我正在运行Express Web服务器。我使用Let's Encypt为我的域的www版本和非www版本创建SSL证书。我的DNS有以下记录:
CNAME | Host: @ | Target: dynamicdns.example.com. | TTL: 60min
CNAME | Host: www | Target: dynamicdns.example.com. | TTL: 60min
我也有以下node.js代码来运行Web服务器:
// Dependencies
const express = require('express');
const fs = require('fs');
const http = require('http');
const https = require('https');
// Create express instance
const app = express();
// Get credentials from system
const privateKey = fs.readFileSync('/etc/letsencrypt/live/www.example.com/privkey.pem', 'utf8');
const certificate = fs.readFileSync('/etc/letsencrypt/live/www.example.com/cert.pem', 'utf8');
const ca = fs.readFileSync('/etc/letsencrypt/live/www.example.com/chain.pem', 'utf8');
const credentials = {
key: privateKey,
cert: certificate,
ca: ca
};
// Initalize server
app.use(express.static('public'));
const httpServer = http.createServer(app);
const httpsServer = https.createServer(credentials, app);
// Listen for HTTP
httpServer.listen(80, () => {
console.log('HTTP Server running on port 80');
});
// Listen for HTTPS
httpsServer.listen(443, () => {
console.log('HTTPS Server running on port 443');
});
这一切都可以正常工作,但是会产生一个问题,即对于同一内容具有多个有效URL。现在,以下URL均有效:
http://example.com
http://www.example.com
https://example.com
https://www.example.com
我想将所有错误的URL重定向到https://www.example.com
,这是正确的URL。我不确定该怎么做。任何帮助将不胜感激。

您可以使用像这样的中间件来检查所有域并进行相应的重定向:
app.use((req, res, next) => {
if (!req.secure) {
return res.redirect('https://' + req.get('host') + req.url);
}
next()
})
只需确保仅将其用于生产
