node.js - 无法从 Node 服务器打开 Angular 构建应用程序

Question

我在 Angular 6 上构建了一个应用程序，并且能够直接从 dist 文件夹打开 index.html，但是当我尝试从我的 Node 服务器打开它时，控制台中出现错误:

Uncaught SyntaxError: Unexpected token <
polyfills.js:1 Uncaught SyntaxError: Unexpected token <
styles.js:1 Uncaught SyntaxError: Unexpected token <
vendor.js:1 Uncaught SyntaxError: Unexpected token <
main.js:1 Uncaught SyntaxError: Unexpected token <

第 1 行为 <!文档类型 html >

服务器.js

const express = require('express');
const path = require('path');
const app = express();
app.use(express.static(path.join(__dirname,'dist')));
app.get('*',(req,res)=>{
    res.sendFile(path.join(__dirname,'dist/ang-node/index.html'));
});

const port = process.env.PORT || 4000;

app.listen(port,(req,res)=>{
    console.log(`server started on port ${port} `);
});

Answer 1

由于您的错误，您可能没有为 Angular 配置正确的公共(public)目录，请尝试此操作，

const express = require('express');
const path = require('path');
const app = express();
app.use(express.static(path.join(__dirname,'dist/ang-node/public'))); // <== correct public directory here
app.get('*',(req,res)=>{
    res.sendFile(path.join(__dirname,'dist/ang-node/index.html')); // <== Make sure this is dist/ang-node not dist
});

const port = process.env.PORT || 4000;

app.listen(port,(req,res)=>{
    console.log(`server started on port ${port} `);
});
