User Agent String

Ruby
1

Hey guys,

I want my Ruby script to make a request to a server but I don’t want it
to use just the basic User Agent String. How would I go about giving my
script a User Agent string to use?

I would suggest posting what you already have and we’ll go from there.

Hi,

How about:

require ‘net/http’
user_agent = “you can set this part”
h = Net::HTTP.new(‘www.example.com’, 80)
resp, data = h.get(‘/index.html’, {“User-Agent”=>user_agent})

Net::HTTP#initialize takes a host and a port, not URI and port:

$ ruby
require ‘net/http’
h = Net::HTTP.new ‘google.com’, ‘http’
resp, data = h.get ‘/’, “User-Agent” => “Ruby/#{RUBY_VERSION}”
p resp, data
#<Net::HTTPOK 200 OK readbody=true>
“[…]<input name=btnI type=submit value="I’m Feeling Lucky">[…]”
$

Putting that into irb gives me:
=> [#<Net::HTTPBadRequest 400 Bad Request readbody=true>, “\n\n400 Bad
Request\n\n

Bad Request

\nYour browser sent
a request that this server could not understand.

\nClient sent
malformed Host header

\n\n”]

I’ve had some luck with open-uri, but I still want to get the error
code’s from the site. I would really like to be able to create generic
HTTP requests, but it’s quite daunting.

I’ve tried the above with the following:
user_agent = ‘Ruby Net::HTTP’
print “Getting h\n”
h = Net::HTTP.new(‘http://www.google.com’, 80)
print “getting response\n”
resp, data = h.get(‘/’, {“User-Agent”=>user_agent})
print data.body
print resp
print “should’ve printed\n”

and all it gives me is:
SocketError: getaddrinfo: No address associated with nodename
