我正在使用硒3.14.0和最新的Chrome浏览器.

And I'm using selenium 3.14.0 and latest Chrome browser.

推荐答案

使用Python和ChromeDriver

要获取网络日志，您需要安装 BrowserMobProxy 以及硒python

To get network logs, you need to install BrowserMobProxy as well along with selenium in python

pip install browsermob-proxy

您需要启动浏览器代理并在chrome驱动程序的chrome选项中配置代理，

You need to start browser proxy and configure the proxy in chrome option of chrome driver,

from browsermobproxy import Server
from selenium import webdriver

server = Server("path/to/browsermob-proxy")
server.start()
proxy = server.create_proxy()

# Configure the browser proxy in chrome options
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--proxy-server={0}".format(proxy.proxy))
browser = webdriver.Chrome(chrome_options = chrome_options)

#tag the har(network logs) with a name
proxy.new_har("google")

然后您可以使用硒导航到页面

Then you can navigate to page using selenium

browser.get("http://www.google.co.in")

导航后，您可以从代理获取json格式的网络日志

After navigation, you can get the network logs in json format from the proxy

print(proxy.har) # returns a Network logs (HAR) as JSON 

在退出驱动程序之前，还要在最后停止代理服务器，

Also before quitting the driver, stop the proxy server as well at the end,

server.stop()
browser.quit()
