Selenium-无响应脚本错误(Firefox) [英] Selenium - Unresponsive Script Error (Firefox)

问题描述

此问题曾被问过，但给出的答案似乎对我不起作用.问题是，当使用Selenium打开页面时，我看到许多无响应脚本"弹出窗口，它们引用了各种脚本.

This question has been asked before, but the answer given does not seem to work for me. The problem is, when opening a page using Selenium, I get numerous "Unresponsive Script" pop ups, referencing varying scripts.

当我使用不带Selenium的Firefox打开页面时，没有任何错误.另外，奇怪的是，当我手动使用硒打开页面时，它可以工作.所以我什至无法找出问题所在.

When I open the page using Firefox without Selenium, I get no errors. Also, oddly, when I open the page using selenium manually it works. So I can't even pinpoint the problem.

我可以共享代码，但是没有必要.本质上会发生什么:

I can share the code, but doing so isn't necessary. Essentially what happens is this:

1. 程序从MySQLdb收集URL的元组
2. 创建URL列表
3. 根据某些因素，尝试使用urllib2或Selenium打开URL.
4. 使用硒打开时，每次都创建一个新实例，所以:

1. Program collects tuple of urls from MySQLdb
2. Creates list of URLS
3. Attempts to open URLS either using urllib2, or selenium, based on certain factors.
4. When opening using selenium, creates new instance each time, so:

driver = webdriver.Firefox()
driver.get(url)
do other things (either open links or get page source)
driver.close()

据我所知，错误发生在第二步(获取URL).

As far as I can tell, the error is occurring on the second step (get url).

我已将about:config中的脚本等待条件设置为非常高的数字，即0，仍然出现错误.

I have set the script wait condition in about:config to very high numbers, and 0, and I still get the error.

这个问题有解决方案吗?

Is there a solution to this problem?

注意，我并不是为了测试而打开自己的页面.相反，我正在打开第三方站点，以获取某些数据.还要注意，有时卷可能会变得很高(很多页面同时由不同的程序打开)-也许是问题所在?

Note, I am not opening my own pages for testing purposes. Rather, i am opening a third party site, to obtain certain data. Note also, that sometimes volume can get pretty high (a lot of pages being opening by different programs at the same time) - maybe that's the problem??

我现在的问题主要是我什至无法在另一台计算机上复制该问题，我完全迷失了.我希望外面的其他人也遇到类似的问题，并找到了解决方案.我觉得这与Firefox中的设置有关(与about:config无关).

My problem right now is mostly that I can't even replicate the problem on another computer, I am just completely lost. I hoping someone else out there has had a similar problem and found a solution. I have a feeling this has something to do with the settings in Firefox (not about:config).

推荐答案

尝试了许多设置之后，我认为我找到了一个可行的设置，可惜在这里提到了，我只是不太了解如何使用它(我从未处理过硒中的firefox配置文件设置):

After trying many settings, I think I have found one that works, and, alas, it was mentioned here, I just didn't really understand how to use it (b/c I had never dealt with firefox profile setting in selenium): Selenium & Firefox: How can i turn off "Unresponsive script" warnings?

解决方案如下:

from selenium import webdriver
fp = webdriver.FirefoxProfile()
fp.set_preference("dom.max_chrome_script_run_time", 0)
fp.set_preference("dom.max_script_run_time", 0)
driver = webdriver.Firefox(firefox_profile=fp)
