uniapp-tlive 是基于 uni-app + uview-ui 开发的一款多平台短视频/直播/聊天实例。
使用技术
- 编码器/技术：HbuilderX3.1.21+Uniapp+Nvue+Vuex+Uapopup
- UI组件库：uView-ui / uni-ui
- 矢量图标库：iconfont字体图标
- 弹窗组件：UApopup 基于uni-app封装跨端弹窗组件
- 自定义导航条+底部菜单栏
- 编译支持：H5+小程序+APP端
HbuilderX3.1.21 编辑器开发，小视频及直播使用了nvue解决video层级问题，自定义 ua-navbar ua-tabbar ua-popup 组件全面支持Nvue页面。搭配 uview-ui 和 uni-ui 组件库。可编译至h5+小程序+APP端。
项目目录结构
App.vue全局获取并设置状态栏高度。
<script>
export default {
globalData: {
// 全局设置状态栏和导航栏高度
statusBarH: 0,
customBarH: 0,
},
onLaunch: function() {
console.log('App Launch')
let token = uni.getStorageSync('token')
if(!token) {
uni.navigateTo({
url: '/pages/auth/login'
})
}
uni.getSystemInfo({
success: (e) => {
// 获取手机状态栏高度
let statusBar = e.statusBarHeight
let customBar
// #ifndef MP
customBar = 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-ALIPAY
customBar = statusBar + e.titleBarHeight
// #endif
// 兼容nvue写法（H5/小程序/APP/APP-Nvue）
this.globalData.statusBarH = statusBar
this.globalData.customBarH = customBar
}
})
},
onShow: function() {
console.log('App Show')
},
onHide: function() {
console.log('App Hide')
}
}
</script>
<style>
/*每个页面公共css */
/* #ifndef APP-NVUE */
@import './static/fonts/iconfont.css';
/* #endif */
</style>
<style lang="scss">
@import './style/reset.scss';
@import './style/layout.scss';
@import "uview-ui/index.scss";
</style>
main.js公共配置
import Vue from 'vue'
import App from './App'
import uView from 'uview-ui'
Vue.use(uView)
// 引入状态管理
import Store from './store'
Vue.prototype.$store = Store
const app = new Vue({
...App
})
app.$mount()
uniapp自定义uaNavbar、uaTabbar、uaPopup组件。
目前组件已经上传到uniapp插件市场，有需要的可以拿走使用。
uni-app全端自定义导航条+tabbar组件
uni-app全端自定义多功能弹窗组件
<ua-popup v-model="isVisibleConfirm" shadeClose="false" title="标题" xclose z-index="1001"
content="<div style='color:#ff557f;padding:20px 40px;'>预测未来的最好办法是自己亲手创造未来！</div>"
:btns="[
{text: '取消', click: handleCancel},
{text: '确定', style: 'color:#00aa00;', click: handleOk},
]"
/>
还支持如下函数方法来调用组件。
<script>
export default {
methods: {
handleOk() {
let $ua = this.$refs.uapopup
$ua.open({
content: '人生漫漫，且行且珍惜',
customStyle: {'background-color': 'rgba(170, 0, 127, 0.6)', 'color': '#fff'},
time: 3,
onClose() {
$ua.open({
type: 'android',
content: '<div style="color:#aa007f">一切都将一去杳然，任何人都无法将其捕获。</div>',
customStyle: {'width': '210px'},
btns: [
{
text: '关闭',
click() {
$ua.close()
}
},
{
text: '确定',
style: 'color:#00aa00;',
click() {
// ...
}
}
]
})
}
})
}
}
}
</script>
uniapp开发短视频+直播
项目中的短视频及直播页面均是采用全屏悬浮透明式效果。使用的是nvue来开发，其中uaPopup弹窗组件已经支持nvue页面。
<view v-if="currentTab == 2" class="ua__tabcnt-recommend">
<swiper class="ua__vdplayer-swiper flex1" :current="currentVideo" vertical @change="handleSwipeVertical">
<swiper-item v-for="(item, index) in videoList" :key="index">
<!-- 视频模块 -->
<view class="ua__vdplayer-video flex1">
<video class="vdplayer" :id="'vdplayer' + index" :ref="'vdplayer' + index"
:src="item.src"
:controls="false" :loop="true" :show-center-play-btn="false" object-fit="fill"
:autoplay="index == currentVideo"
@play="isPlaying=true" @timeupdate="handleTimeUpdate"
:style="{'width': winWidth, 'height': winHeight}"
>
</video>
<view class="ua__vdplayer-playwrap" @click="handleVideoClicked"><view v-if="!isPlaying" class="ua__vdplayer-playbtn"><text class="iconfont">{{`\ue607`}}</text></view></view>
</view>
<!-- 信息模块 -->
<view class="ua__vdplayer-info flexbox flex-col">
<view class="flexbox flex-row flex-alignb">
<!-- //左侧信息 -->
<view class="vdinfo__left flex1">
<view class="ltitem uavatar flexbox flex-row">
<navigator url="#" class="flexbox flex-alignc flex-row"><image class="uimg" :src="item.avatar" /><text class="uname">{{item.author}}</text></navigator>
<view class="flexbox btn" :class="{'actived': item.isFollow}" @click="handleFollow(index)"><text class="btn-text">{{item.isFollow ? '已关注' : '关注'}}</text></view>
</view>
<view v-if="item.topic" class="ltitem flexbox flex-row">
<view class="kw" v-for="(kw, index2) in item.topic" :key="index2"><text class="lbl">#{{kw}}</text></view>
</view>
<view class="ltitem"><text class="desc">{{item.desc}}</text></view>
</view>
<!-- //右侧按钮 -->
<view class="vdinfo__right flexbox flex-col">
<view class="rtitem ball" v-if="item.goods&&item.goods.length > 0" @click="handleShowGoodsPopup(item.goods)"><text class="icon iconfont">{{`\ue734`}}</text></view>

<view class="rtitem" @click="showReplyPopup = true"><text class="icon iconfont">{{`\ue632`}}</text><text class="num">{{item.replyNum}}</text></view>
<view class="rtitem" @click="showSharePopup = true"><text class="icon iconfont">{{`\ue63b`}}</text><text class="num">{{item.shareNum}}</text></view>
</view>
</view>
</view>
</swiper-item>
</swiper>
<!-- 底部播放进度条 -->
<view class="ua__vdplayer-progress"><view class="bar" :style="{'width': progressBar+'px'}"></view></view>
</view>
小视频页面底部还有一条细细的播放进度条。
