问题
I am trying to implement OpenID as one preferred option to my next web app here
The code is taken from this tutorial and works if I use my openID from myopenid.com
However, I believe most people would just love to use their everyday email address as their openID, as far as I know, Google, Yahoo, and some other big players have already done this in their systems.
My question is: how could I find the correct "url" to enter in the form to login? I used my Google OpenID account for StackOverflow and it works just fine. I try to copy my openID like this:
www.google.com/accounts/o8/id?id=aitoawllano10bzdzp3ht0diffry0qt6_j2ls-m
And paste it directly into my form, but it doesn't work.
I also tried to remove the url parameter, but that won't do, either.
Thanks a lot in advance for any tips and suggestions.

Basically, you're not allowed to use a token produced for one site to authenticate to another. This is a security feature. (OK, the site which is allowed to see the OpenID identity could make an assertion accepted by the other site about your identity, but that's out-of-band w.r.t. OpenID.)
The URL you should use is just this:
https://www.google.com/accounts/o8/id
