+
+1.安装node环境（自行谷歌百度，不赘述） 2.安装express（自行谷歌百度，不赘述） 3.打开命令行，利用openssl生成证书文件
+
+```js
+
+//生成私钥key文件
+openssl genrsa 1024 > /keys/private.pem
+
+//通过私钥文件生成CSR证书签名
+openssl req -new -key /keys/private.pem -out /keys/csr.pem
+
+//通过私钥文件和CSR证书签名生成证书文件
+openssl x509 -req -days 365 -in /keys/csr.pem -signkey /keys/private.pem -out /keys/file.crt
+```
+
+4.编写server文件
+
+```js
+
+var app = require('express')();
+var fs = require('fs');
+var http = require('http');
+var https = require('https');
+
+//引入私钥、证书
+var privateKey  = fs.readFileSync('./keys/private.pem', 'utf8');
+var certificate = fs.readFileSync('./keys/file.crt', 'utf8');
+var credentials = {key: privateKey, cert: certificate};
+
+//创建服务，设置端口号
+var httpServer = http.createServer(app);
+var httpsServer = https.createServer(credentials, app);
+var PORT = 18080;
+var SSLPORT = 18081;
+
+//监听端口号
+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);
+});
+
+//路由
+app.get('/', function(req, res) {
+    if(req.protocol === 'https') {
+        res.status(200).send('这是一个经过加密的https请求！');
+    }
+    else {
+        res.status(200).send('这是一个普通的http请求！');
+    }
+});
+
+```
+
+5.启动服务
+
+```js
+
+node server.js
+```
