对于Vue 3，更改如下:

const router = createRouter({
    history: createWebHashHistory(),
    routes,
});

对此:

const router = createRouter({
    history: createWebHistory(),
    routes,
});

在Vue 3中，你需要使用createWebHistory作为历史选项。

import { createRouter, createWebHashHistory } from 'vue-router'

const router = createRouter({
  history: createWebHashHistory(),
  // ...
})

在Vue 2中，你需要将模式设置为“历史”。

const router = new VueRouter({
  mode: 'history',
  // ...
})

但是，请确保您的服务器配置为处理这些链接。 https://router.vuejs.org/guide/essentials/history-mode.html

对于vue.js 2，使用以下方法:

const router = new VueRouter({
 mode: 'history'
})

window.router = new VueRouter({
   hashbang: false,
   //abstract: true,
  history: true,
    mode: 'html5',
  linkActiveClass: 'active',
  transitionOnLoad: true,
  root: '/'
});

服务器配置正确 在apache你应该写url重写

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.html$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.html [L]
 </IfModule>

打开src->router->index.js文件

在这个文件的底部:

const router = new VueRouter({
  mode: "history",
  routes,
});

引用文档。

vue-router的默认模式是哈希模式-它使用URL哈希来 模拟一个完整的URL，这样页面将不会被重新加载的URL 的变化。 为了摆脱散列，我们可以使用路由器的历史模式 利用历史。pushState API实现URL导航 页面重载:

const router = new VueRouter({
  mode: 'history',
  routes: [...]
})

When using history mode, the URL will look "normal," e.g. http://oursite.com/user/id. Beautiful! Here comes a problem, though: Since our app is a single page client side app, without a proper server configuration, the users will get a 404 error if they access http://oursite.com/user/id directly in their browser. Now that's ugly. Not to worry: To fix the issue, all you need to do is add a simple catch-all fallback route to your server. If the URL doesn't match any static assets, it should serve the same index.html page that your app lives in. Beautiful, again!
