我一直收到INVALID回复。这是我的代码:
protected void Page_Load(object sender, EventArgs e)
{
ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
ServicePointManager.Expect100Continue = true;
mclog.Info("entered PayPalListener Page_Load");
//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";
mclog.Info(string.Format("strSandbox = [{0}]", strSandbox));
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;
mclog.Info(string.Format("strRequest = [{0}]", strRequest));
//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();
mclog.Info(string.Format("Response was [{0}]", strResponse));
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
}
我已经包含了日志输出,并且还引用了Sandbox页面上显示的结果:

我还在解码和编码中尝试过Encoding.UTF8,但是当在接收和发送中使用时这样做都会失败,但是在接收和接收时都没有。发送UTF8时,握手完全失败。
答案 0 :(得分:2)
这个问题是由" +" IPN模拟器在payment_date字段中插入的符号。就我而言 2016年7月23日星期六08:52:03 GMT + 0930(AUS中央标准时间) 取出" +"解决了这个问题。
基本上,加分被剥离了:
string payment_date = Form.Request [" payment_date"];
2016-07-22 16:09:33:751 W15 INFO MyPayPal.PayPal.PayPalListener.Page_Load.0 payment_date = [Sat Jul 23 2016 08:38:14 GMT 0930(AUS中央标准时间)]
将参数返回到没有加号的PayPal足以使请求无效。
我会在这里和其他地方搜索,试图找出一种允许这种方式的方法,但加上(并且可能)减去似乎以MSDN或RFC DateTime格式为特色,以便我可以检查它&# 39;原始存在是一种担忧。
