web项目当页面检测到需要更新,然后弹框提示是否更新(刷新页面)这种可以通过纯前端实现也可以通过接口实现
- 接口实现:通过调用接口轮询和本地的版本号比较,检查是否需要弹框提示更新
- 纯前端实现:项目打包时配置一个版本号然后和本地的版本号轮询比较,检查是否需要弹框提示更新
实现方案
当用户在项目所在的页面时轮询请求,然后在离开页面时停止轮询,再次切回来再次启动轮询,
如果超过轮询的最大次数后,停止轮询。
当请求的版本号大于本地的,或者本地版本号为空,则弹框提示需要更新
效果图
一、纯前端实现
打包配置版本号
const versionNumber = '1.1.0'
const { dependencies, devDependencies, name, version } = pkg
export const __APP_INFO__ = {
pkg: { dependencies, devDependencies, name, version },
lastBuildTime: dayjs().format('YYYY-MM-DD HH:mm:ss'),
checkUpdateVersion: versionNumber
}
vite.config.ts 启用配置
defineConfig {
...
define: {
__APP_INFO__: JSON.stringify(__APP_INFO__)
}
...
}
版本号本地存储和比较
import { setStorage, getStorage } from '@/utils/storage'
import { getCheckUpgrade } from '@/api/auth'
const kCheckUpdateVersion = 'checkUpdateVersion'
const { checkUpdateVersion } = __APP_INFO__
// 方式一: 通过build\info.ts 配置的版本号和本地进行比较
export const checkUpgrade = () => {
const version = getVersion()
let needUpgrade = false
if ((version && version !== checkUpdateVersion) || !version) {
needUpgrade = true
}
return needUpgrade
}
export const getVersion = () => {
return getStorage(kCheckUpdateVersion)
}
export const setVersion = (newVersion = checkUpdateVersion) => {
setStorage(kCheckUpdateVersion, newVersion)
}
轮询工具类
let activeCount: number = 0
const MAX_INACTIVE_COUNT: number = 5
const MAX_INACTIVE_COUNT_HIDDEN: number = 1
let pollingInterval: NodeJS.Timeout | null = null
const normalInterval = 1000 * 60 * 30
const isLimitTimer = true
export function startPolling(callback: () => void, interval: number = normalInterval): void {
// 首次执行
callback()
pollingInterval = setInterval(() => {
if (document.visibilityState === 'visible') {
if (isLimitTimer) {
activeCount++
if (activeCount >= MAX_INACTIVE_COUNT) {
stopPolling()
}
} else {
activeCount = 0
}
callback() // 执行轮询任务的回调函数
} else {
activeCount++
if (activeCount >= MAX_INACTIVE_COUNT_HIDDEN) {
stopPolling()
}
}
}, interval)
}
export function stopPolling(): void {
if (pollingInterval) {
clearInterval(pollingInterval)
pollingInterval = null
}
}
export function visibilityChange(callback: () => void, interval: number = normalInterval): void {
document.addEventListener('visibilitychange', () => {
if (document.visibilityState === 'visible') {
activeCount = 0
stopPolling()
// 页面可见时重新开始轮询
startPolling(callback, interval)
} else {
activeCount++
if (activeCount >= MAX_INACTIVE_COUNT_HIDDEN) {
stopPolling()
}
}
})
}
app.vue 轮询判断是否需要更新
onMounted(() => {
startPolling(() => {
state.needUpgrade = checkIsUpgrade()
console.log('needUpgrade111', JSON.stringify(state.needUpgrade))
})
visibilityChange(() => {
state.needUpgrade = checkIsUpgrade()
console.log('needUpgrade222', JSON.stringify(state.needUpgrade))
})
})
const checkIsUpgrade = () => {
let needUpgrade = false
if (route.path !== '/login') {
needUpgrade = checkUpgrade()
}
return needUpgrade
}
二、接口实现
接口格式
{
code: 20000,
msg: 'success',
data: {
isForceUpgrade: false,
version: '2.1.0',
descList: ['1. 新增xxx功能', '2. 优化xxx功能', '3. 修复xxx功能']
}
}
请求版本信息和本地比较
/**
* @description: 比较版本号
* @param {string} version1
* @param {string} version2
* @return {*} version1>version2 返回 1;如果小于返回 -1;如果相等 返回 0
*/
export function compareVersions(version1: string, version2: string): number {
const parts1: number[] = version1.split('.').map((part) => parseInt(part))
const parts2: number[] = version2.split('.').map((part) => parseInt(part))
const maxLength: number = Math.max(parts1.length, parts2.length)
for (let i = 0; i < maxLength; i++) {
const num1: number = parts1[i] || 0
const num2: number = parts2[i] || 0
if (num1 > num2) {
return 1
} else if (num1 < num2) {
return -1
}
// 如果相等,则继续比较下一个部分
}
return 0 // 如果版本号完全相等
}
export function requestCheckUpgrade() {
return new Promise((resolve, reject) => {
getCheckUpgrade()
.then((res) => {
if (res.code === 20000) {
var data = JSON.parse(JSON.stringify(res.data))
let needUpgrade = false
const version = getVersion()
// console.log('version', JSON.stringify(version))
// console.log('data.version', JSON.stringify(data.version))
// console.log('checkUpdateVersion', JSON.stringify(checkUpdateVersion))
// console.log('needUpgrade', compareVersions(data.version, version ? version : checkUpdateVersion))
if (compareVersions(data.version, version ? version : checkUpdateVersion) === 1) {
needUpgrade = true
}
var dict = { needUpgrade: needUpgrade, upgradeData: data }
resolve(dict)
} else {
reject(res.msg)
ElMessage.warning(res.msg)
}
})
.catch((err) => {
reject(err)
})
})
}
app.vue 轮询调用获取版本信息的请求和弹框显示
<UpgradeDialog v-model:is-show="needUpgrade" :upgrade-data="upgradeData" />
import { useRoute } from 'vue-router'
const route = useRoute()
import UpgradeDialog from '@/components/upgrade-dialog/index.vue'
import { checkUpgrade, startPolling, visibilityChange, requestCheckUpgrade } from '@/components/upgrade-dialog/upgradeUtils'
const state = reactive({
needUpgrade: false,
upgradeData: {}
})
const { needUpgrade, upgradeData } = toRefs(state)
onMounted(() => {
startPolling(() => {
getCheckUpgrade('startPolling')
})
visibilityChange(() => {
getCheckUpgrade('visibilityChange')
})
})
const getCheckUpgrade = (type: 'startPolling' | 'visibilityChange') => {
// if (route.path === '/login') {
// return
// }
requestCheckUpgrade()
.then((data: any) => {
state.needUpgrade = data.needUpgrade
state.upgradeData = data.upgradeData
if (type === 'startPolling') {
console.log('needUpgrade111', JSON.stringify(data))
} else {
console.log('needUpgrade222', JSON.stringify(data))
}
})
.catch((err) => {
console.log('err', JSON.stringify(err))
})
}
注意:点击弹框确认按钮刷新页面并把最新的版本号保存到本地
这是弹框组件内的点击按钮事件
if (props.upgradeData && props.upgradeData.version) {
setVersion(props.upgradeData.version)
} else {
setVersion()
}
window.location.reload()
