我正在设置一个react-admin应用程序，该应用程序需要使用graphql提供程序与Hasura Service连接。为此，我需要为提供者传递终结点“ / v1 / graphql”和带有选择子字段的查询。像这样：

query MyQuery {
  account_customers {
    customer_id
    email
    given_name
  }
}

我尝试使用Hasura Provider（https://github.com/hasura/ra-data-hasura/），但申请将转到“ / v1 / query”，但找不到如何更改它。也无法弄清楚如何发送带有子字段的自定义查询。

我还尝试使用ra-data-graphql-simple提供程序来覆盖查询  获得带有子字段的资源。

/providers/myProvider.js

import buildGraphQLProvider,{ buildQuery } from 'ra-data-graphql-simple';
import gql from 'graphql-tag';


const myBuildQuery = introspection => (fetchType,resource,params) => {
    const builtQuery = buildQuery(introspection)(fetchType,params);

    if (resource === 'account_customers' && fetchType === 'GET_LIST') {
        return {
            // Use the default query variables and parseResponse
            ...builtQuery,// Override the query
            query: gql`
                query ($id: ID!) {
                    account_customers {
                        customer_id
                        email
                        name
                      }
                }`,};
    }

    return builtQuery;
}

export default buildGraphQLProvider({ buildQuery: myBuildQuery })

App.js

import buildGraphQLProvider from './providers/myProvider.js';


class App extends Component {

  constructor() {
    super();
    this.state = { dataProvider: null };
  }

  componentDidmount() {
      buildGraphQLProvider({ clientOptions: { uri: 'http://localhost:8080/v1/graphql' }})
          .then(dataProvider => this.setState({ dataProvider }));
  }

  render() {
    const { dataProvider } = this.state;
    return (
      <div classname="App">
        <Admin dataProvider={dataProvider} >
          <Resource name="account_customers" list={ListGuesser} />
        </Admin>
      </div>
    );
  }
}

export default App;

但是我得到了错误：

“未知资源account_customers。请确保已在服务器端架构上声明它。已知资源为”
