Question

在ubuntu系统上，我试图在python-selenium测试中使用'browsernmob-proxy'。在文档here之后我安装了'browsermob-proxy'并尝试了以下python代码：

from selenium import webdriver
from browsermobproxy import Server

server = Server("/home/adietz/Projects/Venv/nosetests/lib/python2.7/site-packages/browsermobproxy/server.py")
server.start()

但是这立即失败并出现以下错误：

======================================================================
ERROR: test_example2.TestSuite.test_network
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/adietz/Projects/Venv/nosetests/local/lib/python2.7/site-packages/nose/case.py", line 197, in runTest
    self.test(*self.arg)
  File "/home/adietz/Projects/Jenkins/bsp-usecase-tests/selenium/test_example2.py", line 41, in test_network
    server.start()
  File "/home/adietz/Projects/Venv/nosetests/local/lib/python2.7/site-packages/browsermobproxy/server.py", line 113, in start
    stderr=subprocess.STDOUT)
  File "/usr/lib/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1343, in _execute_child
    raise child_exception
OSError: [Errno 13] Permission denied

知道如何解决这个问题吗？

我也尝试使用

server = Server("/home/adietz/Projects/Venv/nosetests/lib/python2.7/site-packages/browsermobproxy")

相反，但由于以下错误而失败：

======================================================================
ERROR: test_example2.TestSuite.test_network

我可能设法让browsermob-proxy到端口8088或8089（不完全确定），但示例代码仍然无法运行....

我猜，你为代理服务器提供了错误的路径。您的代码指向browsermob代理python绑定而不是服务器。请按照以下步骤操作。

从https://github.com/lightbody/browsermob-proxy/releases位置下载browsermob代理，并将该文件解压缩到特定目录。我已解压缩/解压缩到目录C:\\Projects\\BrowserMobProxy
如果尚未安装，请安装browsermob代理绑定。 pip install browsermob-proxy

然后您可以在编码中指向服务器路径，如下所示。我正在使用Windows。如下所示。

from browsermobproxy import Server
server = Server("C:\\Projects\\BrowserMobProxy\\bin\\browsermob-proxy")
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.uk")
proxy.har # returns a HAR JSON blob

server.stop()
driver.quit()

请相应地更改代理路径（您已下载或解压缩的位置）。

尝试将browsermob-proxy与selenium一起使用时出现错误的替换错误
