Question

Hi guys I have a python script that posts some data to google and gets back response. The script is below

net, cid, lac = 24005, 40242, 62211
import urllib
a = '000E00000000000000000000000000001B0000000000000000000000030000'
b = hex(cid)[2:].zfill(8) + hex(lac)[2:].zfill(8)
c = hex(divmod(net,100)[1])[2:].zfill(8) + hex(divmod(net,100)[0])[2:].zfill(8)
string = (a + b + c + 'FFFFFFFF00000000').decode('hex')
try:
  data = urllib.urlopen('http://www.google.com/glm/mmap',string)
  r = data.read().encode('hex')
  print r
except:
  print 'connect error'

I want to get the same response with a ruby script. I am not able to form the request properly and I always get the badimplementation error or http 501 error. Could you tell me where the mistake is at? (The ruby script is attached below).

require 'net/http'
def fact(mnc,mcc,cid,lac)
  a = '000E00000000000000000000000000001B0000000000000000000000030000'
  b = cid.to_s(16).rjust(8,'0') + lac.to_s(16).rjust(8,'0')
  c = mnc.to_s(16).rjust(8,'0') + mcc.to_s(16).rjust(8,'0')
  string = [a + b + c + 'FFFFFFFF00000000'].pack('H*')
  url = URI.parse('http://www.google.com/glm/mmap')
  resp = Net::HTTP.post_form(url,string)
  print resp
end
puts fact(5,240,40242,62211)

Answer 1

From the documentation:

Posts HTML form data to the specified URI object. The form data must be provided as a Hash mapping from String to String.

You have to pass the parameters, if I understood that correctly, on the form:
{"param1" => "value1", "param2"=>"value2"}

I just didn’t understand what are the names of the parameters you are passing on your request.

Here are some usage examples for the method Net::HTTP::post_form, also from the official doc:

Ex 1:

uri = URI('http://www.example.com/search.cgi')
res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50')
puts res.body

Ex2:

uri = URI('http://www.example.com/search.cgi')
res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50')
puts res.body

Link to the examples

Hope it helps

edit: function that accepts a String as a parameter to the post request: Net::HTTP::request_post
