 * requests are made as "POST" with method specified in the body).

 * @param method
 *            - the HTTP method to use ("GET", "POST", etc.)
 * @param params
 *            - the query parameter for the URL (e.g. access_token=foo)
 * @return the URL contents as a String
 * @throws MalformedURLException
 *             - if the URL format is invalid
 * @throws IOException
 *             - if a network problem occurs
