Python selenium browser driver.back()
提问by BubblewrapBeast
I have created a little screen scraper and everything seems to be working great, the information is being pulled and saved in a db. The only problem I am having is sometimes Python doesn't use the driver.back()so it then trys to get the information on the wrong page and crashes. I have tried adding a time.sleep(5)but sometimes it still isn't working. I am trying to optimise it to take as little time as possible. So making it sleep for 30 seconds doesn't seem to be a good solution.
我创建了一个小屏幕抓取器，一切似乎都运行良好，信息正在被提取并保存在数据库中。我遇到的唯一问题是有时 Python 不使用 ，driver.back()因此它会尝试获取错误页面上的信息并崩溃。我试过添加一个，time.sleep(5)但有时它仍然不起作用。我正在尝试优化它以尽可能减少时间。所以让它休眠 30 秒似乎不是一个好的解决方案。

This is the best solution. The back() and forward() methods aren't guaranteed to work.
这是最好的解决方案。back() 和 forward() 方法不能保证工作。
driver.execute_script("window.history.go(-1)")
The JavaScript passed in accesses the pages Dom to navigate to the previous url. I hope that this solves your problem.
传入的 JavaScript 访问页面 Dom 以导航到上一个 url。我希望这能解决你的问题。
