如何在.NET中接收post數據（XML），如java servlet doPost

Question

我想接收HTTP POST數據（XML），其他webServer（Tomcat，shttpd）發佈的XML數據。

在Java上，我可以使用servlet doPost接收發布數據，我是C＃上的新手，我不知道如何在c＃上編寫它。

Answer 1

在.NET中，網絡數據通信由WCF覆蓋。

Windows通訊基礎

Windows通訊基礎（WCF）是Microsoft用於構建面向服務的應用程序的統一編程模型。它使開發人員能夠構建安全，可靠，事務處理的解決方案，跨平臺集成並與現有投資進行互操作。

有關使用Web服務的信息，請參閱Building Windows Communication Foundation Clients。

Answer 2

我寫了一個簡單的接收數據使用System.Net.HttpListener類，但是這隻接收一次並退出編程。

我該如何收回更多。

想想。

Answer 4

while(true) 
{ 
    listener.Start(); 
     Console.WriteLine("Listening..."); 
     // Note: The GetContext method blocks while waiting for a request. 
     HttpListenerContext context = listener.GetContext(); 

     HttpListenerRequest request = context.Request; 
     ShowRequestData(request); 


     // Obtain a response object. 
     HttpListenerResponse response = context.Response; 
     // Construct a response. 
     string responseString = "ok"; 
     byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString); 
     // Get a response stream and write the response to it. 
     response.ContentLength64 = buffer.Length; 
     System.IO.Stream output = response.OutputStream; 
     output.Write(buffer, 0, buffer.Length); 
     // You must close the output stream. 
     output.Close(); 

     listener.Stop();
