一、 构建Https服务器
新建工程
$ cd /home
$ express -e ExpressServer
$ cd ExpressServer
$ sudo npm install
生成证书文件
# 创建一个文件夹存放证书
$ mkdir cert
$ cd cert
#生成私钥key文件：
$ openssl genrsa -out privatekey.pem 1024
#通过私钥生成CSR证书签名
$ openssl req -new -key privatekey.pem -out certsign.csr
# 通过私钥和证书签名生成证书文件
$ openssl x509 -req -in certsign.csr -signkey privatekey.pem -out certificate.crt
生成了三个文件：
privatekey.pem (私钥)
certsign.csr (CSR证书签名)
certificate.crt (证书文件)
Express服务端代码
var app = require('express')();
var fs = require('fs');
var http = require('http');
var https = require('https');
var httpServer = http.createServer(app);
var httpsServer = https.createServer({
key: fs.readFileSync('./cert/privatekey.pem', 'utf8'),
cert: fs.readFileSync('./cert/certificate.crt', 'utf8')
}, app);
var PORT = 8000;
var SSLPORT = 9000;
httpServer.listen(PORT, function() {
console.log('HTTP Server is running on: http://localhost:%s', PORT);
});
httpsServer.listen(SSLPORT, function() {
console.log('HTTPS Server is running on: https://localhost:%s', SSLPORT);
});
// 访问路径
app.get('/:name', function(req, res) {
if(req.protocol === 'https') {
res.send('https:' + req.params.name);
} else {
res.send('http:' + req.params.name);
}
});
