Nuby problem with net/http

Hello

I am trying to do some basic http stuff with Ruby but I can’t get the
following example from the Programming Ruby book to work.

Code from the book:

require ‘net/http’

h = Net::HTTP.new(‘www.pragmaticprogrammer.com’, 80)
resp, data = h.get(‘/index.html’, nil )
puts “Code = #{resp.code}”
puts “Message = #{resp.message}”
resp.each {|key, val| printf “%-14s = %-40.40s\n”, key, val }
p data[0…55]

I get this error:

c:/ruby/lib/ruby/1.8/net/protocol.rb:83:in initialize': getaddrinfo: no address associated with hostname. (SocketError) from c:/program files/ruby/lib/ruby/1.8/net/protocol.rb:83:in new’

from http_msg.rb:4

Exit code: 1

Details:
Ruby: version 1.8.1 (2004-01-27)
OS: Win XP Pro
I’m behind a proxy with the only information I have about it are IP
address and port number.

Many thanks for your help!

Hello kris

Hello

I am trying to do some basic http stuff with Ruby but I can’t get the

Code from the book:

require ‘net/http’

h = Net::HTTP.new(‘www.pragmaticprogrammer.com’, 80)

maybe yout try here
h = Net::HTTP.new(‘www.pragmaticprogrammer.com’,80,‘p-addr’, ‘p-port’)
p-addr: the addresss of your proxy
p-port: the port of your proxy

resp, data = h.get(‘/index.html’, nil )
puts “Code = #{resp.code}”
puts “Message = #{resp.message}”
resp.each {|key, val| printf “%-14s = %-40.40s\n”, key, val }

Hello

I am trying to do some basic http stuff with Ruby but I can’t get the
following example from the Programming Ruby book to work.

Code from the book:

Note that a couple of things have changed in Net::HTTP since the book came
out, see changes below:

require ‘net/http’

h = Net::HTTP.new(‘www.pragmaticprogrammer.com’, 80)
resp, data = h.get(‘/index.html’, nil )

HTTP#get now only returns a single Net::HTTPResponse object, but don’t
worry, you can still get at the data (Or body of the page) by doing:

resp = h.get(‘/index.html’,nil)
puts resp.body

puts “Code = #{resp.code}”
puts “Message = #{resp.message}”
resp.each {|key, val| printf “%-14s = %-40.40s\n”, key, val }
p data[0…55]

I get this error:

c:/ruby/lib/ruby/1.8/net/protocol.rb:83:in initialize': getaddrinfo: no address associated with hostname. (SocketError) from c:/program files/ruby/lib/ruby/1.8/net/protocol.rb:83:in new’

It’s not working because you’re behind a firewall. You need to use a
proxy like so:

require 'net/http'
proxy_addr = 'your.proxy.host'
proxy_port = 8080
        :
Net::HTTP::Proxy(proxy_addr, proxy_port).start('www.example.com')

{|http|
# always connect to your.proxy.addr:8080
:
}
