Weiterleiten HTTP-Anforderung an einen anderen Server

Question

Ich habe den folgenden Code, der Nachrichten empfängt Webhook:

// Read posted data 
string requestBody; 
using (var reader = new StreamReader(HttpContext.Current.Request.InputStream)) 
{ 
    requestBody = reader.ReadToEnd(); 
} 
requestBody.Log(); 

// Attempt to forward request 
context.CopyTo(Settings.Payments.Paypal.ScirraPaypalIPNEndpoint); 

requestBody enthält Daten, die protokolliert. Ich versuche dann die Anforderung an eine andere URL weiterleiten:

public static void CopyTo(this HttpContext source, string url) 
    { 
     var destination = (HttpWebRequest) WebRequest.Create(url); 

     var request = source.Request; 
     destination.Method = request.HttpMethod; 

     // Copy unrestricted headers 
     foreach (var headerKey in request.Headers.AllKeys) 
     { 
      if (WebHeaderCollection.IsRestricted(headerKey)) continue; 
      destination.Headers[headerKey] = request.Headers[headerKey]; 
     } 

     // Copy restricted headers 
     if (request.AcceptTypes != null && request.AcceptTypes.Any()) 
     { 
      destination.Accept = string.Join(",", request.AcceptTypes); 
     } 

     destination.ContentType = request.ContentType; 
     destination.Referer = request.UrlReferrer?.AbsoluteUri ?? string.Empty; 
     destination.UserAgent = request.UserAgent; 

     // Copy content (if content body is allowed) 
     if (request.HttpMethod != "GET" 
      && request.HttpMethod != "HEAD" 
      && request.ContentLength > 0) 
     { 
      using (var destinationStream = destination.GetRequestStream()) 
      { 
       request.InputStream.Position = 0; 
       request.InputStream.CopyTo(destinationStream); 
       destinationStream.Close(); 
      } 
     } 

     if (!Settings.Deployment.IsLive) 
     { 
      ServicePointManager.ServerCertificateValidationCallback = 
       (sender, certificate, chain, sslPolicyErrors) => true; 
     } 

     using (var response = destination.GetResponse() as HttpWebResponse) 
     { 
      if (response == null) throw new Exception("Failed to post to " + url); 
     } 
    } 

Der Handler, der diese weitergeleitet Anforderung empfängt den Code:

public void ProcessRequest(HttpContext context) 
{ 
    string requestBody; 
    using (var reader = new StreamReader(HttpContext.Current.Request.InputStream)) 
    { 
     requestBody = reader.ReadToEnd(); 
    } 
    requestBody.Log(); 
} 

jedoch auf dem Handler weitergeleitet, requestBody ist immer leer! Was mache ich hier falsch?

Answer 1

Beide Server sind in Cluffern, gehostet von einem zum anderen bekomme ich einen CF 1000 IP-Fehler.

Die Lösung besteht darin, Zielserver-IP-Adresse in anfordernde Server-Hosts-Datei hinzuzufügen.
