动态路由

import router from '@/router/index'
const modules = import.meta.glob('../views/**/*.vue')
//导航守卫+动态路由
//to是要跳转到的页面
//form是跳转前的页面
//next是不做任何阻拦允许跳转
router.beforeEach((to, from, next) => {
    //pinia中获取用户登录状态
    const CounterStore = useCounterStore();
    //是否为登录状态,并且令牌不为空
    if (CounterStore.isLogin && localStorage.getItem('token')) {
        //如果路由是登录页面则跳转到主页
        if (to.path === '/') {
            next({
                path: '/Main'
            })
        }
        //不为登录页面
        else {
            //如果路由不存在则添加路由
            if (to.name === undefined) {
                const routes = JSON.parse(localStorage.getItem('apidto') as string);
                addRoutesRecursively(routes);
                next({ ...to, replace: true })
            }
            next();
        }
    }
    //如果没有登录
    else {
        if (to.path === '/') {
            next()
        }
        else {
            next({
                path: '/'
            })
        }
    }
})
//递归获取用户
function addRoutesRecursively(routes: any[]) {
    routes.forEach((route) => {
        // 假设 route 可能包含 children 属性  
        if (route.children) {
            // 递归调用自身来处理 children  
            addRoutesRecursively(route.children);
        }
        // 添加当前路由
        else {
            router.addRoute('Main', {
                path: route.roUrl,
                name: route.roName,
                component: modules['../views' + route.moUrl] // 注意这里可能需要根据实际情况调整路径拼接方式  
            });
        }
    });
}

动态按钮

//pinia状态管理	
import { useUserStore } from '../stores/User'
import type { Directive, DirectiveBinding } from "vue";

//权限按钮自定义事件

export const hasPerm: Directive = {
    mounted(el: HTMLElement, binding: DirectiveBinding) {
        // DOM绑定需要的按钮权限标识
        const { value: requiredPerms } = binding;
        if (requiredPerms) {
            if (!hasAuth(requiredPerms)) {
                el.parentNode && el.parentNode.removeChild(el);
            }
        } else {
            throw new Error(
                "你没有权限"
            );
        }
    },
};

// 是否有权限
function hasAuth(
    value: string | string[],
    type: "button" | "role" = "button"//约束type只能为button或role,同时赋值默认值button
) {
    //获取账号下的角色和权限
    const userStore = useUserStore();
    const { roles, perms } = userStore.users;
    //「终极管理员」拥有所有的按钮权限
    if (type === "button" && roles.includes("终极管理员")) {
        return true;
    }
    //判断是否获取的是按钮权限，否则获取角色权限
    const auths = type === "button" ? perms : roles;
    //判断用户value是一堆角色还是单个角色
    return typeof value === "string"
        ? auths.includes(value)//判断用户是否有这个权限
        : auths.some((perm) => {
            return value.includes(perm);//查询需要的权限是否拥有，可能是一个按钮可以有好几个角色访问
        });
}

//Main中注册
//注册全局自定义指令
app.directive("hasPerm", hasPerm);
