1. 下载安装"qiankun": “^2.10.13”

参考官网地址

2. 手动调用qiankun,使用vue脚手架搭建的项目

1. 主项目配置（我使用的是手动调用乾坤，在指定页面显示内容）

1. 要使用的页面中引入乾坤

<template><div class="xin"><p> 个人项目</p><keep-alive><div id="baixianHome"></div></keep-alive><!--xinHome 为放置子项目的盒子  --></div>
</template><script>
import { loadMicroApp, start } from 'qiankun';//引入手动调用方法export default {name: 'XinVue2',data() {return {}},created() {this.$nextTick(() => {// hash模式下配置const getActiveRule = (hash) => (location) => location.hash.startsWith(hash);this.vueApp = loadMicroApp({name: 'qiankun-children',entry: '//localhost:8081/',container: '#xinHome',activeRule: getActiveRule('#/'),});//启动乾坤函数start({ singular: false });})},beforeDestroy(){console.log( this.vueApp.unmount({ name: 'qiankun-children' }))this.vueApp.unmount({ name: 'qiankun-children' });},methods: {}
}

2. router设置

1. router/index.js文件配置

import Vue from 'vue'
import VueRouter from 'vue-router';
Vue.use(VueRouter)const router = new VueRouter({base: window.__POWERED_BY_QIANKUN__ ? '/qiankun-children/' : '/',  //使用 history模式必须配置mode: 'history',routes: [{path: '/xin',name: 'xin',component: () => import('@/views/xin-vue2/home'),}, {path: '/mq',name: 'mq',component: () => import('@/views/mq-vue2/home'),}],
});
export default router

2. main.js配置 引入并使用VueRouter

import VueRouter from 'vue-router';
import router from './router/index'
Vue.config.productionTip = false
Vue.use(VueRouter)
new Vue({router,render: h => h(App),
}).$mount('#appAdmin')

3. 文件目录结构
   

2. 子项目配置（我用的hash模式）

1. 在src目录下新建public-path.js文件

__webpack_public_path__ = window.__POWERED_BY_QIANKUN__? window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__: `http://localhost:8081/`; // 填写你当前子项目的实际部署地址

1. main.js 配置

import './public-path';//要放最上边
import Vue from 'vue';
import VueRouter from 'vue-router';
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import App from './App.vue';
import store from './store';
import Home from './views/home/index.vue'Vue.config.productionTip = false;
Vue.use(ElementUI);
Vue.use(VueRouter)
let router = null;
let instance = null;
function render(props = {}) {const { container } = props;router = new VueRouter({scrollBehavior: () => ({ y: 0 }),routes:[{path: '/home',name: 'Home',component: Home}],});instance = new Vue({router,store,render: (h) => h(App),}).$mount(container ? container.querySelector('#app') : '#app');
}// 独立运行时
if (!window.__POWERED_BY_QIANKUN__) {render();
}export async function bootstrap() {console.log('[vue] vue app bootstraped');
}
export async function mount(props) {console.log('[vue] props from main framework', props);render(props);
}
export async function unmount() {instance.$destroy();instance.$el.innerHTML = '';instance = null;router = null;
}

2. vue.config.js 配置

const { defineConfig } = require('@vue/cli-service')
const packageName = require('./package.json').name;
module.exports = defineConfig({transpileDependencies: true,devServer: {headers: {'Access-Control-Allow-Origin': '*',},},configureWebpack: {output: {library: `${packageName}-[name]`,libraryTarget: 'umd',chunkLoadingGlobal: `webpackJsonp_${packageName}`,publicPath: '/'},},
})

3. 运行后使用

1. 先运行主项目在运行子项目

2. 首页效果
   

3. 进入调用乾坤页面
   地址：http://localhost:8081/xin#/
   

4. 使用子项目路由，进入子项目home页面
   地址：http://localhost:8081/xin#/home
   

3. 手动调用qiankun,子项目是存在的旧项目修改

1. main.js 配置修改（添加一下）

let router = null;
let instance = null;
function render(props = {}) {const { container } = props;router = homeRoutesinstance = new Vue({router,render: (h) => h(App),}).$mount(container ? container.querySelector('#app') : '#app');
}// // 独立运行时
if (!window.__POWERED_BY_QIANKUN__) {render();
}export async function bootstrap() {console.log('[vue] vue app bootstraped');
}
export async function mount(props) {console.log('[vue] props from main framework', props);render(props);
}
export async function unmount() {instance.$destroy();instance.$el.innerHTML = '';instance = null;router = null;
}
// 微应用中增加 update 钩子以便主应用手动更新微应用
export async function update(props) {render(props);
}

2. router.js 配置修改（添加一下）

3. 添加vue.config.js 配置

4. 运行后使用

4 报错：

1.报错一：static/fonts/element-icons.535877f.woff:1 GET http://localhost:8080/static/fonts/element-icons.535877f.woff net::ERR_ABORTED 404 (Not Found)

默认情况下沙箱可以确保单实例场景子应用之间的样式隔离，但是无法确保主应用跟子应用、或者多实例场景的子应用样式隔离。当配置为 {
strictStyleIsolation: true } 时表示开启严格的样式隔离模式。这种模式下 qiankun
会为每个微应用的容器包裹上一个 shadow dom 节点，从而确保微应用的样式不会对全局造成影响。

该项目未上线使用，因此不知道打包后会不会有问题
