问题描述

我有一个简单的快递服务器,看起来像这样:

I have simple express server which looks like that:

Epxress应用程序:

var express = require('express');
var compression = require('compression');
var path = require('path');
var cors = require('cors');
var router = express.Router();

var app = express();

app.use('/bundle', express.static(path.join(__dirname, '/bundle')));

app.enable('trust proxy');

app.use(compression());

app.get('*', function(req, res) {
    res.header('Cache-Control', "max-age=60, must-revalidate, private");
    res.sendFile( path.join(__dirname, 'index.html') );
});


var server = app.listen(process.env.PORT || 5000, function () {
    var host = server.address().address;
    var port = server.address().port;
    console.log(`Example app listening at http://%s:%s`, host, port);
});

简单的 html文件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>React Router test</title>
</head>
<body>
    <div id="root"></div>
    <script src="bundle.js"></script>
</body>
</html>

在bundle.js里面,我有带有客户端路由的ReactJS应用程序:

Inside of bundle.js i have ReactJS application with client-side routing:

render((
    <Router history={browserHistory}>
        <Route path="/" component={App}>
            <Route path="about" component={About} />
            <Route path="about2" component={About2} />
            <Route path="about3" component={About3} />
            <Route path="*" component={NoMatch} />
        </Route>
        <Route path="*" component={NoMatch} />
    </Router>
), document.getElementById('root'));

每当我尝试导航到 domain:port/(路由器支持此路由)时,一切正常. 但是,当我尝试导航到更复杂的URL(例如 domain:port///..等)时,浏览器出现错误:

Whenever i try to navigate to domain:port/ (this route is supported by router) everething is OK. But when i try to navigate to more complex URL, like domain:port///.. etc i got an error in browser:

bundle.js:1 Uncaught SyntaxError: Unexpected token <

看起来像不是从带有index.html的静态服务器响应中发送bundle.js,在bundle.js里面有html标记.

looke like instead of send bundle.js from static server response with index.html and inside bundle.js there is html markup.

我该如何解决?

谢谢!

推荐答案

似乎正在发生环回,因为*规则每次都为index.html提供服务,而当未找到bundle.js时,它将将会投放index.html,从而尝试将<解析为javascript.

There seems to be a loopback occuring, since the * rule is serving a index.html every time, and when bundle.js is not found, it will serve index.html instead, thus trying to parse < as javascript.

一种索引接收,如果您愿意...

A sort of index-ception if you will...
