Small bug in net/http.rb

Eugene_Scripnik · 25 February 2003 10:22

I’ve played with Net::HTTP and found little mistype in proxy
authorization method (see attached diff).

I am still don’t know how to follow redirect to new dynamic web host on
the same real host. Is it possible with Net::HTTP?

Can you tell us the actual site you are testing?

With my module http-access2 (see RAA),
ruby -rhttp-access2
-e ‘p HTTPClient.new.getContent(“http://…”)’
should follow redirect(s). But the script you posted
with Net::HTTP should work as well I think.

ok, i’ll take a look at http-access2. try my script bellow - it fails
with message:
getaddrinfo: No address associated with hostname

fetch.rb:
#!/usr/local/bin/ruby -w

require ‘net/http’
require ‘uri’

uri = ‘http://www.sms.de/’
response = Net::HTTP.get_response( URI.parse( uri ) )
while Net::HTTPRedirection === response
puts response[‘Location’]
response = Net::HTTP.get_response( URI.parse( response[‘Location’] ) )
end
p response

Hmm, your sample fails on http://www.sms.de/, I don’t know why.

Interesting, here is my output:

How was compiled ruby ? which OS ?

Now www.sms.de use a cookie, and probably you need to propagate this
cookie.

This was just an example of not working code, I’ll resend cookies when I
get this code to work.

Well, I really don't know if it's IPv6 enabled try to compile ruby with

--enable-ipv6 --with-lookup-order-hack=INET

IPv6 networking is disabled in kernel on our server. And I don’t realy
understand how all this stuff works, but I can say that this script
works well if I use proxy instead of direct connection.
