Project initialization

Project structure
vue-cil After initializing the project with the scaffolding, I only modified the src folder
src ├── App.vue ---- 页面入口 ├── api ---- api请求 │ └── login.js ---- 模拟json对象数据 ├── assets ---- 主题 字体等静态资源 │ └── logo.png ├── components ---- 组件 │ ├── index.vue │ └── login.vue ├── main.js ---- 初始化组件 加载路由 ├── router ---- 路由 │ └── index.js └── store ---- vuex状态管理 ├── getters.js ├── index.js └── modules └── login.js
Key points:
The key to dynamic routing is the coexistence of the meta field configured by the router and the status of vuex (if you don’t understand, you can check the official documentation first)
router/index .js
// 初始化路由
export default new Router({
routes: [
{
path: '/login',
name: 'Login',
component: Login
}
]
});
// 动态路由 meta 定义了role
export const powerRouter =[
{ path: '/',redirect:'/red', name: 'index',component: Index,hidden:false,
children: [
{ path: '/red', name: 'red', component: red,},
{ path: '/yellow', name: 'yellow', component: yellow, meta: {role: 'B'}},
{ path: '/blue', name: 'blue', component: blue, meta: {role: 'C'}}
]
}
];store/modules/lo
Logins({ commit }, info){
return new Promise((resolve, reject) => {
let data={};
loginByUserInfo.map(function (item) { //获取所以用户信息
if(info.username === item.username || info.pew === item.pew){
commit('SET_USERNAME',item.username); //将username和role进行存储
sessionStorage.setItem('USERNAME', item.username); //存入 session
commit('SET_ROLE',item.role);
sessionStorage.setItem('ROLE', item.role);
return data={username:item.username,introduce:item.introduce};
}else{
return data;
}
});
resolve(data);
}).catch(error => {
reject(error);
});
},
Roles({ commit }, newrouter){
return new Promise((resolve, reject) => {
commit('SET_NEWROUER',newrouter); //存储最新路由
resolve(newrouter);
}).catch(error => {
reject(error);
});
},gin.js actions part
Logins({ commit }, info){
return new Promise((resolve, reject) => {
let data={};
loginByUserInfo.map(function (item) { //获取所以用户信息
if(info.username === item.username || info.pew === item.pew){
commit('SET_USERNAME',item.username); //将username和role进行存储
sessionStorage.setItem('USERNAME', item.username); //存入 session
commit('SET_ROLE',item.role);
sessionStorage.setItem('ROLE', item.role);
return data={username:item.username,introduce:item.introduce};
}else{
return data;
}
});
resolve(data);
}).catch(error => {
reject(error);
});
},
Roles({ commit }, newrouter){
return new Promise((resolve, reject) => {
commit('SET_NEWROUER',newrouter); //存储最新路由
resolve(newrouter);
}).catch(error => {
reject(error);
});
},main.js
router.beforeEach((to, from, next) => {
if(store.getters.role){ //判断role 是否存在
if(store.getters.newrouter.length !== 0){
next() //resolve 钩子
}else{
let newrouter
if (store.getters.role == 'A') { //判断权限
newrouter = powerRouter
} else {
let newchildren = powerRouter[0].children.filter(route => {
if(route.meta){
if(route.meta.role == store.getters.role){
return true
}
return false
}else{
return true
}
});
newrouter = powerRouter
newrouter[0].children = newchildren
}
router.addRoutes(newrouter) //添加动态路由
store.dispatch('Roles',newrouter).then(res => {
next({ ...to })
}).catch(() => {
})
}
}else{
if (['/login'].indexOf(to.path) !== -1) {
next()
} else {
next('/login')
}
}
})components/index.vue
// mapGetters 辅助函数仅仅是将 store 中的 getter 映射到局部计算属性 ...mapGetters([ 'newrouter' ])
