Pri*_*Nom 14 python selenium python-3.x selenium-webdriver geckodriver
出于某种原因,只有在打开嵌套webdriver实例时才会出现以下错误.不知道这里发生了什么.
我使用的是Windows 10, geckodriver 0.21.0和Python 3.7.

有没有人知道可能导致连接中止的原因是什么?
正如文档所说:
软件导致连接中止。已建立的连接被主机中的软件中止,可能是由于数据传输超时或协议错误。
可能的原因:
等等。
也尝试降级geckodriver 0.21.0到geckodriver 0.20.1. 你可以在这里下载。/sf/answers/3586570361/好像有问题geckodriver 0.21.0
PS:

...表示新WebBrowsing会话(即Firefox浏览器会话)的初始化已中止。
根据您的代码尝试,错误显然是create_webdriver_instance()包含以下内容的函数:
try:
ua_string = random.choice(ua_strings)
profile = webdriver.FirefoxProfile()
profile.set_preference('general.useragent.override', ua_string)
return webdriver.Firefox(profile)

因此,您不清楚在return webdriver.Firefox(profile)或中哪个功能要面对这个问题webdriver.Firefox()。
也许仔细看一下Codepen中的日志,表明错误来自webdriver.Firefox(profile)。
该错误背后可能有多种原因:
第一步将确定是否有任何软件阻止与计算机中服务器的连接。除此之外,可能的解决方案是:
确保系统上的/ etc / hosts包含以下条目:
127.0.0.1 localhost.localdomain localhost
Run Code Online (Sandbox Code Playgroud)由于连接被主机中的软件中止,因此您需要允许localhost路由,例如http://localhost:8080/reactive-commands
根据与Geckodriver 0.21.0的Keep-Alive连接,在闲置5s后无需使用Selenium Python客户端重新连接就掉线了
AutomatedTester:此问题不是因为在进行请求时我们尚未连接。如果是这个问题,我们将收到一个抛出的httplib.HTTPConnection异常。相反,当我们进行连接并关闭并尝试解析响应时,将引发BadStatusLine。现在这可能是python stdlib错误,httplib错误或selenium错误。一个Python客户端与别的东西没有表现出与保持活动连接相同的缺陷是取代的urllib WIP。
andreastt:该geckodriver团队正在扩展服务器端超时值会更合理。正如我所说,这将有助于缓解此问题,但不能从根本上解决它。无论如何,五秒钟可能太短而无法从持久的HTTP连接中获得真正的好处,将其增加到60秒左右将具有更高的性能。
Selenium 3.14.0刚刚被释放。如果您受到此问题的影响,请相应升级。

这个问题发生在我身上,由于错误是间歇性的,我最初认为这是一些防火墙或防病毒问题,但它更简单。
单击“发送”按钮时,我有一个表单被提交了两次。该按钮被设置为 type="submit" 并且当单击该按钮时一个 javascript 代码提交了这个表单。我将按钮更改为 type="button",问题就解决了。
