【Vue 開發實戰】實戰篇 # 33：更加精細化的權限設計（權限元件、權限指令）

說明

【Vue 開發實戰】學習筆記。

效果

實作兩種方式實作權限元件的控制，比如下面兩個地方的按鈕控制，如果是user使用者，就沒有權限控制

函數式元件

<script>import { check } from '../utils/auth';
export default {
    functional: true,
    props: {
        authority: {
            required: true,
            type: Array
        },
    },
    render(h,) {
        const { props, scopedSlots } = context;
        return check(props.authority) ? scopedSlots.default() : null;
    }
}</script>      

插件方式的指令

import { check } from '../utils/auth';

function install(Vue, options = {}) {
    Vue.directive(options.name || "auth", {
        inserted(el,) {
            if(!check(binding.value)) {
                el.parentNode && el.parentNode.removeChild(el);
            }
        }
    })
}

export default {install};      

全局注冊

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";

import { Button, Layout, Icon, Drawer, Radio, Menu } from "ant-design-vue";
import Authorized from "./components/Authorized.vue";
import Auth from "./directives/auth";

Vue.config.productionTip = false;

Vue.use(Button);
Vue.use(Layout);
Vue.use(Icon);
Vue.use(Drawer);
Vue.use(Radio);
Vue.use(Menu);

Vue.component("Authorized", Authorized);
Vue.use(Auth);

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount("#app");      

使用

<a-icon
    v-auth="['admin']"
    class="trigger"
    :type="collapsed ? 'menu-unfold' : 'menu-fold'"
    @click="collapsed = !collapsed"
></a-icon>

<Authorized :authority="['admin']">
    <SettingDrawer />
</Authorized>
