Grails URL Mapping and slash character in URL

grails, url

Solution

URL mappings can use `$paramName**` to allow slashes within a particular parameter - this is typically used with something like a CMS where you want to map a whole virtual path hierarchy to a single controller, but it could be useful in your case too.

"/api/clientQuote/$labcode/$cliCode/$quoCode**"(controller: "clientQuote") {
  action = [GET: "get"]
}

This would permit `http://myapp.com:9090/CCLASService/api/clientQuote/BRMIN/CL-000236/QT-000965/0-0` even without the slash escaped.

Problem

I'm facing the following problem: My Grails (2.2.0) app has the following URL Mapping: ``` "/api/clientQuote/$labcode/$cliCode/$quoCode"(controller: "clientQuote") { action = [GET: "get"] } ``` Let's suppose the following values: ``` $labcode = BRMIN $cliCode = CL-000236 $quoCode = QT-000965/0-0 ``` Since $quoCode has a slash character, it's necessary to replace it for %2F. This way, a possible URL could be: http://myapp.com:9090/CCLASService/api/clientQuote/BRMIN/CL-000236/QT-000965%2F0-0 When I put this URL in any browser a blank screen is showed as return. It's strange because the request doesn't even reach my Grails controller. For other side, if I change the url for: http://myapp.com:9090/CCLASService/clientQuote/get?labcode=BRMIN&cliCode=CL-000236&quoCode=QT-000965%2F1-0 Everything works fine, I receive a correct XML response to my request. The question is: Why when I use a specific URL Mapping with a encoded character I receive a blank screen as return?
