我有一个快速应用程序托管一个反应网络应用程序。我正在使用HelmetJS帮助我的快速应用程序的安全。
我还将在可能的情况下返回gzipped资产。但是,由于向Express添加了头盔,所以在加载我的托管web应用程序时,我现在会遇到以下错误
Refused to execute script from 'http://localhost:3000/static/main.8bbec8980664a60606b0.min.js' because its MIME type ('application/gzip') is not executable, and strict MIME type checking is enabled.我的快递应用程序如下..。
const express = require('express');
const helmet = require('helmet');
const path = require('path');
const app = express();
const POLICY_NONE = ["'none'"];
const POLICY_SELF = ["'self'"];
app.use(helmet());
app.use(helmet.referrerPolicy({ policy: 'same-origin' }))
app.use(
helmet.contentSecurityPolicy({
directives: {
defaultSrc: POLICY_SELF,
connectSrc: POLICY_SELF,
fontSrc: POLICY_SELF,
imgSrc: POLICY_SELF,
manifestSrc: POLICY_SELF,
mediaSrc: POLICY_SELF,
objectSrc: POLICY_NONE,
scriptSrc: POLICY_SELF,
styleSrc: POLICY_SELF,
workerSrc: POLICY_SELF,
formAction: POLICY_SELF,
frameAncestors: POLICY_NONE,
blockAllMixedContent: true,
upgradeInsecureRequests: false,
}
})
);
app.use((req, res, next) => {
if (/\.(js|css)$/.test(req.url)) {
req.url = req.url + '.gz';
res.set('Content-Encoding', 'gzip');
}
next();
});
app.use(express.static(path.resolve(__dirname, '../dist')));
app.get('/healthz', (req, res) => res.send('OK'));
app.get('*', (req, res) =>
res.sendFile(path.resolve(__dirname, '../dist/index.html'))
);
const PORT = process.env.SERVER_PORT || 3000;
const HOST = process.env.SERVER_HOST || '127.0.0.1';
app.listen(PORT);
console.log(`API started on ${HOST}:${PORT}`);在dist文件夹中呈现的索引html如下所示
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<body>
<div id="root"></div>
<script type="text/javascript" src="static/main.8bbec8980664a60606b0.min.js"></script></body>
</html>如果我不戴头盔,这就很好了。如何配置头盔以允许仍然加载此文件?

您可以使用express-static-gzip包。它是一个Express中间件。它负责设置Content-Type头,以及其他事情,比如检查浏览器接受哪种编码。
示例:
var express = require("express");
var expressStaticGzip = require("express-static-gzip");
var app = express();
app.use("/", expressStaticGzip("/my/rootFolder/"));https://stackoverflow.com/questions/50376467
