For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:

{* ../../docs_src/app_testing/tutorial002_py39.py hl[27:31] *}

/// note

# 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:

{* ../../docs_src/request_forms/tutorial001.py hl[1] *}

## `Form`のパラメータの定義

`Body`や`Query`の場合と同じようにフォームパラメータを作成します:

# Cuerpo - Actualizaciones { #body-updates }

## Actualización reemplazando con `PUT` { #update-replacing-with-put }

Para actualizar un ítem puedes utilizar la operación de <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a>.

import me.champeau.gradle.japicmp.JApiCmpWorkerAction
import me.champeau.gradle.japicmp.report.RichReportData

class EnrichedReportRenderer extends GroovyReportRenderer {
    private static acceptedChangesRegex = ~/<a href="(.+)">accepted-public-api-changes.json<\/a>/

    @Override
    void render(File htmlReportFile, RichReportData data) {
        super.render(htmlReportFile, enrichReport(data))
    }

    /**

{* ../../docs_src/middleware/tutorial001.py hl[8:9,11,14] *}

/// tip

请记住可以 <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">用'X-' 前缀</a>添加专有自定义请求头.

///

The `status_code` parameter receives a number with the HTTP status code.

/// info

`status_code` can alternatively also receive an `IntEnum`, such as Python's <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

///

It will:

* Return that status code in the response.
