java - 为什么我在没有超出限制的情况下会收到异常？

Question

只转发了 15 条推文，我收到一条异常(exception)消息。

403:The request is understood, but it has been refused. An accompanying error
message will explain why. This code is used when requests are being denied due
to update limits (https://support.twitter.com/articles/15364-about-twitter-limits
-update-api-dm-and-following).

message - Not authorized to use this endpoint.
code - 37

 这可能是什么原因？该限制实际上是如何运作的？

转发推文的 Java 代码:

            do {
            QueryResult result = twitter.search(new Query("#naples "));
            List<Status> statusList = result.getTweets();
            while(i.hasNext()) {
                Status s = (Status) i.next();
                long id = s.getId();
                c = new Counter();
                int totalUpdates = c.getUpdateCount();

                if(totalUpdates <= 30) { // continue to retweet
                    if(!s.isRetweeted() && !s.isRetweetedByMe()) {
                        twitter.retweetStatus(id);
                        totalUpdates++;
                        c.setUpdateCount(totalUpdates);
                    }
                } else { // Daily Limit Reached
                    limitReached = true;
                }
            }
        } while(!limitReached);

你一定要看看这个Automation rules and best practices页。

Automated retweeting of other users

We discourage the automatic retweeting of other users based on a particular keyword and may suspend accounts that engage in this behavior, particularly if they are being frequently blocked and reported as spam.

顺便说一句，我想你必须提供一些像 sleep() 这样的函数来延迟每次转发。
