Open (function (error,client) {///database: Mongotest    if (error) throw error;    var collection = new MongoDB. Collection (client, ' user ');//table: User    Collection.find (function (error,cursor) {        Cursor.each (Error, DOC) {            if (doc) {                console.log ("Name:" +doc.name+ "Age:" +doc.age);            }        );});
