HI
I am trying to get the request token from google to get the playlist
of the user .
this is the code I am using
string signature = objOAuthBase.GenerateSignature(uri,
objOAuthBase.UrlEncode(service.ConsumerKey), service.ConsumerSecret,
"", "", "GET", timestamp, nonce, out normalisedurl, out
normalisedparameters);
signature = objOAuthBase.UrlEncode(signature);
StringBuilder authHeader = new StringBuilder();
authHeader.Append("OAuth oauth_version=\"1.0\", ");
authHeader.Append("oauth_nonce=\"");
authHeader.Append(nonce);
authHeader.Append("\", ");
authHeader.Append("oauth_timestamp=\"");
authHeader.Append(timestamp);
authHeader.Append("\", ");
authHeader.Append("oauth_consumer_key=\"");
authHeader.Append(service.ConsumerKey);
authHeader.Append("\", ");
//authHeader.Append("oauth_callback=\"");
//authHeader.Append(callback);
//authHeader.Append("\", ");
authHeader.Append("oauth_signature_method=\"");
authHeader.Append(service.SignatureMethod);
authHeader.Append("\", ");
authHeader.Append("oauth_signature=\"");
authHeader.Append(signature);
authHeader.Append("\"");
string strAuthHeader = authHeader.ToString();
string requestUrl = "";
if (string.IsNullOrEmpty(scope))
{
requestUrl = service.RequestTokenUrl;
}
else
{
QueryDataCollection path = new QueryDataCollection();
path.Add(new QueryData("scope", scope));
requestUrl = path.ToString(service.RequestTokenUrl);
}
Uri uri1 = new Uri(requestUrl);
try
{
HttpWebRequest objhttp = (HttpWebRequest)
WebRequest.Create(uri1);
objhttp.ContentType = "application/x-www-form-
urlencoded";
objhttp.Accept = "*/*";
//objhttp.ContentLength = 0;
objhttp.KeepAlive = true;
objhttp.Method = "GET";
objhttp.Headers.Add("Authorization", strAuthHeader);
HttpWebResponse objresp = (HttpWebResponse)
objhttp.GetResponse();
StreamReader sr = new StreamReader
(objresp.GetResponseStream());
string response = sr.ReadToEnd();
QueryDataCollection str = new QueryDataCollection
(response);
QueryData objqueryData = str.GetQueryDataByName
("oauth_token");
if (objqueryData != null)
{
requestToken = objqueryData.value;
//requestToken = requestToken.Substring(0,
requestToken.Length - 1);
}
else
{
}
sr.Close();
}
catch (WebException e)
{
string estr = e.ToString();
StreamReader srError = new StreamReader
(e.Response.GetResponseStream());
string responseError = srError.ReadToEnd();
including the parameters in Heaader :
OAuthorization: OAuth oauth_version="1.0", oauth_nonce="8531634",
oauth_timestamp="1264766288", oauth_consumer_key="www.MyWebsite.com",
oauth_signature_method="HMAC-SHA1",
oauth_signature="Iq6zrSRXUhjI11VHcnVmq1Z03Oc%3D"
The above code works fine with the Twitter API but doesnt work with
the Google.
I am getting bad request from the service provider 400.
also Signature_invalid
base_string :
GET&https%3A%2F%2Fwww.google.com%2Faccounts%2FOAuthGetRequestToken&
oauth_consumer_key%3Dwww.MyWebsite.com%26
oauth_nonce%3D300458%26
oauth_signature_method%3DHMAC-SHA1%26
oauth_timestamp%3D1264687595%26
oauth_version%3D1.0%26
scope%3Dhttp%253A%252F%252Fgdata.youtube.com
