Node如何启动https服务器

这次给大家带来Node如何启动https服务器，Node启动https服务器的注意事项有哪些，下面就是实战案例，一起来看一下。

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}`)
})
