无法访问我的站点中的链接(复制和粘贴):Node.js - Express.js - Webpack - Vue.js - historymode [英] Unable to acess links (copying and pasting) whitin my Site : Node.js - Express.js - Webpack - Vue.js - historymode

问题描述

我最近创建了一个基于 Node.js、Express.js 和 Vue.js 的网站，并在历史模式下使用路由器和 Webpack.由于是单页应用程序，我安装了 express-history-api-fallback 并且到目前为止它工作得很好但是(一如既往地有但是)由于某些原因我不理解某些网址，我得到了一个白页以及一些错误，例如:

I recently created a website with base on Node.js, Express.js and Vue.js with router in history mode and Webpack. Since is a Single Page Application, I installed express-history-api-fallback and it works quite fine so far but (as always there is a but) for some reasons that I'm not understanding for some urls, i get a white page and some errors like:

Uncaught SyntaxError: Unexpected token '<'          ------        manifest.61d5cd8248647cdb144a.js:1
Uncaught SyntaxError: Unexpected token '<'          ------        vendor.db7271094dc9fcde8b9f.js:1
Uncaught SyntaxError: Unexpected token '<'          ------        app.3cfe27cef1608de00b06.js:1 

我不明白问题是在我的 webpack conf 文件中还是在我的 node.js 中(我猜与前端有关，因为我没有看到任何传入的请求)或我的 vue-路由器.

I don't understand whether the problem is within my webpack conf file or withing my node.js (I guess is related to the front-end cause I'm not seeing any incoming request in the be) or in my vue-router.

我不明白的原因(除了缺乏知识)是，如果我尝试访问我的 Vue 应用程序中的页面，单击链接(即访问格式为 mywebsiteinexample.com 的用户个人资料页面)/user/userId) 它可以工作，但如果我刷新页面，我只能看到一个白页，并且在控制台内，我会看到上面写的错误.

The reason why I don't understand (apart of lack of knowledge) is that if I try to access to a page within my Vue app, clicking on a link (i.e. accessing to an user's profile page formatted as mywebsiteinexample.com/user/userId) it works but if i refresh the page I'm just able to see a white page and, inside the console, the errors I wrote about above.

我的文件的一般架构:

我想这里有一些有用的代码:

here are some, I guess, useful peaces of code:

Server.js

const express = require('express')
const fallback = require('express-history-api-fallback')
const path = require('path')

const historyModeHandlerHTTP = express()
const root = `${__dirname}/../`
historyModeHandlerHTTP.use(express.static(root))
historyModeHandlerHTTP.use(fallback(path.join(__dirname + '/../index.html')))

historyModeHandlerHTTP.listen(80, () => {
    console.log('HTTP Server on')
})

推荐答案

[SOLUTION]

问题与Webpack的配置有关！如果有人遇到同样的问题，只需设置 PublicPath : '/'

The Problem was related to the configuration of Webpack! If anyone is facing the same problem, just set the PublicPath : '/'

  output: {
    publicPath: '/',
    path: config.build.assetsRootMain,
    filename: utils.assetsPath('js/[name].[chunkhash].js'),
    chunkFilename: utils.assetsPath('js/[id].[chunkhash].js')
  },
