使用Nodejs将ArrayList的值与MongoDB进行比较

Question

我是Mongo的新手并尝试将ArrayList值与mongoDB进行比较，结果我想要匹配值列表。

让我解释一下。我有一个带有一个文档的集合。

db.contact.find().pretty(){
"_id" : ObjectId("5718ae778310b8eb61aed7b0"),
"contacts" : [
        {
                "name" : "Sunny",
                "phone" : "9417702107"
        },
        {
                "name" : "Sukhpal",
                "phone" : "9015719419"
        },
        {
                "name" : "anurag",
                "phone" : "9988776655"
        },
        {
                "name" : "vivek",
                "phone" : "8826565107"
        }
]}

这是我的Json with Array List，我将使用HTTPs：

{
"contacts":[
     {
         "name":"anurag",
         "phone":"9988776655"
     },
     {
         "name":"Gurwinder",
         "phone":"9015566789"
     }
]}

所以现在我不知道如何查询以及如何在mongo中循环播放数组。这是我的Node.js Mongoos代码：

exportcontact = function(req, res, next)
{
var response = {};
    Contacts.find({},function(err,data){
    // Mongo command to fetch all data from collection.
        if(err) {
            response = {"error" : true,"message" : "Error fetching data"};
        } 
        else if(!data)
            {
               response = {"error" : true,"message" : "No Record Found"};
            }
        else 
        {
            var contactlist = req.body.contacts;

             //************ DON'T KNOW WHAT TO DO HERE***************//
              response = {"List":     };

        }
        res.json(response);
    });
};

请帮忙。
