整合OpenID範例

A simple OpenID authentication example

This example provides a high-level view of how OpenID authentication can be used within a Play! application:

    * 檢查每組請求用戶是否連接
    * 用戶可提交自己的OpenID來顯示頁面
    * 將用戶重定轉向至OpenID provider
    * 當用戶返回，得到驗證的OpenID並儲存於HTTP session

The OpenID functionality is provided by the play.libs.OpenID class and is build using http://code.google.com/p/openid4java/|OpenID4Java.
