Hi,
i’m usin ver 1.6.7 of ruby . Everytime I try to access a site via Net::HTTP
and this site has a 302 response code it says

/net/http.rb:1432: in error! : 302 “Found” (Net::ProtoRetriableError)

Ruby terminates the script with this errormessage. But I want to read out
the new location of the url. Does anybody know how to get this url or if
there is any possibility to solve this problem?

I don’t know about reading the “new” URL, but to prevent the program from
terminating, you should rescue Net::ProtoRetriableError. There’s probably a
superclass you can rescue as well. Let me see…

irb(main):001:0> require ‘net/http’
true
irb(main):003:0> Net::ProtoRetriableError.ancestors
[Net::ProtoRetriableError, Net::ProtocolError, StandardError, Exception,
Object, Kernel]

Yes, I’d rescue Net::ProtocolError, as in

begin
header, data = http.get(URL)
rescue Net::ProtocolError
STDERR.puts “HTTP retrieval failed”
end

Line 71 of /usr/local/lib/ruby/1.6/net/http.rb is your friend!

=== Redirect

require 'net/http'
Net::HTTP.version_1_1   # declear to use 1.1 features.

host = 'www.ruby-lang.org'
path = '/'
begin
  Net::HTTP.start( host, 80 ) {|http|
    response , = http.get(path)
    print response.body
  }
rescue Net::ProtoRetriableError => err
  if m = %r<http://([^/]+)>.match( err.response['location'] ) then
    host = m[1].strip
    path = m.post_match
    retry
  end
end
