I almost have this working, I just can't seem to download the file when it comes up. What am I doing wrong here? When clicking the button "Download Sales Report" a CSV should download, by my console.log() never even fires off.
var casper = require('casper').create();
casper.start('http://www.waynecountyauditor.org/Reports.aspx?ActiveTab=Sales')
.waitForText("Accept")
.thenClick('#ctl00_ContentPlaceHolder1_btnDisclaimerAccept')
.waitForText("View Sales")
.thenClick('#ctl00_ContentPlaceHolder1_WeeklySales_fvSalesReport_btnViewSales')
.waitForText("Download Sales Report")
.thenClick(x('//*[@id="ctl00_blSearchLinks"]/li[4]/a'))
.wait(1000)
.on('page.resource.received', function(resource) {
console.log('here');
if (resource.stage !== "end") {
return;
}
if (resource.url.indexOf('results.csv') > -1) {
this.download(resource.url, 'D:\Jobs\Currency\testing\ExportData.csv');
}
});
casper.run();
I finally figured it out. Vaviloff had 99% of what I needed. I was just missing 2 post variables. Thanks for your help Vaviloff!

I finally got the answer after long time RD, we can use download node module for downloading the attachment as follows
const fs = require('fs');
const download = require('download');
download('http://unicorn.com/foo.pdf').then(data => {
fs.writeFileSync('dist/foo.pdf', data);
});`
