Paypal IPN模拟器始终返回INVALID,尽管回发正确
我们正在升级我们的IPN以使用TLS,并在使用IPN模拟器时不断回复INVALID
当请求进入侦听器时,它会被记录。 在数据返回到paypal之前,会记录URL和数据。 此信息如下。
数据似乎没有任何问题。 我甚至使用diffmerge来确定除了cmd = _notify-validate&之外没有任何差异
只是IPN模拟器永远不会返回有效吗?
请求之前的URL是:
https://www.sandbox.paypal.com/cgi-bin/webscr
发布的数据是

供参考,代码是:
// This was legacy code I was trying in case there were formatting problems. The code "cmd=_notify-validate&" + _request.Form; does some URL encoding which I thought might be causing problems. Either way, we still get INVALID string s = "cmd=_notify-validate"; foreach (string paramName in _request.Form) { string paramValue = LicServiceTools.Encode(_request.Form[paramName]); //s = s + string.Format("&{0}={1}", paramName, paramValue); s = s + string.Format("&{0}={1}", paramName, _request.Form[paramName]); } string address = "https://www.paypal.com/cgi-bin/webscr"; if (this.useSandBox) { address = "https://www.sandbox.paypal.com/cgi-bin/webscr"; } System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(address); req.ProtocolVersion = HttpVersion.Version11; //Set values for the request back req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; // ALSO DOESNT WORK //string strRequest = "cmd=_notify-validate&" + _request.Form; //req.ContentLength = strRequest.Length; errorLogger.Info(s); errorLogger.Info(address); //Send the request to PayPal and get the response StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII); streamOut.Write(s); streamOut.Close(); StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream()); string strResponse = streamIn.ReadToEnd(); streamIn.Close(); // at this point, strResponse = INVALID
由于时区中的“+”,因此新的IPN模拟器payment_date变得混乱。 没有任何实时通知似乎列出这样的时区,所以以前的代码工作。
