Question

我是相当新的graphQL。我的要求是在发送查询时，graphQL应该返回如下的JSON响应

{
    user: '$',
    name: 'Josh',
    age: '30'
}

我尝试了以下方式，但没有达到结果。

var express = require('express');
var graphqlHTTP = require('express-graphql');
var { buildSchema } = require('graphql');

var schema = buildSchema(`
  type Query {
    user: String!
    }
`);


// JSON
var json = {
    user: '$',
    name: 'Josh',
    age: '30'
};

var root = {
    user: () => {
    return json;
    }

};

var app = express();
app.use('/graphql', graphqlHTTP({
  schema: schema,
  rootValue: root,
  graphiql: true,
}));
app.listen(4000);
console.log('Running a GraphQL API server at localhost:4000/graphql');

有人可以指导我要去哪里哪里

谢谢。

我通过以下方法实现：

var express = require('express');
var graphqlHTTP = require('express-graphql');
var { buildSchema } = require('graphql');
const { GraphQLJSON, GraphQLJSONObject } = require('graphql-type-json');

var schema = buildSchema(`
scalar JSON
  type Query {
    getObject: JSON
    }
`);

var root = {
    JSON: GraphQLJSON,

    getObject: () => {
    return {
        name: "jshua",
        age: "30",
        place: "china",
        gender: "Male"
    }
    }

};

var app = express();
app.use('/graphql', graphqlHTTP({
  schema: schema,
  rootValue: root,
  graphiql: true,
}));
app.listen(4000);
console.log('Running a GraphQL API server at localhost:4000/graphql');
