我在asp.net编写的IIS服务器中使用IPN Samulator,c#但我遇到错误" IPN未发送,并且握手未经验证。"。我的托管服务器使用普通的http而不支持ssl。我的测试网址为http://realestate.owncircles.com/ipn.aspx。
代码:
ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
// receive PayPal ipn data
// extract ipn data into a string
byte[] param = Request.BinaryRead(Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
// append PayPal verification code to end of string
strRequest += "&cmd=_notify-validate";
// create an HttpRequest channel to perform handshake with PayPal
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(System.Configuration.ConfigurationManager.AppSettings["paypalIPN"].ToString());
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = strRequest.Length;
// send data back to PayPal to request verification
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
// receive response from PayPal
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
// if PayPal response is successful / verified
if (strResponse.Equals("VERIFIED"))
{
}

用这个
替换你的代码//Post back to either sandbox or live
string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";
string strLive = "https://www.paypal.com/cgi-bin/webscr";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox);
//Set values for the request back
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] Param = Request.BinaryRead(HttpContext.Current.Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(Param);
strRequest = strRequest + "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//for proxy
//var proxy = New WebProxy(New System.Uri("http://url:port#"))
//req.Proxy = proxy
//Send the request to PayPal and get the response
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
if (strResponse == "VERIFIED")
{
//check the payment_status is Completed
//check that txn_id has not been previously processed
//check that receiver_email is your Primary PayPal email
//check that payment_amount/payment_currency are correct
//process payment
}
else if (strResponse == "INVALID")
{
//log for manual investigation
}
else
{
//Response wasn't VERIFIED or INVALID, log for manual investigation
}
}
