Question

How to build openID ReturnURL in gsp??

Define a ReturnURL

This is the endpoint where your webapp will receive and process the authentication responses from the OpenID Provider.

    String _returnURL = "http://example.com/openid";

Assuming that you have grails.serverURL set appropriately in your config.groovy file you can use the createLink tag with absolute set to true:

grails.serverURL = "http://example.com"

String _returnURL = createLink(controller:'openid', action:'handleReturn', absolute:true)

// _returnURL -> http://example.com/appname/openid/handleReturn
