/**
 * Get the consumer token with the given parameters and URL. The determination of whether the retrieved token

 * @param details      The resource details.
 * @param tokenURL     The token URL./*  ww w  .  j a  va  2 s  . c  om*/
 * @param httpMethod   The http method.
 * @param requestToken The request token, or null if none.
 * @param additionalParameters The additional request parameter.
 * @return The token.
