Graphql 响应不是来自 Apollo 客户端查询

Question

在我的本地 http://localhost:3000/graphql 查询中的工作方式如下...

但是当我通过 apollo 客户端查询时，它的响应为空

import {InMemoryCache, gql, ApolloClient, HttpLink} from 'apollo-boost';
const cache = new InMemoryCache();
const client = new ApolloClient({
  cache,
  link: new HttpLink({
    uri: 'http://localhost:3000/graphql',
    credentials: 'same-origin',
  }),
  },
});

client
  .query({
    query: gql`
      {
        brands {
          _id
        }
      }
    `,
  })
  .then(data => console.log(data))
  .catch(error => {
    // its coming in this section
    console.log(error);
  });

不知道我错过了什么。感谢任何帮助谢谢！！！

以下是我尝试从前端查询时的屏幕截图

Answer 1

通过添加 app.js

解决

global.XMLHttpRequest = global.originalXMLHttpRequest || global.XMLHttpRequest;
global.FormData = global.originalFormData || global.FormData;

if (window.FETCH_SUPPORT) {
  window.FETCH_SUPPORT.blob = false;
} else {
  global.Blob = global.originalBlob || global.Blob;
  global.FileReader = global.originalFileReader || global.FileReader;
}
