fix(transport): fix request body not send again when not authorized

Under normal circumstances, the body of req will be read to EOF when the first request is made. If the first request is due to the permission reason and there is no request to complete, it needs to re-request after obtaining the token. But at this time req's body has reached EOF and may even be closed, so when resending the request, you need to reset the body so that the next request can re-read the body.
