本文给出了openid登录的源代码，以与大家共享。

以前sipo好像说asp写openid有些不能解决的问题，我也没查openid的规范。

这个对付简单的登录还是没问题的，不过代码还没测试。先放上来，有兴趣的可以看看

<script language="JScript" runat="server">

Response.Redirect(returnUrl); }else{ if(input["openid"]==""||input["return"]==""){ Response.write("<sc"+"ript>"); Response.write("alert(\"error\");"); Response.write("window.history.forward(1);"); Response.write("</sc"+"ript>"); Response.end(); } openid.url = input["openid"]; openid.get(); }
