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:https://3water.com/article/174034.htm
<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> </view> <text class="nlv-uid">U直播:{{item.uid}}</text> </view> <!-- //底部信息栏 --> <view class="nlv-footToolbar"> <!-- 送礼物提示 --> <view class="nlv-giftTipPanel"> ... </view> <!-- 滚动msg信息 --> <scroll-view class="nlv-rollMsgPanel" scroll-y show-scrollbar="false"> <block v-for="(msgitem, msgidx) in item.rollmsg" :key="msgidx"> <view class="nlv-msglist"><view class="msg_bg"><text class="msg_name">{{msgitem.uname}}</text> <text class="msg_text">{{msgitem.content}}</text></view></view> </block> </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;"></text></view> <view class="btn-toolitem btn-toolitem-cart" @tap="handleLiveGift"><text class="iconfont i-btntool"></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。?
最后,附上两个vue/react项目案例:
