Is there a way to set the expected request content type for a route? I have a route that looks like this:

["notify/" {:post {:name "notify"
                          :tags ["api" "aws"]
                          :summary "receive notifications from AWS"
                          :parameters {:body [:map
                                              [:Type :string]
                                              [:MessageId :string]
                                              [:TopicArn :string]
                                              [:Message :string]
                                              [:Timestamp :string]
                                              [:SignatureVersion :string]
                                              [:Signature :string]
                                              [:SigningCertUrl :string]
                                              [:UnsubscribeUrl :string]]}
                          :responses {200 {:body [:map
                                                  [:message :string]]}}
                          :handler ping}}]
