使用Twitter4j获取特定推文的收藏计数

Question

I am new to the twitter4j api, is there any way of getting no of favorite count for a particular tweet using twitter4j. I am using api version 3.0.3 for Twitter4j.

In documentation the method getFavoriteCount() is present but the same method gives compilation error in code. Should I use different version of jar file?

 public static void main(String[] args) {

     ConfigurationBuilder cb= new ConfigurationBuilder();
        cb.setDebugEnabled(true);
        cb.setOAuthConsumerKey("**************************");
        cb.setOAuthConsumerSecret("**************************");
        cb.setOAuthAccessToken("*******************************");
        cb.setOAuthAccessTokenSecret("*****************************");
        Twitter  twitter = new TwitterFactory(cb.build()).getInstance();
         User user = null;
        try {
            user = twitter.verifyCredentials();
        } catch (TwitterException e1) {
            e1.printStackTrace();
        }

        String[] test = new String[]{"teststr"};
        ResponseList<User> users;
        try {
            users = twitter.lookupUsers(test);

        for (User user1 : users) {
              if (user1.getStatus() != null)
              {
                  Paging paging = new Paging(1, 40);
                  ResponseList<Status> statusess =   twitter.getUserTimeline(user1.getName(),paging);

              for (Status status3 : statusess)
               {
                long retweetCount = status3.getRetweetCount();
                long favoriteCount = status3.getFavoriteCount();/** this line gives compilation error saying the method getFavoriteCount() is undefined for the type Status**/

               }
              }
        }
        } catch (TwitterException e) {
            e.printStackTrace();
        }

 }

Answer 1

Unfortunately, it seems like the JavaDocs on the Twitter4J site linked next to the 3.0.3 release are not correct. The actual docs are here - you can see that getFavoriteCount() isn't present in these.

It looks like Status#getFavoriteCount() was only introduced in 3.0.4 . So yes, you need to upgrade from 3.0.3 in order to use this method.

Although be aware that version 3.0.4 looks like it is under active development presently.

Answer 2

Although you have already found and marked an answer, let me provide an alternate to switching the Twitter4J version.

When using a method similar to what you are using, I had searched a lot and finally found the solution in an entirely unrelated post. Here is how you can get the Favorite count of tweets:

NOTE: This is what I use in an Android app of mine.

First, in your ConfigurationBuilder cb instance, add this one line:

cb.setJSONStoreEnabled(true);

This will return all results in a JSON format. Strangely, getting a JSON result it provides you that value.

Now, to fetch the Tweets :

try {
    Paging paging = new Paging(initPagingOffset, 200);
    statuses = twitter.getHomeTimeline(paging);

    String strTweets = DataObjectFactory.getRawJSON(statuses);
    JSONArray JATweets = new JSONArray(strTweets);

    for (int i = 0; i < JATweets.length(); i++) {
        JSONObject JOTweets = JATweets.getJSONObject(i);

        ..... // PARSE ANY OTHER DATA YOU MIGHT NEED FOR DISPLAYING THE TWEETS

        String FAV_COUNT = JOTweet.getString("favorite_count");

    }
} catch (TwitterException e) {
    e.printStackTrace();
} catch (JSONException e) {
    e.printStackTrace();
}
