一、介绍说明
U 直播 uniLiveShow 是一款基于 vue+Nvue+uni-app 技术开发的综合小视频 / 聊天室 / 直播等功能的聊天直播项目。界面高仿热门抖音 | 火山小视频 / 陌陌直播，可滑动切换视频播放，且支持编译到多端且兼容效果一致。
二、项目预览
在 H5、小程序、App 端及真机测试效果一致 如下：
三、编码实现：
- 编辑器 + 技术：HBuilderX + vue/NVue/uniapp/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（uni-app 封装自定义 Modal 弹窗）
- 测试环境：H5 端 / 小程序 /App 端 / 真机
顶部状态条高度获取
<script>
import Vue from 'vue'
export default {onLaunch: function() {// console.log('App Launch')
uni.getSystemInfo({success:function(e){
Vue.prototype.statusBar = e.statusBarHeight
// #ifndef MP
if(e.platform == 'android') {Vue.prototype.customBar = e.statusBarHeight + 50}else {Vue.prototype.customBar = e.statusBarHeight + 45}
// #endif
// #ifdef MP-WEIXIN
let custom = wx.getMenuButtonBoundingClientRect()
Vue.prototype.customBar = custom.bottom + custom.top - e.statusBarHeight
// #endif
// #ifdef MP-ALIPAY
Vue.prototype.customBar = e.statusBarHeight + e.titleBarHeight
// #endif
}
})
},
}
</script>引入公共组件及样式

import App from './App'

import './assets/css/layout.css'
// 状态管理
import store from './store'
Vue.prototype.$store = store
// 公共组件
import headerBar from './components/header/header.vue'
import tabBar from './components/tabbar/tabbar.vue'
import popupWindow from './components/popupWindow.vue'
Vue.component('header-bar', headerBar)
Vue.component('tab-bar', tabBar)
Vue.component('popup-window', popupWindow)
// 自定义弹窗组件
import uniPop from './components/uniPop/uniPop.vue'
Vue.component('uni-pop', uniPop)
Vue.config.productionTip = false
App.mpType = 'app'
const app = new Vue({...App})
app.$mount() 至于聊天页面功能效果这里就不讲述了。

</script> 在开发小视频页面过程中，遇到了视频 video 层级过高不能被其他组件覆盖，如是使用 nvue 页面就可以解决 view 覆盖在 video 之上。.nvue (native vue 的缩写)
且在 nvue 页面中使用 iconfont 图标库需注意引入方式
beforeCreate() {
// 引入 iconfont 字体
// #ifdef APP-PLUS
const domModule = weex.requireModule('dom')
domModule.addRule('fontFace', {
fontFamily: "nvueIcon",
'src': "url('../../../static/fonts/iconfont.ttf')"
});
// #endif
},至此 uni-app 开发直播聊天项目介绍到这里，后续继续为大家分享实战项目，希望能有一些许帮助！！
