如何从Twitter API Java JSON中获取所有url照片



有人知道是否有可能从twitter api获得所有url照片吗?作为一个例子，这条推文有4张照片https://twitter.com/wtfbaile/status/652694439584993280/photo/1我想在twitter api的一个请求中获得所有4个url的照片。

目前，为了做到这一点，我必须做2个请求。这4张url图片只在第二次请求中可用。

第一个:

                .setOAuthConsumerSecret(TwitterConstantes.APIKEYSECRET)
                .setOAuthAccessToken(TwitterConstantes.TOKEN)
                .setOAuthAccessTokenSecret(TwitterConstantes.TOKENSECRET);
        TwitterFactory tf = new TwitterFactory(cb.build());

        Query query = new Query("some cool pictures from time square, brooklyn bridge and china town");
        QueryResult result = twitter.search(query);
        System.out.println(result);
        for (Status status : result.getTweets()) {
            MediaEntity[] media = status.getMediaEntities(); //get the media entities from the status
            for(MediaEntity m : media){ //search trough the entities
                System.out.println(m.getMediaURL()); //get your url!
            }
        }
}

我找到了我的问题的解决方案，我把它贴在这里给你。

        ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
            .setOAuthConsumerKey(TwitterConstantes.APIKEY)
            .setOAuthConsumerSecret(TwitterConstantes.APIKEYSECRET)
            .setOAuthAccessToken(TwitterConstantes.TOKEN)
            .setOAuthAccessTokenSecret(TwitterConstantes.TOKENSECRET);
    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();
    double res = 5;
    //Query query = new Query(this.text);
    Query query = new Query().geoCode(new GeoLocation(latitude,longitude), res, Query.KILOMETERS.toString()); 
    query.setResultType(Query.RECENT); // get the recent tweets
    query.count(100);
    QueryResult result = twitter.search(query);
    do {
        for (Status tweet : result.getTweets()) {
            //if (tweet.isRetweet()){continue;}         
            try {
                Status tweetById = twitter.showStatus(tweet.getId());
                String url= "https://twitter.com/" + tweetById.getUser().getScreenName() 
                        + "/status/" + tweetById.getId();
                List<String> hashtags =  new ArrayList<String>();
                HashtagEntity[] hashtagsEntities = tweetById.getHashtagEntities();
                for (HashtagEntity hashtag : hashtagsEntities){
                    System.out.println(hashtag.getText());
                }
                ExtendedMediaEntity[] medias = tweetById.getExtendedMediaEntities();
                for (ExtendedMediaEntity m : medias){
                    System.out.println(m.getMediaURL());    
                }
            } catch (TwitterException e) {
                System.err.print("Failed to search tweets: " + e.getMessage());
                return;
            }
        }
        query = result.nextQuery();
        if(query!=null){
            result = twitter.search(query);
        }
    }while(query!=null);

这是基于@afaraut的一个更简单的答案。

首先确保您使用的是twitter4j的最新版本，在本例中是4.0.4，以获取tweet中的所有图片，例如tweetID ="652694439584993280":

    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
        .setOAuthConsumerKey(TwitterConstantes.APIKEY)
        .setOAuthConsumerSecret(TwitterConstantes.APIKEYSECRET)
        .setOAuthAccessToken(TwitterConstantes.TOKEN)
        .setOAuthAccessTokenSecret(TwitterConstantes.TOKENSECRET);
    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();
    String tweetID ="652694439584993280";
    try {
        twitter4j.Status sts = twitter.showStatus(Long.parseLong(tweetID));
        ExtendedMediaEntity[] medias = sts.getExtendedMediaEntities(); //get the media entities from the status
        for(ExtendedMediaEntity m : medias){ //search trough your entities
            System.out.println("this is a pic","  " +m.getMediaURL());
        }
    } catch (TwitterException e) {
        e.printStackTrace();
    }
