Twitter4j:搜索公共推文

Question

如何使用Twitter4j库在公共推文中进行搜索？

public static void main(String[] args) {
        Twitter twitter = new TwitterFactory().getInstance();
        try {
            Query query = new Query("Cocaine");
            QueryResult result;
            do {
                result = twitter.search(query);
                List<Status> tweets = result.getTweets();
                for (Status tweet : tweets) {
                    System.out.println("@" + tweet.getUser().getScreenName() + " - " + tweet.getText());
                }
            } while ((query = result.nextQuery()) != null);
            System.exit(0);
        } catch (TwitterException te) {
            te.printStackTrace();
            System.out.println("Failed to search tweets: " + te.getMessage());
            System.exit(-1);
        }
    }

这给了我一个Authentication credentials are missing.错误

您需要为Twitter注册您的应用程序.如果您拥有自己的私人帐户,则只能这样做.获得ConsumerKey之后ConsumerSecret,AccessToken和AccessTokenSecret(他们将在您注册申请时向您展示),最简单的解决方案是将代码更改为以下示例:

public static void main(String[] args) {
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
          .setOAuthConsumerKey("yourConsumeKey")
          .setOAuthConsumerSecret("yourConsumerSecret")
          .setOAuthAccessToken("yourAccessToken")
          .setOAuthAccessTokenSecret("yourTokenSecret");
    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();
        try {
            Query query = new Query("query");
            QueryResult result;
            result = twitter.search(query);
            List<Status> tweets = result.getTweets();
            for (Status tweet : tweets) {
                System.out.println("@" + tweet.getUser().getScreenName() + " - " + tweet.getText());
            }

            System.exit(0);
        } catch (TwitterException te) {
            te.printStackTrace();
            System.out.println("Failed to search tweets: " + te.getMessage());
            System.exit(-1);
        }
}
