使用 watir-webdriver 保存图像 [英] Save image with watir-webdriver

问题描述

如何保存通过 watir-webdriver 加载的图像?所有手册和示例仅显示获取图像的 src，并使用 open-uri 保存它.但是我需要保存该图像，该图像是在我的页面加载时生成的.我怎样才能做到这一点?

How could i save image, which is loaded via watir-webdriver? All manuals and examples show only fetching src of image, and using open-uri saving it. But i need to save that image, which was generated when my page was loaded. How can i do this?

我可以同时使用 watir 和 watir-webdriver 吗?例如:

Could i use watir, and watir-webdriver at the same time? For example:

require 'watir-webdriver'
require 'watir'
@driver = Watir::Browser.new :firefox
@driver.goto (@base_url)
@img = @driver.image(id: 'CaptchaImage').save("2131.png")

我怎么能做这样的事情?或者如何从缓存中获取它?

How can i do something like this? Or else how to get it from cache?

有人可以帮我吗?
