首先我先用vue2-admin-cli——我自己做的脚手架工具，创建两个vue-admin项目来演示，一个作为qiankun基座，另外一个就是我要引用的子应用。
全局安装脚手架 npm install -g vue2-admin-cli # or yarn global add vue2-admin-cli 创建项目 vue2-admin-cli init <project_name> 安装依赖 yarn 启动项目 yarn serve
运行起来就是这样的
现在我们开始分别改造基座qiankun-base和子应用qiankun-vue，我想达到的效果是主应用qiankun-base只保留header sider footer的一个基本layout的布局，content部分全部加载子应用
yarn add qiankun # 或者 npm i qiankun -S
修改package.json启动命令修改启动端口
"serve": "vue-cli-service serve --port 80 --open"
src/router/index.ts修改路由模式为history
const createRouter = () =>
new VueRouter({
mode: "history",
routes: routes as any,
});
修改vue.config.js 我这里之前用的路由模式是hash 上线配置了publicPath 导致改为history以后静态资源加载路径有问题所以修改
module.exports = {
// publicPath: "./",
devServer: {
disableHostCheck: true, // 关闭host检查
},
};在入口文件src/main.ts下注册微应用并启动：
import { registerMicroApps, start } from "qiankun";
registerMicroApps([
{
name: "qiankunVue",
entry: "//localhost:8080", 子应用的启动端口修改为8080，基座使用80，不要相同
container: "#qiankunVue", 加载子应用的容器
activeRule: "/qiankunVue", 路由匹配规则
},
]);
// 启动 qiankun
start();在你要放置子应用的位置增加一个容器用于加载子应用
src/components/layout/index.vue
<template>
<el-container direction="vertical" >
<Header />
<el-container >
<el-aside width="250px">
<Menu />
</el-aside>
<el-main>
<el-breadcrumb
separator-class="el-icon-arrow-right"
v-if="showBreadcrumb"
>
<template v-for="(route, index) in matchedRoutes">
<el-breadcrumb-item
v-if="
(route.meta && route.meta.breadcrumbTo === false) ||
index === matchedRoutes.length - 1
"
:key="route.path"
>
{{ route.meta.title }}
</el-breadcrumb-item>
<el-breadcrumb-item
v-else
:key="route.path"
:to="{ path: route.path }"
>
{{ route.meta.title }}
</el-breadcrumb-item>
</template>
</el-breadcrumb>
<!-- 本身的路由加载 -->
<router-view />
<!-- 子应用加载容器 -->
<div id="qiankunVue" />
</el-main>
</el-container>
</el-container>
</template>将主应用之前的路由配置进行修改，不渲染自己的内容了，因为要改成去加载子应用的内容才是我们想要的,我的左侧菜单栏sider也是用路由配置这份文件生成的，所以我只需要注释这些路由要渲染的components就行，让他只充当一个生成sider菜单栏的作用，但是注意要保留容器所在的layout，因为我的子应用加载容器在这里面，加载子应用之前你必须保证容器被加载了
src/router/config.ts
const routes: Array<IBaseRouter> = [
{
path: "/",
redirect: "/home",
hidden: true,
},
{
path: "/login",
name: "login",
hidden: true,
component: () => import("../views/Login.vue"),
},
//保证子应用加载时容器页面必须加载
{
path: "/qiankunVue/*",
name: "qiankunVue",
hidden: true,
component: Layout,
},
{
path: "/qiankunVue/home",
name: "home",
component: Layout,
redirect: "/qiankunVue/home/index",
meta: {
title: "首页",
icon: "el-icon-s-home",
},
children: [
{
path: "index",
name: "index",
hidden: true,
// component: () => import("../views/Home.vue"),
meta: {
title: "首页",
breadcrumb: false,
},
},
{
path: "bar/:width/:height",
name: "bar",
props: true,
hidden: true,
// component: () => import("@/components/echarts/Bar.vue"),
meta: {
title: "柱状图",
activeMenu: "/home/index",
},
},
{
path: "pie/:width/:height",
name: "pie",
props: true,
hidden: true,
// component: () => import("@/components/echarts/Pie.vue"),
meta: {
title: "饼图",
activeMenu: "/home/index",
},
},
{
path: "line/:width/:height",
name: "line",
props: true,
hidden: true,
// component: () => import("@/components/echarts/Line.vue"),
meta: {
title: "折线图",
activeMenu: "/home/index",
},
},
],
},
.....
