title: Flask and Swagger UI does not work?
body: <p>I am trying to create a RESTful app using Flask and swagger. But when I run the endpoint I do not see the methods documented in the browser like described here for example <a href="http://michal.karzynski.pl/blog/2016/06/19/building-beautiful-restful-apis-using-flask-swagger-ui-flask-restplus/" rel="nofollow noreferrer">http://michal.karzynski.pl/blog/2016/06/19/building-beautiful-restful-apis-using-flask-swagger-ui-flask-restplus/</a> 
  Instead just the <code>404 not found</code> error. Here is my code:</p>
  
  <pre><code>def init_deserializer_restful_api():
      # Get port number for the web app.
      PORT = 8000
  
      # Initiate the Flask app
      app = Flask(__name__)
      Swagger(app)
      CORS(app)
  
      # Handler for deserializer
      @app.route("/deserialize", methods=['POST','GET'])
      def handle_deserialization_request():
      # Method description
      # Method content
  </code></pre>
  
  <p>App is run like this:</p>
  
  <pre><code>app.run(port=PORT, host="0.0.0.0")
  </code></pre>
  
  <p>I run <code>http://localhost:8000/deserializer</code> I get <code>The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again</code>.</p>
  
  <p>Questions:
  1. How do I feed flask the request.json it requires?
  2. How do I get swagger to work?</p>
