问题
I am using Openid4Java to implement Openid for my app on GAE. I am also using Shiro for security. The day before i had reached a stage where things were failing for credentials matching, i.e discovery, making auth request, getting claimed_id were all working. Yesterday all hell broke lose and since then discovery on Google is failing. things that i have verified:
- Yahoo is working fine (end to end)and
- Discovery for google is working fine on my local dev box(it ofcourse fails while returning to my localhost URL).
- The application on appengine has billing enabled so that internally Yadis can open socket connections.
I have tried the following discovery urls for Google: (some URLS below have spaces because i cant post more than 2 links). they are fine otherwise.
- https: //www.google.com/accounts/o8/id
- https: //www.google.com/accounts/o8/ud (https://developers.google.com/accounts/docs/OpenID?hl=es-ES#endpoint)
A few interesting logs before the stack trace:

the relying party code is pretty similar to the SampleConsumer (part of openid4java) but is actually a patch on shiro(openid4j). It seems to be in accordance with Sample Consumer.
Seems to me that i am missing something basic here. Any pointers will really help.
回答1:
It seems that the libraries you use are failing when trying to make connections to www.google.com:443.
Sockets API has quite a few limitations, most notably it does not allow connections to google servers (with some exceptions for email & DNS). This is a source of your errors.
If you want your app to use OpenID for auth then just use GAE provided APIs: https://developers.google.com/appengine/articles/openid
