虽然我习惯了 python，但我对浏览器使用的所有协议都不是很熟悉。我不想为我的 selenium webdriver 设置代理，这是我使用的代码。

from browsermobproxy import Server, Client
server = Server('/Users/***/Downloads/browsermob-proxy-2.1.1/bin/browsermob-proxy')
server.start()
proxy = server.create_proxy()
profile  = webdriver.FirefoxProfile()
profile.set_proxy(proxy.selenium_proxy())
driver = webdriver.Firefox(firefox_profile=profile)
proxy.new_har("10.203.9.156") 
driver.get("http://10.203.9.156")
print json.dumps(proxy.har, indent =2) # returns a HAR JSON blob
server.stop()
driver.quit()

我收到一条错误消息

Unable to connect

这是来自代理的 HAR

这是我为 ip 和 google 得到的两个响应。

10.203.9.156 google.com

有人可以解释这个原因以及如何纠正这个问题吗？

BMP 很可能拒绝与主机的连接，因为https://10.203.9.156/login.html提供的证书对该 IP 地址无效。在嵌入式模式和命令行/独立/REST API 模式下，都有一个trustAllServers选项可以禁用证书检查。我不确定 Python 包装器是否公开了该选项；我建议咨询 Pyhton 包装器的文档，如果没有，请提交 PR。
