socket.xu v1.0.0

socket.xu

封装一个socket插件玩

服务端

const ws = new WebSocketServer({port: 8888});

ws.defineUtil((connCaches) => {
    return {
        getAllUser() {
            return Object.values(connCaches).map(connObj => connObj.user);
        }
    }
})

ws.onconnection((socket, utils) => {
    // 登录事件
    socket.$on('login', (data) => {

        if (utils.checkLogin(data.user)) {
            socket.$emit('login result', {
                success: false,
                message: '用户名已存在，请更换'
            });
        } else {
            utils.login(socket, data.user, () => {
                socket.$emit('login result', {
                    success: true,
                    message: '登陆成功',
                    historyMessage: utils.getHistoryMessage(),
                });
                ws.$broadcast('online update', {
                    onlineUsers: utils.getAllUser()
                })
            })
        }
    });
    // 聊天事件
    socket.$on('message', (data) => {
        ws.$broadcast('new message', data);
    });
    // 注销事件
    ws.ondisconection((data) => {
        ws.$broadcast('user leave', {
            user: data.user
        });
        ws.$broadcast('online update', {
            onlineUsers: utils.getAllUser()
        });
    });
});

前端

var ws = new MyWebsocket(`ws://${location.hostname}:8888`);
ws.on('login result', (data) => {
    if (data.success) {
        this.currentUser = this.user;
        this.messageArr = data.historyMessage;
        this.$nextTick(()=> {
            this.setChatArea();
        });
    } else {
        this.user = '';
        alert(data.message);
    }
});

ws.on('new message', (data) => {
    this.messageArr.push({
        user: data.user,
        message: data.message
    });
    this.$nextTick(()=> {
        this.setChatArea();
    });
    
});
ws.on('online update', (data) => {
    this.onlineUsers = data.onlineUsers;
})


ws.$emit('message', {
    user: this.currentUser,
    message: chatMessage
});
