如何在react-admin中使用getOne传递额外的数据？

import { fetchUtils } from 'react-admin';

const apiUrl = 'https://api.example.com'; // 替换为实际的API地址

const customDataProvider = {
    ...defaultDataProvider, // 默认的数据提供者

    getOne: (resource, params) => {
        const { id, extraData } = params;

        const url = `${apiUrl}/${resource}/${id}`;

        const options = {
            headers: new Headers({
                Accept: 'application/json',
            }),
        };

        return fetchUtils.fetchJson(url, options)
            .then(({ json }) => ({
                data: {
                    ...json,
                    extraData, // 将额外的数据添加到返回结果中
                },
            }));
    },
};

export default customDataProvider;

import React from 'react';
import { Admin, Resource } from 'react-admin';
import customDataProvider from './customDataProvider';

const App = () => (
    <Admin dataProvider={customDataProvider}>
        {/* 定义资源和页面 */}
    </Admin>
);

export default App;

import React from 'react';
import { Edit, SimpleForm, TextInput, FormDataConsumer } from 'react-admin';

const PostEdit = (props) => (
    <Edit {...props}>
        <SimpleForm>
            <TextInput source="title" />
            {/* 获取额外的数据 */}
            <FormDataConsumer>
                {({ formData }) => (
                    <TextInput source="extraData" defaultValue={formData.extraData} />
                )}
            </FormDataConsumer>
        </SimpleForm>
    </Edit>
);

export default PostEdit;
