Tweepy OpenSSL.SSL.WantReadError

Python 3.6。我使用 tweepy 的 Streamer 来获取推文。效果很好。但有时，如果我让它打开超过 24 小时，就会出现此错误

我的代码相当长，关于错误，它似乎来自 urllib3、OpenSSL 和 tweepy 访问 Twitter API 的方式。所以我可以用一个来处理这个try在启动流媒体之前，但我想知道是否有更好的修复方法可以理解并避免这种情况？谢谢！

这看起来更像是临时连接超时，未由Tweepy，所以你应该只编写一个包装器来捕获异常并重新启动它。我认为这种异常无法避免，因为您连接到外部站点，有时可能会超时

你应该看看这个http://docs.tweepy.org/en/v3.5.0/streaming_how_to.html#handling-errors http://docs.tweepy.org/en/v3.5.0/streaming_how_to.html#handling-errors对于错误处理部分，看看是否on_error当连接超时发生时，您的情况会被调用

class MyStreamListener(tweepy.StreamListener):

    def on_error(self, status_code):
        if status_code == 420:
            #returning False in on_data disconnects the stream
            return False

如果这没有帮助，那么使用包装器方法
