title: error when creating folder on dropbox via libcurl
body: <p>I am trying to make a c++ application that uses Dropbox. When I am trying to create a new folder I take the following error: {"error": "Not Found"} and "HTTP/1.1 404 Not Found".</p>
  
  <p>I have followed the instruction of Dropbox's REST Api, so I have used the POST method. (I am not sure if I can use PUT, instead).</p>
  
  <p>Here is my code:</p>
  
  <pre><code>void createDirectory(const char *new_Directory_Path)
  </code></pre>
  
  <p>{
      string create_Directory_Url = "<a href="https://api.dropbox.com/1/fileops/create_folder/sandbox/test_folder" rel="nofollow">https://api.dropbox.com/1/fileops/create_folder/sandbox/test_folder</a>";</p>
  
  <pre><code>    CURL* curl = curl_easy_init();
      if(!curl)
      {
          CURLcode res;
  
          struct curl_slist *headers = NULL;
          string my_header = "Authorization: OAuth oauth_version=\"1.0\", oauth_signature_method=\"PLAINTEXT\", 
          oauth_consumer_key=\""
                      + m_consumer_key + "\", oauth_token=\"" + m_accessKey + "\", oauth_signature=\""
                      + m_consumer_secret + "&amp;" + m_accessSecret + "\"";
          headers = curl_slist_append(headers, my_header.c_str());
  
          curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
          curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
          curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);
          curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
          curl_easy_setopt(curl, CURLOPT_POST, 1L);
          curl_easy_setopt(curl, CURLOPT_NOPROGRESS, 0);
          curl_easy_setopt(curl, CURLOPT_URL, create_Directory_Url.c_str());
  
          res = curl_easy_perform(curl);
  
          curl_slist_free_all(headers);
          curl_easy_cleanup(curl);
      }
  </code></pre>
  
  <p>}</p>
  
  <p>Please, does anyone have an idea about what am I doing wrong?</p>
