Vue Router - 捕获所有通配符不起作用
Vue Router - catch all wildcard not working
我将 Vue Router 与 Vue 3 一起使用,并尝试添加一个包罗万象的路由,以便在用户尝试访问无效 URL 时重定向用户。当我尝试使用通配符 (*) 时,我将以下错误记录到控制台:
Uncaught Error: A non-empty path must start with "/"
at tokenizePath (vue-router.esm.js?8c4f:975)
at createRouteRecordMatcher (vue-router.esm.js?8c4f:1106)
at addRoute (vue-router.esm.js?8c4f:1190)
at eval (vue-router.esm.js?8c4f:1335)
at Array.forEach (<anonymous>)
at createRouterMatcher (vue-router.esm.js?8c4f:1335)
at createRouter (vue-router.esm.js?8c4f:2064)
at eval (index.js?a18c:26)
at Module../src/router/index.js (app.js:1402)
at __webpack_require__ (app.js:854)
我假设这是因为我没有在包含星号的路径前加上“/”,但如果我这样做,那么 catch all 将不起作用。这是我的路线:
imports...
const routes = [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/user',
name: 'User',
// route level code-splitting
// this generates a separate chunk (user.[hash].js) for this route
// which is lazy-loaded when the route is visited.
component: () => import(/* webpackChunkName: "user" */ '../views/user/User.vue'),
children: [{path: '', component: UserStart}, {path: ':id', component: UserDetail}, {path: ':id/edit', component: UserEdit, name: 'userEdit'}]
},
{path: '/redirect-me', redirect: '/user'},
{path: '*', redirect: '/'}
]
const router = createRouter({
history: createWebHashHistory(),
routes
})
export default router
通配符路由是路由数组中的最后一个对象。有谁知道我做错了什么?
使用带有自定义正则表达式的参数捕获所有路由 (/*) must now be defined:/:catchAll(.*)
例如:
{
// path: "*",
path: "/:catchAll(.*)",
name: "NotFound",
component: PageNotFound,
meta: {
requiresAuth: false
}
}
就我个人而言,对于 Vue 3 中的 Vue 2 *(星号或捕获所有)路线,我使用:
{
path: '/:pathMatch(.*)*', <== THIS
name: 'not-found',
component: NotFound
}
现在必须使用带有自定义正则表达式的参数来定义捕获所有路由 (*, /*):
参数名可以随便起,比如catchAll, pathMatch, noPage
等等
{
path: '/:pathMatch(.*)*', //will match everything and put it under `$route.params.pathMatch`
name: 'not-found',
component: NotFound
}
{
path: '/user-:afterUser(.*)',// will match anything starting with `/user-` and put it under `$route.params.afterUser`
component: UserGeneric
}
/:pathMatch(.*)*
最后一个 *
如果您打算使用它的名称直接导航到 not-found 路线,则这是必要的。
如果省略params中的/
字符,解析或推送时会进行编码
例如,如果您使用 path: /:pathMatch(.*)
(注意:没有最后一个星号)并转到 /user/not-found
(不存在的页面),则 this.$route.params.pathMatch
将是字符串 => 'user/not-found'
// bad example if using named routes:
router.resolve({
name: 'bad-not-found',
params: { pathMatch: 'not/found' },
}).href // '/not%2Ffound'
相反,如果您使用 path: /:pathMatch(.*)*
(注意:带星号)this.$route.params.pathMatch
将是一个数组 ['user', 'not-found']
// good example:
router.resolve({
name: 'not-found',
params: { pathMatch: ['not', 'found'] },
}).href // '/not/found'
