[BUG] Routing couldn't distinguish slashes even though I have the right regexp

[reedchan7]

Describe the bug

I want to combine multiple routes with slashes into a single parameter, like /*/suffix or /**/suffix, and /a/suffix, ab/cd/suffix, a1/b2/c3/d-4/suffix can match the rule, but it seems iris couldn't do this now (path is not suitable because I have other suffix like /a/b/c/suffix/another-suffix/and-more-suffix).

So, I wrote a regexp, and registered a custom macros, like this:

regex := regexp.MustCompile("^[a-z0-9/-]+$")
app.Macros().Get("string").RegisterFunc("name", regex.MatchString)

assert.True(t, regex.MatchString("abc/def/ghi"))

I thought this would work, and /ab/cd/ef/anything-else could match /{name:string name()}/anything-alse, but actually, it didn't!

It seems that al slashes couldn't combine to a single param, maybe except path.

Could you please tell me how to implement my requirement above? I am puzzled now..

To Reproduce Steps to reproduce the behavior:

1. register a custom macros:

regex := regexp.MustCompile("^[a-z0-9/-]+$")
app.Macros().Get("string").RegisterFunc("name", regex.MatchString)

2. register a routing:

app.Get("/{name:string name()}/balabala", helloWorldHandler)

3. try to get

curl localhost:8080/a/b/c/balabala
Not Found

Expected behavior

curl localhost:8080/a/b/c/balabala
hello, world!

and we could get the param name:

ctx.Params().Get("name")  // "a/b/c"
