First, CORS is tricky, a PITA, so don't feel bad if you are having
problems.
JSONP is a good, easy solution for GET ting data. It does not work well
for PUT, POST, DELETE
Somewhere I've seen some angular examples with JSONP - test if you are
receiving data - then in what format the data is in (try showing what
the response looks like it console.log or even alert) to see what form
the data is coming in - you might have to strip off something or
reformat the response in your controller.
One issue with CORS and Angular is if the server requires a "pre-flight"
request. In short your app needs to send a notice, then receive a
response, then connect. Someone did post some angular code how to do
this - try to google it.
sorry, have no experience with using a promise so can't help you with
that - try 1 step at a time, get the data, see what you get, then try to
add the promise in and track down where the error is.

Attempting to make a http call to weather underground api loosely

<http://www.ng-newsletter.com/posts/chrome-apps-on-angular.html>.
This is my code <https://gist.github.com/telagraphic/9105662> which
contains two calls to the same api call, one using $http with CORS
http header configuration and another call using jsonp that receives
the json payload but the view won't display it.
I've read that CORS is the preferably approach over JSONP, but I'm a
little clueless as to why I'm getting the No
'Access-Control-Allow-Origin' as I've added the proper http header
code in my angular config code.
My secondary approach with JSONP will console.log the response object
but won't display on my view.
Any assistance that will aid my comprehension of these approaches is
greatly appreciated.
I think my local host server doesn't accept the response from weather
ground for my http call due to missing the 'Access-Control-Allow-Origin'.
No idea of what do if that is the case...
