title: Get a JSON as POST parameter
body: <p>I have a ruby application and I need to receive a JSON from a client. Receiving a JSON is just like receiving a string? I just have to do something like:</p>
  
  <pre><code>information = params[:json_data]
  data_parsed = JSON.parse(information)
  </code></pre>
  
  <p>That's all or I have to do something different when getting a JSON? The sender has to send me that like string?</p>
  
  <p>Thanks!</p>
