    r := mux.NewRouter()

    r.PathPrefix("/swagger/").Handler(httpSwagger.Handler(
        httpSwagger.URL("http://localhost:1323/swagger/doc.json"), //The url pointing to API definition
        httpSwagger.DeepLinking(true),
        httpSwagger.DocExpansion("none"),
        httpSwagger.DomID("#swagger-ui"),
    )).Methods(http.MethodGet)
