如何将COR添加到compojure api应用程序?

(def app
    (api
        {:swagger {:ui   "/docs"
                   :spec "/swagger.json"}}

       (GET "/route-a" [] "a")
       (GET "/route-b" [] "b")
       (GET "/route-c" [] "c")))

我想用 https://github.com/r0man/ring-cors

(-> (api
   {:swagger {:ui   "/docs"
              :spec "/swagger.json"}}

   (GET "/route-a" [] "a")
   (GET "/route-b" [] "b")
   (GET "/route-c" [] "c"))

  (wrap-cors :access-control-allow-origin #"http://localhost:81"
             :access-control-allow-headers ["Origin" "X-Requested-With"
                                        "Content-Type" "Accept"]
             :access-control-allow-methods [:get :put :post :delete :options]))
