如何在 Nodejs Mongodb 中设置最低价格最高价格参数，并从通过 postman 发布的这些查询中获取数据

Question

How to set min price max price parameters in Nodejs Mongodb, and get data from these queries posted through postman.

  if (req.query.max_price && req.query.max_price != "") {
      qry.price = { $lte: req.query.max_price };
  }

and

if (req.query.max_price && req.query.max_price != "") {
     qry.price = { $lte: req.query.max_price };
}

But it doesn't follow the parameters given like min_query

Answer 1

first of all, you must parse the query input to Int or Float. here is a sample of the code:

const max = parseInt(req.query.max, 10);
Models.Collection.find({price: {$lte: max}});
