筛选twitter4j流 [英] Filter twitter4j stream

问题描述

我正在尝试使用以下代码过滤我的twitter4j流:

I'm trying to filter my twitter4j stream with the following code :

    TwitterStream twitterStream = getTwitterStreamInstance();

    // Listener
    twitterStream.addListener(listener);

    // Filter
    FilterQuery filtre = new FilterQuery();
    String[] keywordsArray = { "iphone", "samsung" };
    filtre.track(keywordsArray);
    twitterStream.filter(filtre);

    // Listening
    twitterStream.sample();

但是结果例如:

27/59 - "Taking a risk over something only means that you want it more than anything"
28/63 - The more attractive you are, the more awkward I am.
29/64 - the thing about pain is that it demands to be felt

我没有恢复要关注的关键字，这是哪里出了问题?

And I don't recover the keywords I want to follow, where is the problem ?

推荐答案

您不需要:

twitterStream.sample();

如果将其删除，则应该开始看到与您的过滤器查询相匹配的推文.

If you remove it, you should start seeing Tweets matching your filter query.

调用filter时，侦听器将收到过滤的Tweets，但是，由于随后调用sample，您将有效地将侦听器正在接收的过滤流替换为样本流，这是随机选择的Tweets.

When you invoke filter your listener will receive filtered Tweets, however because you then invoke sample you are effectively replacing the filtered-stream your listener is receiving with the sample steam, which is a random selection Tweets.

因此换句话说，调用 sample 或

So in other words call either sample or filter, but not both.
