当我使用reactjs时，我从前端获取API请求当我尝试按价格过滤产品时，我收到意外错误：

• • axios 调用**

axios.get(`/api/v1/products?keyword=${keyword}&page=${currentPage}&price[lte]=${price[1]}&price[gte]=${price[0]}`)

• • 后端**在后端，我将get请求处理为

exports.getProducts =  (req, res, next) => {
  const resPerPage = 4;
  const productsCount = await Product.countDocuments();

  const apiFeatures = new APIFeatures(Product.find(), req.query)
    .search()
    .filter();

  let products = await apiFeatures.query;
  let filteredProductsCount = products.length;

  apiFeatures.pagination(resPerPage);
  products = await apiFeatures.query;

  res.status(200).json({
    success: true,
    productsCount,
    resPerPage,
    filteredProductsCount,
    products,
  });
};

我的APIFatures.js是

class APIFeatures {
  constructor(query, queryStr) {
    this.query = query;
    this.queryStr = queryStr;
  }
  search() {
    const keyword = this.queryStr.keyword
      ? {
          name: {
            $regex: this.queryStr.keyword,
            $options: 'i',
          },
        }
      : {};
    this.query = this.query.find({ ...keyword });
    return this;
  }
  filter() {
    const queryCopy = { ...this.queryStr };

    // removing fields from the query
    const removeFields = ['keyword', 'limit', 'page'];
    removeFields.forEach((el) => delete queryCopy[el]);

    //   advance filter for price, ratings etc
    let queryStr = JSON.stringify(queryCopy);
    queryStr = queryStr.replace(/\b(gt|gte|lt|lte)\b/g, (match) => `$${match}`);

    this.query = this.query.find(JSON.parse(queryStr));
    return this;
  }
  pagination(resPerPage) {
    const currentPage = Number(this.queryStr.page) || 1;
    const skip = resPerPage * (currentPage - 1);
    this.query = this.query.limit(resPerPage).skip(skip);
    return this;
  }
}
module.exports = APIFeatures;

但是当我从我的前端调度得到请求时，我得到了关于我的价格过滤器的错误

• • 错误**

"Query was already executed: Product.find({ price: { '$lte': 1000, '$gte': 1 } })"
