應用程序池采用.Net Framework 4.0

注意IIS綁定的域名,兩個完全不同域的域名。



數據庫采用EntityFramework6.0.0,首次運行會自動創建相應的數據庫和表結構。
在瀏覽器地址欄中訪問:http://app.com,如果用戶還未登陸則網站會自動重定向至:http://sso.com/passport,同時通過QueryString傳參數的方式將對應的AppKey應用標識傳遞過來,運行截圖如下:
URL地址:http://sso.com/passport?appkey=670b14728ad9902aecba32e22fa4f6bd&username=

輸入正確的登陸賬號和密碼后,點擊登陸按鈕系統自動301重定向至應用會掉首頁,毀掉成功后如下所示:

由于在不同的域下進行SSO授權登陸,所以采用QueryString方式返回授權標識。同域網站下可采用Cookie方式。由于301重定向請求是由瀏覽器發送的,所以在如果授權標識放入Handers中的話,瀏覽器重定向的時候會丟失。重定向成功后,程序自動將授權標識寫入到Cookie中,點擊其他頁面地址時,URL地址欄中將不再會看到授權標示信息。Cookie設置如下:

登陸成功后的后續授權驗證(訪問其他需要授權訪問的頁面):
校驗地址:http://sso.com/api/passport?sessionkey=xxxxxx&remark=xxxxxx
返回結果:true,false
客戶端可以根據實際業務情況,選擇提示用戶授權已丟失,需要重新獲得授權。默認自動重定向至SSO登陸頁面,即:http://sso.com/passport?appkey=670b14728ad9902aecba32e22fa4f6bd&username=SEO@ljja.cn 同時登陸頁面郵箱地址文本框會自定補全用戶的登陸賬號,用戶只需輸入登陸密碼即可,授權成功后會話有效期自動延長一年時間。
用戶授權驗證日志:

用戶授權會話Session:
