How to get OpenID user Profile info?

Question

After logging into SO, my nickname shows up at the top.

When I set up openid on my site, I do not get any profile information.

I tried implementing OpenID using openid-selector and Zend Framework

The response parameters I get:

openid.assoc_handle B2Jgsdf7jkDsdfUwWBGMHUshLmavymH...
openid.claimed_id   https://me.yahoo.com/MyYahooId#50a9f
openid.identity https://me.yahoo.com/MyYahooId
openid.mode id_res
openid.ns   http://specs.openid.net/auth/2.0
openid.ns.pape  http://specs.openid.net/extensions/pape/1.0
openid.op_endpoint  https://open.login.yahooapis.com/openid/op/auth

What is the reason I do not receive profile information such as nickname? When SO uses openid-selector, how does it get the nickname?

Any information aside from claimed_id and endpoint URL must be retrieved via Simple Registration (SREG) or Attribute Exchange (AX) extensions to OpenID.

You must explicitly request for them when asking for authentication.

Zend's consumer SREG documentation can be found here: http://framework.zend.com/manual/en/zend.openid.consumer.html#zend.openid.consumer.sreg

Note that these information are not guaranteed, and providers are given the freedom to decide (with or without user input) to withhold any and all requested information, or not support them outright.

Google implements AX as well as Yahoo (you have to request permission from yahoo). Unfortunately Zend Framework OpenID only supports SREG at the time of this writing but I've written an extension for AX support here as well ak33m.com/?p=71 – Garotte

I was using SREG but it did not return any info. – Verse

SREG and AX information is not guaranteed. The choice to provide information requested via these extensions is always in the hands of the user and OpenID provider. – Urticaria
