GAE/J에서 Twitter4J API를 사용하고 있습니다.사용자 새로 고침 페이지를 다시 사용할 때 OAuth 요청 토큰 재사용 - Twitter4j on GAE
사용자가 내 페이지를 방문했을 때 요청 토큰을 사용하고 싶습니다. (back URL이라고 함). 그리고 새로 고침 버튼을 누릅니다. 나는 그 다음 코드를 작성한다. 하지만 사용자가 새로 고침 버튼을 누르면. 인증 자격 증명 오류가 있습니다. 보류를 참조하십시오. 사용자가 처음으로 해당 토큰을 사용한 경우 제대로 작동합니다.
HomeServlet.java 코드 :
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());
내가 그렇게 할 수있는 방법을 제안 해주십시오. 나는 많은 웹 사이트에서 보았다. 사용자는 동일한 토큰으로 사용자를 보유합니다. 사용자가 브라우저 새로 고침 단추를 반복해서 눌러도.
도와주세요.
