C# Paypal IPN恢复为无效,不知道为什么
这是我的设置,我会尽量保持代码简短。这是一个ASP.NET MVC4应用程序 我在这里设置信息:C# Paypal IPN恢复为无效,不知道为什么,c#,asp.net-mvc,paypal,paypal-ipn,C#,Asp.net Mvc,Paypal,Paypal Ipn,这是我的设置,我会尽量保持代码简短。这是一个ASP.NET MVC4应用程序 我在这里设置信息: @Html.Hidden("cmd", Model.PayPal.Cmd) @Html.Hidden("business", Model.PayPal.Business) @Html.Hidden("return", Model.PayPal.Return) @Html.Hidden("cancel_return", Model.PayPal.CancelUrl) @Html.Hidden(

然后我有一个IPN控制器动作:
//Answer from PayPal
public ActionResult IPN()
{
var signInModel = Session["SignUp"] as SignUp;
//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(this.Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//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());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
if (strResponse == "VERIFIED")
{
//any param from form
var text = Request.Form["custom"];
ctx.SignIns.Add(signInModel);
ctx.SaveChanges();
//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
return View("RegistrationConfirmation", signInModel);
}
else if (strResponse == "INVALID")
{
//log for manual investigation
return View("SignUp", signInModel);
}
else
{
//log response/ipn data for manual investigation
}
//change view
return View("SignUp", signInModel);
}
让我恼火的是我被路由到paypal沙箱,我与测试用户一起登录,确认支付金额,然后单击返回站点。返回命中我的IPN操作,但我得到的响应是无效的。我是不是遗漏了一个变量?我对api还比较陌生。您试图在本地测试这个,但是paypal不知道localhost。您必须上传代码并使用实时url进行测试。如果您试图在本地进行测试,那么paypal不知道localhost。您必须上传代码并使用实时url测试它。另一个,cmd=\u notify-validate应该是需要发送的第一个参数值 根据官方文件 验证您的响应是否包含完全相同的IPN变量和值
order,前面带有cmd=\u notify-validate。另一个,cmd=\u notify-validate应该是需要发送的第一个参数值 根据官方文件 验证您的响应是否包含完全相同的IPN变量和值
order,前面带有cmd=\u notify-validate.所以我要传入cmd\u xclick-subscriptions,我是否同时传入这两个,如果是,我是否放入相同的字符串?像xclick-subscriptions和notify-validate一样,您的returnURL和notifyURL是相同的。因此,当用户登录到paypal时,他们返回到与IPN ActionResult相同的URL,而您试图发回不正确的响应。请始终注意,IPN就像一个webhook,它将在稍后发送,返回URL是即时的,它提供给您在您的应用程序中结帐购物车等。Indely有两个独立的returnURL和notifyURL端点,您在returnURL端点处得到的响应不需要发布回PayPal,这只需要用于可以是notifyURL端点的IPN。因此,我正在传递cmd xclick-subscriptions,我是否同时传递这两个端点,如果是,我是否输入相同的字符串?像xclick-subscriptions和notify-validate一样,您的returnURL和notifyURL是相同的。因此,当用户登录到paypal时,他们返回到与IPN ActionResult相同的URL,而您试图发回不正确的响应。请始终注意,IPN就像一个webhook,它将在稍后发送,返回URL是即时的,它提供给您在您的应用程序中结帐购物车等。Indely有两个独立的returnURL和notifyURL端点,您在returnURL端点处得到的响应无需发布回PayPal,这仅适用于可以是notifyURL端点的IPN。返回不应影响IPN操作。只有notifyUrl应该访问IPN。return命令应该指向什么?我要将逻辑保存到数据库的视图?是否只有在IPN成功返回时才会命中返回URL?返回URL在确认付款之前命中,因此无需验证-它始终无效。您可以返回“感谢订阅”页面,但在保存任何内容之前请等待通知。哦,好的,谢谢更有意义。你说保存前等待通知?我怎样才能在我的web应用程序中订阅该通知?PayPal应该向notifyUrl发送一个单独的请求,其中包含订阅注册和付款详细信息。因此,它需要是外部可见的,而不是本地主机。我会向控制器添加更多日志记录,以便您可以查看接收到的内容。返回不应影响IPN操作。只有notifyUrl应该访问IPN。return命令应该指向什么?我要将逻辑保存到数据库的视图?是否只有在IPN成功返回时才会命中返回URL?返回URL在确认付款之前命中,因此无需验证-它始终无效。您可以返回“感谢订阅”页面,但在保存任何内容之前请等待通知。哦,好的,谢谢更有意义。你说保存前等待通知?我怎样才能在我的web应用程序中订阅该通知?PayPal应该向notifyUrl发送一个单独的请求,其中包含订阅注册和付款详细信息。因此,它需要是外部可见的,而不是本地主机。我会向控制器添加更多日志记录,以便您可以查看接收到的内容。
