尝试使用带有硒的浏览器代理时出现错误的替换错误

Question

在 ubuntu 系统上，我正在尝试使用带有 python-selenium 测试的"browsernmob-proxy"。按照这里的文档，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，但这失败并出现以下错误：

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

ProxyServerError: Browsermob-Proxy binary couldn't be found in path provided: /home/adietz/Projects/Venv/nosetests/lib/python2.7/site-packages/browsermobproxy

补遗

• 我可能设法在端口 8088 或 8089(不完全确定(上让browsermob-proxy调谐，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。你的代码指向浏览器生物代理python绑定而不是服务器。请按照以下步骤操作。

1. 从位置 https://github.com/lightbody/browsermob-proxy/releases 下载浏览器代理，并将文件解压缩到特定目录。我已经解压缩/解压缩到目录C:\Projects\BrowserMobProxy

安装

2. 浏览器代理绑定(如果尚未安装(。点安装浏览器移动代理

3. 然后，您可以在编码中指出服务器路径，如下所示。我正在使用窗户。如下所述。

   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(下载或提取的位置(。
