使用MongoDB和NodeJS查询特定日期 [英] Query for a specific date with MongoDB and NodeJS

问题描述

在MongoDB集合中，我有一个Date对象，它记录事件的日期和时间.我正在尝试根据特定日期进行查询，并忽略时间，即向我显示今天的所有事件.

Within a MongoDB Collection I have a Date object that records both the date and time of an event. I am trying to query based on a specific date and to ignore the time i.e. show me all events for today.

Model.js

var EventSchema = new Schema({
eventName        : String,
eventDate        : Date, 
eventLocation    : String,
eventLocationGeo : String,
eventCreator     : ObjectId
});

我的主要 app.js 正在寻找Unix时间戳格式的日期.

My main app.js is looking for the date to come across in Unix Timestamp format.

//Get Events based on Unix Time Stamp Date
app.get('/events/date/:date', passportConf.isAuthenticated, function(req, res){
var user = req.user._id;
var date = req.params.date;
console.log('date - ' + date);
eventController.getEventsByDate(user, date, req, res);
});

典型的REST呼叫

    http://localhost/events/date/1410764400

大多数参考文章使用$ gte和$ lt进行引用，但没有在哪里提及如何减少时间，因此我的查询最终基于完整的日期和时间拉了24小时.

Most of the reference articles reference using the $gte and $lt but no where does it mention how to strip off the time so my queries end up pulling 24 hours based on the full Date AND time.

推荐答案

我建议使用moment.unix(req.params.date).startOf('day').toDate()和moment.unix(req.params.date).endOf('day').toDate() -of/"rel =" nofollow> moment.js库，它非常有用.

I would recommend using moment.unix(req.params.date).startOf('day').toDate() and moment.unix(req.params.date).endOf('day').toDate() from the moment.js library, which is phenomenally useful.

仅使用ECMAScript日期，您可以执行以下操作:

With just ECMAScript Date, you can do:

var start = new Date(req.params.date);
start.setHours(0);
start.setMinutes(0);
start.setSeconds(0);
start.setMilliseconds(0);
