},
{
path: '/template',
name: 'nav.Template',
meta: {
permission: [] },
component: (resolve) => require(['@/components/Template/template'], resolve)
},
{
path: '/generalSet',
name: 'nav.System',
meta: {
permission: [] },
component: (resolve) => require(['@/components/SystemSet/generalSet'], resolve)
},
{
path: '',
name: 'nav.Log',
component: App,
children: [
{
path: '/userLog',
name: 'nav.UserLog',
meta: {
permission: [] },
component: (resolve) => require(['@/components/Log/userLog'], resolve),
},
{
path: '/operatingLog',
name: 'nav.SystemLog',
meta: {
permission: [] },
component: (resolve) => require(['@/components/Log/operatingLog'], resolve),
},
] }
]];
为每个路由页面增加meta字段。在routerMatch函数中将匹配到的详细权限字段赋值到这里。这样在每个页面的route对象中就会得到这个字段。
asyncRouter.find((s) => {
if (s.path === '') {
s.children.find((y) => {
if (y.path === path) {
//赋值
y.meta.permission = item.permission;
routers.push(s);
}
})
}
if (s.path === path) {
s.meta.permission = item.permission;
routers.push(s);
}
})接下来我们编写一个vue自定义指令对页面中需要进行鉴权的元素进行判断，比如类似这样的：
<a @click="upload" v-allow="'3'"></a> /* 3代表一个上传权限的ID，权限中有3则显示按钮 */我们直接注册一个全局指令，利用vnode来访问vue的方法。代码如下：
//main.js
//按扭权限指令
Vue.directive('allow', {
inserted: (el, binding, vnode) => {
let permissionList = vnode.context.$route.meta.permission;
if (!permissionList.includes(binding.value)) {
el.parentNode.removeChild(el)
}
}
})至此为止，权限控制流程就已经完全结束了，在最后我们再看一下完整的权限控制流程图吧.
