[JavaScript知识库]React中使用Apollo访问Hasura GraphiQL

Apollo官网的教程如下：

npm install @apollo/client graphql

在载入文件里如下操作

import {
  ApolloClient,
  InMemoryCache,
  ApolloProvider,
  useQuery,
  gql
} from "@apollo/client";

const client = new ApolloClient({
  uri: 'https://48p1r2roz4.sse.codesandbox.io',
  cache: new InMemoryCache()
});

client
  .query({
    query: gql`
      query GetRates {
        rates(currency: "USD") {
          currency
        }
      }
    `
  })
  .then(result => console.log(result));

会出现如下问题：

解决方案：

const client = new ApolloClient({
  uri: 'https://first-sculpin-26.hasura.app/v1/graphql',
  cache: new InMemoryCache(),
  headers: {
    "content-type": "application/json",
    "x-hasura-admin-secret":"your x-hasura-admin-secret" ,
  }
})
