Environment:
Chrome Driver 92.0.4515
I found that selenium.select_frame takes nearly 3 minutes to switch between main window to the frame
The issue only occurs with headless chrome, the normal chrome's still working fine.
Any solutions will be highly appreciated! Thank you!
My webdriver's arguments:
options.add_argument(f"--window-size={width},{height}")
options.add_argument("--headless")
options.add_argument("--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 "
"(KHTML, like Gecko) Chrome/84.0.4147.125 Safari/537.36 Edg/84.0.522.59")
options.add_argument("--no-sandbox")
options.add_argument("--allow-running-insecure-content")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--disable-extensions")
options.add_argument("--start-maximized")

whatsweb headless using chromedriver only works correctly when used user agent:
chrome_options.add_argument("user-agent=User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36")
then it works, but its asking the qr code even when I already used
options.add_argument(r"user-data-dir
when I go without headless then chromedriver recognize the user data dir, but in the headless its not working, what's the solution ?
Can anybody please help with the grok pattern for below example of logs?

I know it should start with below, however I can't get anyhow the User name to proceed with [%{HTTPDATE:timestamp}] and possible next would be "(?:%{WORD:verb} %{NOTSPACE:request} and not sure how to get the Device info.
Any help would be appreciated!
%{IPORHOST:clientip} %{WORD:VirtualHost} ???
Since you have customized your log format, you have to build your own grok to match the log. You can use https://grokdebug.herokuapp.com/ to debug the pattern you're going to use and you can copy some patterns from https://github.com/logstash-plugins/logstash-patterns-core/tree/master/patterns
Solved:
%{IPORHOST:clientip} %{IPORHOST:destination.domain} "CN=%{DATA:username}" [%{HTTPDATE:apache.access.time}] "(?:%{WORD:http.request.method} %{DATA:url.original} HTTP/%{NUMBER:http.version}|-)?" %{NUMBER:http.response.status_code:long} (?:%{NUMBER:http.response.body.bytes:long}|-) ("%{DATA:http.request.referrer}") ("%{DATA:user_agent.original}")
I am trying to scrape one web page from amazon with the help of Scrapy 2.4.1 over shell. Without any prior scraping amazon instantly askes for captcha entries.
I am setting another user agent as only prevention but have never before scraped the page:
scrapy shell -s USER_AGENT="Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.93 Safari/537.36"
Get one page:
>>> fetch('https://www.amazon.de/Eastpak-Provider-Rucksack-Noir-Black/dp/B0815FZ3C6/')
>>> view(response)
Results in a captcha question.
I also tried it with headers:
headers = {"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0", "Accept-Encoding":"gzip, deflate", "Accept":"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", "DNT":"1","Connection":"close", "Upgrade-Insecure-Requests":"1"}
>>> req = Request("https://www.amazon.de/Eastpak-Provider-Rucksack-Noir-Black/dp/B0815FZ3C6/", headers=headers)
>>> fetch(req)
This also results in a captcha question, while the main page can be scraped in this case.
How does amazon detect that this is a bot and how to prevent that?
I'm designing some end to end testing for my job, and I've got it up and running using nightwatch.js through chromedriver. However, we're looking to have this run on our servers, and so I wanted to be able to run it using phantomjs. Although the test performs without incident using chromedriver, Phantomjs yields the following error "phantomjs unable to locate item using css selector"
Any ideas? I've scoured the internet for a solution, to no avail.
First, check decates' comment here: https://github.com/nightwatchjs/nightwatch/issues/243#issuecomment-94287511
See how depending on the user-agent info passed from your browser to the site, the site returns different XHTML data? So if you want to use phantomjs, but are okay with it spoofing as a different browser via the user agent, you can configure phantomjs' user-agent capabilities, like this (spoofing Mac Chrome):
"desiredCapabilities": {
"browserName": "phantomjs",
"phantomjs.cli.args" : ["--ignore-ssl-errors=true"],
"phantomjs.page.settings.userAgent" : "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36"
}
Then your tests should act the same as your other browser. Using any browser you like, you can check the user-agent string that it sends here: http://www.httpuseragent.org/. Here are some other examples:
// Mac Chrome 46
"phantomjs.page.settings.userAgent" : "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36"
// Windows Chrome 46
"phantomjs.page.settings.userAgent" : "Mozilla/5.0 (Windows NT 6.3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36"
// Mac Firefox 42.0
"phantomjs.page.settings.userAgent" : "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:42.0) Gecko/20100101 Firefox/42.0"
// Windows Firefox 42.0
"phantomjs.page.settings.userAgent" : "Mozilla/5.0 (Windows NT 6.3; rv:42.0) Gecko/20100101 Firefox/42.0"
// PhantomJS 2.0
"phantomjs.page.settings.userAgent" : "Mozilla/5.0 (Macintosh; Intel Mac OS X) AppleWebKit/538.1 (KHTML, like Gecko) PhantomJS/2.0.0 Safari/538.1"
I sometimes have this effect in the difference browsers, not only phantoms. The reason seemed to be that elements are not loaded at the time of evaluating for one browser (and are loaded for another). You can debug it with checking screenshots at the point of failure.
The solution for me was using waitForElementPresent/Visible.
I have a Javascript object that i am trying to post to the server with XMLHttpRequest() using JSON.stringify(). my code works fine in all major browsers except for Safari (5.1.2). My analysis shows that Safari, is in fact sending the data. i can see the message in the Safari Developer Tools and i see the bytes received in the IIS logs and it seems accurate (48kb) but the WCF function doesn't get the object data. In looking into the wcf logs i see that the content-length is 0 for safari and has a value for chrome. Does anyone have any insight to this issue?
