こんにちは、PayPal の IPN Handler を実行しようとしています。考えられるすべての指示に従いましたが (願わくば)、paypal IPN テスト ツールでコード 500 のエラーが表示され続けます。使用したコードは、johnmendez00 によってオープンソースとして提供されたものです。クラスは、インスタンスを次のように作成することによって呼び出されます

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();

インスタンスのクラスは次のとおりです。

PayPal サイトのボタン HTML が form タグに埋め込まれています。ASP.NET ページには 1 つのフォームのみを含めることができ、ASP.NET は独自のフォームを提供します。マスター ページがある場合、フォーム タグはそこにあり、実行時にマスターとマージされるときに、サイト内のすべてのページに適用されます。

Jeremy Schneider のブログで、フォーム タグのレンダリングのオンとオフを切り替えることができるカスタム HtmlForm クラスで構成されるエレガントなソリューションを見つけました。このクラスは GhostForm と呼ばれ、プロパティ RenderFormTag を持っています。RenderFormTag が false に設定されている場合、開始タグまたは終了タグはレンダリングされませんが、すべてのコンテンツがレンダリングされます。カスタム GhostForm クラスを参照し、ボタンを配置するフォームのコード ビハインドで、Page_Load に次を配置して、マスター ページのフォーム タグを無効にします。

使用法：

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 :-)
     .....
 }

あなたと同じように、私は John Mendez の IPN コードを使用しました。PayPal から送受信する場所は次のとおりです。

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();

うまくいけば、これが役に立ちます。500個のエラーは何でもかまいません...
