先看一下项目效果
这个是我运行的作者的项目的wetalk-server项目，他还有wetalk-client 项目
先放下作者的github项目地址：https://github.com/mangyui/weTalk
这是一个才华横溢的作者，而且才大三。羡慕作者的青春，也羡慕他们的努力，不需要预计的是作者的前途无量。
因为运行中有点问题，就给作者提了issue
（后记作者人很好，很快就解决了Bug,万分感谢）
先言归正传，看可以运行的wetalk-server项目吧
一般server中都会引入websocket
作者在服务端使用的是Node + WebSocket 搭配 Express
看package.json文件
{
"name": "wetalk-server",
"version": "1.0.0",
"description": "we talk server",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"main": "nodemon build/main.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"@types/express": "^4.16.1",
"express": "^4.17.0",
"typescript": "^3.4.5",
"ws": "^7.0.0"
},
"devDependencies": {
"@types/ws": "^6.0.1",
"nodemon": "^1.19.0"
}
}
入口文件main.ts
import express = require('express')
const app: express.Application = express();
app.use(express.static('public'));
const port:number = 9612
const WebSocket = require('ws')
app.get('/', function (req, res) {
res.send('Hello World!');
});
var server = app.listen(port, '0.0.0.0', () => {
console.log('Example app listening on port ' + port);
});
const wss = new WebSocket.Server({ server });
// Broadcast to all.
const broadcast = (data: string) => {
console.log('ccc', wss.clients.size)
var dataJson = JSON.parse(data)
dataJson.number = wss.clients.size
wss.clients.forEach((client: any) => {
if (client.readyState === WebSocket.OPEN) {
client.send(JSON.stringify(dataJson));
}
});
};
wss.on('connection', (ws: any) => {
console.log(new Date().toUTCString() + ' - connection established');
ws.on('message', (data: string) => {
broadcast(data);
});
ws.on('error', (error: any) => {
console.log(error);
});
wss.on('close', (mes: any) => {
console.log(mes);
console.log('closed');
});
});
wss.on('error', (err: any) => {
console.log('error');
console.log(err);
});
接下来我们来看客户端的项目
运行效果同服务器中的是一样的，作者是将前端项目打包之后放在后端public里面的。
先上代码
在main.js中会引入router以及对应的museui等框架
import Vue from 'vue'
import App from './App.vue'
import router from './router/'
import store from './store/'
import './plugins/museui.js'
import '@/styles/index.less'
import './guard.ts'
const Toast = require('muse-ui-toast')
Vue.config.productionTip = false
// Vue.use(Toast)
new Vue({
el: '#app',
router,
store,
render: h => h(App)
}).$mount('#app') // 与el: '#app'对应，手动挂载
guard.ts中进行了路由守卫的一些功能，能够判断当时对应的用户的信息
//guard.ts
import router from './router'
import store from './store'
import User from './model/user'
import Person from './assets/js/person'
let persons : Person[] = require('./assets/js/persons').persons //
// const whiteList = ['/login',
// '/'
// ] // 不重定向白名单
router.beforeEach((to, from, next) => {
console.log('....store.getters.user',store.getters.user)
console.log('....store.getters.user.id',store.getters.user.id)
if (!store.getters.user.id) {
console.log('id.....', store.getters.user)
var date = new Date(+new Date() + 8 * 3600 * 1000).toISOString().replace(/[T:-]/g, '').replace(/\.[\d]{3}Z/, '')
var index = Math.floor(Math.random() * persons.length)
var user = new User(date.substring(2) + index, persons[index].name, persons[index].avatar, '男')
store.commit('initUserInfo', user)
next()
// if (whiteList.indexOf(to.path) !== -1) {
// next()
// console.log('aaaaaaaa')
// } else {
// console.log('bnbbbb')
// next('/')
// }
} else {
console.log('cccc')
next()
}
})
接下来看router中的文件,router中进行懒加载，以及对应的跳转页面信息
//src\router\index.ts
import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/views/Home.vue'
Vue.use(Router)
export default new Router({
routes: [
{
path: '',
component: () => import('@/views/Home.vue'),
redirect: '/home/lobby'
},
{
path: '/home',
name: 'home',
component: () => import('@/views/Home.vue'),
children: [
{
path: 'lobby',
name: 'Lobby',
component: () => import('@/components/Lobby.vue')
},
{
path: 'usercenter',
name: 'UserCenter',
component: () => import('@/components/UserCenter.vue')
}
]
},
{
path: '/WorldRoom',
name: 'WorldRoom',
component: () => import('@/views/WorldRoom.vue')
},
{
path: '*',
redirect: '/'
}
]
})
在App.vue里面定义了页面渲染的入口
<template>
<div id="app">
<!-- <div id="nav">
<router-link to="/">Home</router-link> |
<router-link to="/about">About</router-link>
</div> -->
<router-view />
</div>
</template>
<style lang="less">
#app {
font-family: "Avenir", Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
}
#nav {
padding: 30px;
a {
font-weight: bold;
color: #2c3e50;
&.router-link-exact-active {
color: #42b983;
}
}
}
</style>
接下来我们看各个页面效果
这个是在home.vue
<template>
<div class="home">
<router-view />
<mu-bottom-nav :value.sync="tab" @change="changeTab">
<mu-bottom-nav-item value="labby" title="大厅" icon="home"></mu-bottom-nav-item>
<mu-bottom-nav-item value="usercenter" title="我" icon="account_circle"></mu-bottom-nav-item>
</mu-bottom-nav>
</div>
</template>
<script lang="ts">
import { Component, Vue } from 'vue-property-decorator'
@Component({
})
export default class Home extends Vue {
private tab: string = 'labby'
changeTab () {
if (this.tab === 'labby') {
this.$router.push('/home/lobby')
} else {
this.$router.push('/home/usercenter')
}
}
created () {
if (this.$route.name === 'UserCenter') {
this.tab = 'usercenter'
}
}
}
</script>
<style lang="less">
.about{
.mu-bottom-nav-shift-wrapper{
justify-content: space-around;
}
.mu-paper-round{
height: calc(100% - 56px);
}
}
</style>
页面一开始进来会渲染的是lobby组件，但是也会加载UserCenter组件里面的内容
这部分是lobby组件渲染的,也是纯的UI组件，不过有路由跳转的功能，可以跳到另一个页面
<template>
<div>
<mu-paper :z-depth="0" class="">
<mu-appbar :z-depth="0" color="lightBlue400">
<mu-button icon slot="left">

