Retrieve contents of URL as string

For tedious reasons to do with Hpricot, I need to write a function that is passed a URL, and returns the whole contents of the page as a single string.

I'm close. I know I need to use OpenURI, and it should look something like this:

require 'open-uri'
open(url) {
  # do something mysterious here to get page_string
}
puts page_string

Can anyone suggest what I need to add?

Solution

  • The open method passes an IO representation of the resource to your block when it yields. You can read from it using the IO#read method

    open([mode [, perm]] [, options]) [{|io| ... }] 
open(path) { |io| data = io.read }
