如果网站崩溃，有没有办法让机器人自动重启
[英]is there a way to get a bot to automatically restart if the site crashes
问题描述
如果站点崩溃，有没有办法让这个机器人自动重新启动，如果站点没有正确加载，是否有办法让机器人刷新页面。 因为我无法在刷新时获得 xpath 并且我不知道如果机器人没有实现其目标如何重新启动

正如评论中所要求的，这是最简单但不是理想的方式。 由于您的try except子句不包含except子句，因此它们在您的代码中没有任何作用，除了它只是抑制您的所有TimeoutException ，您实际上需要它们，因为您需要知道它遇到什么错误。 为了改进这个解决方案，您可以考虑拆分try except子句并仅重新执行那些等待元素行而不是整个脚本。
