Grails: Error while passing params via oauth tag to controller

I have following in my gsp:

<oauth:connect provider="facebook" params="[currentURL: location.protocol + '//'
            + location.host + location.pathname]">
    <img src="../images/socialSites/facebook.png" alt="facebook" />
</oauth:connect>

And following code in controller:

 def currentURL = params.currentURL
 println "currentURL is :"+currentURL;

and getting this error and page is not displayed:

Caused by: java.lang.NullPointerException: Cannot get property 'protocol' on null object

I read here that oauth can accept all params that g:link can accept, so trying to send current url to controller so as I can redirect to same page after login is successful. How do i make it happen?

You cannot add params to the connect tab of oauth taglib because it is not adding given params to the URL.

To achieve your requirement create your custom tag for authentication:

class MyOauthTagLib {

  static namespace = 'o'

  def connect = { attrs, body ->
    String provider = attrs.provider
    Map params = attrs.remove('params')

    if (!provider) {
        throw new GrailsTagException('No provider specified for <o:connect /> tag. Try <o:connect provider="your-provider-name" />')
    }

    Map a = attrs + [url: [controller: 'oauth', action: 'authenticate', params: [provider: provider] + params]]
    out << g.link(a, body)
  }
}

and use it in your gsp:

<o:connect provider="facebook" params="[currentURL: request.scheme + '://' + request.serverName + ':' + request.serverPort + request.forwardURI]">facebook</o:connect>

NOTE:- Use request as suggested by @Burt Beckwith. You cannot access location here.

location.protocol/location.host/location.pathname/etc. would work in JavaScript, but inside the params map only Groovy is supported, and that code has no access to the client-side state. Use

params="[currentURL: request.scheme + '://' + request.serverName + ':' + request.serverPort + request.forwardURI]"

instead.
