如何將 object 鍵和值推送到數組

Question

我需要將鍵值對推送到新數組，並且應該構建 mongodb $match 查詢。

const queryFormat = (payload) => {
    delete payload.userEventId
    var query = {}
     var res = []
    for(key in payload) {
        if(typeof(payload[key])) {
       res.push({ [key]: payload[key] })
        }
        else {
            res.push({"$in" :{ [key]: payload[key] }})
        }
    }
    console.log(res[3])
    query['$match'] = {"$and" :res}
    console.log(query)    
}


const payload = {
    id :1,
    name : 'Alfred',
    location : 'moon',
    values : [{name: 'u',age:9}]
}
queryFormat(payload)

預計 output

{"$match":{"$and":[{id:1},{name:"Alfred"},{location:"moon"},{"values":{"$in":[{name:"u"},{age: 9}]} }]}}

output 我得到了

{"$match":{"$and":[{id:1},{name:"Alfred"},{location:"moon"},{"values":{"$in":[{name:"u",age: 9}]} }]}}

怎么處理 謝謝！！

目前您將密鑰指定為"key"

使用[]指定需要key的值作為key

 const queryFormat = (payload) => { delete payload.userEventId var query = {} var res = [] for(key in payload) { res.push({ [key]: payload[key] }) } query['$match'] = {"$and":res} console.log(query) } const payload = { id:1, name: 'Alfred', location: 'moon' } queryFormat(payload)
