Capybara, Selenium, headless Chrome, Ubuntu Net::ReadTimeout -


i saw similar question mine. works fine on os x, throws errors on ubuntu 14.04. retracing post, getting same error. original poster gave , used poltergeist / phantomjs instead. i'd make work chrome phantomjs no longer being maintained.

net::readtimeout: net::readtimeout , selenium::webdriver::error::unknownerror: unknown error: chrome failed start on rails 5.1.beta system test

here install steps on ubuntu:

apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 40976eaf437d05b5 wget -q -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -  cat <<eof > /etc/apt/sources.list.d/google-chrome.list deb http://dl.google.com/linux/chrome/deb/ stable main eof apt-get update apt-get install --force-yes -y google-chrome-stable cd /root/ && curl -o "http://chromedriver.storage.googleapis.com/2.32/chromedriver_linux64.zip" cd /root/ && unzip chromedriver_linux64.zip && cp chromedriver /usr/bin

taking 1 step @ time, confirmed google-chrome, chromedriver installed correctly , work fine. selenium driver works fine. 

link = env['link'] || "https://www.amazon.com" #https://stackoverflow.com/questions/44424200/how-do-i-use-selenium-webdriver-on-headless-chrome selenium::webdriver::chrome.driver_path="/usr/bin/chromedriver" if ruby_platform.include? "linux" options = %w[--headless --disable-gpu] options +=  %w[--binary='/usr/bin/google-chrome'] if ruby_platform.include? "linux" driver = selenium::webdriver.for :chrome, switches: options driver.navigate.to "#{link}" driver.save_screenshot("./screen.png") driver.quit

the capybara test times out while visiting url.

require 'capybara' include capybara::dsl  link = env['link'] || "https://www.amazon.com" options = %w[--headless --disable-gpu] options +=  %w[--binary='/usr/bin/google-chrome'] if ruby_platform.include? "linux" selenium::webdriver::chrome.driver_path="/usr/bin/chromedriver" if ruby_platform.include? "linux" capybara.register_driver(:headless_chrome) |app|     capabilities = selenium::webdriver::remote::capabilities.chrome( chromeoptions: { args: options } )     capybara::selenium::driver.new(app, browser: :chrome, desired_capabilities: capabilities ) end capybara.javascript_driver = :headless_chrome session = capybara::session.new(:headless_chrome) session.visit "#{link}"

the error following msg:

headless chrome , chromedriver support relatively new. update selenium-webdriver latest versions (3.5.2 of answer) have support it. once you've done that, if you're using latest capybara, can try using capybara provided registered driver, 

if ruby_platform.include? "linux"   selenium::webdriver::chrome.driver_path = "/usr/bin/chromedriver"   selenium::webdriver::chrome.path = "/usr/bin/google-chrome" end capybara.javascript_driver = :selenium_chrome_headless

rather needing register own driver.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...
