Retrieving username from OpenID

Question

I use OpenID authentication in conjunction with traditional case / signature authentication on my site. When someone first signs up using OpenID, I would like to be able to retrieve the username for use on the site.

This is easy for some openid identifiers - for example:

http://username.myopenid.com/
http://username.livejournal.com/
http://claimid.com/username

However, this is not always the case, since any URL can essentially be used as an OpenID.

One option is to maintain a list of URL formats as described above, where I know that I can extract the username and automatically assign the username in other cases (which can be changed after logging in). Is there another, more flexible way to retrieve a username?

Answer 1

OpenID has an API for retrieving user information such as name, email address, etc. I would just use this name if the user allows you to access it.
