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);
