How to set a proxy for webdriver? Via command-line or capabilities? #12420

boogheta · 2014-08-05T14:12:23Z

I noticed that when running phantomjs with webdriver and a proxy from the command-line (phantomjs-1.9.7 --proxy=proxyhost:3128 --webdriver=33828 for instance), then my phantom sessions do not mention any use of the proxy:

[INFO - 2014-08-05T13:51:48.042Z] Session [a4f0d400-1ca7-11e4-8775-2d27219bffd9] - Session.negotiatedCapabilities - {"browserName":"phantomjs","version":"1.9.7", "driverName":"ghostdriver", "driverVersion":"1.1.0", "platform":"linux-unknown-64bit", "javascriptEnabled":true, "takesScreenshot":false, "handlesAlerts":false, "databaseEnabled":false, "locationContextEnabled":false, "applicationCacheEnabled":false, "browserConnectionEnabled":false, "cssSelectorsEnabled":true, "webStorageEnabled":false, "rotatable":false, "acceptSslCerts":false, "nativeEvents":true,
"proxy":{"proxyType":"direct"},
"phantomjs.page.settings.userAgent":"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20130330 Firefox/21.0","phantomjs.page.settings.javascriptCanOpenWindows":false,"phantomjs.page.settings.javascriptCanCloseWindows":false}

I assume this means the webdriver is already using the proxy, and then the phantom sessions through the webdriver do not need to use the proxy since it is already being used, but I just wanted to be sure and know whether I should rather:

stay as such and only set the proxy in command line?
forget about the command lien option and set the proxy in the capabilities for each session?
or even set it up in both places?

From my experience the CLI arguments are the only ones that work. Using DesiredCapabilities is not working, so the output of negotiatedCapabilities is meaningless...

Thanks, thtat's what I ended up understanding making a few tryouts by accessing a personal server from various phantom configs.

@OndraM if desired capabilities is not working then what it the work around on this?

OndraM · 2015-01-08T21:43:04Z

@kenju254 I must start the phantomjs with command line options, like --proxy=foo.bar:8080, which is really inconvenient and also confusing, as other browsers accepts proxy settings through the capabilities.

@OndraM Have you found a solution now?

kenju254 · 2015-08-03T12:27:48Z

@Accagain2014 and @OndraM i succeeded to get a solution to this . i must have forgotten to share

Accagain2014 · 2015-08-03T12:40:48Z

@kenju254 Can you share with us?

@boogheta Have you solved this problem? This troubles me a lot now. I can't find a way.

@Accagain2014: As @OndraM said, you shouldn't trust the negotiatedCapabilities outputted in the log. If you run phantom from command line with the --proxy= option it does use it although the log do not say so.
If that troubles you and you want to be sure, you can test it by accessing via phantom+proxy a local server you run and check the IP in the log for instance.

@boogheta I think it's a phantomjs problem, not the ghostdriver problem.
I use phantomjs --proxy=127.0.0.1:3128 test.js to check if check phantomjs, It returns a lot of errors.
So I don't think it's a webdriver or capabilities problem.
but I use curl -x 127.0.0.1:3128 url, It works. That proves that my proxy works.
How to solve the problem? I know phantomjs-2.0.0 has a setProxy() function, but It hasn't binary file in Linux.
I use phantomjs 1.9.7

This proves your proxy works, not that your call with Phantom does not use it. You say you have errors, can you paste them? Maybe your problems rely in your test.js code?
