title: converting json into jsonp for using it as a callback
body: <p>I am trying to use a data api. I am still at a very preliminary stage with this so just digging in to understand the basic plumbing. I id some research to check whatare the variables involved and i found out that I have to have some sort of server side scripting to handle cross domain call for json. Basically to convert it into jsonp. Now the the qestion is how. I looked but dont really see a direction which matches my requirement.</p>
  
  <p>Here is the api which is returning in  .json </p>
  
  <p><a href="http://data.cityofnewyork.us/resource/xm9j-adfx.json" rel="nofollow">http://data.cityofnewyork.us/resource/xm9j-adfx.json</a></p>
  
  <p>And here is a code sample:</p>
  
  <pre><code>[ {
    "consumption_gj_" : "83983",
    "zip_code" : {
      "needs_recoding" : false,
      "longitude" : "-73.99688630375988",
      "latitude" : "40.75025902143676",
      "human_address" : "{\"address\":\"\",\"city\":\"\",\"state\":\"\",\"zip\":\"10001\"}"
    },
    "building_type_service_class_" : "Commercial"
  }
  , {
    "consumption_gj_" : "91967",
    "zip_code" : {
      "needs_recoding" : false,
      "longitude" : "-73.98583147024613",
      "latitude" : "40.71612146793143",
      "human_address" : "{\"address\":\"\",\"city\":\"\",\"state\":\"\",\"zip\":\"10002\"}"
    },
    "building_type_service_class_" : "Commercial"
  } ]
  </code></pre>
  
  <p>lets say I would like to print all the zip codes from here</p>
  
  <p>How should I approach this? </p>
