How to remove Scrollbar in ChromeDriver, how to change http-agent?

问题

I use IWebDriver driver = new ChromeDriver(options) in C#

When I take .GetScreenshot();, often see scrollbar, is there a way to remove it?

2nd question, how to mock/change http_agent in ChromeDriver?

回答1:

Scrollbar issue:

• Try using Chrome switches when starting webdriver. See http://peter.sh/experiments/chromium-command-line-switches/ or chrome://flags/ in Chrome.
• You can also make Chromedriver open the url in a popup without scrollbars. You can do this using some Javascript.
• Or you could create a user_data/Default/User StyleSheets/Custom.css similar to the one below and launch Chrome with {--user-data-dir=user_data}

Custom.css:

::-webkit-scrollbar {
  height: 10px;
  width: 10px;
  background-color: #999999;
  display: none;
}

html > ::-webkit-scrollbar {
  width: 0px;
  display: none;
}

::-webkit-scrollbar-thumb {
  background: #999999;
  display: none;
}

::-webkit-scrollbar-track-piece {
  background-color: #797979;
  display: none;
}
