Strange NoMethodError

Holger Biebinger

8/7/2006 2:31:00 PM

Hi,
In the following test script (similar to pickaxe p. 700 ):

require 'net/http'
require 'uri'

def fetch (uri_str, limit=10)
fail 'http redirect limit exceeded' if limit.zero?
response = Net::HTTP.get_response(URI.parse(uri_str))
case response
when Net::HTTPSuccess
response
when Net::HTTPRedirection
fetch(response['location'], limit-1)
else
response.error!
end
end


fetch('heise.de');


with
ruby test.rb
I get the result:

Exception `NoMethodError' at /usr/local/lib/ruby/1.8/net/http.rb:380
- undefined method `request_uri' for #<URI::Generic:0x188f84
URL:heise.de>
/usr/local/lib/ruby/1.8/net/http.rb:380:in `get_response': undefined
method `request_uri' for #<URI::Generic:0x188f84 URL:heise.de>
(NoMethodError)
from /usr/local/lib/ruby/1.8/net/http.rb:545:in `start'
from /usr/local/lib/ruby/1.8/net/http.rb:379:in `get_response'
from test.rb:6:in `fetch'
from test.rb:18


I had a look at /usr/local/lib/ruby/1.8/uri/http.rb
The function was defined there:
#
# == Description
#
# Returns: path + '?' + query
#
def request_uri
r = path_query
if r[0] != ?/
r = '/' + r
end

r
end

It should be a function of the standard libray. I am quite new to
ruby. How can I debug this problem? Or any hints what I can do?

Thanks in advance for your help,


Holger

Oh my god ... thank you vey much. You are right. I was a it confused
because of the NoMethodError and I thought I had installed something
wrongly. Thanks for your hint :)

Wow, our resident Zionist/Nazi BDK certainly likes including loads of
impossible to follow context, by having to include/quote everything
under the sun. Apparently it's a MI5/CIA policy thing.

It's almost as though they is keeping records for some kind of
kangaroo court thing.

If BHO doesn't become a Zionist/Nazi puppet, he may not live long
enough to accomplish squat. Perhaps keeping a few live web cams on
his every move will at least make it easier to track down those
responsible.
