ative-o e instale-o, por exemplo:

```console
$ pip install email-validator
```

ou com:

```console
$ pip install "pydantic[email]"
```

## Instalar o `SQLModel` { #install-sqlmodel }

Primeiro, certifique-se de criar seu [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e, em seguida, instalar o `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

При установке FastAPI он поставляется с продакшн‑сервером Uvicorn, и вы можете запустить его командой `fastapi run`.

Но вы также можете установить ASGI‑сервер вручную.

Создайте [виртуальное окружение](../virtual-environments.md){.internal-link target=_blank}, активируйте его и затем установите серверное приложение.

Например, чтобы установить Uvicorn:

<div class="termy">

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

labels.max_access_count=Max Access Count
labels.number_of_thread=Number of Threads
labels.interval_time=Interval
labels.millisec=msec
labels.permissions=Permissions
labels.virtual_hosts=Virtual Hosts
labels.virtual_host=Virtual Host
labels.label_type=Label
labels.file_crawling_button_create=Create
labels.file_crawling_button_create_job=Create New Job
labels.web_crawling_configuration=Web Crawling

系统会在 `C:\opt\custompython\bin\python` 中**找到** `python` 程序并运行它。

这和输入以下命令大致等价：

<div class="termy">

```console
$ C:\opt\custompython\bin\python
```

</div>

当学习[虚拟环境](virtual-environments.md)时，这些信息将会很有用。

## 结论

通过这个教程，你应该对**环境变量**是什么以及如何在 Python 中使用它们有了基本的了解。

## Abhängigkeiten installieren { #install-dependencies }

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und `jinja2` installieren:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

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

    /**
     * Virtual host names for this web configuration.
     */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String virtualHosts;

    /**
     * The sort order for this web configuration.
     */

系統會在 `C:\opt\custompython\bin\python` 中**找到** `python` 程式並執行它。

這大致等同於輸入以下指令：

<div class="termy">

```console
$ C:\opt\custompython\bin\python
```

</div>

當學習[虛擬環境](virtual-environments.md)時，這些資訊將會很有用。

## 結論

透過這個教學，你應該對**環境變數**是什麼以及如何在 Python 中使用它們有了基本的了解。

# 폼 데이터

JSON 대신 폼 필드를 받아야 하는 경우 `Form`을 사용할 수 있습니다.

/// info | 정보

폼을 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
```

## `Form` 임포트하기

`fastapi`에서 `Form`을 임포트합니다:
