vue中的 mode:history 与路由的router.beforeEach钩子能共存吗？

阅读更多关于 vue中的 mode:history 与路由的router.beforeEach钩子能共存吗？

今天遇到一个问题,在路由定义的js中使用mode:history import Vue from 'vue' import Router from 'vue-router' import login from '@/components/login' import index from '@/views/index' Vue . use ( Router ) export default new Router ({ mode: 'history' , routes: [ { path: '/login' , name: 'login' , component: login }, { path: '/index' , name: 'index' , component: index } ] }) 然后再main.js中使用路由的生命钩子进行登录控制 router . beforeEach (( to , from , next ) => { if ( to . path != '/login' ) { next ({ path: '/login' }) } else { next () } }) 但是在页面使用时,我访问index对应的页面却没有跳转login。如果去掉mode:history 重启项目后就可以使用了这是不是因为i这两者之间冲突还是我写的不对呀有没有大佬帮看下

问题 Locked . This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions. Alan Kay was quoted several years ago to the effect that there had been only three new things in software in the preceding 20 years (effectively the lifespan of PCs). One of them was Spreadsheets. Does anyone remember the other two? Who is Alan Kay? (a few may ask.) His work at Xerox Parc arguably did more to shape our

单页面应用的History路由模式express后端中间件配合

阅读更多关于单页面应用的History路由模式express后端中间件配合

这篇文章主要分享一下通过 HTML5 的 history API 的时候，使用 NodeJS 后端应该如何配置，来避免产生404的问题，这里是使用的express的框架，主要是通过 connect-history-api-fallback 这个中间件来实现的！这里使用vue-router来实现的单页应用为例，访问 http://cnode.lsqy.tech ，进入首页，点击下面的tab栏，一切都是很正常的，但当这时候你 ctrl+command+R 或点击浏览器的刷新按钮或在地址栏上再敲一下回车，总之就是刷新，发现就会出现404了，比如这样的错误 Cannot GET /message/ ,因为默认浏览器会认为你是在请求服务端的路由，服务端那边没有对应的处理，所以自然就会出错了，下面来引入 connect-history-api-fallback 这个中间件，来无痛使用优雅的History路由模式。首先看它的介绍 Middleware to proxy requests through a specified index page, useful for **Single Page Applications** that utilise the HTML5 History API. 中文意思就是一个能够代理请求返回一个指定的页面的中间件，对于单页应用中使用HTML5
