如何在Golang路由中将URL作为参数传递？

Question

I'm trying to pass a URL as a parameter in Golang, and I haven't been able to find a solution in all of the tutorials I've looked at. The problem is that I can only get the url to return minus a crucial forward slash.

My handler looks like this:

router.HandleFunc("/new/{url}", createURL)

So the request would look like:

www.myapp.heroku.com/new/https://www.google.com

However, the url that I results is missing a slash:

http:/www.google.com

I sure it's probably got something to do with RFC3986, but is there a way to pass in the url as it is?

This particular behavior in Gorilla Mux can be changed by setting SkipClean to true.

router := mux.NewRouter()
router.SkipClean(true)
router.HandleFunc("/new/", index)
router.HandleFunc("/", index)
http.ListenAndServe(":"+port, router)

The relevant documentation can be found here.
