我一直在尝试用我正在做的一个node.js项目来设置HTTPS。我基本上遵循了这个例子的node.js文档:
// curl -k https://localhost:8000/
var https = require('https');
var fs = require('fs');
var options = {
key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};
https.createServer(options, function (req, res) {
res.writeHead(200);
res.end("hello world\n");
}).listen(8000);
现在，当我做的时候
curl -k https://localhost:8000/
我得到
hello world
像预期的那样。但如果我这样做了
curl -k http://localhost:8000/
我得到
curl: (52) Empty reply from server
回想起来，这似乎是显而易见的，它将以这种方式工作，但与此同时，最终访问我的项目的人不会输入https://yadayada，我希望所有的流量从他们访问网站的那一刻起就使用https。
我怎么能得到节点(和Express，因为这是我正在使用的框架)把所有传入的流量交给https，不管它是否被指定?我还没有找到任何解决这个问题的文档。或者只是假设在生产环境中，节点在它前面有一些东西(例如nginx)来处理这种重定向?
这是我第一次尝试web开发，所以如果这是显而易见的，请原谅我的无知。
我使用Basarat提出的解决方案，但我还需要覆盖端口，因为我曾经有2个不同的端口用于HTTP和HTTPS协议。
res.writeHead(301, { "Location": "https://" + req.headers['host'].replace(http_port,https_port) + req.url });
我也喜欢使用非标准端口，这样就可以在没有root权限的情况下启动nodejs。
我喜欢8080和8443，因为我在tomcat上编程了很多年。
我的完整文件变成
var fs = require('fs');
var http = require('http');
var http_port = process.env.PORT || 8080;
var app = require('express')();
// HTTPS definitions
var https = require('https');
var https_port = process.env.PORT_HTTPS || 8443;
var options = {
key : fs.readFileSync('server.key'),
cert : fs.readFileSync('server.crt')
};
app.get('/', function (req, res) {
res.send('Hello World!');
});
https.createServer(options, app).listen(https_port, function () {
console.log('Magic happens on port ' + https_port);
});
// Redirect from http port to https
http.createServer(function (req, res) {
res.writeHead(301, { "Location": "https://" + req.headers['host'].replace(http_port,https_port) + req.url });
console.log("http request, will go to >> ");
console.log("https://" + req.headers['host'].replace(http_port,https_port) + req.url );
res.end();
}).listen(http_port);
然后我使用iptable在我的HTTP和HTTPS端口上forword80和443流量。
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8443
经过多年研究从http到https的完美重定向，我在这里找到了完美的解决方案。
const http = require("http");
const https = require("https");
const { parse } = require("url");
const next = require("next");
const fs = require("fs");
const ports = {
http: 3000,
https: 3001
}
const dev = process.env.NODE_ENV !== "production";
const app = next({ dev });
const handle = app.getRequestHandler();
const httpsOptions = {
key: fs.readFileSync("resources/certificates/localhost-key.pem"),
cert: fs.readFileSync("resources/certificates/localhost.pem")
};
// Automatic HTTPS connection/redirect with node.js/express
// source: https://stackoverflow.com/questions/7450940/automatic-https-
connection-redirect-with-node-js-express
app.prepare().then(() => {
// Redirect from http port to https
http.createServer(function (req, res) {
res.writeHead(301, { "Location": "https://" + req.headers['host'].replace(ports.http, ports.https) + req.url });
console.log("http request, will go to >> ");
console.log("https://" + req.headers['host'].replace(ports.http, ports.https) + req.url);
res.end();
}).listen(ports.http, (err) => {
if (err) throw err;
console.log("ready - started server on url: http://localhost:" + ports.http);
});
https.createServer(httpsOptions, (req, res) => {
const parsedUrl = parse(req.url, true);
handle(req, res, parsedUrl);
}).listen(ports.https, (err) => {
if (err) throw err;
console.log("ready - started server on url: https://localhost:" + ports.https);
});
});
如果你遵循传统端口，因为HTTP默认尝试端口80,HTTPS默认尝试端口443，你可以简单地在同一台机器上有两个服务器:
代码如下:
var https = require('https');
var fs = require('fs');
var options = {
key: fs.readFileSync('./key.pem'),
cert: fs.readFileSync('./cert.pem')
};
https.createServer(options, function (req, res) {
res.end('secure!');
}).listen(443);
// Redirect from http port 80 to https
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(301, { "Location": "https://" + req.headers['host'] + req.url });
res.end();
}).listen(80);
使用https测试:
$ curl https://127.0.0.1 -k
secure!
与http:
$ curl http://127.0.0.1 -i
HTTP/1.1 301 Moved Permanently
Location: https://127.0.0.1/
Date: Sun, 01 Jun 2014 06:15:16 GMT
Connection: keep-alive
Transfer-Encoding: chunked
