近期看到网上有一个APICloud的教程,蕴含AVM多端开发框架教程和APICloud的云数据开发,并用APICloud开发了一个短视频的多端利用。
本文节选了案例实战的局部,重点介绍几个性能的前端实现。
一、成果预览
首先咱们先来看一下实现成果
二、我的项目前端实现
本我的项目中前端采纳APICloud AVM多端开发技术进行开发,要点包含 swiper 轮播图、网络申请封装等。应用 APICloud 多端技术进行开发,实现一套代码多端运行,反对编译成 Android & iOS App 以及微信小程序。
1、APICloud应用步骤:
(1)下载 APICloud Studio 3 作为开发工具。下载地址:www.apicloud.com/studio3
(2)注册账号后在控制台创立app,控制台地址:www.apicloud.com/console
能够在控制台创立
也能够在APICloud Studio 3间接创立我的项目
2、编写首页轮播图
设置stml模板轮播内容
<swiper class="swiper" :circular="false" :vertical="true" @change="onchange"> <swiper-item class="swiper-item" v-for="item,index in videoList"> <video :src="item.src" :controls="false" :id="'video'+index" onclick="togglePause" onpause="onpause" onplay="onplay" onended="onended"></video> </swiper-item> </swiper>
编写script数据和办法
import '../../components/tabbar.stml'export default { name: "tpl", apiready() { api.setStatusBarStyle({ style: "light", color: "-" }); }, data() { return { isShow: "none", videoContext: null, current: 0, page: 1, videoList: [ { id: "000", nickname: "老陈打码", content: "新年快乐,万事如意!", like: "3.5w", share: "3821", collect: "2988", comment: "3475", isLike: false, pubtime: "2022-01-10 01:30", headimg: "https://a415432669.github.io/shortvideo/000.jpg", src: 'https://a415432669.github.io/shortvideo/000.mp4' }, { id: "001", nickname: "学习告诉", content: "高兴学习APICloud多端利用开发", like: "3.5w", share: "3821", collect: "2988", comment: "3475", isLike: false, pubtime: "2022-01-10 01:30", headimg: "https://a415432669.github.io/shortvideo/001.jpg", src: 'https://a415432669.github.io/shortvideo/001.mp4' }, ] }; }, methods: { handleClick(e) { api.toast({ msg: this.data.text, location: "middle" }); }, onchange(event) { // console.log(event.detail.current) this.current = event.detail.current; if (this.current === this.videoList.length - 1) { this.page++; api.ajax({ url: "https://a6197037785854-dev.apicloud-saas.com/api/videos/getVideoList?obj=" + JSON.stringify({ page: this.page, limit: 2 }) }, (ret, err) => { // console.log(ret) // this.videoList = this.videoList.concat(ret.data) ret.data.forEach(item => this.videoList.push(item)) if (ret.data.length == 0) { api.toast({ msg: '劳动一下,视频很快会更新!' }) } }) } this.videoContext && this.videoContext.pause() document.querySelector('#video' + this.current).$$getContext().then((context) => { this.videoContext = context; this.videoContext.play() }) }, togglePause() { this.videoContext.pause() }, togglePlay() { this.videoContext.play() }, onplay() { this.isShow = "none" }, onpause() { this.isShow = "flex" }, onended() { this.videoContext.play() }, likeFn() { this.videoList[this.current].isLike = !this.videoList[this.current].isLike; }, shareFn() { this.videoList[this.current].share++; } }, apiready() { document.querySelector('#video' + this.current).$$getContext().then((context) => { this.videoContext = context; this.videoContext.play() }) }};
轮播局部设计款式内容
.swiper { width: 100vw; height: 100vh;}.swiper-item video { width: 100vw; height: 100vh;}.playBtn { width: 40vw; height: 40vw; position: fixed; left: 50%; top: 50%; margin-left: -20vw; margin-top: -20vw; display: flex; justify-content: center; align-items: center; opacity: 0.7;}.playBtn image { width: 10vw; height: 10vw;}.rightBar { display: flex; flex-direction: column; position: fixed; right: 0; width: 20vw; bottom: 15vw; height: 80vw;}.right-item { width: 100%; height: 20vw; display: flex; justify-content: center; align-items: center; font-size: 3vw; color: #fff;}.right-item image { width: 8vw; height: 8vw;}.desc { width: 50vw; height: 20vw; color: #fff; display: flex; flex-direction: column; justify-content: flex-start; align-items: flex-start; position: fixed; left: 0; bottom: 18vw; padding: 4vw; text-align: left; overflow: hidden;}
最终成果
3、编写tabbar导航组件
