Hi,

Is there any way to remotely extract a page source with Ruby from a
website that uses session data?

Thank you,

Mechanize probably does what you're looking for.

You can do it with plain old net http that comes with Ruby, though it
would take a couple of lines and require more work.

If you're using windows, the easiest way would be watir:

#literally
require 'watir'
@ie=Watir::IE.start("http://whatever/website/your/getting/source/from")
puts @ie.html

Hum. Got me thinking, it's been awhile since I've used Net::HTTP, I
may have misspoken

So watir to html file
#only problem is it leaves an ie window hanging around, but it IS tiny :slight_smile:
require 'watir'
File.open("/yea.html","w"){|f|
f.write(Watir::IE.start("http://news.google.com").html)}

Net::HTTP to html file
#just as small, easy and clean!
require 'net/http'
File.open("/yea.html","w"){|f|
f.write(Net::HTTP.get("news.google.com","/index.html"))}

Now the complexity comes when you want to navigate from page to page.
With Watir you do things like
@ie=Watir::IE.start(blah)
@ie.link(:text,/tofu/).click
Easy! And there is also firewatir which is a workalike for firefox
(haven't tried it myself)

NetHTTP is a bit more involved, but quite doable, and you don't need
windows or a gui or anything. Sadly I can't find the code I wrote
using it awhile ago.
Still lookie here, it's useful.

Thank you both. Exactly what I needed.
