将Chrome驱动程序与Selenium webdriver一起使用。远程Python

时间：2017-12-01 18:56:33

标签： python python-2.7 selenium-webdriver selenium-chromedriver selenium-grid

我正在尝试使用webdriver.Remote（）在节点上启动chrome会话。 我无法启动浏览器。我可以使用webdriver.Chrome（）而不是网格。

我的节点和集线器在与客户端相同的本地计算机上运行。

这是Test.py 

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
import time

driver = webdriver.Remote(
'http://192.168.1.18:4444/wd/hub‘,
   desired_capabilities=webdriver.DesiredCapabilities.CHROME
)
time.sleep(10)
driver.quit()

以下是Test.py失败时的回溯

即使浏览器没有打开chromedriver仍然会进行LISTENING连接

chromedri 38842 admin    9u  IPv4 0xb74a80d3f95a4bab      0t0  TCP localhost:20917 (LISTEN)

我已经使用以下命令启动了节点：

java -jar selenium-server-standalone-3.8.0.jar -role node -hub http://192.168.1.18:4444/grid/register

和中心：

java -Dwebdriver.chrome.driver='/chromedriver' -jar selenium-server-standalone-3.8.0.jar -role hub

我一直试图让这个工作，我找不到我所缺少的东西。

我正在跑步： Python：2.7.13 硒：3.8

我做错了什么XD

我需要启动Chrome浏览器。

更新：

我仍然没有想到这个购买我从Grid切换到只使用Selenium Standalone并且我已经设法在AWS Ubunutu实例上工作。所以现在，这将有效。我仍然想知道为什么我无法使用Grid。

1 个答案:

答案 0 :(得分：0)

在SeleniumDriver升级后，Chrome选项不再以编程方式设置。

我刚刚回滚了我的SeleniumDriver升级，用我们的测试来测试这个功能 以前的SeleniumDriver版本：2.35.0 它按预期工作。
