[SOLVED] Parsing JSON feed with Ruby for use in Dashing Dashboard

Parsing JSON feed with Ruby for use in Dashing Dashboard

First post here, so ya know, be nice?

I'm setting up a dashboard in Dashing (http://dashing.io/) using a JSON feed on a server, which looks like:

{  
   "error":0,
   "message_of_the_day":"Welcome!",
   "message_of_the_day_hash":"a1234567890123456789012345678901",
   "metrics":{  
      "daily":{  
         "metric1":"1m 30s",
         "metric2":160
      },
      "monthly":{  
         "metric1":"10m 30s",
         "metric2":"3803"
      }
   },

I have been experimenting with grabbing the data from the feed, and have managed to do so by Python with no issues:

import json
import urllib2

data = {
        'region': "Europe"
}

req = urllib2.Request('http://192.168.1.2/info/handlers/handler.php')
req.add_header('Content-Type', 'application/json')

response = urllib2.urlopen(req, json.dumps(data))

print response.read()

However I haven't yet been successful, and get numerous errors in Ruby. Would anyone be able to point me in the right direction in parsing this in Ruby? My attempts to write a basic script, (keeping it simple and outside of Dashing) don't pull through any data.

#!/usr/bin/ruby
require 'httparty'
require 'json'

response = HTTParty.get("http://192.168.1.2/info/handlers/handler.php?region=Europe") 

json = JSON.parse(response.body)

puts json

Solution

In python code you are sending a JSON and adding a header. I bet it makes sense to do that in ruby as well. The code below is untested, since I can’t test it, but it should lead you into the right direction:

#!/usr/bin/ruby
require 'httparty'
require 'json'

response = HTTParty.post(
  "http://192.168.1.2/info/handlers/handler.php",
  headers: {'Content-Type', 'application/json'},
  query: { data: { 'region' => "Europe" } } 
  # or maybe query: { 'region' => "Europe" }
) 

puts response.inspect
