c# - Asp.net Paypal 返回 Url 要求

Question

我正在为我的测试程序使用 asp.net。

//string Server_URL = "https://www.paypal.com/ph/cgi-bin/webscr?";
            string Server_URL = ConfigurationManager.AppSettings["URL"].ToString();

            //Assigning Cmd Path as Statically to Parameter
            string cmd = "_xclick";

            //Assigning business Id as Statically to Parameter
            string business = ConfigurationManager.AppSettings["BusinessName"].ToString();

            //Assigning item name as Statically to Parameter
            string item_name = lblProductCode.Text;

            //Passing Amount as Statically to parameter 
            double amount = Convert.ToDouble(_lblPrice.Text);
            Session["Amount"] = amount;

            //Passing Currency as Statically to parameter
            string currency_code = "PHP";

            string redirect = "";

            //Pass your Server_Url,cmd,business,item_name,amount,currency_code variable.        
            redirect += Server_URL;
            redirect += "cmd=" + cmd;
            redirect += "&business=" + business;
            redirect += "&first_name=" + Session["id"].ToString();
            redirect += "&item_name=" + item_name;
            redirect += "&amount=" + amount;
            redirect += "&quantity=1";
            redirect += "&currency_code=" + currency_code;

            redirect += "&return=http://localhost:49457/Fun/Success.aspx";
            redirect += "&cancel_return=" + ConfigurationManager.AppSettings["FailedURL"].ToString();

            Session["Redirect"] = redirect;

            Response.Redirect(redirect);

现在在网站支付首选项中我在我的代码中将返回 URL 设置为相同。它说“我们无法验证您输入的 URL。请检查您的输入并重试。”

是否可以在返回 url 中插入本地主机 url？？？

我曾经这样做过，它适用于本地服务器测试:

protected void imgBtnBuyNow_Clicked(object sender, EventArgs e)
{
    string redirecturl = "";

    //Mention URL to redirect content to paypal site
    redirecturl += "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_xclick&business=" + ConfigurationManager.AppSettings["paypalemail"].ToString();

    //First name i assign static based on login details assign this value
    redirecturl += "&first_name=ehsan";

    //City i assign static based on login user detail you change this value
    redirecturl += "&city=rawalpindi";

    //State i assign static based on login user detail you change this value
    redirecturl += "&state=punjab";

    //Product Name
    redirecturl += "&item_name=" + packageName.Value.ToString();

    //Product Amount
    redirecturl += "&amount=" + tdPrice.InnerHtml;
    //Business contact id
    //redirecturl += "&business=nravindranmca@gmail.com";

    //Shipping charges if any
    redirecturl += "&shipping=5";

    //Handling charges if any
    redirecturl += "&handling=5";

    //Tax amount if any
    redirecturl += "&tax=5";

    //Add quatity i added one only statically 
    redirecturl += "&quantity=1";

    //Currency code 
    redirecturl += "&currency=USD";

    redirecturl += "&invoice=" + packageID.Value.ToString();

    redirecturl += "&custom=" + Session["userid"].ToString() + "," + packageID.Value.ToString() + "," + Session["purchaseType"].ToString();


    //Success return page url
    redirecturl += "&return=" + ConfigurationManager.AppSettings["SuccessURL"].ToString();

    //Failed return page url
    redirecturl += "&cancel_return=" + ConfigurationManager.AppSettings["FailedURL"].ToString();

    Response.Redirect(redirecturl);
}

这是 web.config 中的设置:

<add key="token" value="Jlt89XcvKKNRyLICXJCaWBlYoXxPify22EQlz3ZaColy51HdwJz05rILtd4" />
<add key="paypalemail" value="biznes_1357901741_biz@yahoo.com" />
<add key="PayPalSubmitUrl" value="https://www.sandbox.paypal.com/cgi-bin/webscr" />
<add key="FailedURL" value="http://localhost:4076/OpenLearningSolutions/Failed.aspx" />
<add key="SuccessURL" value="http://localhost:4076/OpenLearningSolutions/Success.aspx" />
