title: retrieve data from post requests in the form of JSON structure
body: <p>I am working on app engine in python, with a handler to response the post requests from javascript, the post requests are sent in JSON structure, in firebug console window, the Http request is shown: </p>
  
  <pre><code>[{"name":"John","value":"student"},{"name":"Mike","value":"teacher"}]
  </code></pre>
  
  <p>Can anyone tell me how to get this JSON data off the post requests in the handler?
  thanks in advance.</p>
