python - 长时间运行时出现 Tweepy 错误

问题描述

我写了一个 Twitter 机器人，它时不时地发布一张来自 reddit 的图片。我在树莓派 4 上托管这个脚本，我希望它 24/7 运行。但是，过了一会儿我得到下一个错误：

tweepy.error.TweepError：发送请求失败：HTTPSConnectionPool(host='api.twitter.com', port=443)：最大重试次数超过 url：/1.1/statuses/update_with_medi.json?status=https%3A%2F %2Fredd.it%2kftmohf（由 NewConnectionError 引起（'<urllib3.connection.VerifiedHTTPSConnection object at 0xb4771550>: 无法建立新连接：[Errno -3] 名称解析临时失败'））

我认为正在发生的事情是无论出于何种原因它都无法访问 Twitter。我正在寻找的是如何解决此问题，或者如果无法避免，我如何稍后重试以再次运行该程序。

提前致谢。
