如果是字符串like不区分大小写的话，设置表中的该字符串类型未不区分大小写就可以了

discount_info_list = DiscountInfoModel.query.filter(or_(
    and_(DiscountInfoModel.discount_expiry_start_time <= today,
         DiscountInfoModel.discount_expiry_end_time >= today,
         DiscountInfoModel.discount_time_type == 0,
         "JSON_CONTAINS(shop_id->'$', '{}')".format(shop_info.get('shop_id'))),
    and_(DiscountInfoModel.discount_expiry_start_time <= today1,
         DiscountInfoModel.discount_expiry_end_time >= today1,
         DiscountInfoModel.discount_time_type == 1,
         "JSON_CONTAINS(shop_id->'$', '{}')".format(shop_info.get('shop_id')))
         )).all()

filter(DiscountInfoModel.shop_id.contains(shop_id))
