I need to post result with Ajax, but the API I'm posting to uses 302 redirect to display results. Ajax won't follow the redirect, so I can never get my data. I just get a null response.

I can do a casper.open() and then it will at least post and follow to get results, but I don't want to navigate off page to get this result.

Any suggestions?

According to the question Why browser do not follow redirects using XMLHTTPRequest and CORS? this may be related to the problem with a cross-domain request and preflight checks.

The solution would be to run CasperJS with the --web-security=false option which PhantomJS provides:

casperjs --web-security=false script.js

Another possibility is to open a new tab/window. A casper instance manages only one main page (and multiple popups or child windows). If you're not in the test environment of CasperJS, then you can create a second casper instance and navigate to the other page. My answer here provides a drop-in solution for this with a usage example.

  • I have tried with web-security=false set but still getting null. It works perfectly in PH 1.98 but 2.0 is where it seems to have issues. Not sure if its a bug or what. – David James Schlaegel Aug 14 '15 at 01:20
