示例1: CreateBufferedRequestContentAsync

        private static async Task<HttpContent> CreateBufferedRequestContentAsync(IOwinRequest owinRequest,
            CancellationToken cancellationToken)
        {
            // We need to replace the request body with a buffered stream so that other components can read the stream.
            // For this stream to be useful, it must NOT be diposed along with the request. Streams created by
            // StreamContent do get disposed along with the request, so use MemoryStream to buffer separately.
            MemoryStream buffer;
            int? contentLength = owinRequest.GetContentLength();

            if (!contentLength.HasValue)
            {
                buffer = new MemoryStream();
            }
            else
            {
                buffer = new MemoryStream(contentLength.Value);
            }

            cancellationToken.ThrowIfCancellationRequested();

            using (StreamContent copier = new StreamContent(owinRequest.Body))
            {
                await copier.CopyToAsync(buffer);
            }

            // Provide the non-disposing, buffered stream to later OWIN components (set to the stream's beginning).
            buffer.Position = 0;
            owinRequest.Body = buffer;

            // For MemoryStream, Length is guaranteed to be an int.
            return new ByteArrayContent(buffer.GetBuffer(), 0, (int)buffer.Length);
        }
