NET::HTTP uninitialized constant

abon · January 31, 2007, 3:58am

I’m testing NET::HTTP
after I got require’net\http’=>true.

But it resulted in…

NET::HTTP
NameError: uninitialized constant NET::HTTP
from
C:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib
/active_support/dependencies.rb:100:in `const_missing’
from (irb):9
from :0

Anyone knows what may go wrong in my setting.
THANKS

I’m testing NET::HTTP in irb.
So what I posted is the code.

Hi, it seems that you have incorrectly spelled the module name. It
should be ‘Net’ instead of ‘NET’. In any case, here’s an example from
"Programming Ruby’ which
you should have a copy of:

irb(main):001:0> require ‘net/http’
=> true
irb(main):002:0> Net::HTTP.start(‘www.pragmaticprogrammer.com’) do
|http|
irb(main):003:1* response = http.get(‘/index.html’)
irb(main):004:1> puts “Code = #{response.code}”
irb(main):005:1> puts “Message = #{response.message}”
irb(main):006:1> response.each {|key, val| printf “%-14s =
%-40.40s\n”, key, val }
irb(main):007:1> p response.body[400, 55]
irb(main):008:1> end
Code = 200
Message = OK
last-modified = Tue, 30 Jan 2007 15:33:09 GMT
content-type = text/html; charset=iso-8859-1
etag = “b00d226-85d2-45bf6535”
date = Wed, 31 Jan 2007 09:36:07 GMT
server = Rapidsite/Apa/1.3.31 (Unix) FrontPage/5.
content-length = 34258
accept-ranges = bytes
"lling book ‘The Pragmatic Programmer’ and The\n "
=> nil

Good luck,

-Conrad

Thanks for pointing out the misspell problem.
I ran into this while

and finally got a true here.
And the Net::HTTP works fine.
So should I do something to fix the warnings?
