我在GAE/J上使用Twitter4J API。當用戶刷新頁面時重用OAuth請求令牌 - GAE上的Twitter4j
我想在用戶訪問我的頁面時使用請求令牌。 （回叫URL）。然後按刷新按鈕。我爲此編寫下面的代碼。但是當用戶按刷新按鈕。我收到驗證憑據錯誤。請參閱stacktrance。當用戶第一次使用該標記時，它工作正常。
HomeServlet.java代碼：
HttpSession session = request.getSession();
twitter.setOAuthConsumer(FFConstants.CONSUMER_KEY,
FFConstants.CONSUMER_SECRET);
String token = (String) session.getAttribute("token");
String authorizedToken = (String)session.getAttribute("authorizedToken");
User user = null;
if (!token.equals(authorizedToken)){
AccessToken accessToken = twitter.getOAuthAccessToken(
token, (String) session
.getAttribute("tokenSecret"));
twitter.setOAuthAccessToken(accessToken);
user = twitter.verifyCredentials();
session.setAttribute("authorizedToken", token);
session.setAttribute("user", user);
}else{
user = (User)session.getAttribute("user");
}
TwitterUser twitterUser = new TwitterUser();
twitterUser.setFollowersCount(user.getFollowersCount());
twitterUser.setFriendsCount(user.getFriendsCount());
twitterUser.setFullName(user.getName());
twitterUser.setScreenName(user.getScreenName());
twitterUser.setLocation(user.getLocation());
請建議我怎麼能做到這一點。我在很多網站上看到過。它們以相同的標記保留用戶。即使用戶一次又一次按瀏覽器刷新。
請幫忙。
