在没有 browsermodproxy 的情况下保存 HAR 文件

Question

我正在使用 browsermobproxy，遇到了很多我不想处理的错误。

有没有办法在不使用 browsermobproxy 的情况下获取网站的 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()

任何建议/解决方案将不胜感激。

我相信您在最新版本的 JRE 下运行您的 browsermob 代理。从版本 16 开始，refelction 机制引入了一些限制，使以前可以在以前版本中工作的代码不再工作。

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