Support use of ember-g-map from China

[arturalkaim]

The url https://maps.googleapis.com/maps/api/js is blocked in China and http://maps.google.cn/maps/api/js should be used instead.

https://developers.google.com/maps/documentation/javascript/localization#GoogleMapsChina

Is there a way to handle this? Or only gracefully handle the error without breaking everything?

Thank you!

I think the quickest fix would be to use the exclude: true option in config/environment.js and handle loading the google maps script yourself in your index.html. The best solution i can think of is to serve a different version of your index.html (with the google.cn script src) to users in China.

It'd be great if we could find a way to have the addon handle this, but I'm not sure there's a bullet-proof client-side solution for this problem. I'm open to suggestions though.

On my index.html I have:

  <script src="//maps.googleapis.com/maps/api/js" type="text/javascript"></script>
  /* Fallback for google maps api for China  */
  <script type="text/javascript">
    if (  typeof window.google == 'undefined' || typeof window.google.maps == 'undefined') {
      document.write(unescape('%3Cscript type="text/javascript" src="//maps.google.cn/maps/api/js" %3E%3C/script%3E'));
    }
  </script>

This way at least it's not breaking. This would also allow you to always load something in the plugin code.

But thanks! Your suggestion will probably fix my issue.

I added a note about this in the readme in PR #128 I will leave this issue open for now. I think the solution @arturalkaim shared is reasonable but may not be appropriate as a default behavior for the addon. I'd still like to solve this in the addon though.
