title: Grails send request as JSON and parse it in controller
body: <p>I want to send a request as JSON and in my controller I want to parse this JSON and get the parameters I want. for example this is the request:</p>
  
  <pre><code>{"param1":"val1"}
  </code></pre>
  
  <p>I want to parse this request and get "param1" value. I used request.JSON but still I got null. Is there any other way to solve this?</p>
  
  <p>Thanks,</p>
