qiankun 主项目和子项目都是 vue2，部署在不同的服务器上，nginx 配置

1、主项目配置

1.1 micro.vue 组件

<template>
  <div id="container-sub-app"></div>
</template>

<script>
import { loadMicroApp } from 'qiankun';
import actions from '@/utils/actions.js';

export default {
  name: 'microApp',
  mixins: [actions],
  data() {
    return {
      microApp: null
    };
  },
  mounted() {
    const getMicroInfo = this.getMicroInfo();
    this.microApp = loadMicroApp(getMicroInfo, {
      singular: true
    });
  },
  beforeDestroy() {
    console.log('beforeDestroy...');
    this.microApp.unmount();
  },
  methods: {
    // 手动加载微应用
    getMicroInfo() {
      const appIdentifying = this.$route.path.split('/')[1];
      let data = {};
      const href = window.location.host;
      for (let i = 0; i < document.subApps.length; i++) {
        const element = document.subApps[i];
        if (element.activeRule.includes(appIdentifying)) {
          if (typeof element.entry !== 'string') {
            data = {
              ...element,
              entry: element.entry[href]
                ? element.entry[href]
                : Object.values(element.entry)[0]
            };
          } else {
            data = { ...element };
          }
          data.props = {
            token: {
              userInfo: {
                userName: '小明',
                userId: '123',
                date: new Date().toLocaleString()
              }
            }
          };
          data.activeRule = [appIdentifying];
          break;
        }
      }
      return data;
    }
  }
};
</script>

1.2 index.html 引入配置

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"
    />
    <link rel="icon" href="<%= BASE_URL %>favicon.ico" />
    <script src="<%= BASE_URL %>register-apps.js"></script>
    <title><%= webpackConfig.name %></title>
  </head>
  <body>
    <noscript>
      <strong
        >We're sorry but <%= webpackConfig.name %> doesn't work properly without
        JavaScript enabled. Please enable it to continue.</strong
      >
    </noscript>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

1.3 register-apps.js 配置

document.subApps = [
  {
    name: 'besFront',
    //entry: '//localhost:8086/bes-front/',// 本地调试
    entry: '/bes-front/',// 部署到服务器
    container: '#container-sub-app',
    activeRule: '/bes-front'
  }
];

1.4 路由配置

import Vue from 'vue';
import Router from 'vue-router';

Vue.use(Router);

import Layout from '@/layout';
import MicroApp from '@/components/microApp';

export const constantRoutes = [
  {
    path: '/login',
    component: () => import('@/views/login/index'),
    hidden: true
  },
  {
    path: '/404',
    component: () => import('@/views/404'),
    hidden: true
  },
  {
    path: '/dashboard',
    component: Layout,
    redirect: '/dashboard/index',
    children: [
      {
        path: 'index',
        name: 'Dashboard',
        component: () => import('@/views/dashboard/index'),
        meta: { title: 'Dashboard', icon: 'dashboard' }
      }
    ]
  },
  {
    path: '/',
    component: Layout,
    children: [
      {
        path: 'bes-front',
        component: MicroApp// 重点，用于加载子项目
      }
    ]
  }
  // 404 page must be placed at the end !!!
  // { path: '*', redirect: '/404', hidden: true }
];

const createRouter = () =>
  new Router({
    mode: 'history', // require service support
    base: '/parent/',// 部署在不同服务器上，主应用加前缀
    scrollBehavior: () => ({ y: 0 }),
    routes: constantRoutes
  });

const router = createRouter();

// Detail see: https://github.com/vuejs/vue-router/issues/1234#issuecomment-357941465
export function resetRouter() {
  const newRouter = createRouter();
  router.matcher = newRouter.matcher; // reset router
}

export default router;

2、子项目配置

2.1 main.js 配置

// 动态设置 publicPath
import './public-path';
import Vue from 'vue';
import App from './App.vue';
import router from './router';
import store from './store';
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

Vue.config.productionTip = false;
Vue.use(ElementUI);

let instance = null;
function render(props = {}) {
  console.log('子应用 render props::', props, 'instance====', instance);
  // sessionStorage.setItem('userInfo', JSON.stringify(props.token.userInfo));
  const { container } = props;

  instance = new Vue({
    router,
    store,
    render: (h) => h(App)
  }).$mount(container ? container.querySelector('#app') : '#app');
}

// 独立运行时
/* eslint-disable */
if (!window.__POWERED_BY_QIANKUN__) {
  render();
}

export async function bootstrap() {
  console.log('子应用 bootstrap ===========================');
}

let initialState = null;
export async function mount(props) {
  console.log('子应用 mount props ===============', props);
  sessionStorage.setItem('userInfo', JSON.stringify(props.token.userInfo));
  props.onGlobalStateChange((state, prev) => {
    // state: 变更后的状态; prev 变更前的状态
    console.log('子应用获取共享数据 state::', state, 'prev::', prev);
    // 接收主应用中的共享数据 并将其设置为全局变量
    Vue.prototype.$initialState = state;
  });
  props.setGlobalState({
    initialState:
      '子应用中修改主应用中的全局变量，实现住应用子应用间数据的双向双向通信'
  });

  render(props);
}
export async function unmount() {
  console.log('子应用 unmount==========');
  instance.$destroy();
  instance.$el.innerHTML = '';
  instance = null;
}

