我有返回此结果的代码：

// Use this hook to manipulate incoming or outgoing data.
// For more information on hooks, see: http://docs.feathersjs.com/api/hooks.html

module.exports = function (options = {}) { // eslint-disable-line no-unused-vars
    return async context => {
      // Get `app`, `method`, `params` and `result` from the hook context
      const { app, method, result, params } = context;

      // Make sure that we always have a list of users either by wrapping
      // a single message into an array or by getting the `data` from the `find` method's result
      const interacts = method === 'find' ? result.data : [ result ];

      // console.log(users);

      // Asynchronously get user object from each message's `userId`
      // and add it to the message
      await Promise.all(interacts.map(async interact => {

        // await Promise.all(user.map(async interacts => {
          // Also pass the original `params` to the service call
          // so that it has the same information available (e.g. who is requesting it)
          // bots.botId = await app.service('bots').get(bots.botId, params);
          interact.display = await app.service('messages').find({
             query: {
              to: "ijHTUNeSbSQNICOC",
              from: "8Tp5maaTePqiD3DI",
              $limit: 1,
              $sort: {
                createdAt: -1
              }
             }
          });
        // }));

      }));
      console.log(context);

      // Best practice: hooks should always return the context
      return context;
    };
  };

返回这个结果：

    },

如何只留下数据这个..：

"userId": "Z5DO1Gx2YpXLTRBb",
  "interactUser": "fNEgNVk6yh3msVa8",
  "_id": "T3ekz58yNDacS5o2",
  "display": 
       {
        "text": "nome1",
        "from": "8Tp5maaTePqiD3DI",
        "to": "ijHTUNeSbSQNICOC",
        "createdAt": 1554757301176,
        "_id": "o2vkUj7suYzhEZk7"
  }

“userId”：“Z5DO1Gx2YpXLTRBb”，“interactUser”：“fNEgNVk6yh3msVa8”，“_id”：“T3ekz58yNDacS5o2”，“display”：{“text”：“nome1”，“from”：“8Tp5maaTePqiD3DI”，“to”：“ ijHTUNeSbSQNICOC”，“createdAt”：1554757301176，“_id”：“o2vkUj7suYzhEZk7”}

如果有任何方法，或者更确切地说格式化查询返回的结果

你有这些结果的原因是因为pagination。禁用分页只会返回数据。

您可以创建自己的钩子来处理如果请求将禁用分页的查询。

好消息是，有一个包可以解决你的问题，feahters-hooks-common。

您想要的确切挂钩记录在 ( disablepagination ) 中。
