QQ登陆代码

HTML文件中放置QQ登陆按钮

 <a href="redirect.asp" target=_self  data-role="button" class="ui-btn-right" style="height:24px;line-height:24px;"><img src="Images/bt_blue.png" height="24" alt="QQ登录" border="0"></a>

Redirect.asp文件内容如下：

<!--#include file="qqconnect.asp"-->
<%
Dim qc, url
    Session("Code")=""
    Session("Openid")=""
    Session("Access_Token")=""
SET qc = New QqConnet
    Session("State")=qc.MakeRandNum()
    url = qc.GetAuthorization_Code()

    Response.Redirect(url)
Set qc=Nothing

%>

qqconnect.asp内容如下：

<script language="jscript" runat="server">
function getjson(str){
        try{
           eval("var jsonStr = (" + str + ")");
        }catch(ex){
           var jsonStr = null;
        }
