Need help passing variable to Net::HTTP

ruby-talk
1

I have used Net::HTTP like this:

Net::HTTP.get 'google.com', '/index.html'

I would like to pass it a variable instead.

I tried this:

irb(main):001:0> require 'net/http'
=> true
irb(main):002:0> url = String.new
=> ""
irb(main):003:0> url = "'google.com', '/index.html'"
=> "'google.com', '/index.html'"
irb(main):004:0> Net::HTTP.get_print(url)
NoMethodError: undefined method `host' for "'google.com',
'/index.html'":String
  from /usr/lib/ruby/1.8/net/http.rb:379:in `get_response'
  from /usr/lib/ruby/1.8/net/http.rb:337:in `get_print'
  from (irb):4
  from :0

How do I pass a variable to Net:HTTP ?

url="google.com/index.html"
Net::HTTP.get_print(URI.parse(url))

get and get_print expect an URI, if you don't specify both host and path as strings.

You already got your answer, but I wanted to point out that:

irb(main):001:0> require 'net/http'
=> true
irb(main):002:0> url = String.new
=> ""

You don't need to do this, since you are assigning a new value to the
url variable just below. You are creating an object that you don't use
at all.

irb(main):003:0> url = "'google.com', '/index.html'"
=> "'google.com', '/index.html'"

Jesus.

Here's another option you could use:

url = ['google.com', '/index.html']
Net::HTTP.get_print(*url)

or more simply:

host = 'google.com'
path = '/index.html'
Net::HTTP.get_print(host, path)

Thanks :smiley: It is working now.
This one had me stuck for hours.

Thanks for the tip Jesus. I used to program in C so I have some bad
habits. I just tried my code without creating all those objects and
everything went fine.

Might I suggest reading the first few chapters of the original Pickaxe (Programming Ruby: The Pragmatic Programmer's Guide) - lets say up to Basic I/O. Although it was written for 1.6 and is woefully out-of-date as a Ruby reference, I always found it gave one of the more digestible explanations of OO and dynamic typing.
Ofcourse you can go right ahead and buy the newest version.
Cheers,
