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.

You probably won't need to use it directly in your code.

But in case you needed it for an advanced scenario, you can add custom headers:

例如，要安装 Uvicorn，可以运行以下命令：

<div class="termy">

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

---> 100%
```

</div>

类似的流程也适用于任何其他 ASGI 服务器程序。

/// tip

通过添加 `standard` 选项，Uvicorn 将安装并使用一些推荐的额外依赖项。

其中包括 `uvloop`，这是 `asyncio` 的高性能替代方案，能够显著提升并发性能。

当您使用 `pip install "fastapi[standard]"` 安装 FastAPI 时，实际上也会安装 `uvicorn[standard]`。

## 运行服务器程序

[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:

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

## `Form` 매개변수 정의하기

/// info | 정보

이를 사용하려면 `orjson`을 설치해야합니다. 예: `pip install orjson`.

///

### `UJSONResponse`

<a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>을 사용한 또 다른 JSON 응답 형식입니다.

/// info | 정보

이 응답을 사용하려면 `ujson`을 설치해야합니다. 예: 'pip install ujson`.

///

/// warning | 경고

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

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

///

## Importar `Form` { #import-form }

Importar `Form` desde `fastapi`:

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

		;;
	esac
}

assert_check_golang_env() {
	if ! which go >/dev/null 2>&1; then
		echo "Cannot find go binary in your PATH configuration, please refer to Go installation document at https://golang.org/doc/install"
		exit 1
	fi

	installed_go_version=$(go version | sed 's/^.* go\([0-9.]*\).*$/\1/')
	if ! check_minimum_version "${GO_VERSION}" "${installed_go_version}"; then

하지만 필요한 경우 사용할 수 있습니다. 🤓

예외를 처리하고(또는 추가로 다른 `HTTPException`을 발생시키기 위해) 사용할 수 있는 또 다른 방법은 [사용자 정의 예외 처리기](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}를 생성하는 것 입니다.
