不使用 browsermodproxy 保存 HAR 文件

Question

我正在使用 browsermobproxy 并收到很多我不想处理的错误。

有没有办法不使用 browsermobproxy 来获取网站的 HAR 文件？

如果有人感兴趣，这是我从 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()

任何suggestions/solutions将不胜感激。

我相信你是运行你在最新版JRE下的browsermob代理。自版本 16 以来，反射机制引入了一些限制，使得以前版本中使用的代码不再有效。

所以最简单的解决方案是降级您的 JRE。根据 this thread，JRE 11 适合您。