<template> <view class="tabbar"> <view class="tab-item" :style="{color:active=='index'?'#fff':'#bbb'}" @click="goPage('index')">首页</view> <view class="tab-item" :style="{color:active=='friend'?'#fff':'#bbb'}" @click="goPage('friend')">敌人</view> <view class="tab-item" @click="goPage('addVideo')"> <image src="../../image/add.png" /> </view> <view class="tab-item" :style="{color:active=='message'?'#fff':'#bbb'}" @click="goPage('message')">音讯</view> <view class="tab-item" :style="{color:active=='me'?'#fff':'#bbb'}" @click="goPage('me')">我</view> </view></template><script>export default { name: 'tabbar', props: { active: String }, apiready() {//like created }, data() { return { } }, methods: { goPage(pagename) { let pagePath = { index: '../index/index', friend: "../friend/friend", message: '../message/message', me: '../me/me', addVideo: '../addVideo/addVideo', } wx.redirectTo({ url: pagePath[pagename] }) } }}</script><style>.tabbar { position: fixed; bottom: 0; left: 0; color: #fff; height: 15vw; width: 100vw; background: #000; display: flex; flex-direction: row;}.tabbar .tab-item { width: 20%; height: 15vw; display: flex; justify-content: center; align-items: center;}.tabbar .tab-item image { width: 8vw; height: 8vw;}</style>
成果如下
4、编写敌人页面
<template> <view class="page"> <view class="friends"> <view class="friend-item" v-for="(item,index) in videoList"> <view class="friend-header"> <image :src="item.headimg" /> <view class="msg"> <view class="username">{{item.nickname}}</view> <view class="time">{{item.pubtime}}</view> </view> </view> <view class="content"> {{item.content}} </view> <view class="video"> <video :src="item.src"></video> </view> <view class="iconlist"> <div class="icon-item"> <image src="../../image/heart_border.png" /> <text>{{item.like}}</text> </div> <div class="icon-item"> <image src="../../image/comment_border.png" /> <text>{{item.comment}}</text> </div> <div class="icon-item"> <image src="../../image/share_border.png" /> <text>{{item.share}}</text> </div> </view> </view> </view> <tabbar active="friend"></tabbar> </view></template><script>import "../../components/tabbar.stml"export default { name: 'friend', apiready() {//like created }, data() { return { videoList: [ { id: "000", nickname: "老陈打码", content: "新年快乐,万事如意!", like: "3.5w", share: "3821", collect: "2988", comment: "3475", isLike: false, pubtime: "2022-01-10 01:30", headimg: "https://a415432669.github.io/shortvideo/000.jpg", src: 'https://a415432669.github.io/shortvideo/000.mp4' }, { id: "001", nickname: "学习告诉", content: "高兴学习APICloud多端利用开发", like: "3.5w", share: "3821", collect: "2988", comment: "3475", isLike: false, pubtime: "2022-01-10 01:30", headimg: "https://a415432669.github.io/shortvideo/001.jpg", src: 'https://a415432669.github.io/shortvideo/001.mp4' }, { id: "002", nickname: "小清爽", content: "感激每一个咱们关上世界的人", like: "3.5w", share: "3821", collect: "2988", comment: "3475", isLike: false, pubtime: "2022-01-10 01:30", headimg: "https://a415432669.github.io/shortvideo/002.jpg", src: 'https://a415432669.github.io/shortvideo/002.mp4' }, { id: "003", nickname: "琦琦", content: "当你来到世界,他就领有了超能力!致平凡的父亲", like: "3.5w", share: "3821", collect: "2988", comment: "3475", isLike: false, pubtime: "2022-01-10 01:30", headimg: "https://a415432669.github.io/shortvideo/003.jpg", src: 'https://a415432669.github.io/shortvideo/003.mp4' }, { id: "004", nickname: "老陈打码", content: "虎年大吉,虎虎生财好运来!", like: "3.5w", share: "3821", collect: "2988", comment: "3475", isLike: false, pubtime: "2022-01-10 01:30", headimg: "https://a415432669.github.io/shortvideo/004.jpg", src: 'https://a415432669.github.io/shortvideo/004.mp4' }, ] } }, methods: { }}</script><style>.page { height: 100%;}.friends { display: flex; flex-direction: column;}.friend-item { display: flex; flex-direction: column; padding: 4vw;}.friend-item .friend-header { display: flex; flex-direction: row;}.friend-item .friend-header image { width: 10vw; height: 10vw; border-radius: 5vw; margin-right: 2vw;}.friend-item .friend-header .msg { display: flex; flex-direction: column;}.friend-item .friend-header .username { font-weight: 900; font-size: 4vw;}.friend-item .msg .time { font-weight: 900; font-size: 3vw;}.friend-item .content { padding: 3vw 0;}.video video { height: 80vw; width: 45vw;}.friend-item .iconlist { display: flex; flex-direction: row;}.iconlist .icon-item { display: flex; flex-direction: row; width: 20vw; height: 10vw; justify-content: center; align-items: center;}.iconlist .icon-item image { width: 6vw; height: 6vw; margin-right: 2vw;}</style>
页面成果如下
