uni-app聊天室|vue+uniapp仿微信聊天实例|uniapp仿微信App界面
一、介绍
运用UniApp+Vue+Vuex+swiper+uniPop等技术开发的仿微信原生App聊天室|仿微信聊天界面实例项目uniapp-chatroom，实现了发送图文消息、表情(gif图)，图片预览、地图位置、长按菜单、红包/钱包、仿微信朋友圈等功能。
二、测试效果
H5 + 小程序 + App端测试效果如下，实测多端效果均为一致。(后续大图统一展示App端)
二、技术选型
- 编辑器：HBuilder X
- 技术框架：uni-app + vue
- 状态管理：Vuex
- iconfont图标：阿里字体图标库
- 自定义导航栏 + 底部Tabbar
- 弹窗组件：uniPop（基于uni-app封装模态弹窗）
- 测试环境：H5端 + 小程序 + App端（三端均兼容）
- 高德地图：vue-amap
◆ 顶部导航栏headerBar
顶部导航栏采用的是自定义模式，具体可参看这篇文章：uni-app自定义导航栏按钮|uniapp仿微信顶部导航条
在pages.json里面配置globalStyle，将navigationStyle设为custom时，原生顶部导航栏不显示，这时就能自定义导航栏
"globalStyle": {"navigationStyle": "custom"}
◆ 引入公共样式/组件及全局弹窗
import Vue from \'vue\'import App from \'./App\'
// >>>引入css
import \'./assets/fonts/iconfont.css\'
import \'./assets/css/reset.css\'
import \'./assets/css/layout.css\'
// >>>引入状态管理
import store from \'./store\'
Vue.prototype.$store = store
// >>>引入公共组件
import headerBar from \'./components/header/header.vue\'
import tabBar from \'./components/tabbar/tabbar.vue\'
import popupWindow from \'./components/popupWindow.vue\'
Vue.component(\'header-bar\', headerBar)
Vue.component(\'tab-bar\', tabBar)
Vue.component(\'popup-window\', popupWindow)
// >>>引入uniPop弹窗组件
import uniPop from \'./components/uniPop/uniPop.vue\'
Vue.component(\'uni-pop\', uniPop)
Vue.config.productionTip = false
App.mpType = \'app\'
const app = new Vue({
...App
})
app.$mount()
◆ Vuex + uniapp登录验证
import Vue from \'vue\'import Vuex from \'vuex\'
Vue.use(Vuex)
export default new Vuex.Store({
state: {
user: uni.getStorageSync(\'user\'),
token: uni.getStorageSync(\'token\'),
},
mutations: {
// 存储token
SET_TOKEN(state, data) {
state.token = data
uni.setStorageSync(\'token\', data)
},
// 存储用户名
SET_USER(state, data) {
state.user = data
uni.setStorageSync(\'user\', data)
},
...
},
})
<script>import { mapState, mapMutations } from \'vuex\'
import util from \'../../utils/util.js\'
export default {
data() {
return {
formObj: {},
}
},
computed: {
...mapState([\'user\', \'token\'])
},
mounted() {
// 判断是否有登录
if(this.user){
uni.redirectTo({url: \'/pages/index/index\'})
}
},
methods: {
// 提交表单
handleSubmit(e) {
...
}
}
}
</script>
◆ 仿微信朋友圈透明导航栏
通过onPageScroll函数实现自定义导航上下滑动自动调整导航栏的透明度，滑动到距离顶部200 效果如下图二
/*** @tpl 朋友圈模板
*/
<template>
<view class="flexbox flex_col">
<header-bar :isBack="true" title="朋友圈" :bgColor="{background: headerBarBackground}" transparent>
<text slot="back" class="uni_btnIco iconfont icon-arrL"></text>
<text slot="iconfont" class="uni_btnIco iconfont icon-publish mr_5" @tap="handlePublish"></text>
</header-bar>
<view class="uni__scrollview flex1">
<view class="uni-friendZone">
...
</view>
</view>
</view>
</template>
<script>
export default {
data() {
return {
headerBarBackground: \'transparent\'
}
},
onPageScroll : function(e) {
// console.log("滚动距离为：" + e.scrollTop);
this.headerBarBackground = \'rgba(65,168,99,\'+e.scrollTop / 200+\')\'
},
methods: {
...
}
}
</script>
<style scoped>
