Hi,everybody i am a novice in building myspace application....

am using the code listed below.... 

$myspace = new MySpaceAPI($key,$secret);

echo $user = $_GET["opensocial_viewer_id"],"*";

$smarty->assign("viewer_id",$user);

$result = $myspace->get_user($user);

echo $result['displayname'];

I have curl extension enabled in my server,do i need to use pear instead?

am using php official library,can anyone help me out,am getting an errror like this:

" 'Exception' with message '401 401Invalid digital signature for base string: GET&http%3A%2F%2Fapi.myspace.com%2Fv1%2Fusers%2F341120596.XML&oauth_consumer_key%3Dhttp%253A%252F%252Fwww.myspace.com%252F387419168%26oauth_nonce%3Da6729294f12c3a1bd1daefc82d98f532%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1216105905%26oauth_token%3D%26oauth_version%3D1.0' in /hsphere/local/home/pramodkumar007/heycosmo.eparadise-india.com/prankster/PHPLib/myspace/BaseAPI.php:62 Stack trace: #0 /hsphere/local/home/pramodkumar007/heycosmo.eparadise-india.com/prankster/PHPLib/myspace/MySpaceAPI.php(172): BaseAPI->_do_get('http://api.mysp...', NULL) #1 /hsphere/local/home/pramodkumar007/heycosmo.eparadise-india.com/prankster/PHPLib/myspace/MySpaceAPI.php(33): MySpaceAPI->do_get('users/341120596', NULL) #2 /hsphere/local/home/pramodkumar007/heycosmo.eparadise-india.com/prankster/prankster_prank in /hsphere/local/home/pramodkumar007/heycosmo.eparadise-india.com/prankster/PHPLib/myspace/BaseAPI.php on line 62 "
