java - 用于获取用户推文的 Twitter Stream API

Question

我正在使用 Twitter 流 API 从用户那里获取推文。我有用户 ID 列表 我如何从 TwitterStream API 获取推文列表。我分析了以下样本

public class TwitterStreamAPI {

    public static void main(String[] args) {
        ConfigurationBuilder cb = new ConfigurationBuilder();
        cb.setDebugEnabled(true);
        cb.setOAuthConsumerKey("xxxx");
        cb.setOAuthConsumerSecret("xxx");
        cb.setOAuthAccessToken("xxx");
        cb.setOAuthAccessTokenSecret("xxx");

        TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();

        UserStreamListener listener = new UserStreamListener() {

            }

            @Override
            public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {
                //System.out.println("Got a status deletion notice id:" + statusDeletionNotice.getStatusId());

但它不打印状态

流式 api 为您提供实时事件，因此如果在您收听期间没有用户发推文，您将看不到任何输出。

如果您改为尝试获取用户的历史推文，请考虑使用 Twitter#getUserTimeline(screenName)相反，例如:

final Twitter twitter = new TwitterFactory().getInstance();
final List<Status> statuses = twitter.getUserTimeline(screenName);

for (Status status : statuses) {
    System.out.println("@" + status.getUser().getScreenName() + " - " + status.getText());
}
