如何使用 Watir 在没有图像的情况下启动 Chrome？

Question

I have tried this method but its not working .

 prefs = {
        :profile => {
            :managed_default_content_settings => { 
              :images => 2
            }
        }
    }

    Watir::Browser.new :chrome, :prefs => prefs
    browser.goto "http://www.example.com" 

Answer 1

I think it is like this

 profile = Selenium::WebDriver::Chrome::Profile.new
        profile['webkit.webprefs.loads_images_automatically'] = false

        @browser = Watir::Browser.new :chrome, :profile => profile

Answer 2

:prefs needs to be a key within the :options Hash:

browser = Watir::Browser.new :chrome, options: {prefs: prefs}

Specifically for disabling images:

browser = Watir::Browser.new(
  :chrome,
  options: {
    prefs: {'webkit.webprefs.loads_images_automatically' => false}
  }
)
browser.goto('www.google.com')
p browser.image.loaded?
#=> false

Answer 3

First, create a browser object like this:

require 'watir'
browser = Watir::Browser.new

This will open an empty Chrome window (assuming you have it installed) that you can control now.

browser.goto("google.com")

Chrome will navigate to this URL, and the page will load as if you typed the URL yourself.

Now: You can do anything you would normally do on a website with your mouse & keyboard.

Example:

browser.link(text: "All Posts").click
