Passing a URL in as path info, stops at "/", even when encoded

[Chris Shenton <Ch...@hq.nasa.gov>]

I'm working on a proxy-type application.  The app generates a page
with links pointing at my Turbine app and path info which specifies a
URL with the actual content to be retrieved. Like this, inside angle brackets:

  A HREF="http://palimpsest.it.hq.nasa.gov:8080/sna/servlet/Turbine/action/Proxy/url/http%3A%2F%2Fwww.google.com%2Fads%2F"

Initially, I just tacked on the normal URL but found that
ParameterParser was getting variable "url" (above) as just "http:".

I realized that Turbine was using the slashes in the full URL as
attribute/value separators.  So I used URLEncoder before affixing the
target URL to my path, as you see above.  But ParameterParser is still
seeing only the "http:" part, as if it's gratuitously decode()ing the
incoming URL string before parsing it.

Here's how the Proxy.doPerform is getting at the parameter, and then
putting it in my context for display:

  ParameterParser pp = data.getParameters();
  java.util.Enumeration keys = pp.keys();
  while (keys.hasMoreElements()) {
      String key = keys.nextElement().toString();
      data.addMessage(" key=`" + key + "'");
      data.addMessage(",val=`" + pp.getString(key) + "'");
  }

And the template emits it with a simple:

  $data.getMessage();

Which gets rendered, in part, as:

  key=`template',val=`Proxy.vm'
  key=`action',val=`Proxy'
  key=`url',val=`http:'
  key=`www.google.com',val=`ads'

Any suggestions how I get it to leave embedded slashes in an argument?
Thanks.

I had encoded the URL with URLEndcoder.encode() when I was using
PATH_INFO, but Turbine still saw the slashes, and therefore split
variables and values on those internal slashes.  I used your
QUERY_DATA suggestion, still with the URLEncoded URL to be safe, and
it works great.  Now full URLs look like:

http://palimpsest:8080/sna/servlet/Turbine/action/Proxy?url=http%3A%2F%2Fexample.com%2index.html

and the ParameterParser sees variable name "url" with the right value,
automatically URL-decoding it.

Many thanks.

Hi Chris,

Have you tried encoding the slashes in your QUERY_DATA arguments?  If this 
doesn't work, you will have to replace them with another character, and do a 
"find and replace" on the server.  Alternatively, you could write your own 
ParameterParser that leaves PATH_INFO intact.  Then you would have to use 
QUERY_DATA or POST for all the request parameters in your Turbine app.

Regards,

Beauty, eh! Works great.

Try using QUERY_DATA instead of PATH_INFO for the URL argument.

Hope that helps,
