最近用uniapp写了一个安卓壳子做app，遇到一个需求，校验app版本并更新
通过对比线上版本号和app自己的版本号的差异，唤起更新弹窗
相关代码
App.vue
export default {
onLaunch: function() {
this.checkVersion()
},
onShow: function() {
console.log('App Show')
},
onHide: function() {
console.log('App Hide')
},
methods: {
checkVersion() {
//https://www.xxxx.com.cn/api/App/GetAppVersion 用来获取app信息的接口
uni.request({
url: 'https://www.xxxx.com.cn/api/App/GetAppVersion',
method: 'get',
data: {},
header: {
'Content-Type': 'application/json', // 设置请求头
},
success: (res) => {
console.log('success', res)
if (res.data.Flag == 1) {
let {
Data
} = res.data
if (Data.VersionCode) {
plus.runtime.getProperty(plus.runtime.appid, function(wgtinfo) {
const newVersionCode = Data.VersionCode; //线上最新版本号
const selfVersionCode = wgtinfo.versionCode //当前APP应用版本
console.log('newVersionCode:',newVersionCode)
console.log('selfVersionCode:',selfVersionCode)
//线上版本号和当前不一样，进行在线升级
if (selfVersionCode != newVersionCode) {
let platform = uni.getSystemInfoSync().platform //手机平台
//安卓手机弹窗升级
if (platform === 'android') {
uni.navigateTo({
url: '/pages/upgrade/index'
})
}
}
});
}
}
},
fail: (err) => {
console.log('err', err)
},
});
}
}
}
