如何使用Python立即运行Chrome浏览器版本? [英] How can I get Chrome Browser Version running now with Python?

问题描述

我正在使用硒运行应用程序，并且我想知道实际安装的chrome浏览器版本，然后再运行Chrome驱动程序以避免出于兼容性原因出现任何异常.我知道我可以使用driver = webdriver.Chrome("path\\to\\chromedriver.exe")然后使用driver.capabilities['browserVersion']来显示版本，但是如果Chrome驱动程序版本与实际的chrome浏览器版本不同，则会引发异常.

I'm running a application using selenium, and I want to know actual chrome browser version installed, before running Chrome Driver to avoid any Exception for compatibility reason. I know I can use driver = webdriver.Chrome("path\\to\\chromedriver.exe") then driver.capabilities['browserVersion'] to show version but if Chrome Driver version differ from actual chrome browser version that's raise an exception.

谢谢

已 实际上，我为自己找到了答案，找到了解决方案:

Edited: Actually I found the answer for myself, the solution I found:

from win32com.client import Dispatch

def get_version_via_com(filename):
    parser = Dispatch("Scripting.FileSystemObject")
    try:
        version = parser.GetFileVersion(filename)
    except Exception:
        return None
    return version

if __name__ == "__main__":
    paths = [r"C:\Program Files\Google\Chrome\Application\chrome.exe",
             r"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"]
    version = list(filter(None, [get_version_via_com(p) for p in paths]))[0]
    print(version)
    # result: 80.0.3987.122

推荐答案

如果您正在使用硒，则可以使用driver.capabilities获取 chrome 浏览器版本.字典.

If you are using selenium, then you can get the chrome browser version using the driver.capabilities dictionary.

driver.capabilities['browserVersion']

较早版本的chromedriver存储了chrome浏览器版本driver.capabilities['version'].如果您想要获得chrome浏览器版本而不必担心这一点，则可以使用以下代码.

Earlier version of chromedriver stored the chrome browser version driver.capabilities['version']. If you want to get chrome browser version without having to worry about this, you can use the below code.

if 'browserVersion' in driver.capabilities:
    print(driver.capabilities['browserVersion'])
else:
    print(driver.capabilities['version'])
