uniapp 主应用集成 vue微应用

乾坤官方文档

主应用为uniapp

在主应用安装qiankun框架

yarn add qiankun 
#或者
npm install qiankun

因为我们需要动态传递数据，则使用loadMicroApp方法动态加载
pages/work/preview/index页面文件

<template><view class="preview-container"><view class="micro-wrap"><div id="micro-container"></div></view></view>
</template><script>
let microApp = null
import { loadMicroApp } from 'qiankun';
import { getInfo } from '@/api/login'
import actions from '../../../share/actions';
export default {components: {},data() {return {loading: false,previewId: 1}},async onLoad() {await this.init()},async onUnload() {if (microApp) {await microApp.unmount()microApp = null}},methods: {async init() {this.loading = trueactions.setGlobalState({previewId: this.previewId})await this.mountSub()},async mountSub() {const resp = await getInfo();// 获取系统信息const systemInfo = uni.getSystemInfoSync();microApp = loadMicroApp({name: 'test',entry: 'http://localhost/', //不要写路由 hashcontainer: '#micro-container',props: {userInfo: resp.data,systemInfo,onGlobalStateChange: actions.onGlobalStateChange,setGlobalState: actions.setGlobalState},sandbox: {experimentalStyleIsolation: true //强制性的样式沙箱隔离}})await microApp.mountPromisethis.loading = false}}
}
</script><style scoped>
.micro-wrap {overflow: hidden;height: calc(100vh - 44px);width: 100%;
}
</style>

share/actions.js文件

import {initGlobalState
} from 'qiankun';// 主应用中注册全局事件
// 设置全局状态
const initialState = {currentTab: 0,zoomScale: 1,mobile: true
};
// 创建全局状态实例并导出
const actions = initGlobalState(initialState);
// 监听全局状态变化（可选）actions.onGlobalStateChange((newState, prev) => {console.log('主应用监听到全局状态变化:', newState, prev);});
export default actions;

微应用

1.在 src 目录新增 public-path.js：

if (window.__POWERED_BY_QIANKUN__) {__webpack_public_path__ = window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__;
}

2.入口文件 main.js 修改，为了避免根 id #app 与其他的 DOM 冲突，需要限制查找范围。

import './public-path'; // 需要放在第一行，不然icon图标会显示不出不来
import store from './store'
import { isMobile } from '@/utils'
let instance = null
/** ================微前端配置================ */
// 如果是在乾坤里面加载，则子应用应该跳过默认的加载逻辑，让主应用来控制当前应用的加载（匹配到子应用的路由标识）
if (!window.__POWERED_BY_QIANKUN__) {render({});
}
function render(props = {}) {const { container, userInfo, systemInfo } = propsif (userInfo) {store.dispatch('setUserInfo', userInfo)}if (systemInfo) {// 手机样式if (isMobile(systemInfo.ua)) {document.body.classList.add('ua-mobile');} else {document.body.classList.add('ua-pc');}}// 监听主应用推过来的全局状态（true = 首次立即触发一次）props.onGlobalStateChange && props.onGlobalStateChange((state, prev) => {//更新 vuex / 组件状态 / 重新拉数据等store.dispatch('qiankun/setQkState', state)}, true) // true 表示进来就触发一次// 子应用也可以反向通知主应用// props.setGlobalState && props.setGlobalState({ childReady: true })instance = new Vue({el: container ? container.querySelector('#app') : '#app',router,store,render: h => h(App)})
}// qiankun 生命周期
export async function bootstrap() {console.log('app bootstraped');
}
export async function mount(props) { render(props) }
export async function unmount() {instance.$destroy()instance.$el.innerHTML = ''instance = null
}

src\store\modules\qiankun.js状态文件

const state = () => ({qiankunState: {}   // 主应用下发的全局状态
})
const mutations = {SET_QK_STATE(state, payload) {state.qiankunState = { ...state.qiankunState, ...payload }}
}
const actions = {setQkState({ commit }, payload) {commit('SET_QK_STATE', payload)}
}
export default { namespaced: true, state, mutations, actions }

监听状态变化,在vue文件里面加下下面的代码

 computed: {...mapState({// 箭头函数会使代码更简练currentTab: state => state.qiankun.qiankunState.currentTab,zoomScale: state => state.qiankun.qiankunState.zoomScale})},watch: {currentTab(newVal, oldVal) {conslole.log(newVal, oldVal)},zoomScale(newVal, oldVal) {conslole.log(newVal, oldVal)}},

3.打包配置修改（vue.config.js）：

const packageName = require('./package.json').name;
module.exports = {devServer: {headers: {'Access-Control-Allow-Origin': '*',},},configureWebpack: {output: {library: `${packageName}-[name]`,libraryTarget: 'umd', // 把微应用打包成 umd 库格式jsonpFunction: `webpackJsonp_${packageName}`, // webpack 5 需要把 jsonpFunction 替换成 chunkLoadingGlobal},},
};

4.新建路由

{path: '/pages',component: Layout,hidden: true,redirect: 'noredirect',children: [{meta: {title: '微前端',},path: 'work/preview/index',// component: (resolve) => require(['@/views/hardware/manage/index'], resolve),component: (resolve) => require(['@/views/app/preview'], resolve),name: 'AppPreview',meta: {title: '微前端页面', icon: '', noCache: true}}]},
