 6     $jumpurl = $weixin->oauth2_authorize($redirect_url, "snsapi_base", "123");
 7     Header("Location: $jumpurl");
 8     exit;
 9 }else{
10     $access_token = $weixin->oauth2_access_token($_GET["code"]);

12     $info = $weixin->get_user_info($openid);
13     if ($info["subscribe"] == 1){
14         $href = "http:// www.baidu.com/";
15     }else{
16         $href = "http:// mp.weixin.qq.com/s?__biz=MzA5NzM2MTI4OA==&mid=203240737&
           idx=1&sn=007bbbe06fb89cbce76d6f8b619acc1a&scene=0#wechat_redirect";
