贝宝ASP.NET C#获取引用者 [英] ASP.NET C# Get referer from Paypal
问题描述
我有一个很大的麻烦。我做了一个电子商务网站的许多个月前,现在我想做的事情,一个用户买了之后,贝宝重定向一个网站,确认买了一个电子邮件用户。
I have a big trouble. I've done an e-commerce site many month ago, now i wanna do that after an user has bought, paypal redirect the user in a website that confirm the bought with an e-mail.
显然,返回的页面有refererpage的控制,因为它不能发送确认邮件到所有写网页的地址,但该命令:
Obviously, the return page has a control of refererpage, because it can't send a confirmation mail to all that write the page address, but the command:
Request.ServerVariables["HTTP_REFERER"]
不行的,因为贝宝是HTTPS网页。所以,我怎么能解决呢?
Doesn't work, because paypal is an https webpage. So, how i can solve it?
在谢谢!
推荐答案
您好,你可以试试下面code此:
hi you can try below code for this:
首先设置notify_url在您的网站
First set the "notify_url" in your website
<input type="hidden" name="notify_url" value="http://www.your-website-url.com/notifypaypal.aspx" />
之后,创建notifypaypal.aspx页。
after that create notifypaypal.aspx Page.
notifypaypal.aspx:这里不需要任何code ..
notifypaypal.aspx : here not required any code ..
notifypaypal.aspx.cs:
notifypaypal.aspx.cs :
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Web.UI.HtmlControls;

using System.Net;

public partial class notifypaypal : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//Post back to either sandbox or live
// string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";//For localhost
string strLive = "https://www.paypal.com/cgi-bin/webscr";//For live server
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strLive);
//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);
string ipnPost = strRequest;
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//for proxy
//WebProxy proxy = new WebProxy(new Uri("http://url:port#"));
//req.Proxy = proxy;
//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();
// logging ipn messages... be sure that you give write permission to process executing this code
string logPathDir = ResolveUrl("Messages");
string logPath = string.Format("{0}\\{1}.txt",Server.MapPath(logPathDir), DateTime.Now.Ticks);
File.WriteAllText(logPath, ipnPost);
if (strResponse == "VERIFIED")
{
#region [Update Order Status]
string txn_id = HttpContext.Current.Request["txn_id"]; //txn_id= Unique transaction number.
string payment_status = HttpContext.Current.Request["payment_status"]; //payment_status=Payment state(Completed,Pending,Failed,Denied,Refunded)
string pending_reason = HttpContext.Current.Request["pending_reason"]; //pending_reason=Reason of payment delay(echeck,multi_currency,intl,verify,...)

if (HttpContext.Current.Request["payment_status"].ToString() == "Completed")
{
try
{
//update in database that particular "item_number"(Order number) is successfully Completed
}
catch
{
}
}
else

#endregion
}
