需求：
1.首次进入APP给出弹窗提示是否存在最新版本APP，可选择更新或者取消
2.选择取消后，在使用期间不再弹出该弹窗
3.在设置中增加按钮，点击进行版本检测，再弹窗
效果图：
使用到的插件：APP升级，在线升级支持android、ios - DCloud 插件市场
二次开发效果好，可根据项目需求自行修改页面结构，静态图片
场景1：进入APP自动检测实现
1.App.vue中
export default {
globalData: {
autocheckupdate: false //是否开启自动检测
},onLaunch() {
// #ifdef APP
this.autocheckupdate = true //开启检测
uni.setStorageSync('autocheckupdate',this.autocheckupdate) //存入缓存
setTimeout(()=>{
this.autocheckupdate = false
uni.setStorageSync('autocheckupdate',this.autocheckupdate)
},2500) //这里我写的简单，2.5s后自动设置为不开启，可以根据项目需求来写
// #endif2.首页xxx.vue中
import ZyUpdate from '../../components/zy-upgrade/zy-upgrade.vue'components: {
ZyUpdate
},data() {
return {
autocheckupdate: uni.getStorageSync('autocheckupdate'),
updateurl: '', //后端检测版本接口地址
oldversion: '' //当前项目版本号
};
},<!-- #ifdef APP-PLUS -->
<zy-update
ref="zyupgrade"
:updateurl="updateurl"
:autocheckupdate="autocheckupdate"
:noticeflag="true"
:h5preview="true"
:oldversion="oldversion"
@showupdateTips="showupdatetips">
</zy-update>
<!-- #endif -->onLoad() {
// #ifdef APP-PLUS
plus.runtime.getProperty(plus.runtime.appid,(widgetInfo) => {
this.oldversion = widgetInfo.version //检测app版本
});
this.updateurl = 'xxx' //后端检测更新接口地址
// #endif
},showupdatetips(flag){
if(flag == 0){
uni.showToast({
title: '已经是最新版本了',
icon:'none'
});
}
},3.zy-upgrade.vue文件中，样式结构自己根据UI图修改，静态资源图片可以自行修改, 另外不要照抄appVersion这个接口，这是我自己封装的，copy没用，记得自己封装自己的接口，替换就好

场景2：手动点击按钮检测是否更新
这里就不需要像场景1一样用到autocheckupdate参数来开启检测，只需要在@click点击事件里调方法 this.$refs.zyupgrade.check_update()
<!-- #ifdef APP-PLUS -->
<zy-update
ref="zyupgrade"
:updateurl="updateurl"
:autocheckupdate="false"
:noticeflag="true"
:h5preview="true"
:oldversion="oldversion"
@showupdateTips="showupdatetips">
</zy-update>
<!-- #endif --><view class="info_item" @click="checkVersion" style="border-bottom: 1rpx #E6E6E6 solid;">
<text>版本号</text>
<view class="version">
<text class="tititi">{{oldversion}}</text>
<image
class="tototo"
src="https://xxx/my_back.png"
></image>
</view>
</view>checkVersion(){
console.log('检查版本');
this.$refs.zyupgrade.check_update()
},完成
