Yes, I know there're already plenty of questions with this same topic, but I cannot really find out the one suite for me. I use C++ and libcurl to make a HTTP POST request, and here are some ingredients that I used for POST requests.
Signature base string POST&https%3A%2F%2Fapi.twitter.com%2Foauth %2Faccess_token&oauth_consumer_key%3DMYCONSUMERKEY%26oauth_nonce %3DXZZJd88qUu25L8wpylQ6%26oauth_signature_method%3DHMAC- SHA1%26oauth_timestamp%3D1285924211%26oauth_version%3D1.0%26x_auth_mode %3Dclient_auth%26x_auth_password%3DMYPASSWORD%26x_auth_username %3Dxoancer%40seed9.com POST Body x_auth_username=xoancer %40seed9.com&x_auth_password=MYPASSWORD&x_auth_mode=client_auth HTTP Header Authorization: OAuth oauth_nonce="XZZJd88qUu25L8wpylQ6", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1285924211", oauth_consumer_key="MYCONSUMERKEY", oauth_signature="l4L1%2Fn7w3P7U0lcxvkTizusF2TY%3D", oauth_version="1.0" I believe signature generating is not the problem since my program makes the proper one when it runs with the example at http://dev.twitter.com/pages/xauth. But without the signature parameter, I cannot found out what's wrong since every other parameters are just a given constants(except nonce, but he doesn't really matter I think.). Maybe I missed something in using libcurl, since it's first time for me to use this library, especially in setting HTTP Header. Follows are my source codes for libcurl parts. curl_global_init(CURL_GLOBAL_ALL); CURL *curl; curl = curl_easy_init(); curl_easy_reset(curl); curl_easy_setopt(curl, CURLOPT_URL, baseUrl.c_str()); // baseUrl == https://api.twitter.com/oauth/access_token curl_easy_setopt(curl, CURLOPT_POST, true); string postbody; for(int i=7;i>=5;i--) postbody += "&" + params[i].first + "=" + urlenc(params[i].second); postbody = postbody.substr(1); // postbody == x_auth_username=xoancer %40seed9.com&x_auth_password=MYPASSWORD&x_auth_mode=client_auth curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postbody.c_str()); string header = "Authorization: OAuth " + params[1].first + "=\"" + params[1].second + "\", " + params[2].first + "=\"" + params[2].second + "\", " + params[3].first + "=\"" + params[3].second + "\", " + params[0].first + "=\"" + params[0].second + "\", oauth_signature=\""; header += urlenc(base64encoded); header += "\", oauth_version=\"1.0\""; // header == Authorization: OAuth oauth_nonce="XZZJd88qUu25L8wpylQ6", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1285924211", oauth_consumer_key="MYCONSUMERKEY", oauth_signature="l4L1%2Fn7w3P7U0lcxvkTizusF2TY%3D", oauth_version="1.0" curl_slist* responseHeaders = NULL ; responseHeaders = curl_slist_append( responseHeaders , header.c_str() ) ; curl_easy_setopt( curl , CURLOPT_HTTPHEADER , responseHeaders ) ; string res; curl_easy_setopt( curl, CURLOPT_WRITEFUNCTION, write_callback ); curl_easy_setopt( curl, CURLOPT_WRITEDATA, &res ); curl_easy_setopt(curl, CURLOPT_HEADER, true); curl_easy_setopt( curl, CURLOPT_SSL_VERIFYPEER, false); CURLcode rc = curl_easy_perform(curl); If you find some mistakes, please tell me.
