# 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:

import jakarta.validation.ConstraintValidator;
import jakarta.validation.ConstraintValidatorContext;

/**
 * Validator implementation for the CronExpression constraint.
 */
public class CronExpressionValidator implements ConstraintValidator<CronExpression, String> {

    /**
     * Default constructor.
     */
    public CronExpressionValidator() {
        // Empty constructor
    }

/**
 * Form for uploading bad word files to the Fess search engine.
 * This form is used in the admin interface to upload bad word dictionary files
 * that contain words to be filtered from search results.
 */
public class UploadForm {

    /**
     * The multipart file containing bad words to be uploaded.
     * This file should contain a list of words that will be filtered from search results.
     */
    @Required
