首先你需要生成https证书，可以去付费的网站购买或者找一些免费的网站，可能会是key或者crt或者pem结尾的。不同格式之间可以通过OpenSSL转换，如：

openssl x509 -in mycert.crt -out mycert.pem -outform PEM

Node原生版本:

const https = require("https")
const path = require("path")
const fs = require("fs")
// 根据项目的路径导入生成的证书文件
const privateKey = fs.readFileSync(path.join(__dirname, "./certificate/private.key"), "utf8")
const certificate = fs.readFileSync(path.join(__dirname, "./certificate/certificate.crt"), "utf8")
const credentials = {
 key: privateKey,
 cert: certificate,
}
// 创建https服务器实例
const httpsServer = https.createServer(credentials, async (req, res) => {
 res.writeHead(200)
 res.end("Hello World!")
})
// 设置https的访问端口号
const SSLPORT = 443
// 启动服务器，监听对应的端口
httpsServer.listen(SSLPORT, () => {
 console.log(`HTTPS Server is running on: https://localhost:${SSLPORT}`)
})

express版本

const express = require("express")
const path = require("path")
const fs = require("fs")
const https = require("https")
// 根据项目的路径导入生成的证书文件
const privateKey = fs.readFileSync(path.join(__dirname, "./certificate/private.key"), "utf8")
const certificate = fs.readFileSync(path.join(__dirname, "./certificate/certificate.crt"), "utf8")
const credentials = {
 key: privateKey,
 cert: certificate,
}
// 创建express实例
const app = express()
// 处理请求
app.get("/", async (req, res) => {
 res.status(200).send("Hello World!")
})
// 创建https服务器实例
const httpsServer = https.createServer(credentials, app)
// 设置https的访问端口号
const SSLPORT = 443
// 启动服务器，监听对应的端口
httpsServer.listen(SSLPORT, () => {
 console.log(`HTTPS Server is running on: https://localhost:${SSLPORT}`)
})

koa版本

const koa = require("koa")
const path = require("path")
const fs = require("fs")
const https = require("https")
// 根据项目的路径导入生成的证书文件
const privateKey = fs.readFileSync(path.join(__dirname, "./certificate/private.key"), "utf8")
const certificate = fs.readFileSync(path.join(__dirname, "./certificate/certificate.crt"), "utf8")
const credentials = {
 key: privateKey,
 cert: certificate,
}
// 创建koa实例
const app = koa()
// 处理请求
app.use(async ctx => {
 ctx.body = "Hello World!"
})
// 创建https服务器实例
const httpsServer = https.createServer(credentials, app.callback())
// 设置https的访问端口号
const SSLPORT = 443
// 启动服务器，监听对应的端口
httpsServer.listen(SSLPORT, () => {
 console.log(`HTTPS Server is running on: https://localhost:${SSLPORT}`)
})
