如何在GSP中使用openid4java實現openID

Question

如何在gsp中構建openID的ReturnURL？

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";

假設你有grails.serverURL在你的Config.groovy文件中適當設置就可以使用絕對集建立連結標記爲true：

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

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

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