很多时候我们在项目的路由都是在前端配置好的
但是有的时候为了进行全面的权限控制,会需要后台给出路由表,前端再渲染。不用在前端配置。下面主要讲一下思路
1、和后台小哥哥沟通好数据,把我们前端配置的路由表数据给他,他就能看懂了2、拿到数据需要我们自己再处理

路由中的component后台是给不了的,这里我们只需要后台小哥哥按照我们提供的前端component路径给数据,我们循环加载就可以了
//view就是后台给的数据
return () => import(`@/view/modules/${view}`);
//view就是后台给的数据
return () => import(`@/view/modules/${view}`);这样我们就拿到了最重要的数据,即component。3、把后台提供的数据处理成我们需要的路由表
4、添加到路由中
Router.addRoutes(路由数据)
Router.addRoutes(路由数据)以下讲一下我在项目中实现过程1、新建一个router.js1、新建一个router.js里面做些基本的路由操作,比如导入包,因为我们拿到数据之后还是要自己手动去放到路由中去的
也会写一写不需要后台提供的菜单数据,比如我们测试页面或者login等等
import Vue from "vue";
import Router from "vue-router";
import AppMain from "@/view/modules/main/index";
Vue.use(Router);
export const _CONSTANTS_ROUTERS =
[

{

path: "/login",

component: () => import("@/view/modules/login/index"),

hidden: true

},

{

path: "",

component: AppMain,

redirect: "/dashboard",

children: [

{

path: "/dashboard",

component: () => import("@/view/modules/dashboard/index"),

name: "Dashboard",

meta: { title: "首页", icon: "dashboard", noCache: true }

}

]

}
];
export default new Router({

mode: "history",

// 解决vue框架页面跳转有白色不可追踪色块的bug

scrollBehavior: () => ({ x: 0, y: 0 }),

// scrollBehavior: () => ({ y: 0 }),

routes: _CONSTANTS_ROUTERS
});
import Vue from "vue";
import Router from "vue-router";
import AppMain from "@/view/modules/main/index";
Vue.use(Router);
export const _CONSTANTS_ROUTERS =
[

{

path: "/login",

component: () => import("@/view/modules/login/index"),

hidden: true

},

{

path: "",

component: AppMain,

redirect: "/dashboard",

children: [

{

path: "/dashboard",

component: () => import("@/view/modules/dashboard/index"),

name: "Dashboard",

meta: { title: "首页", icon: "dashboard", noCache: true }

}

]

}
];
export default new Router({

mode: "history",

// 解决vue框架页面跳转有白色不可追踪色块的bug

scrollBehavior: () => ({ x: 0, y: 0 }),

// scrollBehavior: () => ({ y: 0 }),

routes: _CONSTANTS_ROUTERS
});基本路由表已经建立好了2、我们在什么时候进行获取完整的路由表数据2、我们在什么时候进行获取完整的路由表数据这个时候我们就要想到路由钩子函数,当然是Router.beforeEach中做
Router.beforeEach((to, from, next) =>
{

NProgress.start();

if (!Token.isEmpty())

{

if (to.path === "/login")

{

next({ path: "/" });

NProgress.done();

}

else if (to.path === "/404")

{

next();

NProgress.done();

}

else

{

// 判断当前用户是否已拉取完角色信息

if (Store.getters.roles.length === 0)

{

//拉取路由数据
ACLRepo.listMenuTreeOfCurrentUser().then(response =>

{

Store.dispatch("generateRoutes", response).then(() =>

{

// 根据roles权限生成可访问的路由表

Router.addRoutes(Store.getters.addRouters); // 动态添加可访问路由表

next({ ...to, replace: true }); // hack方法 确保addRoutes已完成 ,set the replace: true so the navigation will not leave a history record

});

});

}

else

{

next();

}

}

}

else

{

next();

}
});
Router.beforeEach((to, from, next) =>
{

NProgress.start();

if (!Token.isEmpty())

{

if (to.path === "/login")

{

next({ path: "/" });

NProgress.done();

}

else if (to.path === "/404")

{

next();

NProgress.done();

}

else

{

// 判断当前用户是否已拉取完角色信息

if (Store.getters.roles.length === 0)

{

//拉取路由数据
ACLRepo.listMenuTreeOfCurrentUser().then(response =>

{

Store.dispatch("generateRoutes", response).then(() =>

{

// 根据roles权限生成可访问的路由表

Router.addRoutes(Store.getters.addRouters); // 动态添加可访问路由表

next({ ...to, replace: true }); // hack方法 确保addRoutes已完成 ,set the replace: true so the navigation will not leave a history record

});

});

}

else

{

next();

}

}

}

else

{

next();

}
});3、路由数据重新封装3、路由数据重新封装generateRoutes
import { _CONSTANTS_ROUTERS } from "@/scripts/router";
import AppMain from "@/view/modules/main/index";
const _PERMISSION = {

state: {

routers: _CONSTANTS_ROUTERS,

addRouters: []

},

mutations: {

setRouters: (state, routers) =>

{

state.addRouters = routers;

//和已经存在的路由表拼接

state.routers = _CONSTANTS_ROUTERS.concat(routers);

}

},

actions: {

generateRoutes({ commit }, response)

{

let asyncRouters = filterAsyncRouter(response);

asyncRouters.push({ path: "*", redirect: "/404", hidden: true });

commit("setRouters", asyncRouters);

}

}
};

function filterAsyncRouter(routers)
{

// 遍历后台传来的路由字符串,转换为组件对象

let accessedRouters = routers.filter(router =>

{

if (router.meta)

{

// 默认图标处理

router.meta.icon = router.meta.icon ? router.meta.icon : "component";

}

if (router.component === "main")

{

// Main组件特殊处理

router.component = AppMain;

}

else

{

//处理组件---重点

router.component = loadView(router.component);

}

//存在子集

if (router.children && router.children.length)

{

router.children = filterAsyncRouter(router.children);

}

return true;

});

return accessedRouters;
}
function loadView(view)
{

// 路由懒加载

return () => import(`@/view/modules/${view}`);
}
export default _PERMISSION;
import { _CONSTANTS_ROUTERS } from "@/scripts/router";
import AppMain from "@/view/modules/main/index";
const _PERMISSION = {

state: {

routers: _CONSTANTS_ROUTERS,

addRouters: []

},

mutations: {

setRouters: (state, routers) =>

{

state.addRouters = routers;

//和已经存在的路由表拼接

state.routers = _CONSTANTS_ROUTERS.concat(routers);

}

},

actions: {

generateRoutes({ commit }, response)

{

let asyncRouters = filterAsyncRouter(response);

asyncRouters.push({ path: "*", redirect: "/404", hidden: true });

commit("setRouters", asyncRouters);

}

}
};

function filterAsyncRouter(routers)
{

// 遍历后台传来的路由字符串,转换为组件对象

let accessedRouters = routers.filter(router =>

{

if (router.meta)

{

// 默认图标处理

router.meta.icon = router.meta.icon ? router.meta.icon : "component";

}

if (router.component === "main")

{

// Main组件特殊处理

router.component = AppMain;

}

else

{

//处理组件---重点

router.component = loadView(router.component);

}

//存在子集

if (router.children && router.children.length)

{

router.children = filterAsyncRouter(router.children);

}

return true;

});

return accessedRouters;
}
function loadView(view)
{

// 路由懒加载

return () => import(`@/view/modules/${view}`);
}
