twitter中的流API没有响应

我正在使用twitter4j Stream API 3.0.3 jar 。 我尝试获取用户流和推文我的代码如下。 它只运行过去1小时内没有显示任何输出。

 public class StreamAPI { public static void main(String[] args) { ConfigurationBuilder cb = new ConfigurationBuilder(); cb.setDebugEnabled(true); cb.setOAuthConsumerKey("xxxx"); cb.setOAuthConsumerSecret("xxxx"); cb.setOAuthAccessToken("xxx-x"); cb.setOAuthAccessTokenSecret("xxxxx"); cb.setUseSSL(true); TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance(); RawStreamListener listener = new RawStreamListener() { @Override public void onMessage(String rawJSON) { System.out.println(rawJSON); } @Override public void onException(Exception ex) { ex.printStackTrace(); } }; twitterStream.addListener(listener); twitterStream.sample(); } } 

当我尝试获取用户时，它显示401 Authentication错误

 static UserStreamListener listener = new UserStreamListener() { @Override public void onStatus(Status status) { System.out.println("onStatus @" + status.getUser().getScreenName() + " - " + status.getText()); } @Override public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) { System.out.println("Got a status deletion notice id:" + statusDeletionNotice.getStatusId()); } @Override public void onDeletionNotice(long directMessageId, long userId) { System.out.println("Got a direct message deletion notice id:" + directMessageId); } @Override public void onTrackLimitationNotice(int numberOfLimitedStatuses) { System.out.println("Got a track limitation notice:" + numberOfLimitedStatuses); } @Override public void onScrubGeo(long userId, long upToStatusId) { System.out.println("Got scrub_geo event userId:" + userId + " upToStatusId:" + upToStatusId); } @Override public void onStallWarning(StallWarning warning) { System.out.println("Got stall warning:" + warning); } @Override public void onFriendList(long[] friendIds) { System.out.print("onFriendList"); for (long friendId : friendIds) { System.out.print(" " + friendId); } System.out.println(); } @Override public void onFavorite(User source, User target, Status favoritedStatus) { System.out.println("onFavorite source:@" + source.getScreenName() + " target:@" + target.getScreenName() + " @" + favoritedStatus.getUser().getScreenName() + " - " + favoritedStatus.getText()); } @Override public void onUnfavorite(User source, User target, Status unfavoritedStatus) { System.out.println("onUnFavorite source:@" + source.getScreenName() + " target:@" + target.getScreenName() + " @" + unfavoritedStatus.getUser().getScreenName() + " - " + unfavoritedStatus.getText()); } @Override public void onFollow(User source, User followedUser) { System.out.println("onFollow source:@" + source.getScreenName() + " target:@" + followedUser.getScreenName()); } @Override public void onDirectMessage(DirectMessage directMessage) { System.out.println("onDirectMessage text:" + directMessage.getText()); } @Override public void onUserListMemberAddition(User addedMember, User listOwner, UserList list) { System.out.println("onUserListMemberAddition added member:@" + addedMember.getScreenName() + " listOwner:@" + listOwner.getScreenName() + " list:" + list.getName()); } @Override public void onUserListMemberDeletion(User deletedMember, User listOwner, UserList list) { System.out.println("onUserListMemberDeleted deleted member:@" + deletedMember.getScreenName() + " listOwner:@" + listOwner.getScreenName() + " list:" + list.getName()); } @Override public void onUserListSubscription(User subscriber, User listOwner, UserList list) { System.out.println("onUserListSubscribed subscriber:@" + subscriber.getScreenName() + " listOwner:@" + listOwner.getScreenName() + " list:" + list.getName()); } @Override public void onUserListUnsubscription(User subscriber, User listOwner, UserList list) { System.out.println("onUserListUnsubscribed subscriber:@" + subscriber.getScreenName() + " listOwner:@" + listOwner.getScreenName() + " list:" + list.getName()); } @Override public void onUserListCreation(User listOwner, UserList list) { System.out.println("onUserListCreated listOwner:@" + listOwner.getScreenName() + " list:" + list.getName()); } @Override public void onUserListUpdate(User listOwner, UserList list) { System.out.println("onUserListUpdated listOwner:@" + listOwner.getScreenName() + " list:" + list.getName()); } @Override public void onUserListDeletion(User listOwner, UserList list) { System.out.println("onUserListDestroyed listOwner:@" + listOwner.getScreenName() + " list:" + list.getName()); } @Override public void onUserProfileUpdate(User updatedUser) { System.out.println("onUserProfileUpdated user:@" + updatedUser.getScreenName()); } @Override public void onBlock(User source, User blockedUser) { System.out.println("onBlock source:@" + source.getScreenName() + " target:@" + blockedUser.getScreenName()); } @Override public void onUnblock(User source, User unblockedUser) { System.out.println("onUnblock source:@" + source.getScreenName() + " target:@" + unblockedUser.getScreenName()); } @Override public void onException(Exception ex) { ex.printStackTrace(); System.out.println("onException:" + ex.getMessage()); } }; 

是否有人可以帮助我获取有关用户，用户关注者和Twitter推文的详细信息

Answer 1

401错误代码表示您未经过正确的身份validation。 你确定那些证书是正确的吗？

测试的一个好方法是连接到常规流API（而不是用户流），看看你是否仍然获得401.如果你这样做，那么你的凭据是不正确的。 如果它有效，那么您正在请求的用户流存在问题。
