I checked a lot of documents and couldn"t find them, and some people in the community asked but no one answered.
at present, my practice is to get the users of the official account and then get the code, through open_id, but the speed is very slow because there is no batch interface, and there is also a lack of membership card data (it has been proved that it may be due to the reason that it is not associated with the official account).
do you have any good solutions? Thank you ~
