大概记录一下主要代码
1.根据后端返回的路由列表生成左侧菜单后端返回的数据结构中用id和pid来区别包含关系
大概结构如下
2.前端需要处理成包含children的树形结构
//动态生成菜单
export const generatorDynamicRouter (data) {console.log(generatorDynamicRouter, data);return new Promise((resolve, reject) {const resNav data.antDesignmenusconst menuNav []const childrenNav []// 后端数据, 根级树数组, 根级 PIDlistToTree(resNav, childrenNav, 0)/*** 增加静态网页*/listToTree(userAccount, childrenNav, 0)rootRouter.children childrenNavmenuNav.push(rootRouter)const routers generator(menuNav)routers.push(notFoundRouter)resolve(routers)}).catch(err {// reject(加载菜单失败)return Promise.reject(err)})
}/*** 数组转树形结构* param list 源数组* param tree 树* param parentId 父ID*/
const listToTree (list, tree, parentId) {list.forEach(item {// 判断是否为父级菜单// eslint-disable-next-line eqeqeqif (item.pid parentId) {const child {...item,key: item.key || item.name,children: []}// 迭代 list 找到当前菜单相符合的所有子菜单listToTree(list, child.children, item.id)// 删掉不存在 children 值的属性if (child.children.length 0) {delete child.children}// 加入到树中tree.push(child)}})
}/*** 格式化树形结构数据 生成 vue-router 层级路由表** param routerMap* param parent* returns {*}*/
export const generator (routerMap, parent) {return routerMap.map(item {// eslint-disable-next-line no-unused-varsconst { title, show, hideChildren, hiddenHeaderContent, target, icon, link } item.meta || {}const currentRouter {// 如果路由设置了 path则作为默认 path否则 路由地址 动态拼接生成如 /dashboard/workplacepath: item.path || ${parent parent.path || }/${item.key},// 路由名称建议唯一name: item.name || item.key || ,// 该路由对应页面的 组件 :方案1// component: constantRouterComponents[item.component || item.key],// 该路由对应页面的 组件 :方案2 (动态加载)component: (constantRouterComponents[item.component || item.key]) || (() import(/views/${item.component})),// meta: 页面标题, 菜单图标, 页面权限(供指令权限用可去掉)meta: {title: title,icon: icon || undefined,// hiddenHeaderContent: hiddenHeaderContent,target: target,link: link},hidden: item.hidden}// 是否设置了隐藏菜单if (show false) {currentRouter.hidden true}// 是否设置了隐藏子菜单if (hideChildren) {currentRouter.hideChildrenInMenu true}// 为了防止出现后端返回结果不规范处理有可能出现拼接出两个 反斜杠if (!currentRouter.path.startsWith(http)) {currentRouter.path currentRouter.path.replace(//, /)}// 重定向item.redirect (currentRouter.redirect item.redirect)// 是否有子菜单并递归处理if (item.children item.children.length 0) {// RecursioncurrentRouter.children generator(item.children, currentRouter)}return currentRouter})
}
3.在Vuex中存储路由
/*** 向后端请求用户的菜单动态生成路由*/
import { constantRouterMap, detailRouter } from /config/router.config
import { generatorDynamicRouter } from /router/generator-routersconst permission {state: {routers: constantRouterMap,addRouters: []},mutations: {SET_ROUTERS: (state, routers) {state.addRouters routersstate.routers constantRouterMap.concat(routers)console.log(SET_ROUTERS, routers);}},actions: {GenerateRoutes ({ commit }, data) {return new Promise(resolve {generatorDynamicRouter(data).then(routers {let _index routers.findIndex((item) item.path /)if (_index ! -1 routers[_index].children routers[_index].children.length) {// 这个是路由生成后添加的自定义详情页路由routers[_index].children routers[_index].children.concat(detailRouter)}console.log(routers, routers-----routers---routers)commit(SET_ROUTERS, routers)resolve()})}).catch(err {// eslint-disable-next-line no-undefreject(err)})}}
}export default permission
4.最后在permission.js文件中的路由守卫里动态添加路由 5.最后生成菜单路由格式
