如何使用apollo服务器对graphQl中的数据进行排序？

type Query {
  users(sortField: String): [User]
}

type User {
  id: ID
  name: String
  age: Int
}

const resolvers = {
  Query: {
    users: (_, { sortField }) => {
      let sortedUsers = [...users]; // 假设users是一个用户列表
      if (sortField) {
        sortedUsers.sort((a, b) => {
          if (a[sortField] < b[sortField]) return -1;
          if (a[sortField] > b[sortField]) return 1;
          return 0;
        });
      }
      return sortedUsers;
    }
  }
};

const { ApolloServer, gql } = require('apollo-server');

const typeDefs = gql`
  type Query {
    users(sortField: String): [User]
  }

  type User {
    id: ID
    name: String
    age: Int
  }
`;

const resolvers = {
  Query: {
    users: (_, { sortField }) => {
      let sortedUsers = [...users]; // 假设users是一个用户列表
      if (sortField) {
        sortedUsers.sort((a, b) => {
          if (a[sortField] < b[sortField]) return -1;
          if (a[sortField] > b[sortField]) return 1;
          return 0;
        });
      }
      return sortedUsers;
    }
  }
};

const server = new ApolloServer({ typeDefs, resolvers });

server.listen().then(({ url }) => {
  console.log(`Apollo server is running at ${url}`);
});

query {
  users(sortField: "age") {
    id
    name
    age
  }
}
