paypal集成到自己购物网站，支付成功，notify_url调用正常，INVALID状态获取成功，但是return页面需要手工点击按钮才能返回自己网站，怎么自动跳回？

1)支付页面pay.aspx代码：
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write("<form action='https://www.paypal.com/cgi-bin/webscr' method='post' name='paypal'>");
Response.Write("<input name='cmd' value='_xclick' type='hidden'>");
Response.Write("<input type='hidden' name='notify_url' value='http://www.maiding.com/pp/notify.aspx/'>");
Response.Write("<input name='business' value='"+email.Text+"' type='hidden'>");
Response.Write("<input name='item_name' value='"+ordername.Text+"' type='hidden'>");
Response.Write("<input name='return' value='http://www.maiding.com/pp/pay_ok_return.aspx/' type='hidden'>");
Response.Write("<input type='hidden' name='cancel_return' value='http://www.maiding.com/pp/pay_fail_return.aspx/'>");
Response.Write("<input name='item_number' value='" + number.Text + "' type='hidden'>");
Response.Write("<input name='buyer_credit_promo_code' value='' type='hidden'>");
Response.Write("<input name='buyer_credit_product_category' value='' type='hidden'>");
Response.Write("<input name='buyer_credit_shipping_method' value='' type='hidden'>");
Response.Write("<input name='buyer_credit_user_address_change' value='' type='hidden'>");
Response.Write("<input name='no_shipping' value='0' type='hidden'>");
Response.Write("<input name='cn' value='Information' type='hidden'>");
Response.Write("<input name='no_note' value='0' type='hidden'>");
Response.Write("<input name='currency_code' value='USD' type='hidden'>");
Response.Write("<input name='bn' value='PP-BuyNowBF' type='hidden'>");
Response.Write("<input value='"+why.Text+"' name='on0'>");
Response.Write("<input value='Sender will be verified by telephone.' name='on1' type='hidden'>");
Response.Write("<input name='os0' type='hidden'>");
Response.Write("<input type='hidden' name='amount' value='"+money.Text+"'>");
Response.Write("<input name='os1' type='hidden'><br>");
Response.Write("<input src='https://www.paypal.com/en_US/i/btn/btn_buynow_LG.gif' name='submit' alt='Make payments with PayPal - it's fast, free and secure!' border='0' height='26' type='image' width='107'>");
Response.Write("<img alt='' src='../../../pixel.gif' border='0' height='1' width='1'>");
Response.Write("</form>");
}

2)notify.aspx.cs 代码：
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";
string strLive = "https://www.paypal.com/cgi-bin/webscr";
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);

//////////
StreamWriter w1 = new StreamWriter(Server.MapPath("recv1.txt"));
w1.Write(strRequest);
w1.Close();
//////////

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();

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
StreamWriter w2 = new StreamWriter(Server.MapPath("VERIFIED.txt"));
w2.Write("VERIFIED");
w2.Close();


}
else if (strResponse == "INVALID")
{
// log for manual investigation
StreamWriter w3 = new StreamWriter(Server.MapPath("INVALID.txt"));
w3.Write("INVALID");
w3.Close();
}
else
{
//log response/ipn data for manual investigation
}
}

3)pay_ok_return.aspx
<head runat="server">
<title>支付返回</title>
</head>
<body>
<form id="form1" runat="server">
<div>
支付成功---------------<br>
</div>
</form>
</body>
</html>


现在支付成功，notify_url调用正常，INVALID状态获取也成功，就是return页面需要手工点击按钮才能返回自己网站，怎么自动跳回？

做过的大侠告知一下，谢谢！！！

<meta http-equiv="refresh" content="2;url=yourweburl">
2秒钟转向你的网站

[tom_happy]

谢谢回复 但是这是paypal网站在支付完成后再跳转到指定的return页面，不是技术上怎么跳转的问题，而是怎么设置参数，paypal就会启动自动跳转，有经验的朋友帮帮忙。

[silkstockings]

顶 留个记号

[silkstockings]

我也在弄这个，LZ能不能发点资料到我邮箱[e-mail]

谢谢啦

[tom_happy]

呵呵 目前我了解的支付代码就这么多啊 都帖在上面了

不知道是不是其他方式才能实现自动跳回 这种方式本来就不支持？

[阿非]

没做过~　其实你把

<meta http-equiv="refresh" content="3;url=yourweburl">  

放在pay_ok_return.aspx 页　里　就应该是你想要的结果

[tom_happy]

顶~知道的告诉一下，谢谢啦

[tradesignal]

在你的paypal 帐户里设置autoreutn 打开

[fk1984316]

顶下！

[moontea]

就是return 这个参数未设置，跟技术没关系，另外在账户设置自动返回和加这个参数是一样的效果，设置其中一个就行了
我现在的问题是notify_url 没有返回，貌似神恶魔事情都没发生似的，郁闷！
我在本地调试的，是http:\\localhost开头的地址，难道他找不到？不应该呀，return都找到了，而且返回成功了呀？求高手解，我的是php的，notify文件用的是官网的事例文件，加了 写日志 ，但是日志里什么也木有，唉，PayPal折腾死人呀。
还想请教 并行付款和链式付款怎么弄呀，貌似这个很强大，官方好像也没有相应的 示例代码。

[ImFantasy]

搂在有答案了吗.?

在pp那边可以设置吗. 我现在也遇到这个问题.

[yanzhoupuzhang]

我也遇到了同样的问题！paypal真麻烦！
