我正在尝试使用代理监视python-selenium测试期间发出的任何请求。我使用的python代码如下：

from selenium import webdriver
PROXY = "0.0.0.0:9999"
webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
    "httpProxy":PROXY,
    "ftpProxy":PROXY,
    "sslProxy":PROXY,
    "proxyType":"MANUAL"
}
driver = webdriver.Firefox()
driver.get("http://www.google.co.in")
driver.quit()

然后按以下方式启动代理：

python proxpy/proxpy/proxpy.py -p 9999

当我运行python测试脚本时，出现以下错误：

Exception happened during processing of request from ('127.0.0.1', 64667)
Traceback (most recent call last):
  File "/Users/adietz/anaconda/lib/python2.7/SocketServer.py", line 596, in process_request_thread
    self.finish_request(request, client_address)
  File "/Users/adietz/anaconda/lib/python2.7/SocketServer.py", line 331, in finish_request
    self.RequestHandlerClass(request, client_address, self)
  File "/Users/adietz/Projects/Invest/browsermob/proxpy/proxpy/core.py", line 56, in __init__
    SocketServer.StreamRequestHandler.__init__(self, request, client_address, server)

    self.handle()
  File "/Users/adietz/Projects/Invest/browsermob/proxpy/proxpy/core.py", line 137, in handle
    res = self.doCONNECT(host, port, req)
  File "/Users/adietz/Projects/Invest/browsermob/proxpy/proxpy/core.py", line 188, in doCONNECT
    ssl_version = ssl.PROTOCOL_SSLv23, do_handshake_on_connect = False)
  File "/Users/adietz/anaconda/lib/python2.7/ssl.py", line 933, in wrap_socket
    ciphers=ciphers)
  File "/Users/adietz/anaconda/lib/python2.7/ssl.py", line 544, in __init__
    self._context.load_cert_chain(certfile, keyfile)
IOError: [Errno 2] No such file or directory

我怎样才能解决这个问题？如何避免此错误？我如何仅监视请求和响应...？

在Linux机器上，错误是等效的：

解决方案

这看起来像代理本身的问题。我检查了Github页面，最近一次更新是四年前。如果您能够切换代理，我建议您使用Browsermob，它非常用户友好。由于您使用的是python，因此我从著名的Selenium贡献者那里找到了一个包装器库：https : //github.com/AutomatedTester/browsermob-proxy-py
