实际项目中遇到的问题

const data = await queryLiveMsgList({
          lastMsgId:
            this.liveMessage.length > 0 ? this.liveMessage[this.liveMessage.length - 1].id : 0,
          lastMsgTime:
            this.liveMessage.length > 0
              ? new Date(this.liveMessage[this.liveMessage.length - 1].createTime).getTime() / 1000
              : 0,
          order: 0,
          size: 10,
          stageId: this.stageId
        });

解决方法

    new Date(xxx.replace(/-/g,'/')).getTime()
