不使用browsermodproxy保存HAR文件

Question

我正在使用browsermobproxy，并且得到了很多我不想处理的错误

有没有一种方法可以不使用browsermobproxy获取站点的HAR文件

如果有人感兴趣，下面是我从server.log得到的错误

Running BrowserMob Proxy using LittleProxy implementation. To revert to the legacy implementation, run the proxy with the command-line option '--use-littleproxy false'.

这是我的代码：

from browsermobproxy import Server
server = Server("C:\\Users\\USER\\Desktop\\har_export\\browsermob-proxy-2.1.4\\bin\\browsermob-proxy.bat")
server.start()
proxy = server.create_proxy()

from selenium import webdriver
profile  = webdriver.FirefoxProfile()
profile.set_proxy(proxy.selenium_proxy())
driver = webdriver.Firefox(firefox_profile=profile)


proxy.new_har("google")
driver.get("http://www.google.co.in")
proxy.har # returns a HAR JSON blob

server.stop()
driver.quit()

如有任何建议/解决方案，将不胜感激

我相信您正在最新版本的JRE下运行browsermob代理。自版本16以来，refelction机制引入了一些限制，使得以前版本中使用的代码不再工作

因此，最简单的解决方案是降低JRE的等级。根据this thread，JRE 11将适合您
