# フォームデータ

JSONの代わりにフィールドを受け取る場合は、`Form`を使用します。

/// info | "情報"

フォームを使うためには、まず<a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

たとえば、`pip install python-multipart`のように。

## `Form`のインポート

`fastapi`から`Form`をインポートします:

```Python hl_lines="1"
{!../../docs_src/request_forms/tutorial001.py!}
```

## `Form`のパラメータの定義

    You shouldn't use this class directly.

See [Architecture decisions records](standards) for the list of ADRs.
Be aware these are very technical descriptions of the decisions, and you might find the documentation below more useful as an introduction to the internals of Gradle.

## Platform architecture

Gradle is arranged into several coarse-grained components called "platforms".

    @Test
    void testMirrorWithMirrorOfPatternContainingANegationIsNotSelected() {
        ArtifactRepository repository = new DefaultArtifactRepository("snapshots.repo", "http://whatever", null);
        String pattern = "external:*, !snapshots.repo";
        assertFalse(DefaultMirrorSelector.matchPattern(repository, pattern));
    }

## Details about the `Request` object

As **FastAPI** is actually **Starlette** underneath, with a layer of several tools on top, you can use Starlette's <a href="https://www.starlette.io/requests/" class="external-link" target="_blank">`Request`</a> object directly when you need to.

# CORS (Cross-Origin Resource Sharing)

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS or "Cross-Origin Resource Sharing"</a> refers to the situations when a frontend running in a browser has JavaScript code that communicates with a backend, and the backend is in a different "origin" than the frontend.

## Origin

  // external refers to a global metric that is not associated
  // with any Kubernetes object. It allows autoscaling based on information
  // coming from components running outside of cluster
  // (for example length of queue in cloud messaging service, or
  // QPS from loadbalancer running outside of cluster).
  // +optional
  optional ExternalMetricSource external = 5;

`"json_schema_extra"`를 생성된 JSON 스키마에서 보여주고 싶은 별도의 데이터와 `examples`를 포함하는 `dict`으로 설정할 수 있습니다.
