Hi!
From my experience: is very very tough...
It is much easier to make this kind of request in ThingWorx Platform and then bind result in ThingWorx Studio.
I tried many things and the result is:
- There is a lot of problems with HTTP & HTTPS mixes. I am not sure, but it seems to that if you are connected to the HTTPS Experience Service, you cannot make HTTP calls, and same in other way. Weird.
- Then you server must be configured to not use Cross Origin Check, and CORS must be configured as well.
- AngularJS $http was not working for us. We used XMLHttpRequest() object.
Hope it is good start. Highly recommend to use ThingWorx Platform as a proxy for your RESTs. It is much easier.
Best,
Adam
