我正在尝试将 react-admin 与 hasura 适配器一起使用。当我尝试使用杂物时，错误

The response to 'GET_LIST' must be like { data: ... }, but the received response does not have a 'data' key.

身份验证工作正常，但我看不到任何查询“associado”数据的请求。仅启动 AUTH_CHECK 请求，没有针对“associado”表的 graphql 请求。在没有任何请求的情况下抛出错误。怎么了？

CRUD associado 的文件：

import React from 'react';
import { List, Datagrid, TextField, Show, SimpleShowLayout, DateField } from 'react-admin';

export function AssociadoList(props) {
    return (
        <List {...props}>
            <Datagrid>
                <TextField source="nome" />
                <DateField source="data_aniversario" />
                {/*<ReferenceField label="Endereço" source="enderecoId" reference="enderecos">
                <TextField source="bairro" />
                <TextField source="bairro" />
            </ReferenceField>*/}
            </Datagrid>
        </List>
    )
};

export function AssociadoShow(props) {
    return (
        <Show {...props}>
            <SimpleShowLayout>
                <TextField source="nome" />
                <DateField source="data_aniversario" />
            </SimpleShowLayout>
        </Show>
    )
};

身份验证提供者：

import { AUTH_LOGIN, AUTH_LOGOUT, AUTH_ERROR, AUTH_CHECK } from 'react-admin';
import graphql from './graphqlClient';
import Cookies from 'universal-cookie';
import { GraphQLClient } from 'graphql-request';

const cookies = new Cookies();

const LOGIN = `
    mutation($username:String!, $password:String!){
        login(username: $username, password: $password){
            token
        }
    }
`;
const ME = `
    query {
        me {
            username
        }
    }
`;

export default (type, params) => {

    if (type === AUTH_LOGIN) {
        const { username, password } = params;
        return graphql.request(LOGIN, { username, password }).then(data => {
            const token = data.login.token;
            cookies.set("authToken", token, { path: "/", sameSite: "strict" });
        });
    }
    if (type === AUTH_LOGOUT) {
        cookies.remove("authToken", { path: "/", sameSite: "strict" });
        return Promise.resolve();
    }
    if (type === AUTH_ERROR) {
        const graphqlauth = new GraphQLClient(process.env.REACT_APP_HASURA_ENDPOINT, {
            headers: {
                authorization: 'Bearer ' + cookies.get('authToken'),
            },
        })
        return graphqlauth.request(ME).then(data => { return (data.me.username) ? Promise.resolve() : Promise.reject(); }).catch(e => {
            cookies.remove("authToken", { path: "/", sameSite: "strict" });

        });

    }
    if (type === AUTH_CHECK) {
        return cookies.get('authToken') ? Promise.resolve() : Promise.reject();
    }
    return Promise.resolve();
};

和 App.js；

import React from 'react';
import { Admin, Resource } from 'react-admin';
import Dashboard from './Dashboard';
import hasuraDataProvider from 'ra-data-hasura';
import authProvider from './authProvider';
import Cookies from 'universal-cookie';
import { AssociadoList, AssociadoShow } from "./Associado";
import portugueseMessages from 'ra-language-portuguese'


const dataProvider = function () {

  const cookies = new Cookies();
  const dataProvider = hasuraDataProvider(process.env.REACT_APP_HASURA_URL, { "content-type": "application/json", "Authorization": "Bearer " + cookies.get("AuthToken") });
  return dataProvider;
}
const messages = {
  'pt': portugueseMessages,
};
const i18nProvider = locale => messages[locale];
function App() {
  return (
    <Admin
      dataProvider={dataProvider}
      authProvider={authProvider}
      dashboard={Dashboard}
      locale="pt" i18nProvider={i18nProvider}
    >
      <Resource name="adear.associado" list={AssociadoList} options={{ label: 'Associado' }} show={AssociadoShow} />
    </Admin>
  );
}

export default App;

这是我的 package.json

{
  "name": "dashboard",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "graphql-request": "^1.8.2",
    "ra-data-hasura": "^0.0.6",

    ]
  }
}

我的看法是您的自定义 dataProvider 有一个小问题。

您正在尝试增强 hasura 数据提供程序，但这样做会引入一个小错误。

import React from 'react';
import { Admin, Resource } from 'react-admin';
import Dashboard from './Dashboard';
import hasuraDataProvider from 'ra-data-hasura';
import authProvider from './authProvider';
import Cookies from 'universal-cookie';
import { AssociadoList, AssociadoShow } from "./Associado";
import portugueseMessages from 'ra-language-portuguese'


const dataProvider = function () {
  const cookies = new Cookies();
  // hasuraDataProvider is a factory, which returns a function
  const dataProvider = hasuraDataProvider(process.env.REACT_APP_HASURA_URL, { "content-type": "application/json", "Authorization": "Bearer " + cookies.get("AuthToken") });
  return dataProvider; // Here you are returning the real dataprovider
}

const messages = {
  'pt': portugueseMessages,
};

const i18nProvider = locale => messages[locale];

function App() {
  return (
    <Admin
      {/* dataProvider is a function which returns the hasura dataProvider, but React Admin expects to get your function results instead! */}
      dataProvider={dataProvider}
      authProvider={authProvider}
      dashboard={Dashboard}
      locale="pt" i18nProvider={i18nProvider}
    >
      <Resource name="adear.associado" list={AssociadoList} options={{ label: 'Associado' }} show={AssociadoShow} />
    </Admin>
  );
}

export default App;

恕我直言，修复就像在将道具传递给管理员时调用 dataProvider 函数一样简单。

-    dataProvider={dataProvider}
+    dataProvider={dataProvider()}

我找到了答案。为了使工作正常，您需要在 dataProvider 函数包装器中将授权令牌作为参数传递，并且使用 react-cookie，您可以使用状态和 React Hooks 的所有功能。这就像魔术：

import React from 'react';
import { Admin, Resource } from 'react-admin';
import Dashboard from './Dashboard';
import hasuraDataProvider from 'ra-data-hasura';
import authProvider from './authProvider';
import {useCookies} from "react-cookie";
import { AssociadoList, AssociadoShow } from "./Associado";
import portugueseMessages from 'ra-language-portuguese'


const dataProvider = function (authToken) {
  const dataProvider = hasuraDataProvider("http://localhost:8080", { "content-type": "application/json", "Authorization": "Bearer " +  authToken});
  return dataProvider;
}
const messages = {
  'pt': portugueseMessages,
};
const i18nProvider = locale => messages[locale];
function App() {
  const [cookies] = useCookies(['authToken']);
  return (
    <Admin
      dataProvider={dataProvider(cookies.authToken)}
      authProvider={authProvider}
      dashboard={Dashboard}
      locale="pt" i18nProvider={i18nProvider}
    >
      <Resource name="adear.associado" list={AssociadoList} options={{ label: 'Associado' }} show={AssociadoShow} />
    </Admin>
  );
}

export default App;
