I've not used Gin, but it should be pluggable as a normal HTTP middleware

You can do it like this @jkgeekJack

const casURL = ""

func Auth() gin.HandlerFunc {
	url, _ := url.Parse(casURL)
	client := cas.NewClient(&cas.Options{URL: url})
	handler := client.HandleFunc(func(writer http.ResponseWriter, request *http.Request) {
		// DO NOTHING
	})

	return func(ctx *gin.Context) {
                 // Call the normal method 
		handler.ServeHTTP(ctx.Writer, ctx.Request)

		if !cas.IsAuthenticated(ctx.Request) {
			// redirect to login url
                         ctx.Abort()
		}
		ctx.Next()
	}
}
