近期有开发者制作了一套APICloud的教程，包含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应用。
本文节选了案例实战的部分，重点介绍几个功能的前端实现。
一、效果预览
首先我们先来看一下实现效果
二、项目前端实现
本项目中前端采用APICloud AVM多端开发技术进行开发，要点包括 swiper 轮播图、网络请求封装等。使用 APICloud 多端技术进行开发，实现一套代码多端运行，支持编译成 Android & iOS App 以及微信小程序。
1、APICloud使用步骤：
（1）下载 APICloud Studio 3 作为开发工具。下载地址：/studio3
（2）注册账号后在控制台创建app，控制台地址：/console
可以在控制台创建
也可以在APICloud Studio 3直接创建项目
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="" :controls="false" : onclick="togglePause" onpause="onpause"
onplay="onplay" onended="onended"></video>
</swiper-item>
</swiper>

编写script数据和方法
import '../../components/'
export default {
name: "tpl",
apiready() {
({
style: "light",
color: "-"
});
},
data() {
return {
isShow: "none",
videoContext: null,
current: 0,
page: 1,
videoList: [
{
id: "000",
nickname: "老陈打码",

like: "3.5w",
share: "3821",
collect: "2988",
comment: "3475",
isLike: false,
pubtime: "2022-01-10 01:30",
headimg: "/shortvideo/",

};
},
methods: {
handleClick(e) {

});
},
onchange(event) {
// ()

if ( === - 1) {
++;
({
url: "/api/videos/getVideoList?obj=" + ({ page: , limit: 2 })
}, (ret, err) => {
// (ret)
// = ()
(item => (item))
if ( == 0) {
({
msg: '休息一下，视频很快会更新！'
})
}
})
}
&& ()
('#video' + ).$$getContext().then((context) => {
= context;
()
})
},
togglePause() {
()
},
togglePlay() {
()
},
onplay() {

},
onpause() {

},
onended() {

},
likeFn() {
[].isLike = ![].isLike;
},
shareFn() {
[].share++;
}
},
apiready() {
