原来的代码

const path = navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i) ? 'mobile/' : 'pc/'
console.log(path)
export const routes=[
    {
        name: "index",
        path: "/",
        component: ()=>import(`../views/BlogGather/IndexPage/${path}IndexPage.vue`),
        meta: {title: "博客"},
    },
    {
        name: "xq",
        path: "/DetailsArticlePage",
        component: import(`../views/BlogGather/DetailsArticlePage/${path}DetailsArticlePage.vue`),
        meta: {title: "详情页面"},
    },
];

这样的写法在Vue2中是可以正常运行的但是在Vue3中就不可以了的。

修改后的代码

const path = navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i) ? 'mobile/' : 'pc/'
console.log(path)
let modules = import.meta.glob('../views/BlogGather/**/**/*.vue')
console.log(modules)
export const routes=[
    {
        name: "index",
        path: "/",
        component: ()=>import(`../views/BlogGather/IndexPage/${path}IndexPage.vue`),
        meta: {title: "博客"},
    },
    {
        name: "xq",
        path: "/DetailsArticlePage",
        component: modules[(`../views/BlogGather/DetailsArticlePage/${path}DetailsArticlePage.vue`)],
        meta: {title: "详情页面"},
    },
];

我们注意到,我们是先将所有的vue文件读取出来放到一个数组之中的。

然后再去数组中取值,这样才能动态的加载组件实现动态路由的效果。
