2、mongodb查询语句:
db.getCollection('regioncodes').aggregate([ {$unwind:"$children"}, {$unwind:"$children.children"}, { $match: { "children.children.id":"073103" } }, {$group:{ _id:{cityId:"$children.id",cityName:"$children.text",hesinNo:"$children.children.id",hesinName:"$children.children.text"} } } ]);
