How to do URL mapping in Crafter 3.0

Question

I was wondering if crafter (3.0) has the ability to do url mapping.

For example, to have a content at a given path like /site/website/foobar/mycontent/index.xml, and its url being /news/2017/11/17/my-content (notice the added / which can't be used in a file-name field since they are automatically converted to - in studio).

Thanks,

A built-in router is on our roadmap (https://github.com/craftercms/craftercms/issues/1622), but for now, you can add one to your blueprint easily:

1. Create a component that contains a "routing table". This component has a repeating table where each entry is an inbound URL and outbound URL.

2. Create a Groovy filter script that will intercept all calls and checks if the URL matches one of the inbound URLs. If it does, it forwards the request to the corresponding outbound URL. Below is the possible code for such filter:

   def routingTableItem = siteItemService.getSiteItem("/site/components/system/routing-table.xml")
   def routingTable = routingTableItem.urlRoutingTable.item
   def currentURL = request.requestURI
   
   def matchedEntry = routingTable.find { entry ->
       return currentURL == entry.inboundURL.text
   }
   
   if (matchedEntry) {
       def inboundURL = matchedEntry.inboundURL.text
       def outboundURL = matchedEntry.outboundURL.text
   
       logger.info("Forwarding URL ${inboundURL} to ${outboundURL}")
   
       request.getRequestDispatcher(outboundURL).forward(request, response)
   } else {
       filterChain.doFilter(request, response)
   }
