从C#中的context.httprequest读取原始数据

Question

我已经多次看过这个话题,但没有一个解决方案对我有帮助,我不知道为什么没有任何作用.

我有一个C#web部分,我只是想读取http post请求的数据内容.在请求中有一些xml,但是当我尝试在Web部分中读取它时,这不会显示出来.它只给我标题数据和一些服务器变量.

我正在尝试阅读的请求是通过Chrome的Simple Rest扩展提交的.当我用fiddler监视时,我可以看到请求,当我点击TextView时,我可以看到所有的XML都没有问题.那么为什么它不显示在服务器上？

我尝试使用Context.Request.SaveAs(),但似乎只给我标题数据.我也尝试循环遍历Context.Request.Params并打印每个参数,但它们都不包含xml.

最后,我尝试使用读取请求的内容

Context.Request.ContentEncoding                     
       .GetString(Context.Request.BinaryRead(Context.Request.TotalBytes))

并且

string strmContents = "";
using (StreamReader reader = new StreamReader(Context.Request.InputStream))
{
    while (reader.Peek() >= 0)
    {
       strmContents += reader.ReadLine();
    }
}

但这两种方法都会导致空字符串.

让我感到困惑(并加剧)的是,如果我查看Context.Request.ContentLength它,它与我的XML中的字符数相同!我知道内容已经过去,但我不知道如何访问它.

我觉得发布这个很糟糕,因为代码不是我的,但我找不到原帖.

这个扩展方法对我来说非常有用,你只需使用它:HttpContext.Current.Request.ToRaw();

using System.IO;
using System.Web;
using log4net;

namespace System.Web.ExtensionMethods
{
    /// <summary>
    /// Extension methods for HTTP Request.
    /// <remarks>
    /// See the HTTP 1.1 specification http://www.w3.org/Protocols/rfc2616/rfc2616.html
    /// for details of implementation decisions.
    /// </remarks>
    /// </summary>
    public static class HttpRequestExtensions
    {

    /// <summary>
    /// Dump the raw http request to a string. 
    /// </summary>
    /// <param name="request">The <see cref="HttpRequest"/> that should be dumped.               </param>
    /// <returns>The raw HTTP request.</returns>
    public static string ToRaw(this HttpRequest request)
    {
        StringWriter writer = new StringWriter();

        WriteStartLine(request, writer);
        WriteHeaders(request, writer);
        WriteBody(request, writer);

        return writer.ToString();
    }

    public static string GetBody(this HttpRequest request)
    {
        StringWriter writer = new StringWriter();
        WriteBody(request, writer);

        return writer.ToString();
     }

     private static void WriteStartLine(HttpRequest request, StringWriter writer)
     {
         const string SPACE = " ";

          writer.Write(request.HttpMethod);
          writer.Write(SPACE + request.Url);
          writer.WriteLine(SPACE + request.ServerVariables["SERVER_PROTOCOL"]);
     }


     private static void WriteHeaders(HttpRequest request, StringWriter writer)
     {
            foreach (string key in request.Headers.AllKeys)
            {
                   writer.WriteLine(string.Format("{0}: {1}", key, request.Headers[key]));
            }

            writer.WriteLine();
      }


      private static void WriteBody(HttpRequest request, StringWriter writer)
      {
           StreamReader reader = new StreamReader(request.InputStream);

            try
            {
                string body = reader.ReadToEnd();
                writer.WriteLine(body);
            }
            finally
            {
                reader.BaseStream.Position = 0;
            }
        }
}
}
