如何使用自定义对象编写graphql查询

type User {
  id: ID!
  name: String!
  email: String!
  posts: [Post!]!
}

type Post {
  id: ID!
  title: String!
  content: String!
  author: User!
}

type Query {
  user(id: ID!): User
  post(id: ID!): Post
}

const users = [
  { id: '1', name: 'John Doe', email: 'john@example.com', posts: ['1', '2'] },
  { id: '2', name: 'Jane Smith', email: 'jane@example.com', posts: ['3'] },
];

const posts = [
  { id: '1', title: 'GraphQL 101', content: 'Introduction to GraphQL', author: '1' },
  { id: '2', title: 'Advanced GraphQL', content: 'Advanced topics in GraphQL', author: '1' },
  { id: '3', title: 'GraphQL Schema Design', content: 'Best practices for designing GraphQL schemas', author: '2' },
];

const resolvers = {
  Query: {
    user: (parent, args) => users.find(user => user.id === args.id),
    post: (parent, args) => posts.find(post => post.id === args.id),
  },
  User: {
    posts: (parent) => posts.filter(post => post.author === parent.id),
  },
  Post: {
    author: (parent) => users.find(user => user.id === parent.author),
  },
};

query {
  user(id: "1") {
    id
    name
    email
    posts {
      id
      title
      content
    }
  }
}
