通过下面的伪代码生成返回报文ens返回给微信小店，但是微信小店没有关联会员成功，没有收到“用户静默关联小店会员通知”。通过“获取小程序会员列表”接口查询结果，显示也没有会员。麻烦排查下为什么没有关联成功？为什么没有回调“channels_ec_vip_user_auto_add”类型的事件给业务系统？

pc = new WXBizMsgCrypt("微信小店的token", "微信小店秘钥", "微信小店appId");
String replyMsg = "{\"errcode\": 0,\"errmsg\": \"ok\",\"info\": {\"is_vip\": true,\"identity\": \"五折卡\", \"outer_userid\": \"EO122222\"}}";
String ens = pc.encryptMsgJson(replyMsg, Long.toString(System.currentTimeMillis()/1000), String.valueOf(new Random().nextInt(1000000000)));

返回给微信的报文如下：
