title: QueryDict to string loses list within JSON
body: <p>My request is of type QueryDict and I want to convert it to a JSON object or string so I can validate it against a JSON schema. One of the JSON fields contains a list, like so:</p>
  
  <pre><code>{
  "message": "Hello!",
  "people": ["Aaron", "Randy", "Chris", "Andrew"]
  }
  </code></pre>
  
  <p>When I convert it to a string using json.dumps(), get the following:</p>
  
  <pre><code>'{"message": "Hello!", "people": "Andrew"}'
  </code></pre>
  
  <p>What is the best way to go about dealing with this situation?</p>