2.2 public-path 文件

if (window.__POWERED_BY_QIANKUN__) {
  /* eslint-disable @typescript-eslint/camelcase */
  __webpack_public_path__ = window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__;
}

2.3 vue.config.js 配置

'use strict';
const path = require('path');
const defaultSettings = require('./src/settings.js');
const proxyTable = require('./proxyTable');

function resolve(dir) {
  return path.join(__dirname, dir);
}

const name = defaultSettings.title || 'vue Admin Template'; // page title

// If your port is set to 80,
    // use administrator privileges to execute the command line.
// For example, Mac: sudo npm run
// You can change the port by the following methods:
// port = 9528 npm run dev OR npm run dev --port = 9528
const port = process.env.port || process.env.npm_config_port || 9528; // dev port

// All configuration item explanations can be find in https://cli.vuejs.org/config/
module.exports = {
  /**
   * You will need to set publicPath if you plan to deploy your site under a sub path,
   * for example GitHub Pages. If you plan to deploy your site to https://foo.github.io/bar/,
   * then publicPath should be set to "/bar/".
   * In most cases please use '/' !!!
   * Detail: https://cli.vuejs.org/config/#publicpath
   */
  publicPath: '/bes-front/',
  outputDir: 'dist',
  assetsDir: 'static',
  lintOnSave: process.env.NODE_ENV === 'development',
  productionSourceMap: false,
  devServer: {
    headers:{
        "Access-Control-Allow-Origin": "*",
    },
    port: port,
    open: true,
    proxy: proxyTable,
    overlay: {
      warnings: false,
      errors: true
    }
  },
  configureWebpack: {
    // provide the app's title in webpack's name field, so that
    // it can be accessed in index.html to inject the correct title.
    name: name,
    output:{
        library: `besFront`,// 主应用
        libraryTarget: "umd",// 把微应用打包成 umd 库格式
        jsonpFunction: `webpackJsonp_besFront`,// webpack5 需要把 jsonpFunction 替换成 chunkLoadingGlobal
    },
    resolve: {
      alias: {
        '@': resolve('src')
      }
    }
  },
  chainWebpack(config) {
    // it can improve the speed of the first screen, it is recommended to turn on preload
    config.plugin('preload').tap(() => [
      {
        rel: 'preload',
        // to ignore runtime.js
        // https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli-service/lib/config/app.js#L171
        fileBlacklist: [/\.map$/, /hot-update\.js$/, /runtime\..*\.js$/],
        include: 'initial'
      }
    ]);

    // when there are many pages, it will cause too many meaningless requests
    config.plugins.delete('prefetch');

    // set svg-sprite-loader
    config.module.rule('svg').exclude.add(resolve('src/icons')).end();
    config.module
      .rule('icons')
      .test(/\.svg$/)
      .include.add(resolve('src/icons'))
      .end()
      .use('svg-sprite-loader')
      .loader('svg-sprite-loader')
      .options({
        symbolId: 'icon-[name]'
      })
      .end();

    config.when(process.env.NODE_ENV !== 'development', (config) => {
      config
        .plugin('ScriptExtHtmlWebpackPlugin')
        .after('html')
        .use('script-ext-html-webpack-plugin', [
          {
            // `runtime` must same as runtimeChunk name. default is `runtime`
            inline: /runtime\..*\.js$/
          }
        ])
        .end();
      config.optimization.splitChunks({
        chunks: 'all',
        cacheGroups: {
          libs: {
            name: 'chunk-libs',
            test: /[\\/]node_modules[\\/]/,
            priority: 10,
            chunks: 'initial' // only package third parties that are initially dependent
          },
          elementUI: {
            name: 'chunk-elementUI', // split elementUI into a single package
            priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
            test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm
          },
          commons: {
            name: 'chunk-commons',
            test: resolve('src/components'), // can customize your rules
            minChunks: 3, //  minimum common number
            priority: 5,
            reuseExistingChunk: true
          }
        }
      });
      // https:// webpack.js.org/configuration/optimization/#optimizationruntimechunk
      config.optimization.runtimeChunk('single');
    });
  }
};

2.3 接口需加前缀区分

const uri = '/child1/api';

// 部门新增
export async function departmentAddApi(params) {
  return $ajax.post(`${uri}/department/add`, params);
}

3、主项目和子项目部署在不同的服务器上，其中主应用路由使用history模式，子应用路由使用hash模式，子应用所有的静态资源及接口统一从主应用进行转发，nginx 配置如下：

主应用 nginx 配置：

locatoin /parent/ {
    root /opt/parent;
    index index.html index.htm;
    try_files $uri $uri/ /index.html;
}


location /bes-front/ {
    proxy_pass http://子应用ip/bes-front/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header REMOTE_HOST $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}


location /bes-front/static/ {
    proxy_pass http://子应用ip/bes-front/static/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header REMOTE_HOST $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}


location /child1/ {
    proxy_pass http://子应用ip/child1/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header REMOTE_HOST $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

注：使用的下面这种部署方式，主应用代码放在主应用服务器的/opt/parent目录下，子应用代码放在子应用服务器的/opt/bes-front目录下面，重点是主应用的路由要加前缀进行区分，其次，子应用的所有接口转发都统一从主应用转发到子应用，因此子应用的接口要增加前缀进行区分
