title: Accepting multiple parameters in flask-restful add_resource()
body: <p>I want to handle a GET request in my Flask REST API. The request will include multiple parameters, and you can expect this to be a typical GET request:
  <a href="https://localhost:5000/item/analysis=true&amp;class=A&amp;class=B" rel="noreferrer">https://localhost:5000/item/analysis=true&amp;class=A&amp;class=B</a></p>
  
  <p>Thus, a GET request consists of: </p>
  
  <ol>
  <li>a Boolean variable called "analysis"</li>
  <li>a list called "class"</li>
  </ol>
  
  <p>I want to accept this inside an add_resource() as follows: </p>
  
  <p><code>add_resource(Item, '/item/&lt;whatever-comes-here&gt;')</code></p>
  
  <p>I am clueless about how I would accept multiple parameters (one of them being a list) inside the add_resource(). How do I accept them in the add_resource() function and how do I unpack them inside the get() function?</p>
  
  <p>I have spent time reverse engineering this, but I have not yet been successful. Am I doing something wrong? </p>
  
  <p>(I understand that there might be a better way to send lists with a REST API GET request, so I'd appreciate any pointers regarding that!)
  Sincere thanks in advance!</p>