</style>
◆ uniapp实现聊天页面滚动至底部
在h5端将聊天页面滚动到底部很好实现，小程序中通过设置scroll-view属性scroll-into-view的值也能实现，可是在uni-app里面怎么将聊天信息滚动至底部呢？
uni-app通过判断聊天内容高度和scroll-view高度的大小设置滚动距离
<scroll-view id="scrollview" scroll-y="true" :scroll-top="scrollTop" style="height: 100%;"><view class="uni-chatMsgCnt" id="msglistview">
<view class="msgitem">xxx</view>
<view class="msgitem">xxx</view>
<view class="msgitem">xxx</view>
...
</view>
</scroll-view>
export default { data() {
return {
scrollTop: 0,
...
}
},
mounted() {
this.scrollToBottom()
},
updated() {
this.scrollToBottom()
},
methods: {
// 滚动至聊天底部
scrollToBottom(t) {
let that = this
let query = uni.createSelectorQuery()
query.select(\'#scrollview\').boundingClientRect()
query.select(\'#msglistview\').boundingClientRect()
query.exec((res) => {
// console.log(res)
if(res[1].height > res[0].height){
that.scrollTop = res[1].height - res[0].height
}
})
},
...
}
}
◆ uniapp聊天代码片段
<script>const emotionJson = require(\'./mock-emotion.js\')
const messageJson = require(\'./mock-chat.js\')
export default {
data() {
return {
scrollTop: 0,
showFootToolbar: false,
showEmotionChoose: false,
editorText: \'\',
editorLastCursor: null,
// 表情json
emotionList: emotionJson,
// 消息记录
messageList: messageJson,
// 预览图片临时数组
previewImgArray: [],
}
},
mounted() {
this.scrollToBottom()
},
updated() {
this.scrollToBottom()
},
methods: {
// 滚动至聊天底部
scrollToBottom(t) {
let that = this
let query = uni.createSelectorQuery()
query.select(\'#scrollview\').boundingClientRect()
query.select(\'#msglistview\').boundingClientRect()
query.exec((res) => {
// console.log(res)
if(res[1].height > res[0].height){
that.scrollTop = res[1].height - res[0].height
}
})
},
// 点击聊天消息区域
msgPanelTaped() {
if(!this.showFootToolbar) return
this.showFootToolbar = false
},
// 表情、选择区切换
swtEmotionChooseView(bool) {
this.showFootToolbar = true
this.showEmotionChoose = bool
},
...
// 点击表情
handleEmotionTaped(emoj) {
if(emoj == \'del\') return
// 在光标处插入表情
let startStr = this.editorText.substr(0, this.editorLastCursor)
let endStr = this.editorText.substr(this.editorLastCursor)
this.editorText = startStr + `${emoj}` + endStr
},
// >>> 【选择区功能模块】------------------------------------------
// 选择图片
handleLaunchImage() {
let that = this
let msglist = this.messageList
let len = msglist.length
// 消息队列
let data = {
id: `msg${++len}`,
msgtype: 5,
isme: true,
avator: \'/static/uimg/u__chat_img1.jpg\',
author: \'King\',
msg: \'\',
imgsrc: \'\',
videosrc: \'\'
}
uni.chooseImage({
count: 1,
sourceType: [\'album\'],
success: function(res){
// console.log(res)
// console.log(res.tempFilePaths)
data.imgsrc = res.tempFilePaths.toString()
msglist = msglist.concat(data)
that.messageList = msglist
}
})
},
...
// 位置
handleChooseLocation() {
let that = this
let msglist = this.messageList
let len = msglist.length

uni.chooseLocation({

console.log(res)

data.msg = {

}
msglist = msglist.concat(data)
that.messageList = msglist
