Hi,
I am running into some issues regarding Authentication of my signed
request. Validation of signed request always fails.
For simplicity of debugging, Here are the list of parameters that I am
using to generate base string
List<QueryParameter> parameters = new List<QueryParameter>();
parameters.Add(new QueryParameter("oauth_nonce" ,
"1255174236461304000"));
parameters.Add(new QueryParameter("oauth_timestamp",
"1255174236"));
parameters.Add(new QueryParameter("oauth_signature_method", "RSA-
SHA1"));
parameters.Add(new QueryParameter("oauth_consumer_key",
"orkut.com"));
parameters.Add(new QueryParameter("oauth_token", ""));
parameters.Add(new QueryParameter("opensocial_owner_id",
"04260157720044639260"));
parameters.Add(new QueryParameter("opensocial_viewer_id",
"04260157720044639260"));
parameters.Add(new QueryParameter("opensocial_app_id",
"07513949224686644859"));
parameters.Add(new QueryParameter("opensocial_app_url", "http://
www.knownmarket.com/KMWeb/KnownMarket.xml"));
parameters.Add(new QueryParameter("xoauth_signature_publickey",
"pub.1199819524.-1556113204990931254.cer"));
//Commented Out because including also didnt help
//parameters.Add(new QueryParameter("opensocial_container",
"http://www.orkut.com";));
//parameters.Add(new QueryParameter("oauth_body_hash",
"HC2N0z5sbRPkI4csJ00ilMlXzes="));
//parameters.Add(new QueryParameter("xoauth_public_key", "pub.
1199819524.-1556113204990931254.cer"));
//parameters.Add(new QueryParameter("oauth_version","1.0"));
parameters.Sort(new QueryParameterComparer());
string normalizedUrl = "http://www.knownmarket.com/KMWeb/
ListingSvc.asmx";
string normalizedRequestParameters = NormalizeRequestParameters
(parameters);
StringBuilder signatureBase = new StringBuilder();
signatureBase.AppendFormat("{0}&", "POST");
signatureBase.AppendFormat("{0}&", UrlEncode
(normalizedUrl));
signatureBase.AppendFormat("{0}", UrlEncode
(normalizedRequestParameters));
return signatureBase.ToString();
I tried the C# example provided on
http://wiki.opensocial.org/index.php?title=Validating_Signed_Requests
but even that didnt help.
Gurus, do let me know if I am missing out anything here?
Thanks,
-Akash
