如何在GSP中使用openid4java实现openID

Question

如何在gsp中构建openID 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";

假设您在config.groovy文件中适当地设置了grails.serverURL，您可以使用绝对设置为true的createLink标记：

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

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

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