【中文标题】无法通过Paypal测试工具测试IPN（HTTP错误代码500）_Asp.net【英文标题】：IPN can't be tested through Paypal test tool (HTTP error code 500) _ Asp.net 【发布时间】：2012-10-04 18:33:28 【问题描述】：美好的一天 我一直在尝试为 PayPal 运行 IPN 处理程序；我已遵循所有可能的说明（我希望如此），但是在贝宝 IPN 测试工具上，我不断收到代码 500 的错误。 我使用的代码是 johnmendez00 作为开源提供的；该类是通过创建一个实例来调用的
PPIPN objPP = new PPIPN("TEST");
objPP.FromEmail = "email@yourdomain.com";
objPP.FromEmailPassword = "yourpassword";
objPP.SmtpHost = "yourSMTPHost";
objPP.SmtpPort = "SMTPHostPort";
objPP.ToEmail = "youremailatPayPal@domain.com";/
objPP.MakeHttpPost();
objPP.CheckStatus();

对这里可能出现的问题有什么想法吗？
【问题讨论】：
已经以某种方式解决了 ASP.NET 只有一个表单的问题，这可能已经存在？您在使用 PayPal 按钮小部件吗？ 是的，我正在使用 PayPal 按钮；我如何让它工作是通过在每个按钮上方添加和清空 标记，它可以正常工作。 唯一的问题是没有人知道它为什么会这样工作。希望请求代码会有所帮助.. 【参考方案1】：来自 PayPal 网站的按钮 HTML 嵌入在表单标签中。 ASP.NET 页面上只能有一个表单，而 ASP.NET 提供了它自己的表单。如果你有一个母版页，那么表单标签就在其中，当它们在运行时与母版合并时，它会应用于站点中的每个页面。
我在 Jeremy Schneider 的博客上找到了一个 elegant solution，它包含一个自定义 HtmlForm 类，可以打开和关闭表单标签呈现。该类称为 GhostForm，并具有一个属性 RenderFormTag。当 RenderFormTag 设置为 false 时，它不会呈现开始或结束标签，但会呈现所有内容。引用自定义 GhostForm 类，并在您放置按钮的表单的代码隐藏中，将以下内容放在 Page_Load 中以禁用母版页表单标记：
用法：
public partial class Products : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
GhostForm mainForm = new GhostForm();
mainForm.RenderFormTag = false;
.....
// Send your data to PayPal :-)
.....
重要提示：在发送此请求之前，请确保您已登录沙盒。
更新：观看这些教学视频：http://www.asp.net/mvc/videos/mvc-1/aspnet-mvc-storefront/aspnet-mvc-storefront-part-1-architectural-discussion-and-overview
和你一样，我使用了 John Mendez 的 IPN 代码。这是我从 PayPal 发送和接收的地方：
string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strLive);
//Set values for the request back to PayPal
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 += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//Send the request to PayPal
StreamWriter streamOut =
new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
// Get the response from PayPal
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
希望这会有所帮助。 500 个错误可以是任何东西...
【讨论】：
确实很有帮助；出于某种原因，我仍然看到错误；但我确实受益匪浅。既然您运行了 John 的代码，是否有可能创建一个关于如何部署它的指南？这将非常有用...谢谢您的麻烦... 我刚刚将 John 的代码合并到我的项目中的一个类中 - 它是我的 Web App DLL 的一部分。我在这里发布了一些关于 PayPal 的博客文章：codersbarn.com/?tag=/paypal 这个博客也帮助了我：west-wind.com/presentations/paypalintegration/… 我在答案中添加了视频链接。 我将您的答案标记为解决方案；我在您发送的视频中找到了我想要的内容....谢谢 谢谢 :-) 出于好奇，您对哪一部分有疑问？以上是关于无法通过Paypal测试工具测试IPN（HTTP错误代码500）_Asp.net的主要内容，如果未能解决你的问题，请参考以下文章
