假设我正在做客户端的webservice请求。该请求由POST和json参数组成
在服务器中，Context.Request.RawUrl保留请求网址。但是json数据的请求是什么？
我需要此属性才能记录请求。
以下是http模块的代码：
public class RequestResponseLoggerModule : IHttpModule
{
//private static Logger logger = LogManager.GetCurrentClassLogger();
#region ResponseCaptureStream
private class ResponseCaptureStream : Stream
{
private readonly Stream _streamToCapture;
private readonly Encoding _responseEncoding;
public string StreamContent { get; private set; }
public ResponseCaptureStream(Stream streamToCapture, Encoding responseEncoding)
{
_responseEncoding = responseEncoding;
_streamToCapture = streamToCapture;
}
public override bool CanRead { get { return _streamToCapture.CanRead; } }
public override bool CanSeek { get { return _streamToCapture.CanSeek; } }
public override bool CanWrite { get { return _streamToCapture.CanWrite; } }
public override long Length { get { return _streamToCapture.Length; } }
public override long Position
{
get { return _streamToCapture.Position; }
set { _streamToCapture.Position = value; }
}
public override void Flush()
{
_streamToCapture.Flush();
}
public override int Read(byte[] buffer, int offset, int count)
{
return _streamToCapture.Read(buffer, offset, count);
}
public override long Seek(long offset, SeekOrigin origin)
{
return _streamToCapture.Seek(offset, origin);
}
public override void SetLength(long value)
{
_streamToCapture.SetLength(value);
}
public override void Write(byte[] buffer, int offset, int count)
{
StreamContent += _responseEncoding.GetString(buffer);
_streamToCapture.Write(buffer, offset, count);
}
public override void Close()
{
_streamToCapture.Close();
base.Close();
}
}

如果您在有效负载中使用json进行了POST，那么您需要阅读请求正文。您可以通过使用Request.InputStream来执行此操作，例如：
string json;
using (var reader = new StreamReader(Request.InputStream))
{
json = reader.ReadToEnd();
}
但是，您需要小心 - 因为使用正文可能意味着您的实际代码 无法 读取它。哪个会不好。
