[twitter-dev] xauth return "Failed to validate oauth signature and token"

[udta]

Hi,

I am using libtwitcurl, and converting oAuth to xAuth, but I got
"Failed to validate oauth signature and token".
I compare all I can printf data to libQtweet(xauth succesful), and
couldn't found any error....


sigBase is:
POST&https%3A%2F%2Fapi.twitter.com%2Foauth
%2Faccess_token&oauth_consumer_key%3D**************%26oauth_nonce
%3D1288319703364%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp
%3D1288319703%26oauth_version%3D1.0

oAuthHttpHeader is:
Authorization: OAuth
oauth_consumer_key="*************",oauth_nonce="1288319703364",oauth_signature="SUlWtiHEc6wZJwiY9bZDgRkSyKE
%3D",oauth_signature_method="HMAC-
SHA1",oauth_timestamp="1288319703",oauth_version="1.0"


This is my code:

bool twitCurl::xAuthAccessToken()
{
    bool retVal = false;
    FILE *fp = fopen("/tmp/twitter/xauth","w");
    std::string
url(oAuthTwitterApiUrls::OAUTHLIB_TWITTER_ACCESS_TOKEN_URL);

    if( isCurlInit() )
    {
        std::string body = "x_auth_mode=client_auth&x_auth_password="
+ urlencode(m_twitterPassword) + "&x_auth_username=" +
urlencode(m_twitterUsername);

        std::string dataStr("");

        dataStr = body;

        url += (std::string("?") + body);

        std::string oAuthHeader( "" );
        struct curl_slist* pOAuthHeaderList = NULL;

            CURL* curlHandle = curl_easy_init();;

            std::string localUrl = url;
            size_t nPos = url.find_first_of( "?" );
            if( std::string::npos != nPos )
            {
                localUrl = url.substr( 0, nPos );
            }
            dataStr = urlencode( dataStr );

            std::string oAuthHttpHeader("");
            /* Set OAuth header */
            m_oAuth.getOAuthHeader( eOAuthHttpPost, localUrl, dataStr,
oAuthHttpHeader );

            if( oAuthHttpHeader.length() > 0 )
            {
                pOAuthHeaderList =
curl_slist_append( pOAuthHeaderList, oAuthHttpHeader.c_str() );
                if( pOAuthHeaderList )
                {
                    curl_easy_setopt( curlHandle, CURLOPT_HTTPHEADER,
pOAuthHeaderList );
                }
            }

            /* Set http request, url and data */
            curl_easy_setopt( curlHandle, CURLOPT_POST, 1 );
            curl_easy_setopt( curlHandle, CURLOPT_USE_SSL,
CURLUSESSL_CONTROL);
            curl_easy_setopt( curlHandle, CURLOPT_SSLVERSION,
CURL_SSLVERSION_SSLv3);
            curl_easy_setopt( curlHandle, CURLOPT_SSL_VERIFYPEER, 0L);
            curl_easy_setopt( curlHandle, CURLOPT_SSL_VERIFYHOST, 0L);
            curl_easy_setopt( curlHandle, CURLOPT_URL, url.c_str() );
            curl_easy_setopt( curlHandle, CURLOPT_WRITEFUNCTION,
write_data );
            curl_easy_setopt( curlHandle, CURLOPT_WRITEDATA, fp );

            if( dataStr.length() )
            {
                curl_easy_setopt( curlHandle, CURLOPT_COPYPOSTFIELDS,
dataStr.c_str() );
            }

            /* Send http request */
            CURLcode code = curl_easy_perform( curlHandle );
            if( code == CURLE_OK )
            {
                retVal = true;
            }
            else
            {
                retVal = false;
            }

            if( pOAuthHeaderList )
            {
                curl_slist_free_all( pOAuthHeaderList );
            }
            fclose(fp);
    }
    return retVal;
}


Thanks.
