java - 使用 twitter4j 形成流，搜索具有特定主题标签的新 Twitter

Question

我需要使用 twitter4j 针对具有特定主题标签(假设为 #test)的所有新推文更新我的 Java 应用程序。由于避免在 Twitter REST API 上进行连续轮询，我将使用 Twitter Stream API。

运行此代码我期望:

1. 运行代码
2. 打开浏览器，转到 Twitter 并发布包含 #test 的推文
3. 仅在我的应用上查看具有特定哈希码的推文的打印内容

但是..我在我的应用程序中没有看到任何内容..(查看编辑)

有人可以给我一些建议吗？

ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
  .setOAuthConsumerKey(CONSUMER_KEY)
  .setOAuthConsumerSecret(CONSUMER_SECRET)
  .setOAuthAccessToken(ACCESS_TOKEN)
  .setOAuthAccessTokenSecret(ACCESS_TOKEN_SECRET);

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

StatusListener listener = new StatusListener() {
    @Override
    public void onStatus(Status status) {
        System.out.println("@" + status.getUser().getScreenName() + " - " + status.getUser().getId() + " - " + status.getText());
    }
    @Override
    public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {
        System.out.println("Post Deletado:" + statusDeletionNotice.getStatusId());
    }
    @Override
    public void onTrackLimitationNotice(int numberOfLimitedStatuses) {
        System.err.println("Limitação:" + 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 onException(Exception ex) {
        ex.printStackTrace();
    }
};

List<String> queries = new ArrayList<String>();
queries.add("#test");

twitterStream.addListener(listener);
twitterStream.firehose(20);

String[] trackQueries = (String[]) queries.toArray(new String[queries.size()]);

FilterQuery filterQuery = new FilterQuery();
twitterStream.filter(filterQuery.track(trackQueries));

编辑:

修复一些错误后，我正在 sys.out 中读取一些内容，但是......在一些错误之后，它似乎是随机的:

然后是一些像这样的随机推文:

Answer 1

仅通过经销商向选定的公司授予对 Twitter Firehose 的访问权限。因此，除非您是这些公司之一，否则您应该使用 sample() 而不是 firehose。不过您应该会看到一些日志。您确定您的记录器设置正确吗？

编辑:阅读 this section文档并添加有效的 twitter4j.properties 文件。请注意，您必须注册 Twitter 才能获取访问 token 。一旦您拥有 token 并填充了配置文件，您就可以将其包含在类路径中。
