【问题描述】：

Paypal 通过静默 url 定期订阅在真实账户上给出无效响应和空白状态和订阅 ID，但这适用于沙盒账户。

string cmd = "_xclick-subscriptions";
        string redirect = "";        
        redirect += "?cmd=" + cmd;
        redirect += "&business=" + businessEmail;
        redirect += "&item_name=" + lblDesc.Text.Trim();        
        redirect += "&no_shipping=" + "2";
        redirect += "&no_note=" + "1";
        redirect += "&currency_code=" + "USD";
        redirect += "&lc=" + "";        
        redirect += "&return=" + successPage;
        redirect += "&cancel_return=" + FailurePage;
        redirect += "notify_url=" + successPage;
        redirect += "&rm=" + "2";
        //for first month free count=1
        redirect += "&a1=" + "0.0";
        redirect += "&p1=" + count.ToString();
        redirect += "&t1=" + "M";
        //new added parameter for recurring
        redirect += "&a3=" + total;
        redirect += "&p3=" + count.ToString();
        redirect += "&t3=" + "M";
        redirect += "&src=" + "1";
        redirect += "&sra=" + "1";      

        return "https://www.paypal.com/cgi-bin/webscr"+ redirect;

得到回应

【问题讨论】：

您是指当您被发送到 PayPal 时得到一个空白页面，还是当您被重定向回您的站点时得到一个空白页面？
是的，当我从贝宝返回时，没有任何价值。

【解决方案1】：

如果您尝试使用 PDT 获取响应然后转身验证，请确保您的帐户中启用了 PDT 并设置了返回 URL。然后尝试删除返回 url 和传递的 rm 变量的代码行。
