Question

是否可以使用诸如graphql.js-https://github.com/f/graphql.js之类的非Apollo客户端连接到Apollo GraphQL服务器？

如果是这样，应该使用哪个端点？还是有另一种方法？

此操作失败，并显示HTTP 500服务器错误：

const graph = graphql('http://localhost:3013/graphql', {
        method: 'POST' // POST by default.
    });

    const res = graph(`query getQuestions {
        questions {
          id,
          question
        }
      }
    `);

    res().
        then((result) => console.log(result))
        .catch((err) => console.log(err));

当然，您可以使用任何GraphQL客户端，只要该客户端遵循GraphQL规范即可。

例如

server.ts：

import { ApolloServer, gql } from 'apollo-server';
import graphql from 'graphql.js';

const typeDefs = gql`
  type Query {
    _: String
  }
`;
const resolvers = {
  Query: {
    _: () => 'Hello',
  },
};
const server = new ApolloServer({
  typeDefs,
  resolvers,
});
server.listen().then(async ({ url }) => {
  console.log(`Apollo server is listening on ${url}graphql`);
  const graph = graphql(`${url}graphql`, { asJSON: true });
  const helloQuery = graph(`
    query {
      _
    }
  `);
  const actual = await helloQuery();
  console.log('actual: ', actual);
  server.stop();
});

输出：

Apollo server is listening on http://localhost:4000/graphql
actual:  { _: 'Hello' }

使用备用GraphQL客户端连接到Apollo服务器
