Can PhoneGap support CORS?

[Eugene Mirkin]

Anyone who ever tried using 3rd party REST services via AJAX may know
about the restrictions on cross-domain scripting. That is the browser
disallowing JS-originated HTTP JSON requests for fear of a variety of
unsound reasons. A common workaround is to implement CORS (cross-
origin resource sharing) headers. While that works well in the pc
domain, most mobile browsers disallow it.

Phonegap is in a unique position to help us all (us - all those trying
to build applications that call REST APIs from JS). Since every
Phonegap app comes with a native component, it would be really cool if
Phonegap offered JS AJAX tied to a Java/Obj-C native handler. I.e.
rather than doing AJAX through the browser and falling victim to its
restrictions, one could submit their requests through the native stack
which does not have the same limitation. What say, Phonegap?

PhoneGap for iOS, Android and BlackBerry use WebKit. WebKit supports CORS.

"WebKit: as announced on the WebGL mailing list, CORS support for
images and videos is now fully implemented"

http://enable-cors.org/

Most of the UI for PhoneGap (e.g. jQTouch, jQuery Mobile, Sencha
Touch, etc.) use AJAX-JSON to post/get data from web servers.

Hi Eugene, Noli,

In case the server you're pulling data from doesn't support CORS, it would be very easy to do what you describe through a Phonegap plugin (see for example the Twitter plugin for iOS where you pass a URL and parameters stored in a JS array and get a JSON string as output -- https://github.com/phonegap/phonegap-plugins/pull/595)

Also, in PhoneGap you can just XHR directly to remote servers and it
should "just work". Cross-domain policy does not apply to PhoneGap
(for a variety of reasons, basically because your app is essentially
running off the file:// URI on-device).

Please be aware that you will have to set up a whitelist for your apps
to access these external domains.
