    项目背景

    图片

    前端开发过程中不可避免会用到图片、视频等多媒体物料，常见的处理方案通常会进行动静分离，将图片等资源放置在图床上，除了使用业界常用的图床资源，比如：七牛云、微博图床等，除了借助第三方图床外，我们也可以自己搭建一个图床，为团队业务开发提供更好的基础服务，提升开发体验及效率。本文旨在回顾总结下自建图床的前端部分实现方案，希望能够给有类似需求的同学一些借鉴和方案。

    方案

    前端部分架构选型，考虑到Vue3即将成为主版本，作为前端基建侧的应用，考虑想要使用Vue3全家桶来进行前端侧的相关实现，这里使用了vite(vue-template-ts)+vue3+vuex@next+vue-router@next的使用方案，也为vite的打包构建进行一步的技术预（cai）研（keng）。（ps：vite确实快，但是目前直接上工业环境还需要考量，还有不少坑，个人认为跨语言的前端工程化可能会是后续前端工程化的发展方向）

    实践

    图片

    图片

    前端图床涉及到权限验证，对于获取图片不进行认证确认，而对于需要进行上传及删除图片操作会需要进行登录鉴权

    源码

    vue3中可以通过class以及template两种方案来书写，使用composition-api的方案，个人建议还是使用class-component更加舒服，也更像react的写法，这里夹杂使用了composition-api和options-api的使用，目前vue是兼容的，对于从vue2中过来的同学，可以逐步去适应composition-api的写法，然后逐步按照hooks的函数式的思路去进行前端的业务实现

    vite.config.ts

    vite构建相关的一些配置，可以根据项目需求进行环境配置

    const path = require('path')
// vite.config.js # or vite.config.ts
console.log(path.resolve(__dirname, './src'))

module.exports = {
  alias: {
    // 键必须以斜线开始和结束
    '/@/': path.resolve(__dirname, './src'),
  },
  /**
   * 在生产中服务时的基本公共路径。
   * @default '/'
   */
  base: './',
  /**
   * 与“根”相关的目录，构建输出将放在其中。如果目录存在，它将在构建之前被删除。
   * @default 'dist'
   */
  outDir: 'dist',
  port: 3000,
  // 是否自动在浏览器打开
  open: false,
  // 是否开启 https
  https: false,
  // 服务端渲染
  ssr: false,
  // 引入第三方的配置
  //   optimizeDeps: {
  //     include: ["moment", "echarts", "axios", "mockjs"],
  //   },
  proxy: {
    // 如果是 /bff 打头，则访问地址如下
    '/bff/': {
      target: 'http://localhost:30096/',// 'http://10.186.2.55:8170/',  
      changeOrigin: true,
      rewrite: (path) => path.replace(/^\/bff/, ''),
    }
  },
  optimizeDeps: {
    include: ['element-plus/lib/locale/lang/zh-cn', 'axios'],
  },
}

    Page.vue

    每个子项目页面的展示，只需要一个组件，进行不同的数据渲染即可

    <template>
  <div class="page-header">
    <el-row>
      <el-col :span="12">

          @back="handleBack"
        />
      </el-col>
      <el-col :span="12">
        <section class="header-button">
          <!-- <el-button class="folder-add" :icon="FolderAdd" @click="handleFolder" >新建文件夹</el-button> -->
          <el-button class="upload" :icon="Upload" type="success" @click="handleImage">上传图片</el-button>
        </section>
      </el-col>
    </el-row>
  </div>
  <div class="page">
    <el-row :gutter="10">
      <el-col v-for="(item, index) in cards" :xs="12" :sm="8" :md="6" :lg="4" :xl="4">
        <Card
          @next="handleRouteView(item.ext, item.name)"
          @delete="handleDelete"
          :name="item.name"
          :src="item.src"
          :ext="item.ext"
          :key="index"
        />
      </el-col>
    </el-row>
    <el-pagination
      layout="sizes, prev, pager, next, total"
      @size-change="handleSizeChange"

      :current-page.sync="pageNum"
      :page-size="pageSize"
      :total="total"

    routes.ts

    vue-router@next中的动态路由方案略有不同，有类似rank的排名机制，具体可以参考vue-router@next的官方文档

    import { WrapperLayouts } from '../components';
import menuMap from './menuMap'
// 1. 定义路由组件， 注意，这里一定要使用 文件的全名（包含文件后缀名）
const routes = [
    { 
        path: "/",
        component: WrapperLayouts,
        redirect: `/page/${Object.keys(menuMap)[0]}`,
        children: [
            {
                path: '/page/:id',
                name: 'page',
                component: () => import('../views/Page.vue'),
                children: [
                {
                    path: '/page/:id(.*)*',
                    // redirect: `/page/${Object.keys(menuMap)[0]}`,
                    name: 'pageno',
                    component: () => import('../views/Page.vue')
                }
                ]
            }
        ]
    },
];

export default routes;
    import {createRouter, createWebHashHistory} from 'vue-router';

import { routes } from '../config';


// Vue-router新版本中，需要使用createRouter来创建路由
export default  createRouter({
  // 指定路由的模式,此处使用的是hash模式
  history: createWebHashHistory(),
  routes // short for `routes: routes`
})

    Aside.vue

    结合路由进行左边侧边栏的路由跳转及显示

    <template>
  <div class="aside">
    <el-menu @select="handleSelect" :default-active="Array.isArray($route.params.id) ? $route.params.id[0] : $route.params.id">
      <el-menu-item v-for="(menu, index) in menuLists" :index="menu.id" >
        <span>{{menu.label}}</span>
      </el-menu-item>
    </el-menu>
  </div>
</template>

<script lang="ts">
import {
  computed,
  defineComponent,
  getCurrentInstance,
  onMounted,
  reactive,
  ref,
  toRefs,
} from 'vue';

export default defineComponent({
  name: 'Aside',
  props: {
    menuMap: {
      type: Object,
      default: () => {}
    }
  },
  components: {

  },
  methods: {
    handleSelect(e) {
      console.log('$route', this.$route.params.id)
      console.log('select', e)
      this.$router.push(`/page/${e}`)
    }
  },
  setup(props, context) {
    console.log('props', props.menuMap)
    //引用全局变量
    const { proxy } = getCurrentInstance();

    const menuMap = props.menuMap;

    let menuLists = reactive([]);

    //dom挂载后
    onMounted(() => {
      handleMenuLists();
    });

    function handleMenuLists() {
      (proxy as any).$http.get('/bff/imagepic/bucket/listBuckets').then(res => {
        console.log('listBuckets', res);
        if(res.data.success) {
          res.data.data.forEach(element => {
            menuMap[`${element.name}`] && menuLists.push({
              id: element.name,
              label: menuMap[`${element.name}`]
            }) 
          })
        }
      })
    }


    return {
      ...toRefs(menuLists),
      handleMenuLists,
      menuLists
    };
  }
})
</script>

<style lang="scss">
.aside {
  height: 100%;
  background-color: #fff;
  width: 100%;
  border-right: 1px solid #d7d7d7;
}
</style>
