基于vue+uniapp直播项目|uni-app仿抖音/陌陌直播室

vue

 一、项目简介

uni-liveShow是一个基于vue+uni-app技术开发的集小视频/IM聊天/直播等功能于一体的微直播项目。界面仿制抖音|火山小视频/陌陌直播,支持编译到多端(H5、小程序、App端) 且兼容效果一致。

二、效果预览

在H5、小程序、App端测试效果如下:(后续大图均为APP端)

三、使用技术

  • 编码器+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封装自定义弹出窗)
  • 测试环境:H5端 + 小程序 + App端

◆ uniapp计算设备顶部状态栏高度

 /**

* @desc uniapp主页面App.vue

* @about Q:282310962 wx:xy190310

*/

<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>

◆ 项目中顶部透明导航栏设置

顶部导航栏采用的是自定义模式,可设置透明背景(如:个人主页/朋友圈动态) 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

<header-bar :isBack="true" title=" " :bgColor="{background: \'transparent\'}" transparent>

<text slot="back" class="uni_btnIco iconfont icon-guanbi" style="font-size: 25px;"></text>

<text slot="iconfont" class="uni_btnIco iconfont icon-dots mr_5" style="font-size: 25px;"></text>

</header-bar>

◆ uniapp仿抖音小视频效果

项目中小视频界面功能效果类似抖音/火山小视频,使用swiper组件实现上下滑动切换视频播放。

<swiper :indicator-dots="false" :duration="200" :vertical="true" :current="videoIndex" @change="handleSlider" style="height: 100%;">

<block v-for="(item,index) in vlist" :key="index">

<swiper-item>

<view class="uni_vdplayer">

<video :id="\'myVideo\' + index" :ref="\'myVideo\' + index" class="player-video" :src="item.src"

:controls="false" :loop="true" :show-center-play-btn="false" objectFit="fill">

</video>

<!-- 中间播放按钮 -->

<view class="vd-cover flexbox" @click="handleClicked(index)"><text v-if="!isPlay" class="iconfont icon-bofang"></text></view>

<!-- 底部信息 -->

<view class="vd-footToolbar flexbox flex_alignb">

<view class="vd-info flex1">

<view class="item at">

<view class="kw" v-for="(kwItem,kwIndex) in item.keyword" :key="kwIndex"><text class="bold fs_18 mr_5">#</text> {{kwItem}}</view>

</view>

<view class="item subtext">{{item.subtitle}}</view>

<view class="item uinfo flexbox flex_alignc">

<image class="avator" :src="item.avator" mode="aspectFill" /><text class="name">{{item.author}}</text> <text class="btn-attention bg_linear1" :class="item.attention ? \'on\' : \'\'" @tap="handleAttention(index)">{{item.attention ? \'已关注\' : \'关注\'}}</text>

</view>

<view class="item reply" @tap="handleVideoComment"><text class="iconfont icon-pinglun mr_5"></text> 写评论...</view>

</view>

<view class="vd-sidebar">

<view v-if="item.cart" class="ls cart flexbox bg_linear3" @tap="handleVideoCart(index)"><text class="iconfont icon-cart"></text></view>

<view class="ls" @tap="handleIsLike(index)"><text class="iconfont icon-like" :class="item.islike ? \'like\' : \'\'"></text><text class="num">{{ item.likeNum+(item.islike ? 1: 0) }}</text></view>

<view class="ls" @tap="handleVideoComment"><text class="iconfont icon-liuyan"></text><text class="num">{{item.replyNum}}</text></view>

<view class="ls"><text class="iconfont icon-share"></text><text class="num">{{item.shareNum}}</text></view>

</view>

</view>

</view>

</swiper-item>

</block>

</swiper>

视频滑动切换 播放、暂停 及单击/双击判断,商品及评论展示

<script>

// 引入商品广告、评论

import videoCart from \'@/components/cp-video/cart.vue\'

import videoComment from \'@/components/cp-video/comment\'

let timer = null

export default {

data() {

return {

videoIndex: 0,

vlist: videoJson,

isPlay: true, //当前视频是否播放中

clickNum: 0, //记录点击次数

}

},

components: {

videoCart, videoComment

},

onLoad(option) {

this.videoIndex = parseInt(option.index)

},

onReady() {

this.init()

},

methods: {

init() {

this.videoContextList = []

for(var i = 0; i < this.vlist.length; i++) {

// this.videoContextList.push(this.$refs[\'myVideo\' + i][0])

this.videoContextList.push(uni.createVideoContext(\'myVideo\' + i, this));

