Angular 6 | Express：在 dist 文件上出现 404 错误

Question

感谢您花时间阅读我的问题。当我运行 ng 服务时，我的网站工作正常。当我运行 ng build --prod 时，它也能正常工作。问题是，当我尝试在 dist 中呈现 index.html 时出现 404 错误。这些错误是我的主文件、样式文件和 polyfill 文件的 404 错误。我正在尝试建立一个后端以便我可以处理卡支付。任何帮助将不胜感激 - 几个小时以来一直没有解决我的头撞墙。这是我的代码：

server.js

var express = require('express');
var app = express();
var server = require('http').Server(app);
var bodyParser = require('body-parser');

app.use(express.static(__dirname));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));

server.listen(2000, function(){
    console.log('Listening on 2000..')
});
console.log(__dirname);


app.get('/', (req, res) => {
    res.sendFile(__dirname + '/dist/culture/index.html');
});

同样，简而言之，localhost 提供了 200 个代码，这意味着它连接到正确的位置。问题是连接后找不到任何文件。我究竟做错了什么？谢谢

Answer 1

您必须将这行代码：app.use(express.static(__dirname)); 更正为如下内容：app.use(express.static(path.join(__dirname, 'dist/culture'))); 如果您的 Angular 应用程序文件位于 dist/culture 目录中。

主要问题是，当您的 index.html 尝试加载 <link rel="icon" type="image/x-icon" href="favicon.ico"> 时，它使用对路径 http://localhost:2000/favicon.ico 的请求。您的 express 后端在 __dirname 上定义了静态资产，而您的实际应用程序在 dist/culture 中，因此您的请求应该类似于 http://localhost:2000/dist/culture/favicon.ico.

应用的更改改进了静态文件位置的配置。
