body: <p>Here is the sample string i am receiving from one of the web services,</p>
  
  <pre><code>body=%7B%22type%22%3A%22change%22%2C%22url%22%3A%22http%3A%2F%2Fapi.pachube.com%2Fv2%2Ftriggers%2F4100%22%2C%22environment%22%3A%7B%22feed%22%3A%22http%3A%2F%2Fapi.pachube.com%2Fv2%2Ffeeds%2F36133%22%2C%22title%22%3A%22Current+Cost+Bridge%22%2C%22description%22%3Anull%2C%22id%22%3A36133%7D%2C%22threshold_value%22%3Anull%2C%22timestamp%22%3A%222012-01-05T09%3A27%3A01Z%22%2C%22triggering_datastream%22%3A%7B%22url%22%3A%22http%3A%2F%2Fapi.pachube.com%2Fv2%2Ffeeds%2F36133%2Fdatastreams%2F1%22%2C%22value%22%3A%7B%22value%22%3A%22523%22%2C%22max_value%22%3A1269.0%2C%22min_value%22%3A0.0%7D%2C%22id%22%3A%221%22%2C%22units%22%3A%7B%22symbol%22%3A%22W%22%2C%22type%22%3A%22derivedUnits%22%2C%22label%22%3A%22watts%22%7D%7D%2C%22id%22%3A4100%7D
  </code></pre>
  
  <p>Here is the code,</p>
  
  <pre><code>class Feeds():
      def GET(self):
          print "Get request is accepted."
          return render.index(None)
  
      def POST(self):
          print "Post request is accepted."
          print (web.data())
  </code></pre>
  
  <p>Now when that web-service posts the above given data, how will i convert it to readable format? Then, i need to convert it to JSON object and use further. So, how will i convert it?</p>
  
  <p>When i try this code,</p>
  
  <pre><code>        json_data = json.loads(web.data())
          print json_data['body']
          return render.index(json_data['body'])
  </code></pre>
  
  <p>It gives me an error,</p>
  
  <pre><code>enter code Traceback (most recent call last):
