I've updated that playground page with the actual URL of the API I'm using
- you'll see that the page comes back blank, but if you follow the link in
the browser, you get a page full of XML. So there must be something about
the data that the API is returning that XWiki doesn't like?
Agreed on using final releases - a full upgrade to 7.x is actually planned
soon. If I remember correctly, we got stuck on RC1 during the last
production upgrade cycle because there was some feature in 6.2 that we
really needed but the final release was still a few weeks out by our
deadline so we rolled the dice. Fortunately we haven't run into many issues
- which is probably why we're running behind on the upgrade :)

Maybe there was a problem specifically on 6.2RC1 (BTW better use some
final releases…:)). I’d recommend 6.4.5 for the 6.x cycle.

Page syntax is XWiki 2.1 and the velocity is wrapped. Sorry, I didn't
include the full code for simplicity's sake. Here's a minimal example cut
and pasted from the editor (only thing changed is the actual URL):
*******************************
{{velocity}}
#set($getURL = "https://www.example.com/api/example.mhtml?param=123")
$getURL
#set($content = $xwiki.getURLContent($getURL))
$content
{{/velocity}}
If I set $getURL to "https://google.com", it prints $content to the page.
With my API URL, I get nothing but the link in $getURL. But if I follow
that link, I get the expected XML page from the API, so I know the URL is
working correctly.
I figured it was because $content is XML from the API, and HTML from
google, but using $services.xml.parse on the response doesn't work either.
The strange part is that this is code that I haven't touched in quite some
time, and used to be working. The full code parses the XML response and
saves various elements to an HTML table on the page - but it doesn't appear
to be getting that far.

Hi Aaron,

XWiki 6.2RC1. I have some velocity code using
getURLContent() to access
an
external API that appears to not be working after
a server move, despite
working in the past.
Something like this used to work:
*****************************
#set($url = "https://www.example.com/api/example.mhtml?param=123")
#set($response = $xwiki.getURLContent($url))
#if ($response)
#set($tags = $services.xml.parse($response).getElementsByTagName('TAG'))
$tags.length
#end
*****************************
Now, $response appears to be empty (nothing appears when written to the
page). Going directly to the API URL returns properly formatted XML, so
I
know the API itself is working. And changing $url
to http://google.com
also
returns data.
Any ideas?
What is the syntax of your page? Are you sure it’s XWiki Syntax 2.0+ and
you’re wrapping the velocity content with the {{velocity}} macro for
example (you didn’t show it in your example).
$response is still there
Thanks
