Save image with Mechanize and Nokogiri?

Question

I\'m using Mechanize and Nokogiri to gather some data. I need to save a picture that\'s randomly generated at each request.

In my attempt I\'m forced to download all

Answer 1

To fetch the images from the specific location:

agent = Mechanize.new
page = agent.get('http://www.domain.com')
images = page.search("#specific img")

To save the image:

agent.get(images.first.attributes["src"]).save "path/to/folder/image_name.jpg"

To get image encoded without saving:

encoded_image = Base64.encode64 agent.get(images.first.attributes["src"]).body_io.string

I ran this just to make sure that the image that was encoded can be decoded back:

File.open("images/image_name.jpg", "wb") {|f| f.write(Base64.decode64(encoded_image))}
