Just starting to dabble with Ruby and XML, initial attempts at using
HTTParty have been amazing, so I'm starting to port some of my
clunkier scripts to Ruby... and now I've run into something that's got
me stumped...

I'm trying to submit a request to Google's location API, (Request
format defined at http://code.google.com/p/gears/wiki/GeolocationAPI?redir=1).
I'm currently doing this via curl, with a command like:

curl http://www.google.com/loc/json -H "Pragma: no-cache" -H "Cache-
control: no-cache" -d
'{"version":"1.1.0","host":"maps.google.com","request_address":true,"addres s_language":"en_GB","wifi_towers":
[{"mac_address": "xx-xx-xx-xx-xx-xx", "signal_strength": -81,"age":
0}]}'

Usually I have multiple WIFI access points defined in the
"wifi_towers" section, but I'm trying to simplify here.

Anyway, I'm trying to port this to Ruby, and what I have so far is:
--------------------------------------------------------------------------- ------------------------
#!/usr/bin/ruby

require 'rubygems'
require 'httparty'

class GeoLocate
        include HTTParty
        debug_output $stdout
        format :json
        base_uri 'http://www.google.com'
        headers "Pragma" => "no-cache", "Cache-controle" => "no-cache"
end

queryHash = {}

queryHash['version']='1.1.0'
queryHash['host']='maps.google.com'
queryHash['request_address']=true
queryHash['address_language']='en_GB'
queryHash['wifi_towers']={"signal_strength" => -57, "mac_address" =>
"00-24-6c-a9-01-51"}

result = GeoLocate.post('/loc/json',:body => queryHash)
--------------------------------------------------------------------------- ------------------------

If I pp the queryHash, that looks like what I'm expecting:

{"address_language"=>"en_GB",
 "version"=>"1.1.0",
 "request_address"=>true,
 "host"=>"maps.google.com",
 "wifi_towers"=>{"signal_strength"=>-57, "mac_address"=>"00-24-6c-
a9-01-51"}}

However, when I post that to Google, I get the following response:

--------------------------------------------------------------------------- ------------------------

JSON parsing error.

--------------------------------------------------------------------------- ------------------------

I suppose I could just run curl in the background to get the results,
but I'd really like to start using Ruby object instead of just
dropping to bash commands all the time, not to mention I love how easy
it is to parse the results once HTTParty sorts things out.

Anyway, forgive me if my newby status is making me miss something
glaringly obvious, I'm really hoping that someone out there has an
idea of what I'm missing though.

Thanks in advance,

Jeff

Wow, thanks for the quick response Sandro, you definitely got me to the next phase.  

Changing the "result = ...." line to:

result = GeoLocate.post('/loc/json', :body => JSON.dump(queryHash))

I now get a result in the debug log, but not into the "result" variable... changing the line again to

result = GeoLocate.post('/loc/json', :body => JSON.dump(queryHash)).body

does get me the result, but as a string not a hash or array, so it's not getting parsed by HTTParty.

The result I get looks like:

"{\"location\":{\"latitude\":##.#######,\"longitude\":-###.########,\"accur acy\":64.0},\"access_token\":\"2:Mkgg_dsFWPniHolX:4nG3UXVLT27ndr4P\"}"

(* Lat and Long  results redacted)

Any more ideas?  I suppose I could start working on parsing it out manually, but definitely nicer if HTTParty does it for me (I'm lazy I guess)

OK, that does the trick, I suspect if I wasn't such a newbie at this it probably would have been glaringly obvious.  Thanks for the help!!
