如何设置API平台react-admin graphql堆栈？

Question

我正在设置 Api平台（已启用graphql）服务器和 react-admin 客户端。 我在api平台（名称为Domain）上创建资源。如果我查询GraphQL Playground应用程序，我会得到预期的结果。 在使用ra-data-graphql-simple软件包安装react-admin之后，客户端尝试连接，并且客户端返回错误“未知资源域。请确保已在服务器端模式上声明了该错误”

这是我的App.js代码

import React, { Component } from 'react';
import { Admin, Resource, Delete } from 'react-admin';
import buildGraphQLProvider from 'ra-data-graphql-simple';
import myBuildQuery from './dataProvider';
import { DomainShow, DomainEdit, DomainCreate, DomainList } from './domain';
class App extends Component {
  constructor() {
      super();
      this.state = { dataProvider: null };
  }
  componentDidMount() {
        const introspectionOptions = {
            include: ['Domains', 'Purchases'],
        };

      buildGraphQLProvider({ 
            //buildQuery: myBuildQuery, 
            clientOptions: { uri: 'http://127.0.0.1:8000/api/graphql' },
            introspection: introspectionOptions

        })
        .then(dataProvider => this.setState({ dataProvider }));
  }

  render() {
      const { dataProvider } = this.state;

      if (!dataProvider) {
          return <div>Loading</div>;
      }

      return (
          <Admin dataProvider={dataProvider}>
              <Resource name="domains" list={ DomainList } create={ DomainCreate } show={ DomainShow } edit={ DomainEdit } title="Domains"/>
          </Admin>
      );
  }
}

export default App;
