好啦~功能差不多就这些啦，这次添加了进出群提醒，主题颜色更换还有布局的一些调整。废话不多说啦，接下来该介绍介绍核心部分，以免被各位小哥哥，小姐姐打。

前端聊天代码

const infoObj = {
        status: \'userstate\',
        nickname: this.getUserinfo.nickname,
        roomId: this.roomId
    }
    this.socket.emit(\'join-room\', infoObj)
    this.socket.on(\'join-room\', (joinInfo) => {
        this.MsgList.push(joinInfo)
        this.$nextTick(() => {
                this.msgDOM.scrollTop = this.msgDOM.scrollHeight
        })
    })
    // 聊天
    this.socket.on(\'chat-msg\', (msg) => {
        console.log(msg)
        this.MsgList.push(msg)
        this.$nextTick(() => {
            this.msgDOM.scrollTop = this.msgDOM.scrollHeight
        })
    })
    // 离开房间
    this.socket.on(\'leave-room\', (leaveInfo) => {
        this.MsgList.push(leaveInfo)
        this.$nextTick(() => {
            this.msgDOM.scrollTop = this.msgDOM.scrollHeight
        })
    })

后端聊天代码

io.on(\'connection\', (socket) => {
  // 进入房间
  socket.on(\'join-room\', (info) => {
    // 添加到房间
    socket.join(info.roomId)
    const joinInfo = {
      status: info.status,
      text: info.nickname + \'加入了群聊\'
    }
    socket.to(info.roomId).broadcast.emit(\'join-room\', joinInfo)
  })
  // 群聊天
  socket.on(\'chat-msg\', (msg) => {
    saveChatMsg(msg, () => {
      io.to(msg.roomId).emit(\'chat-msg\', msg)
      // 分割聊天消息，判断是否与机器人聊天
      const msgArr = msg.text.split(\' \')
      const robotParam = {
        userId: msg.userId,
        roomId: msg.roomId || null,
        timeStamp: msg.timeStamp + 1 || null,
        text: msgArr[1]
      }
      if (msgArr[0] === \'@小美\') {
        getRobotMsg(robotParam, (robotmsg) => {
          saveChatMsg(robotmsg)
          io.to(msg.roomId).emit(\'chat-msg\', robotmsg)
        })
      }
    })
  })
  // 机器人聊天
  socket.on(\'robot-msg\', (msg) => {
    const robotParam = {
      userId: msg.userId,
      timeStamp: msg.timeStamp,
      text: msg.text
    }
    getRobotMsg(robotParam, (robotmsg) => {
      socket.emit(\'robot-msg\', robotmsg)
    })
  })
  // 离开房间
  socket.on(\'leave-room\', (info) => {
    socket.leave(info.roomId)
    const leaveInfo = {
      status: info.status,
      text: info.nickname + \'离开了群聊\'
    }
    socket.to(info.roomId).broadcast.emit(\'leave-room\', leaveInfo)
  })
})
