Mongo Db，如何查询参数中哪里是带数组的对象。我想 return 基于下面示例查询参数的结果。 array 中的 year 还包括 model ， mileage 等。我们将如何在 mongo 中做到这一点？我想 return 基于下面过滤器的数据。
代码
exports.list = function (req, res) {
let request = req.query.filters || req.query
let pageNo = parseInt(req.query.page || 1)
let size = parseInt(req.query.pageSize || 10)
let query_pagination = {}
let query = {}
query_pagination.skip = size * (pageNo - 1)
query_pagination.limit = size
query.Year = { $in: request.year }
query.Model = { $in: request.model }
query.Mileage = { $in: request.mileage }
query.PriceRange = { $in: request.priceRange }
query.BodyStyle = { $in: request.bodyStyle }
console.log("query", query)
Vehicle.model.find().exec(function(err, vehicle) {
if(err || !vehicle) {
res.json({
message: err
})
}
return res.status(200).send({
message: "success",
data: vehicle
})
})
}
}
查询参数
{

Model: ['Edge', 'Eco Sports', 'Escape'],
Mileage: ['1-1000'],
PriceRange: [',000-,000'],
BodyStyle: ['Convertible', '2dr Car', '4dr Car']
