I’m trying to implement upload_with_media in twitcurl c++ library. here’s the code that I implemented …
bool twitCurl::uploadPictureRaw( char *data, int size, std::string& newStatus )
{
if( newStatus.empty() || !data )
{
return false;
}
/* Prepare new status message */
std::string newStatusMsg = urlencode( newStatus );
/* part PerformPOST */
std::string postUrl = twitCurlDefaults::TWITCURL_PROTOCOLS[1] + twitterDefaults::TWITCURL_MEDIA_URL; // http://api.twitter.com/1.1/statueses/upload_with_media
std::string dataStr = twitCurlDefaults::TWITCURL_STATUSSTRING + newStatusMsg;
/* Return if cURL is not initialized */
if( !isCurlInit() )
{
return false;
}
std::string oAuthHttpHeader;
struct curl_slist* pOAuthHeaderList = NULL;
/* Prepare standard params */
prepareStandardParams();
/* Set http request, url and data */
curl_easy_setopt( m_curlHandle, CURLOPT_URL, postUrl.c_str() );
curl_easy_setopt( m_curlHandle, CURLOPT_POST, 1 );
/* Set OAuth header */
m_oAuth.getOAuthHeader( eOAuthHttpPost, postUrl, std::string(""), oAuthHttpHeader );
if( oAuthHttpHeader.length() )
{
pOAuthHeaderList = curl_slist_append( pOAuthHeaderList, oAuthHttpHeader.c_str() );
if( pOAuthHeaderList )
{
curl_easy_setopt( m_curlHandle, CURLOPT_HTTPHEADER, pOAuthHeaderList );
}
}
pOAuthHeaderList = curl_slist_append(pOAuthHeaderList, "Expect:"); // for big data transmission
curl_httppost *formpost=NULL;
curl_httppost *lastptr=NULL;
curl_formadd( &formpost, &lastptr, CURLFORM_COPYNAME, "status", CURLFORM_COPYCONTENTS, newStatusMsg.c_str(), CURLFORM_END );
curl_formadd( &formpost, &lastptr, CURLFORM_COPYNAME, "media[]", CURLFORM_COPYCONTENTS, data, CURLFORM_CONTENTSLENGTH, size, CURLFORM_END );
curl_easy_setopt( m_curlHandle, CURLOPT_HTTPPOST, formpost );
/* Send http request */
if( CURLE_OK == curl_easy_perform( m_curlHandle ) )
{
if( pOAuthHeaderList )
{
curl_slist_free_all( pOAuthHeaderList );
}
return true;
}
if( pOAuthHeaderList )
{
curl_slist_free_all( pOAuthHeaderList );
}
return false;
}
and here’s the packet

(never mind of the url, I changed it little for test purposing)
twitter server always returns 403 with null response. I dont know what’s the problem with my transmitted packet. Is there anyone knows what’s the problem? (also you can use the edited twitcurl library at https://github.com/kuna/libtwitcurl)
thanks for reading…