}

setTimeout(() => {

this.play(this.videoIndex)

}, 200)

},

// 滑动切换

handleSlider(e) {

let curIndex = e.detail.current

if(this.videoIndex >= 0){

this.videoContextList[this.videoIndex].pause()

this.videoContextList[this.videoIndex].seek(0)

this.isPlay = false

}

if(curIndex === this.videoIndex + 1) {

this.videoContextList[this.videoIndex + 1].play()

this.isPlay = true

}else if(curIndex === this.videoIndex - 1) {

this.videoContextList[this.videoIndex - 1].play()

this.isPlay = true

}

this.videoIndex = curIndex

},

// 播放

play(index) {

this.videoContextList[index].play()

this.isPlay = true

},

// 暂停

pause(index) {

this.videoContextList[index].pause()

this.isPlay = false

},

// 点击视频事件

handleClicked(index) {

if(timer){

clearTimeout(timer)

}

this.clickNum++

timer = setTimeout(() => {

if(this.clickNum >= 2){

console.log(\'双击视频\')

}else{

console.log(\'单击视频\')

if(this.isPlay){

this.pause(index)

}else{

this.play(index)

}

}

this.clickNum = 0

}, 300)

},

// 喜欢

handleIsLike(index){

let vlist = this.vlist

vlist[index].islike =! vlist[index].islike

this.vlist = vlist

},

// 显示评论

handleVideoComment() {

this.$refs.videoComment.show()

},

// 显示购物车

handleVideoCart(index) {

this.$refs.videoCart.show(index)

},

}

}

</script>

在项目开发过程中,遇到了视频video层级高不能覆盖的问题,使用nvue页面就可以解决view覆盖在video之上。.nvue (native vue的缩写)

更多关于nvue页面开发,可以参看:uniapp开发nvue页面

◆ uniapp聊天页面实现

项目中的聊天页面,功能效果这里就不详细介绍了,可参看这篇:uni-app聊天室|vue+uniapp仿微信聊天实例

◆ 直播页面live.nvue

为避免video不能覆盖问题,直播页面采用的是nvue编写,开发过程也遇到了一些坑,尤其是css,全部是flex布局,而且不能多级嵌套,有些css属性不支持。

<template>

<div class="nlv__container">

<view class="nlv_main">

<swiper class="nlv-swiper" :indicator-dots="false" :vertical="false" :current="videoIndex" @change="handleSlider">

<swiper-item v-for="(item, index) in vlist" :key="index">

<!-- //直播区 -->

<view class="nlv-playerbox">

<video :id="\'myVideo\' + index" :ref="\'myVideo\' + index" class="player-video" :src="item.src" :autoplay="index == videoIndex"

:controls="false" :loop="true" :show-center-play-btn="false" objectFit="fill" :style="{height: winHeight, width: winWidth}">

</video>

<!-- //顶部 -->

<view class="nlv_topbar" :style="{ height: headerBarH, \'padding-top\': statusBarH }">

...

</view>

<!-- //排名信息 -->

<view class="nlv-rankbox" :style="{top: headerBarH}">

<view class="nlv-rkls">

<text class="rkitem">总排名{{item.allRank}}</text>

<text v-if="item.hourRank" class="rkitem">小时榜第{{item.hourRank}}名</text>

<!-- 滚动msg信息 -->

<scroll-view class="nlv-rollMsgPanel" scroll-y show-scrollbar="false">

</scroll-view>

<view class="nlv-infobox">

<view class="nlv_reply" @tap="handleRollMsg(index)"><text class="nlv_reply_text">说点什么...</text></view>

<view class="nlv_btntool">

<view v-if="item.cart" class="btn-toolitem" @tap="handleLiveCart(index)"><text class="iconfont i-btntool" style="color: #ff4e0e;font-size: 20px;">&#xe61e;</text></view>

<view class="btn-toolitem btn-toolitem-cart" @tap="handleLiveGift"><text class="iconfont i-btntool">&#xe600;</text></view>

...

</view>

</view>

</view>

</view>

</swiper-item>

</swiper>

</view>

<!-- 商品广告、滚动消息、礼物 -->

<live-cart ref="liveCart" :vlist="vlist" />

<roll-msg ref="rollMsg" :vlist="vlist" />

<live-gift ref="liveGift" />

</div>

</template>

另外引入阿里字体图标也需注意:通过weex方式引入

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

},

至于视频滑动切换和上面小视频操作差不多,就不贴码了。 到这里,uni-liveShow项目基本介绍完了,希望对大家有些许帮助。
