如何使用流式Twitter API监视Java中的主题标签？

Question

Can someone show me a java example? I was looking for it, but I haven't found nothing

This is actually quite easy, you must provide the hash tag in your track POST parameter:

The TwitterClient on github.com is a Java example of using the streaming API... it needs some work, most importantly the HttpURL needs changing to HttpsURL in TwitterClient.java:

/**
 * Extracts the host and post from the baseurl and constructs an
 * appropriate AuthScope for them for use with HttpClient.
 */
private AuthScope createAuthScope(String baseUrl) throws URIException {
    //HttpURL url = new HttpURL(baseUrl);
    HttpsURL url = new HttpsURL(baseUrl);
    return new AuthScope(url.getHost(), url.getPort());
}

and Change http://stream.twitter.com/ to https://stream.twitter.com/ in example/Example.java .

Get TwitterClient from http://github.com/gistinc/TwitterClient once you have it compiled run the example like this:

java <classpathstuff> example.Example username:password -t #YourHashTag

In CURL, make a file with this in called track.txt :

track=#YourHashTag

Then run curl like this... you can see it working:

curl https://stream.twitter.com/1/statuses/filter.json -uusername:password -d @track.txt

Hope this helps ;-)