{
path: "*",
redirect: "/error/404",
hidden: true,
},
];
export default routes;改完之后刷新看一看，这样基座项目就改造好了，保留了基本页面的框架，中间的内容到时候都由子应用来填充就行了
修改package.json启动命令修改启动端口
"serve": "vue-cli-service serve --port 8080 --open"
入口文件 src/main.ts 修改
let vm: any = null;
function render(props: any = {}) {
const { container } = props;
vm = new Vue({
router,
store,
render: (h) => h(App),
}).$mount(container ? container.querySelector("#app") : "#app");
}
// 在被qiankun引用时 修改运行时的 `publicPath`
if ((window as any).__POWERED_BY_QIANKUN__) {
__webpack_public_path__ = (window as any).__INJECTED_PUBLIC_PATH_BY_QIANKUN__;
}
// 独立运行时
if (!(window as any).__POWERED_BY_QIANKUN__) {
render();
}
导出三个生命周期函数
export async function bootstrap() {
console.log("[vue] vue app bootstraped");
}
export async function mount(props: any) {
console.log("[vue] props from main framework", props);
render(props);
}
export async function unmount() {
vm.$destroy();
vm.$el.innerHTML = "";
vm = null;
}
export default vm;src/router/index.ts修改路由模式并增加base（和主应用设置的activeRule一致）
const createRouter = () =>
new VueRouter({
mode: "history",
base: "/qiankunVue",
routes: routes as any
});打包配置修改（`vue.config.js`）
module.exports = {
devServer: {
disableHostCheck: true, // 关闭host检查
headers: {
"Access-Control-Allow-Origin": "*", // 防止加载时跨域
},
},
configureWebpack: {
output: {
library: "qiankunVue",
libraryTarget: "umd", // 把微应用打包成 umd 库格式
},
},
};基座和子应用都修改完以后刷新看看，控制台报错了
立马查看官方文档，发现是因为我的子应用加载容器在基座的某个路由页面即我的layout里面，文档里指出必须保证微应用加载时主应用这个路由页面也加载了，就很喜欢这种文档????????，于是立马改一改
注释之前qiankun-base注册子应用时的启动qiankun命令，改到路由页面layout里面启动
src/main.ts
// 启动 qiankun
//start();
src/components/layout/index.vue
import { start } from "qiankun";
mounted() {
if (!(window as any).qiankunStarted) {
(window as any).qiankunStarted = true;
start();
}
}重新刷新看看，成功了????????，多少有点舒服了
接下来要做的就是把子应用再改造一下，在qiankun中就只需要展示子应用content的内容，单独运行的时候为了方便调试我们就保留layout布局。看了这么久的官方文档，我当然知道用它就可以做出判断__POWERED_BY_QIANKUN__，思路很清晰，冲他????????
qiankun-vue
src/components/layout/index.vue
<template>
<el-container direction="vertical" v-if="isQiankun">
<el-main>
<el-breadcrumb
separator-class="el-icon-arrow-right"
v-if="showBreadcrumb"
>
<template v-for="(route, index) in matchedRoutes">
<el-breadcrumb-item
v-if="
(route.meta && route.meta.breadcrumbTo === false) ||
index === matchedRoutes.length - 1
"
:key="route.path"
>
{{ route.meta.title }}
<!-- {{ route.path }} -->
</el-breadcrumb-item>
<el-breadcrumb-item
v-else
:key="route.path"
:to="{ path: route.path }"
>
{{ route.meta.title }}
<!-- {{ route.path }} -->
</el-breadcrumb-item>
</template>
</el-breadcrumb>
<router-view />
</el-main>
</el-container>
<el-container direction="vertical" v-else>
<Header />
<el-container >
<el-aside width="250px">
<Menu />
</el-aside>
<el-main>
<el-breadcrumb
separator-class="el-icon-arrow-right"
v-if="showBreadcrumb"
>
<template v-for="(route, index) in matchedRoutes">
<el-breadcrumb-item
v-if="
(route.meta && route.meta.breadcrumbTo === false) ||
index === matchedRoutes.length - 1
"
:key="route.path"
>
{{ route.meta.title }}
<!-- {{ route.path }} -->
</el-breadcrumb-item>
<el-breadcrumb-item
v-else
:key="route.path"
:to="{ path: route.path }"
>
{{ route.meta.title }}
<!-- {{ route.path }} -->
</el-breadcrumb-item>
</template>
</el-breadcrumb>
<router-view />
</el-main>
</el-container>
</el-container>
</template>
<script lang="ts">
import { Vue, Component } from "vue-property-decorator";
import Header from "./Header.vue";
import Menu from "./Menu.vue";
// import { IBaseRouter } from "@/router/config";
@Component({
name: "Layout",
components: { Header, Menu },
})
export default class Layout extends Vue {
private get showBreadcrumb() {
return this.$route?.meta?.breadcrumbAll !== false;
}
private get matchedRoutes() {
return this.$route.matched?.filter(
(v) => v.meta?.title && v?.meta?.breadcrumb !== false
);
}
private get isQiankun() {
return (window as any).__POWERED_BY_QIANKUN__;
}
}
</script>
<style lang="less" scoped></style>看看效果 基座正常展示子应用
子应用单独运行也正常展示，并且丝毫不影响开发体验
