Google OpenSocial API issue about Curl Method

I am trying to build an application using Google Opensocial API. But when i make a POST request with following CURL headers, i am getting 405 Method not allowed开发者_开发百科 error :

CURLOPT_URL : http://www.orkut.com/social/rpc/
CURLOPT_POSTFIELDS : [{"method":"people.get","id":"self","params":{"userId":["@me"],"groupId":"@self","fields":["displayName","currentLocation","thumbnailUrl","gender","name"]}},{"method":"people.get","id":"friends","params":{"userId":["@me"],"groupId":"@friends","fields":["displayName","currentLocation","thumbnailUrl","gender","name"],"count":300}}]
CURLOPT_CUSTOMREQUEST : POST
CURLOPT_RETURNTRANSFER : true
CURLOPT_USERAGENT : osapi 1.0
CURLOPT_FOLLOWLOCATION : 1
CURLOPT_SSL_VERIFYPEER : false
CURLOPT_HEADER : true
CURLINFO_HEADER_OUT : true
CURLOPT_HTTPHEADER : Array
        (
            [0] => Authorization: OAuth oauth_body_hash="A3ZOHT4b3YMOzEfg+2j3v+N302E=", oauth_nonce="6ad533sdfsb9261ssdfsdf29af7d", oauth_version="1.0", oauth_timestamp="1318236734", oauth_consumer_key="www.mydomain.com", oauth_token="1%2FKhAasdfsd8YX2bfsdfsdf6MsdfsfsdfsdfJYyULWUog", oauth_signature_method="HMAC-SHA1", oauth_signature="osdf4pShOsdfsdf88nnpwsdfsdf9g%3D"

            [2] => Content-Length: 0
            [3] => User-Agent: osapi 1.0
        )

Following is the CURL-POST response I am recieving :

["http_code"] =>  int(405)
["data"] => string(12614) 
    "HTTP/1.1 405 Method Not Allowed
    Content-Type: text/html; charset=UTF-8
    Content-Length: 12462
    Date: Tue, 14 Jun 2011 08:07:58 GMT
    Server: GFE/2.0

I asked about this issue on Google Codes forum and they told me to remove following line from CURL request as my website is hosted on hostgator.

CURLOPT_CUSTOMREQUEST : POST

I tried above thing but still i am getting 405 Method not allowed error. Kindly assist me further on this issue. Do i need to modify my PHP-CURL code above to send POST request? If so, then please help me..

The Google Social specification has an example in which people.get is requested with GET, not via POST. Generally keep in mind that GET is for requesting information, while POST is for changing existing information.
