超过限速

Question

我运行了我的代码，获得了一些数字= 50000条推文的推文，但在得到其中一些后我得到了这个错误。我在错误消息中查看了以下链接，但无法获得任何帮助

[WARNING]

我找到了一些没有解决方案的类似帖子，除了一个我没有做好的帖子，由于我的声誉，我无法写评论！

twitter4j中的

有RateLimitStatus个对象。您可以在一些api调用后访问此对象。例如：

User user = twitter.showUser(userId);
user.getRateLimitStatus();
//OR
IDs followerIDs = twitter.getFollowersIDs(user.getScreenName(), -1);
followerIDs.getRateLimitStatus();
//OR
QueryResult result = twitter.search(query);
result.getRateLimitStatus();

也许您可以使用函数来处理速率限制，如下所示：

private void handleRateLimit(RateLimitStatus rateLimitStatus) {
    //throws NPE here sometimes so I guess it is because rateLimitStatus can be null and add this condition
    if (rateLimitStatus != null) {
        int remaining = rateLimitStatus.getRemaining();
        int resetTime = rateLimitStatus.getSecondsUntilReset();
        int sleep = 0;
        if (remaining == 0) {
            sleep = resetTime + 1; //adding 1 more seconds
        } else {
            sleep = (resetTime / remaining) + 1; //adding 1 more seconds
        }

        try {
            Thread.sleep(sleep * 1000 > 0 ? sleep * 1000 : 0);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

或者这个：

private void handleRateLimit(RateLimitStatus rateLimitStatus) {
    int remaining = rateLimitStatus.getRemaining();
    if (remaining == 0) {
        int resetTime = rateLimitStatus.getSecondsUntilReset() + 5;
        int sleep = (resetTime * 1000);
        try {
            Thread.sleep(sleep > 0 ? sleep : 0);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

希望这有帮助。

任何其他/更好的方法也将受到赞赏。
