需要包含选项参数来配置json数据

import { fetchUtils } from 'react-admin';



const fetchJson = (url, options = {}) => {
    if (!options.headers) {
        options.headers = new Headers({ Accept: 'application/json' });
    } 
    return fetchUtils.fetchJson(url, options);
}

<Admin dataProvider={restProvider(dataProvider, fetchJson) }>
