[英]Python Selenium session deleted because of page crash from unknown error: cannot determine loading status from tab crashed
问题可能是内存使用。 该页面开始变得非常缓慢,并且在某些时候会出现以下错误消息

继承人的一些链接,我查看了类似的问题,我尝试添加选项,但它不起作用。 其他一些技巧真的让我感到困惑,所以我希望有人能在这里帮助我(我对编码很陌生)
这是我浏览的链接
selenium.WebDriverException:未知错误:会话因选项卡崩溃而被删除
python linux selenium:无法访问chrome
未知错误:会话因未知错误导致页面崩溃而被删除:无法确定 ChromeDriver Selenium 崩溃的选项卡的加载状态
只是为了澄清程序的目标是获取所有配置文件的列表并从中抓取内容,这就是为什么程序的这一部分首先加载整个页面以获取所有这些链接(afaik,我不能只用 bsoup 获取它们,因为javascript)所以我没有任何解决方法谢谢!
就像我在评论中提到的那样。 这对初学者来说不是一件容易的事。 这段代码应该给你一个开始。
这里最大的问题是,结果是通过 iframe 加载的,所以你需要先得到这个。
看一下这段代码,它会获取配置文件的基本信息,并将它们作为 json 返回。 如果您需要对此进行更多解释,请随时在评论中提问。

解决方案是从 dom 树中删除元素,就像上面@pcalkins 所说的那样,dom 树似乎“超载”,否则
Message: unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed

发生此错误是因为没有足够的等待时间来加载网页
