Uploading Files to Rackspace Cloud Files Using

Problem

Rackspace's officially supported python sdk is Pyrax - unfortunately it doesn't work with python3. There is the alternative apache module called libcloud but that is tricky to get working on windows.

Solution

Rackspace has a publically available api that can be used to manually send requests to your cloud files. All it requires is an existing container, a username, and an api key

To do this we will issue an initial request to rackspace with our credentials. Rackspace will then issue us a temporary token, and a list of services and urls to communicate with. We will pull our token and the cloudfiles services from this response and grab the url for our containers region (ie: DFW). Combine that url with our container and desired filename and we have the url we will upload our file to.

Setup the headers with our temporary token and content type and open the file we wish to send.
