ASP.. NET c#从Paypal获得推荐
本文关键字:Paypal NET ASP | 更新日期: 2023-09-27 18:10:57
我遇到了一个大麻烦。几个月前我做了一个电子商务网站,现在我想在用户购买后,paypal将用户重定向到一个用电子邮件确认购买的网站。
显然,返回页有对refererpage的控制,因为它不能向所有写页地址的人发送确认邮件,但是命令:
Request.ServerVariables["HTTP_REFERER"]
不工作,因为paypal是一个https网页。那么,我该如何解决它呢?
谢谢你之前!
嗨,你可以试试下面的代码:
首先在你的网站设置"notify_url"
<input type="hidden" name="notify_url" value="http://www.your-website-url.com/notifypaypal.aspx" />
之后,创建notifypaypal。aspx页面。
notifypaypal。Aspx:这里不需要任何代码…
notifypaypal.aspx.cs:

//WebProxy proxy = new WebProxy(new Uri("http://url:port#"));
//req.Proxy = proxy;
//Send the request to PayPal and get the response
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
