Parse many path

[junjielu]

Hello,
I have encountered a problem in the process of using it and would like to ask for advice.

Here is the input:
https://apps.apple.com/xx/xx/xx/id{product_id}
or maybe:
https://apps.apple.com/xx/xx/id{product_id}
even:
https://apps.apple.com/xx/id{product_id}

I would like to know if there is a way to parse the product id in the link?
Thanks a lot.

In order to do this you will need to add a product_id parser for each route along the way.
This is how I would do it. I hope it help. @junjielu

import URLRouting
import Foundation

enum AppRoute {
  case foo(FooRoute)
}

enum FooRoute {
  case id(String)
  case bar(BarRoute)
}

enum BarRoute {
  case id(String)
  case zurg(String)
}

let idParser = Parse {
  "id"
  Parse(.string)
}

let barRouter = OneOf {
  Route(.case(BarRoute.id)) {
    Path { idParser }
  }

  Route(.case(BarRoute.zurg)) {
    Path { "zurg"; idParser }
  }
}

let fooRouter = OneOf {
  Route(.case(FooRoute.id)) {
    Path { idParser }
  }
  
  Route(.case(FooRoute.bar)) {
    Path { "bar" }
    barRouter
  }
}

let appRouter = OneOf {
  Route(.case(AppRoute.foo)) {
    Path { "foo" }
    fooRouter
  }
}
