角 6 | Express : 在 dist 文件上出现 404 错误

Dre*_*son 4 node.js express angular angular6

感谢您花时间阅读我的问题。当我运行 ng serve 时，我的网站运行良好。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，我收到 404 错误。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，以便我可以处理卡付款。任何帮助将不胜感激 - 已经把我的头撞在墙上几个小时了，没有下定决心。这是我的代码如下：

服务器.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');
});

再次，简而言之，localhost 给出了 200 代码，这很好，这意味着它连接到正确的位置。问题是一旦连接它就找不到任何文件。我究竟做错了什么？谢谢

您必须将这行代码更正app.use(express.static(__dirname));为：app.use(express.static(path.join(__dirname, 'dist/culture')));如果您的 Angular 应用程序文件在dist/culture目录中。

主要问题是，当您index.html的示例尝试加载<link rel="icon" type="image/x-icon" href="favicon.ico">它时，它使用 request to path http://localhost:2000/favicon.ico。您的express后端已经定义了静态资产__dirname并且您的实际应用程序在其中，dist/culture因此您的请求应该看起来像http://localhost:2000/dist/culture/favicon.ico.

应用更改改进了静态文件位置的配置。
