Converting curl to ruby equivalent - ruby-on-rails

Question

I'm having trouble converting a curl to a ruby script. Basically I'm trying to consume the parse.com RESTful api. Here is the curl
curl -X POST \
-H "X-Parse-Application-Id: XXX" \
-H "X-Parse-REST-API-Key: YYY" \
-H "Content-Type: application/json" \
-d '{
"channels": [
"Giants",
"Mets"
],
"data": {
"alert": "test message"
}
}' \
https://api.parse.com/1/push
And this Is what I've been trying to do (using HttParty)
puts "hello world"
require 'httparty'
require 'json'
class Parse
include HTTParty
base_uri "api.parse.com:443"
headers "X-Parse-Application-Id" => "XXX", "X-Parse-REST-API-Key" => "YYY", "Content-Type" => "application/json"
end
option = {:channels => "Giants", :data => {:alert => "un mensaje de mierda"}}
puts Parse.post("/1/push", body: option.to_json)
)
I'm getting an error code 107 saying invalid json. Any suggestions will be appreciated.

I think you just need to serialise the ruby structure to JSON in the second param. The param should be the string to POST, not a Ruby struct.
I think this will work (only other possible problem I can see is whether you'll connect via https as the code is written):
data = {"channels": ['Giants'], "data": {alert: 'un mensaje '}}
puts Parse.post("/1/push", body: data.to_json)
. . . the JSON-like format in the Ruby data structure is not JSON,
foo: "bar"
is just another Ruby (1.9+) way of saying
:foo => "bar"
