uni-vue3-wchat:基于uni-app+vue3+pinia2高仿微信app聊天模板。
原创基于最新跨端技术
uni-app+vue3.x+pinia2+vite4+uv-ui
构建三端仿微信app界面聊天实例。实现编辑框多行消息/emoj混合、长按触摸式仿微信语音面板、图片/视频预览、红包/朋友圈等功能。支持编译到H5+小程序端+App端。
整个项目采用vue3 setup语法编码,支持编译到h5+小程序端+APP端。
使用技术
- 编辑器:HbuilderX 4.0.8
- 框架技术:Uniapp+Vue3+Pinia2+Vite4.x
- 组件库:uni-ui+uv-ui
- 弹窗组件:uv3-popup(uniapp+vue3多端自定义弹框组件)
- 导航栏+菜单栏:uv3-navbar+uv3-tabbar组件
- 本地缓存:pinia-plugin-unistorage
- 编译支持:H5+小程序+APP端
uniapp+vue3实现类似微信朋友圈功能。
项目结构
入口main.js配置
/*** 入口文件 main.js
*/import { createSSRApp } from 'vue'
import App from './App'// 引入pinia状态管理
import pinia from '@/pinia'export function createApp() {const app = createSSRApp(App)app.use(pinia)return {app,pinia}
}
App.vue配置
采用 vue3 setup
语法开发。
<script setup>import { provide } from 'vue'import { onLaunch, onShow, onHide, onPageNotFound } from '@dcloudio/uni-app'onLaunch(() => {console.log('App Launch')uni.hideTabBar()loadSystemInfo()})onShow(() => {console.log('App Show')})onHide(() => {console.log('App Hide')})onPageNotFound((e) => {console.warn('Route Error:', `${e.path}`)})// 获取系统设备信息const loadSystemInfo = () => {uni.getSystemInfo({success: (e) => {// 获取手机状态栏高度let statusBar = e.statusBarHeightlet customBar// #ifndef MPcustomBar = statusBar + (e.platform == 'android' ? 50 : 45)// #endif// #ifdef MP-WEIXIN// 获取胶囊按钮的布局位置信息let menu = wx.getMenuButtonBoundingClientRect()// 导航栏高度 = 胶囊下距离 + 胶囊上距离 - 状态栏高度customBar = menu.bottom + menu.top - statusBar// #endif// #ifdef MP-ALIPAYcustomBar = statusBar + e.titleBarHeight// #endif// 由于globalData在vue3 setup存在兼容性问题,改为provide/inject替代方案provide('globalData', {statusBarH: statusBar,customBarH: customBar,screenWidth: e.screenWidth,screenHeight: e.screenHeight,platform: e.platform})}})}
</script><style>/* #ifndef APP-NVUE */@import 'static/fonts/iconfont.css';/* #endif */
</style>
<style lang="scss">@import 'styles/reset.scss';@import 'styles/layout.scss';
</style>
uniapp+vue3自定义navbar+tabbar组件
<uv3-navbar :back="true" title="标题内容" bgcolor="#07c160" color="#fff" fixed zIndex="1010" /><uv3-navbar custom bgcolor="linear-gradient(to right, #07c160, #0000ff)" color="#fff" center transparent zIndex="2024"><template #back><uni-icons type="close" /></template><template #backText><text>首页</text></template><template #title><image src="/static/logo.jpg" style="height:20px;width:20px;" /> Admin</template><template #right><view class="ml-20" @click="handleAdd"><text class="iconfont icon-tianjia"></text></view><view class="ml-20"><text class="iconfont icon-msg"></text></view></template>
</uv3-navbar>
公共布局模板
整体项目结构采用顶部导航区域+主体内容区+底部区域。
<!-- 公共布局模板 --><!-- #ifdef MP-WEIXIN -->
<script>export default {/*** 解决小程序class、id透传问题* manifest.json中配置mergeVirtualHostAttributes: true, 在微信小程序平台不生效,组件外部传入的class没有挂到组件根节点上,在组件中增加options: { virtualHost: true }* https://github.com/dcloudio/uni-ui/issues/753*/options: { virtualHost: true }}
</script>
<!-- #endif --><script setup>const props = defineProps({// 是否显示自定义tabbarshowTabBar: { type: [Boolean, String], default: false },})
</script><template><view class="uv3__container flexbox flex-col flex1"><!-- 顶部插槽 --><slot name="header" /><!-- 内容区 --><view class="uv3__scrollview flex1"><slot /></view><!-- 底部插槽 --><slot name="footer" /><!-- tabbar栏 --><uv3-tabbar v-if="showTabBar" hideTabBar fixed /></view>
</template>
uni-app+vue3微信九宫格图像组
<script setup>import { onMounted, ref, computed, watch, getCurrentInstance } from 'vue'const props = defineProps({// 图像组avatar: { type: Array, default: null },})const instance = getCurrentInstance()const uuid = computed(() => Math.floor(Math.random() * 10000))const avatarPainterId = ref('canvasid' + uuid.value)const createAvatar = () => {const ctx = uni.createCanvasContext(avatarPainterId.value, instance)// 计算图像在画布上的坐标const avatarSize = 12const gap = 2for(let i = 0, len = props.avatar.length; i < len; i++) {const row = Math.floor(i / 3)const col = i % 3const x = col * (avatarSize + gap)const y = row * (avatarSize + gap)ctx.drawImage(props.avatar[i], x, y, avatarSize, avatarSize)}ctx.draw(false, () => {// 输出临时图片/* uni.canvasToTempFilePath({canvasId: avatarPainterId.value,success: (res) => {console.log(res.tempFilePath)}}) */})}onMounted(() => {createAvatar()})watch(() => props.avatar, () => {createAvatar()})

## emit
open 打开弹出层时触发(@open="xxx")
close 关闭弹出层时触发(@close="xxx")
uv3-popup支持函数式+组件式两种调用方式。
