从外部站点下载XML

Question

I'm creating a web app (using phonegap) that needs to retrieve an xml document from an online site. How do I do this? From what i gather, AJAX will only work on relative url's due to some security restriction...

Answer 1

You can query a PHP script on your server using AJAX that returns the XML content using something like file_get_contents or PHP XML SimpleXML:

Answer 2

have you tried to work with JQuery ajax api? You will have to make the crossDomain option to true so that you can do a crossdomain request. Also, you will have to add the site to your white list domains in the PhoneGap plist file.

Answer 3

PhoneGap doesn't subject your code to the same-origin policy which prevents you from using AJAX cross-domain:

Q. I want to create an application for phonegap to access externally deployed web services via AJAX. How can i resolve the issue with the cross-domain security policy of XmlHttpRequest?

A. The cross-domain security policy does not affect PhoneGap applications. Since the html files are called by webkit with the file:// protocol, the security policy does not apply.

(in Android,you may grant android.permission.INTERNET to your app by edit the AndroidManifest.xml)
