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'
