1. 主应用改造

修改activeRule

如： 

[
  {
    name: "ReactMicroApp",
    entry: process.env.VUE_APP_REACT_MICRO_APP,
    container: "#frame",
    activeRule: "/#/microApp/react",
  },
  {
    name: "VueMicroApp",
    entry: process.env.VUE_APP_VUE_MICRO_APP,
    container: "#frame",
    activeRule: "/#/microApp/vue",
  }
]

路由部分修改

2. vue子应用修改 

router修改

import Home from '@/pages/home/index.vue';

let prefix = window.__POWERED_BY_QIANKUN__ ? '/microApp/vue/' : '/';

const routes = [
  {
    path: prefix == '/' ? prefix : prefix.substring(0, prefix.length - 1),
    name: 'Home',
    component: Home
  },
  {
    path: prefix + 'about',
    name: 'About',
    component: () => import('@/pages/about/index.vue')
  }
]

export default routes;

修改main.js中VueRouter mode及增加监听beforeEach事件

//...省略

let instance = null
let router = null

/**
 * 渲染函数
 * 两种情况：主应用生命周期钩子中运行 / 微应用单独启动时运行
 */
function render() {
  // 在 render 中创建 VueRouter，可以保证在卸载微应用时，移除 location 事件监听，防止事件污染
  router = new VueRouter({
    // 运行在主应用中时，添加路由命名空间 /vue
    // base: window.__POWERED_BY_QIANKUN__ ? "/vue" : "/",
    // mode: "history",
    routes,
  });
  if (window.__POWERED_BY_QIANKUN__) {
    router.beforeEach((to, from, next) => {
      if (!to.path.includes("/microApp")) {
        next({
          path: "/microApp/vue" + (to.path == "/" ? "" : to.path) 
        })
      } else {
        next()
      }
    })
  }

  // 挂载应用
  instance = new Vue({
    router,
    render: (h) => h(App),
  }).$mount("#app")
}

// 独立运行时，直接挂载应用
if (!window.__POWERED_BY_QIANKUN__) {
  render()
}

//...省略
