node.js - Node MongoDB Native - filter by date/time -


in native mongodb, following limits full text search articles published in past 6 hours:

db.getcollection('articles').find({     $and: [{         $text: {             $search: 'stackoverflow'         }     }, {         $where: function() {             return date.now() - this.published.gettime() < (6 * 60 * 60 * 1000)         }     }] })...

the above not work on node.js node-mongodb-native - whole $where object ignored, doesn't throw error. there other way can limit query results based on time?

try creating datetime object prior using in query constructing new date value of current timestamp minus 6 hours follows:

var sixhours = 6 * 60 * 60 * 1000; /* ms */     sixhoursago = new date(new date().gettime() - sixhours);  db.getcollection('articles').find({     $text: { $search: 'stackoverflow'},     published: { $gte: sixhoursago  } })

or use momentjs library pretty handy when dealing dates, in particular subtract() method

var moment = require('moment'),     sixhoursago = moment().subtract(6, 'hours');

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver.
