我没有看到相关的。默认情况下，性能日志被禁用 要启用它，请使用并配置
loggingPrefsfrom selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities.CHROME
#as per latest docs
caps['goog:loggingPrefs'] = {'performance': 'ALL'}
driver = webdriver.Chrome(desired_capabilities=caps)
driver.get('https://stackoverflow.com')
for entry in driver.get_log('performance'):
print(entry)
driver.quit()

我知道这个答案非常古老，但你知道是否有办法只获取“网络”事件（即当你进入Chrome开发者工具的“网络”选项卡时会看到什么）。我可以从日志中解析我需要的内容，但我认为有一种更有效的方法，我在理解文档时遇到了一些困难。谢谢我一直在寻找这个答案。谢谢对于较新版本的Chrome，您必须使用
caps[“goog:loggingpresfs”]={“performance”：“ALL”}