<mu-list-item-action>
<mu-icon value="speaker_notes_off"></mu-icon>
</mu-list-item-action>

<mu-list-item-action>
<mu-icon value="speaker_notes_off"></mu-icon>
</mu-list-item-action>
</mu-list-item>
</mu-list>
</mu-paper>
</div>
</template>
<script lang="ts">
import { Component, Vue } from 'vue-property-decorator'
@Component
export default class Lobby extends Vue {

</script>
<style lang="less" scoped>
.mu-list{
background: #fff;
box-shadow: 0 1px 1px rgba(0, 0, 0, 0.05);
}
</style>
这个就是跳转到的世界聊天室页面
这里使用的是WorldRoom组件
//src\views\WorldRoom.vue
<template>
<div class="talk-room">
<mu-paper :z-depth="0" class="demo-list-wrap">
<mu-appbar :z-depth="0" color="cyan">

p,.mu-input{

在model文件夹下，定义了字段的一些基本类型
//src\model\message.ts
import User from './user'
class Message {
public time: string
public content: string = ''
public type: number // 0 为系统消息(加入聊天室) -1（退出聊天室） 1为用户消息
public user: User | null
constructor (time: string, content: string, type: number, user: User | null) {
this.time = time
this.content = content
this.type = type
this.user = user
}
}
export default Message
//src\model\room.ts
class Room {
private id: number
public name: string = ''
private number: number
constructor (id: number, name: string, number: number) {
this.name = name
this.id = id
this.number = number
if (this.name === '') {
this.name = '第'+this.id+'号聊天室'
}
}
}
export default Room
//src\model\user.ts
class User {
public id: string // 当前以时间为id
public name: string = ''
public sex: string = ''
private avatar : string
constructor (id: string, name: string, avatar: string, sex: string) {
this.id = id
this.name = name
this.avatar = avatar
this.sex = sex
if (this.name === '') {
this.name = '游客'
}
}
getUserId (): string {
return this.id
}
}
export default User
在store中，我们定义的是数据的状态
usercenter对应的状态,里面还使用了localstorage存储数据
//user.ts
import User from '../model/user'
export default {
state: {
user: JSON.parse(localStorage.getItem('user') || '{}') || {}
},
mutations: {
updateUserAvatar (state: any, avatar: string) {
state.user.avatar = avatar
localStorage.setItem('user', JSON.stringify(state.user))
},
updateUserName (state: any, name: string) {
state.user.name = name
localStorage.setItem('user', JSON.stringify(state.user))
},
initUserInfo (state: any, user: User) {
state.user = user
localStorage.setItem('user', JSON.stringify(state.user))
},
logoutUser (state: any) {
state.user = {}
localStorage.setItem('user', JSON.stringify(state.user))
}
},
actions: {}
}
room.ts中的为更新room的数量名字以及初始化和关闭等方法
import Room from '../model/room'
export default {
state: {
isLiving: true,
room: {}
},
mutations: {
closeOpenRoom (state: any, living: boolean) {
state.isLiving = living
},
updateRoomNumber (state: any, number: number) {
state.room.number = number
},
updateRoomname (state: any, username: string) {
state.room.number = username
},
initRoomInfo (state: any, room: Room) {
state.room = room
}
},
actions: {}
}
message中为,可以添加message,也可以移除message
import Message from '../model/message'
export default {
state: {
msgList: JSON.parse(sessionStorage.getItem('msgList') || '[]') || []
},
mutations: {
// 添加数据方法
addMsg (state: any, msg: Message) {
// 数据列表中添加数据
state.msgList.push(msg)
sessionStorage.setItem('msgList', JSON.stringify(state.msgList))
},
// 移除数据
removeMsg (state: any, msg: Message) {
let index = '-1'
for (const key in state.msgList) {
if (state.msgList.hasOwnProperty(key)) {
if (state.msgList[key].time === msg.time && msg.user && state.msgList[key].user.id === msg.user.id) {
console.log('key', state.msgList[key])
index = key
}
}
}
// console.log('index', msg, new Message(state.msgList[3].time, state.msgList[3].content, state.msgList[3].type, state.msgList[3].user))
console.log('index', index)
if (index !== '-1') {
let time = new Date(+new Date() + 8 * 3600 * 1000).toISOString().replace(/T/g, ' ').replace(/\.[\d]{3}Z/, '')
let message = new Message(time, (msg.user ? msg.user.name : '用户') + ' 撤回了一条消息', 0, null)
state.msgList.splice(index, 1, message)
// state.msgList.push(msg)
sessionStorage.setItem('msgList', JSON.stringify(state.msgList))
}
}
