Bug Description and Steps to Reproduce

I configured Webhooks in the project, setting up a callback for message push before offline delivery (callbackBeforeOfflinePushCommand) and another for message push before online delivery (callbackBeforeOnlinePushCommand). When sending a message while the user is offline, I receive the callbackBeforeOfflinePushCommand notification. However, when the user is online, I’m not receiving the callbackBeforeOnlinePushCommand notification.

我尝试按照日志的打印的位置阅读了一下源码，我发现了以下一段代码:

func (c *ConsumerHandler) webhookBeforeOnlinePush(ctx context.Context, before *config.BeforeConfig, userIDs []string, msg *sdkws.MsgData) error {
	return webhook.WithCondition(ctx, before, func(ctx context.Context) error {
		if datautil.Contain(msg.SendID, userIDs...) || msg.ContentType == constant.Typing {
			return nil
		}
		req := callbackstruct.CallbackBeforePushReq{
			UserStatusBatchCallbackReq: callbackstruct.UserStatusBatchCallbackReq{
				UserStatusBaseCallback: callbackstruct.UserStatusBaseCallback{
					CallbackCommand: callbackstruct.CallbackBeforeOnlinePushCommand,
					OperationID:     mcontext.GetOperationID(ctx),
					PlatformID:      int(msg.SenderPlatformID),
					Platform:        constant.PlatformIDToName(int(msg.SenderPlatformID)),
				},
				UserIDList: userIDs,
			},
			ClientMsgID: msg.ClientMsgID,
			SendID:      msg.SendID,
			GroupID:     msg.GroupID,
			ContentType: msg.ContentType,
			SessionType: msg.SessionType,
			AtUserIDs:   msg.AtUserIDList,
			Content:     GetContent(msg),
		}
		resp := &callbackstruct.CallbackBeforePushResp{}
		if err := c.webhookClient.SyncPost(ctx, req.GetCallbackCommand(), req, resp, before); err != nil {
			return err
		}
		return nil
	})
}

问题很可能出现在这个判断上：

if datautil.Contain(msg.SendID, userIDs...) || msg.ContentType == constant.Typing {
			return nil
		}

日志中，msg.SendID 的值为 sendID：4514183745，userIDs的值为："userIDs" : [ 6346834060" , "4514183745"]，这里判断然后return 返回了，没有继续下面的回调的逻辑了。

我继续向上追查，看到有下面一个方法：

func (c *ConsumerHandler) handleMs2PsChat(ctx context.Context, msg []byte) {
	msgFromMQ := pbpush.PushMsgReq{}
	if err := proto.Unmarshal(msg, &msgFromMQ); err != nil {
		log.ZError(ctx, "push Unmarshal msg err", err, "msg", string(msg))
		return
	}

	sec := msgFromMQ.MsgData.SendTime / 1000
	nowSec := timeutil.GetCurrentTimestampBySecond()

	if nowSec-sec > 10 {
		prommetrics.MsgLoneTimePushCounter.Inc()
		log.ZWarn(ctx, "it’s been a while since the message was sent", nil, "msg", msgFromMQ.String(), "sec", sec, "nowSec", nowSec, "nowSec-sec", nowSec-sec)
	}
	var err error

	switch msgFromMQ.MsgData.SessionType {
	case constant.ReadGroupChatType:
		err = c.Push2Group(ctx, msgFromMQ.MsgData.GroupID, msgFromMQ.MsgData)
	default:
		var pushUserIDList []string
		isSenderSync := datautil.GetSwitchFromOptions(msgFromMQ.MsgData.Options, constant.IsSenderSync)
		if !isSenderSync || msgFromMQ.MsgData.SendID == msgFromMQ.MsgData.RecvID {
			pushUserIDList = append(pushUserIDList, msgFromMQ.MsgData.RecvID)
		} else {
			pushUserIDList = append(pushUserIDList, msgFromMQ.MsgData.RecvID, msgFromMQ.MsgData.SendID)
		}
		err = c.Push2User(ctx, pushUserIDList, msgFromMQ.MsgData)
	}
	if err != nil {
		log.ZWarn(ctx, "push failed", err, "msg", msgFromMQ.String())
	}
}

pushUserIDList 这里应该是把 RecvID 和 SendID 都往数组里面塞了。

我不太清楚这里面的逻辑，离线推送里面的代码并没有这个判断。
if datautil.Contain(msg.SendID, userIDs...) || msg.ContentType == constant.Typing {
return nil
}
