我包含了数据库模式，并尝试使用Postman获取 *products * 数组中的产品。下面是基本URL：http：//localhost：5002/api/v1/store
此外，后端是好的，连接，所以http：//localhost：5002/api/v1/store？name=Apple将返回第一个文档。
谢谢
编辑：我添加了在端点API/v1/store上执行的代码
storeDao.js

let store;

export default class StoreDAO {
  static async injectDB(conn) {
    if (store) {
      return;
    }
    try {
      store = await conn.db(process.env.RESTREVIEWS_NS).collection("store");
    } catch (e) {
      console.error(
        `Unable to establish a collection handle in storeDAO: ${e}`
      );
    }
  }

  static async getStore({ filters = null, page = 0, storePerPage = 20 } = {}) {
    let query;
    if (filters) {
      if ("name" in filters) {
        query = { $text: { $search: filters["name"] } };
      } else if ("zipcode" in filters) {
        query = { zipcode: { $eq: filters["zipcode"] } };
      }
    }

    let cursor;

    try {
      cursor = await store.find(query);
    } catch (e) {
      console.error(`Unable to issue find command, ${e}`);
      return { storeList: [], totalNumStore: 0 };
    }

    const displayCursor = cursor.limit(storePerPage).skip(storePerPage * page);

    try {
      const storeList = await displayCursor.toArray();
      const totalNumStore = await store.countDocuments(query);

      return { storeList, totalNumStore };
    } catch (e) {
      console.error(
        `Unable to convert cursor to array or problem counting documents, ${e}`
      );
      return { storeList: [], totalNumStore: 0 };
    }
  }
}

store.controller.js

import storeDao from "../dao/storeDAO.js";

export default class StoreController {
  static async apiGetStore(req, res, next) {
    const storePerPage = req.query.storePerPage
      ? parseInt(req.query.storePerPage, 10)
      : 20;
    const page = req.query.page ? parseInt(req.query.page, 10) : 0;

    let filters = {};
    if (req.query.zipcode) {
      filters.zipcode = req.query.zipcode;
    } else if (req.query.name) {
      filters.name = req.query.name;
    }

    const { storeList, totalNumStore } = await storeDao.getStore({
      filters,
      page,
      storePerPage,
    });

    let response = {
      store: storeList,
      page: page,
      filters: filters,
      entries_per_page: storePerPage,
      total_results: totalNumStore,
    };
    res.json(response);
  }
}
