Can't read local xml file with xmlhttp request

[EthanS94]

It seems loading this locally with file:///path/to/index.html broke sometime recently. Javascript(with XMLHttpRequest is not allowed to query ColorMaps.xml if it is a local file. It still works fine when sending requests to an http server.

The error I get is:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///path/to/ColorMaps.xml. (Reason: CORS request not http).

Ethan, I also have this as an issue in cinemascience/cinema_explorer#16.
Hack fix: I can get around this by going to about:config in my browser and changing privacy.file_unique_origin to false in Firefox.

Or yes, do the http server -- from Jon Woodring

I’m instead running a simple http server instead out of the cinema explorer directory.
Python 2:
$ python -m SimpleHTTPServer
Python 3:
$ python -m http.server

Thanks, Terry. That works for me. Once I add this to some documentation on the website, I'll close this issue
