PayPal IPN https 更改 2016

PayPal IPN https changes 2016

今天从 PayPal 收到信息：

IPN 验证回传到 HTTPS

If you are using PayPal’s Instant Payment Notification (IPN) service, you will >need to ensure that HTTPS is used when posting the message back to PayPal for >verification. After Sept 30, 2016 HTTP postbacks will no longer be supported.

我正在使用 IPN 并且实时站点正在运行，但是我们使用沙盒的 DEV IPN 侦听器位于：https://www.sandbox.paypal.com/cgi-bin/webscr 已损坏。

我很困惑我需要做些什么来修复它。我添加了这段代码，监听器页面再次加载而没有错误。

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls
| SecurityProtocolType.Tls11
| SecurityProtocolType.Tls12
| SecurityProtocolType.Ssl3;

ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

但是当我尝试测试交易时，侦听器永远不会从 PayPal 收到任何东西。这是因为监听器的服务器现在必须是"https"吗？
PP 沙盒现在是否拒绝通知非 SSL 地址？

我的 c# 代码最初来自一个 PayPal 示例，但它不再在他们的网站上。

var useSandbox = Convert.ToBoolean(ConfigurationManager.AppSettings["UsePayPalSandboxYn"]);
var server = useSandbox ?"https://www.sandbox.paypal.com/cgi-bin/webscr" :"https://www.paypal.com/cgi-bin/webscr";

var req = (HttpWebRequest)WebRequest.Create(server);

// set values for the request back
req.Method ="POST";
req.ContentType ="application/x-www-form-urlencoded";

//added today
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls
| SecurityProtocolType.Tls11
| SecurityProtocolType.Tls12
| SecurityProtocolType.Ssl3;

ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength);
var strRequest = Encoding.ASCII.GetString(param);
strRequest +="&cmd=_notify-validate";
req.ContentLength = strRequest.Length;

// send the request to PayPal and get the response
var streamOut = new StreamWriter(req.GetRequestStream(), Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
var streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();

switch (strResponse)
{
case"VERIFIED":
{

我使用静态 IP 地址和设置为 Web 服务器的家庭路由器进行调试。如果我必须设置 ssl，那就更难了。

谁能指出我正确的方向？

您唯一需要做的就是确保您将验证 POST 发送回 PayPal 到 https:// 而不是 http://。您不必在您的站点上安装 SSL 来运行您的 IPN 侦听器。

我只是想分享我正在运行的代码...希望它可以帮助您对您的代码进行一些改进：

using (var reader = new StreamReader(request.GetResponse().GetResponseStream()))

if (verificationResponse.Equals("VERIFIED"))

//Make the validations here
}
}
