Obvious. I was not supposed to set the "-port" flag.

Hi,

I'm getting the same error on server.start()

Exception: Can't connect to Browsermob-Proxy

I also have the following:

from browsermobproxy import Server
server = Server("/Users/username/Desktop/browsermob-proxy/bin/browsermob-proxy")
server.start()
proxy = server.create_proxy()

Further on terminal, if I do /Users/username/Desktop/browsermob-proxy/bin/browsermob-proxy -port 9090 I get the following error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: net/lightbody/bmp/proxy/Main : Unsupported major.minor version 51.0

It seems to be some issue with the version number, but not sure what exactly it is. Thanks.

from browsermobproxy import Server 
server = Server("browsermob-proxy-2.1.0-beta-3/bin/browsermob-proxy")
server.start()
proxy = server.create_proxy()

I run the four lines of codes and get the following error in the last line.

>>> proxy = server.create_proxy()
...
File "C:\Python27\lib\site-packages\requests\adapters.py", line 415, in send
raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', error(10054, 'An existing connection was forcibly closed by the remote host'))

I could run the four lines successfully for the first time, but after a reboot I always get this error message. The same happen in my second machine. Did I forget to release the resource or something in my first run?

I am getting the same error when trying to run the following .py script:

`import os
from browsermobproxy import Server

server = Server("/Users/javaria/Desktop/browsermob-proxy-2.0-beta-6/bin/browsermob-proxy", options={'port': 9090})
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()`

I am getting this error in console File "test1.py", line 6, in <module> server.start() File "/Users/javaria/Documents/projects/proxy-testing/browsermob-proxy-py/browsermobproxy/server.py", line 122, in start raise Exception(message) Exception: The Browsermob-Proxy server process failed to start. Check <open file '/server.log', mode 'w' at 0x10d55e4b0>for a helpful error message.

I have set my $JAVA_HOME in ~/.bash_profile, the proxy works just fine manually but it just won't run from the python script. It's not an issue with file permission as well since I'm running the script with sudo. I am new to automation and would really appreciate your help here.

chiedo avatar chiedo commented on July 18, 2024

Hahaha, thanks man. It was definitely a noob move on my part... but maybe change the readme to something like the following? Obviously you can ignore my suggestion though!

browsermob-proxy-py
===================

Python client for the BrowserMob Proxy 2.0 REST API.



How to use with selenium-webdriver
----------------------------------

Manually:

``` python 
from browsermobproxy import Server
server = Server("path/to/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()

for Chrome use

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--proxy-server={0}".format(proxy.proxy))
browser = webdriver.Chrome(chrome_options = chrome_options)

Before Running Tests

Start the browsermob-proxy with the following in your terminal and wait for the proxy to start:

path/to/browsermob-proxy

Running Tests

To run the tests in a CI environment, disable the ones that require human
judgement by using

$ py.test -m "not human" test

If you are going to watch the test, the 'human' ones should display an english
muffin instead of the american flag on the 'pick your version' page. Or at
least it does from Canada.

HI I am receiving the very same error while trying to start the server.

import sys
from browsermobproxy import Server
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
server = Server('C:/browsermob-proxy/bin/browsermob-proxy')
server.start()

Kindly please let me know what I am doing wrong

from browsermob-proxy-py.

oh it was a problem of administrative rights on py file

from browsermob-proxy-py.

aerickson avatar aerickson commented on July 18, 2024

@chiedojohn, I feel like you got misled a little. You can definitely run browsermob on a different port and still use this library... you just need to pass in an optional secondary argument - the options dict with something like:

server = Server("path/to/browsermob-proxy", options={'port': 9999}.)

Thanks @aerickson, I actually came to that same conclusion a few weeks ago!

I have the same issue as on:

  • Windows 8.1
  • Python 3.6.0 :: Anaconda 4.3.0 (64-bit)
  • selenium (3.4.3)
  • browsermob-proxy-py (0.8.0)
  • browsermob-proxy (2.1.1)

Here's the sample code:

from browsermobproxy import Server
server = Server("C:\\tools\\browsermob-proxy-2.1.1\\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()

and here's the output

I'm also hitting this issue with version 2.1.4.

When I do this on the interpreter, I get the below output.
Notice that I only hit the error the first time...

It appears that even if you start browsermob-proxy (2.1.1 and 2.1.4) on a different port (e.g. 7070), it will still spew out a proxy starting at 8081:
