[Kde-pim] KFacebook Problem

[tang yu]

Hi,
    I checkout the KFacebook source code from  "svn co svn://
anonsvn.kde.org/home/kde/trunk/playground/pim/kfacebook".  After make and
make install, I added the kfacebook plasmoid to desktop. But it didn't work
well, what I get is just *a blank white widget* in the desktop.
    The network was working well, and there was no place to configure the
user-name or network stuff.

    I tried to figure out what's going on, I opened the KIO debug info.
below is some situation:

    1. Use plasmaenginexploier to test plasma-engine-facebook:
*plasmaengineexplorer(16704) KFacebook::Session: Found no session or expired
session

      2. I add "addMetaData("content-type", "Content-Type:

Content http error.
     *3.* *I used firefox to directly access* **
http://api.facebook.com/restserver.php?sig=92383319ddbbbad3566fe17833f4d96d&api_key=0d4781a23c2c20fd1717900cb31a8a12&method=facebook.auth.createToken&v=1.0,
*and received the right response.
*
     *I checked the *http://wiki.developers.facebook.com/index.php/API . *and
there is a note says :* *If you manually form your HTTP POST requests to
Facebook, you must include the request data in the POST body. In addition,
you should include a Content-Type: header of
application/x-www-form-urlencoded.  So, do we need to update the kfacebook?
      Could anyone tell me how to make it work?

Thanks very much.
Br.
