一、項目簡介
uni-liveShow是一個基于vue+uni-app技術開發的集小視頻/IM聊天/直播等功能于一體的微直播項目。界面仿制抖音|火山小視頻/陌陌直播,支持編譯到多端(H5、小程序、App端) 且兼容效果一致。
二、效果預覽
在H5、小程序、App端測試效果如下:(后續大圖均為APP端)
三、使用技術
◆ uniapp計算設備頂部狀態欄高度
/** * @desc uniapp主頁面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>
◆ 項目中頂部透明導航欄設置
頂部導航欄采用的是自定義模式,可設置透明背景(如:個人主頁/朋友圈動態) 具體可參看這篇文章:https://www.jb51.net/article/174034.htm
<header-bar :isBack="true" title=" " :bgColor="{background: 'transparent'}" transparent> <text slot="back" class="uni_btnIco iconfont icon-guanbi" ></text> <text slot="iconfont" class="uni_btnIco iconfont icon-dots mr_5" ></text> </header-bar>
◆ uniapp仿抖音小視頻效果
項目中小視頻界面功能效果類似抖音/火山小視頻,使用swiper組件實現上下滑動切換視頻播放。
<swiper :indicator-dots="false" :duration="200" :vertical="true" :current="videoIndex" @change="handleSlider" > <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> <!-- 中間播放按鈕 --> <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 ? '已關注' : '關注'}}</text> </view> <view class="item reply" @tap="handleVideoComment"><text class="iconfont icon-pinglun mr_5"></text> 寫評論...</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>
視頻滑動切換 播放、暫停 及單擊/雙擊判斷,商品及評論展示
<script> // 引入商品廣告、評論 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, //當前視頻是否播放中 clickNum: 0, //記錄點擊次數 } }, 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.$refs['myVideo' + i][0]) this.videoContextList.push(uni.createVideoContext('myVideo' + i, this)); } setTimeout(() => { this.play(this.videoIndex) }, 200) }, // 滑動切換 handleSlider(e) { let curIndex = e.detail.current if(this.videoIndex >= 0){ this.videoContextList[this.videoIndex].pause() this.videoContextList[this.videoIndex].seek(0) this.isPlay = false } if(curIndex === this.videoIndex + 1) { this.videoContextList[this.videoIndex + 1].play() this.isPlay = true }else if(curIndex === this.videoIndex - 1) { this.videoContextList[this.videoIndex - 1].play() this.isPlay = true } this.videoIndex = curIndex }, // 播放 play(index) { this.videoContextList[index].play() this.isPlay = true }, // 暫停 pause(index) { this.videoContextList[index].pause() this.isPlay = false }, // 點擊視頻事件 handleClicked(index) { if(timer){ clearTimeout(timer) } this.clickNum++ timer = setTimeout(() => { if(this.clickNum >= 2){ console.log('雙擊視頻') }else{ console.log('單擊視頻') if(this.isPlay){ this.pause(index) }else{ this.play(index) } } this.clickNum = 0 }, 300) }, // 喜歡 handleIsLike(index){ let vlist = this.vlist vlist[index].islike =! vlist[index].islike this.vlist = vlist }, // 顯示評論 handleVideoComment() { this.$refs.videoComment.show() }, // 顯示購物車 handleVideoCart(index) { this.$refs.videoCart.show(index) }, } } </script>
在項目開發過程中,遇到了視頻video層級高不能覆蓋的問題,使用nvue頁面就可以解決view覆蓋在video之上。.nvue
(native vue的縮寫)

◆ uniapp聊天頁面實現
項目中的聊天頁面,功能效果這里就不詳細介紹了,可參看這篇:uni-app聊天室|vue+uniapp仿微信聊天實例
◆ 直播頁面live.nvue
為避免video不能覆蓋問題,直播頁面采用的是nvue編寫,開發過程也遇到了一些坑,尤其是css,全部是flex布局,而且不能多級嵌套,有些css屬性不支持。
<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"> <!-- //直播區 --> <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" :> </video> <!-- //頂部 --> <view class="nlv_topbar" :> ... </view> <!-- //排名信息 --> <view class="nlv-rankbox" :> <view class="nlv-rkls"> <text class="rkitem">總排名{{item.allRank}}</text> <text v-if="item.hourRank" class="rkitem">小時榜第{{item.hourRank}}名</text> </view> <text class="nlv-uid">U直播:{{item.uid}}</text> </view> <!-- //底部信息欄 --> <view class="nlv-footToolbar"> <!-- 送禮物提示 --> <view class="nlv-giftTipPanel"> ... </view> <!-- 滾動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">說點什么...</text></view> <view class="nlv_btntool"> ... <view v-if="item.cart" class="btn-toolitem" @tap="handleLiveCart(index)"><text class="iconfont i-btntool" ></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> <!-- 商品廣告、滾動消息、禮物 --> <live-cart ref="liveCart" :vlist="vlist" /> <roll-msg ref="rollMsg" :vlist="vlist" /> <live-gift ref="liveGift" /> </div> </template>
另外引入阿里字體圖標也需注意:通過weex方式引入
beforeCreate() { // 引入iconfont字體 // #ifdef APP-PLUS const domModule = weex.requireModule('dom') domModule.addRule('fontFace', { fontFamily: "nvueIcon", 'src': "url('../../../static/fonts/iconfont.ttf')" }); // #endif },
至于視頻滑動切換和上面小視頻操作差不多,就不貼碼了。到這里,uni-liveShow項目基本介紹完了,希望對大家有些許幫助。💪
最后,附上兩個vue/react項目案例:

angular+ng-router手機端聊天IM實戰開發https://www.jb51.net/article/71356.htm
