我将POST数据发送到.NET简单服务器示例。在标题中我有一些其他细节，它们作为输入流打包到POST数据发送中。如何使用HandlePostRequest检索它们？我的源代码附在此处：

public void handlePOSTRequest() {

        Console.WriteLine("get post data start");
        int content_len = 0;
        MemoryStream ms = new MemoryStream();
        if (this.httpHeaders.ContainsKey("content-length")) {
             content_len = Convert.ToInt32(this.httpHeaders["content-length"]);
             if (content_len > MAX_POST_SIZE) {
                 throw new Exception(
                     String.Format("POST Content-Length({0}) too big for this simple server",
                       content_len));
             }
             byte[] buf = new byte[BUF_SIZE];

             int to_read = content_len;
             while (to_read > 0) {  
                 Console.WriteLine("starting Read, to_read={0}",to_read);
                 int numread = this.inputStream.Read(buf, 0, Math.Min(BUF_SIZE, to_read));

                 Console.WriteLine("read finished, numread={0}", numread);
                 if (numread == 0) {
                     if (to_read == 0) {
                         break;
                     } else {
                         throw new Exception("client disconnected during post");
                     }
                 }
                 to_read -= numread;
                 ms.Write(buf, 0, numread);
             }
             ms.Seek(0, SeekOrigin.Begin);
        }
        else
        {
            Console.WriteLine("Missing content length");
        }
        Console.WriteLine("get post data end");
        srv.handlePOSTRequest(this, new StreamReader(ms));

    }

我得到的一切都是content_length，但我需要从流中获取数据。该流由inputStream = new BufferedStream（socket.GetStream（））收集;在这个流中我有一个值“registration”=“123456789”，如何检索它？

你走了。

string data;
using (var streamReader = new StreamReader(Request.InputStream))
{
   data = streamReader.ReadToEnd();
}

虽然你需要的只是registration。

var registration = Request["registration"];

所有内容基本上都在Request个实例上，可以从Page，WebControl或HttpContext.Current.Request访问。在HttpHandler的情况下，HttpContext实例将为您传入。

public void ProcessRequest(HttpContext context)
{
    ...
}

.NET handlepostrequest - 检索数据
