[英]Twitter4j TwitterStream doesn't get all tweets
I am trying to get all the tweets on twitter through the twitter4j TwitterStream object. 我试图通过twitter4j TwitterStream对象获取Twitter上的所有推文。 I'm not sure that I am getting all the tweets. 我不确定我收到了所有的推文。 For testing the delay after which the streaming API returns the tweet, I posted a tweet from my account on twitter. 为了测试流API返回推文之后的延迟,我在twitter上发布了一条推文。 But I didn't receive that tweet even after a long time. 但即使很长一段时间后我也没有收到这条推文。
Does the twitter4j catch each and every tweet posted on twitter or it loses a good percentage of the tweets? twitter4j是否会抓住Twitter上发布的每条推文,或者它的推文丢失率很高? Or am I doing something wrong here? 或者我在这里做错了什么? Here's the code that I am using to get the tweets: 这是我用来获取推文的代码:
StatusListener listener = new StatusListener(){
int countTweets = 0; // Count to implement batch processing
public void onStatus(Status status) {
countTweets ++;
StatusDto statusDto = new StatusDto(status);
session.saveOrUpdate(statusDto);
// Save 1 round of tweets to the database
if (countTweets == BATCH_SIZE) {
countTweets = 0;
session.flush();
session.clear();
}
}
public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {}
public void onTrackLimitationNotice(int numberOfLimitedStatuses) {}
public void onException(Exception ex) {
ex.printStackTrace();
}
public void onScrubGeo(long arg0, long arg1) {
// TODO Auto-generated method stub
}
};
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(Twitter4jProperties.CONSUMER_KEY)
.setOAuthConsumerSecret(Twitter4jProperties.CONSUMER_SECRET)
.setOAuthAccessToken(Twitter4jProperties.ACCESS_TOKEN)
.setOAuthAccessTokenSecret(Twitter4jProperties.ACCESS_TOKEN_SECRET);
TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();
twitterStream.addListener(listener);
session = HibernateUtil.getSessionFactory().getCurrentSession();
transaction = session.beginTransaction();
// sample() method internally creates a thread which manipulates TwitterStream and calls these adequate listener methods continuously.
twitterStream.sample();
I'm open to contradiction on this, but I believe it works like this... 我对此持开放态度,但我认为它的作用是这样的...
Streaming API only gives a sample of tweets for non-partners. Streaming API仅提供非合作伙伴的推文样本。 It's the "garden hose" as opposed to the "firehose" which a few Twitter partners get. 它是“花园软管”,而不是一些Twitter合作伙伴得到的“firehose”。 But you can apply for full access. 但您可以申请完全访问权限。
.sample() gives this "garden hose". .sample()给出了这个“花园软管”。 Your twitter account won't have access to the firehose, although I think there is a twitterStream for the firehose if you did have access. 您的Twitter帐户将无法访问firehose,但我认为如果您确实有访问权限,则会有一个用于firehose的twitterStream。
