Uni-liveshow直播室是一个基于vue+Nvue+uniapp技术开发的集仿制抖音小视频/App聊天/直播功能混合项目。可实现类似抖音上下滑动切换视频播放，支持编译到多端。

效果展示：

技术栈：

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

公共组件及样式引入：

 /**
  * @desc 	uni-app主入口页面
  * @about 	Q：282310962  wx：xy190310
  */

import Vue from 'vue'
import App from './App'

// ***引入css
import './static/fonts/iconfont.css'
import './assets/css/reset.css'
import './assets/css/layout.css'

// ***引入状态管理
import store from './store'
Vue.prototype.$store = store

// ***引入公共组件
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)

// ***引入自定义弹窗组件uniPop
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()

获取顶部导航栏状态条高度，这里是为了自定义导航栏适配到不同的平台

<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>

uniapp仿抖音实现

uniapp+swiper+nvue技术实现仿抖音界面上下滑动切换视频效果，并且有点赞、评论及商品等功能，可以单击、双击判断。

<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>

小视频数据是通过模拟mock实现的

                    }else{
                        console.log('单击视频')
                        if(this.isPlay){
                            this.pause(index)

                    }
                    this.clickNum = 0
                }, 300)
            },
            
            
            ...
        }
    }
</script>

另外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
},

到这里大体就介绍差不多了，后续会继续更新一些项目实例。💪💪
