When I send Long string in FetchResponse
throw execption
Invalid URI: The Uri string is too long.
回答1:
AX, or any other OpenID extension, is not designed to carry large payloads. If you have an image or other large binary data to transmit, it's better to make the image accessible via a URL and then transmit the URL over AX.
