使用 git客户端msysgit , 其中已包含了 openssl 程序

# 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 certrequest.csr

# 通过私钥和证书签名生成证书文件
openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem

有了证书之后，开始创建服务

const https = require("https");
const http = require("http");
const fs = require("fs")

// 创建 http 服务
const httpServer = http.createServer((req, res) => {
    res.writeHead(200);
    res.end("this is a http server")
})
httpServer.listen(3000, function() {
    console.log("http server is running on: http://localhost:3000");
})


// 创建 https 服务
const privateKey = fs.readFileSync('./privateKey.pem')
const certificate = fs.readFileSync('./certificate.pem')
const httpsServer = https.createServer({
    key: privateKey,
    cert: certificate 
}, (req, res) => {
    res.writeHead(200);
    res.end("this is a https server")
})
httpsServer.listen(3006, function() {
    console.log("https server is running on https://localhost:3006")
})

完成，打开浏览器访问 localhost:3000, https://localhost:3006 即可。
