在Express中使用req.query与请求模块

Question

I am currently using Mikeal's request module in express. I am trying to get a bunch of data from two json urls and put them into a table. I want to be able to define two dates to use in the json url in req.query but I'm not too sure how. Right now, I'm able to define the dates in my terminal but I want to get rid of that. This is what I have so far.

var request = require('request);
var link = https://examplelink.json;
var args = process.argv.splice(2);
var date1 = args[0];
var date2 = args[1];
var express = require('express');

var app = express();
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');    

app.get('/', function(req, res) {
    request.get({url: link + date1, json: true}, function(err, body, a) {
        if (err) {
            return res.send(500);
        }
        request.get({url: link + date2, json: true}, function(err, body, b) {
            if (err) {
                 return res.send(500);
            }
            res.render('table' { a: a, b: b});
       });
}):

var number = 7000;
app.listen(number);
console.log("Listening at " + number);

This is a simplified version but I hope it gets the message across. I would like to modify this so that I don't have to define the dates with args and I can do it in the url.

Thanks so much

You can specify the date arguments as query string parameters in the URL such as http://localhost:7000?date1=2013-07-22&date2=2013-07-23 . To access these in express they will be req.query.date1 and req.query.date2 inside your app.get('/' handler function.
