我仍在尝试使用browsermob-proxy（此处）尝试在 python selenium 测试期间监控网络流量（请参阅browsermobproxypy）。我正在使用以下脚本对其进行测试：

from browsermobproxy import Server
server = Server("/home/adietz/Projects/Invest/browsermob-proxy/browsermob-proxy-2.1.4/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.in")
proxy.har

server.stop()
driver.quit()

我设法安装了一个“browsermob.jar”文件（这里的文档中没有很好地描述它；你必须从这里下载 jar 文件）。我正在按如下方式启动代理：

java -jar ./browsermob-proxy-2.1.4/lib/browsermob-dist-2.1.4.jar --port 9090
Running BrowserMob Proxy using LittleProxy implementation. To revert to the legacy implementation, run the proxy with the command-line option '--use-littleproxy false'.

[INFO  2018-01-18T07:47:20,885 org.eclipse.jetty.util.log] (main) Started SelectChannelConnector@0.0.0.0:9090

然后我运行测试脚本

python tester1.py

但是，在日志中，我看到如下错误：

[WARN  2018-01-18T07:28:30,265 org.eclipse.jetty.util.log] (main) FAILED SelectChannelConnector@0.0.0.0:8080: java.net.BindException: Address already in use

我最好的猜测是该端口已经在使用中，或者其他东西无法正常工作。也许我需要在脚本中明确指定端口？但是怎么做呢？一个 python 文档实际上是不存在的......

  • 查看源代码（！）我想出了如何设置端口。我正在使用以下行在 python 脚本中定义服务器和端口：

    server = Server("/home/adietz/Projects/Invest/browsermob-proxy/browsermob-proxy-2.1.4/bin/browsermob-proxy", {'port':9090})

但无论我将端口设置为什么，我总是会收到以下错误：

Traceback (most recent call last):
  File "tester1.py", line 5, in <module>
    proxy = server.create_proxy()
  File "/home/adietz/Projects/Invest/browsermob-proxy/venv_browsermob/local/lib/python2.7/site-packages/browsermobproxy/server.py", line 40, in create_proxy
    client = Client(self.url[7:], params)
  File "/home/adietz/Projects/Invest/browsermob-proxy/venv_browsermob/local/lib/python2.7/site-packages/browsermobproxy/client.py", line 37, in __init__

所以一定有其他东西工作不正确......

也许我会自己编写这样的代理。似乎是更快的方法...

我们可以使用所需的端口启动 BMP 服务器，如下所示。server 接受服务器参数的字典对象。

from browsermobproxy import Server
dict={'port':8090}
server = Server(path="C:\\Projects\\BrowserMobProxy\\bin\\browsermob-proxy",options=dict)
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()

用这个初始化服务器 -

proxyserver =  Server(
       path="/root/tests/bsp_usecase_tests/bin/browsermob-proxy",
       options={'existing_proxy_port_to_use': 8090})

Browsermob-Proxy 中的内部代码正在查找'options'名为 的字典中的键'existing_proxy_port_to_use'，否则它使用默认值，即空字典。
