Node啓動https服務器

首先你需要生成https證書，可以去付費的網站購買或者找一些免費的網站，可能會是key或者crt或者pem結尾的。不同格式之間可以通過OpenSSL轉換，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')

// 根據項目的路徑導入生成的證書文件
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,
}

// 創建https服務器實例
const httpsServer = https.createServer(credentials, async (req, res) => {
  res.writeHead(200)
  res.end('Hello World!')
})

// 設置https的訪問端口號
const SSLPORT = 443

// 啓動服務器，監聽對應的端口
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')

// 根據項目的路徑導入生成的證書文件
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,
}

// 創建express實例
const app = express()

// 處理請求
app.get('/', async (req, res) => {
  res.status(200).send('Hello World!')
})

// 創建https服務器實例
const httpsServer = https.createServer(credentials, app)

// 設置https的訪問端口號
const SSLPORT = 443

// 啓動服務器，監聽對應的端口
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')

// 根據項目的路徑導入生成的證書文件
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,
}

// 創建koa實例
const app = koa()

// 處理請求
app.use(async ctx => {
  ctx.body = 'Hello World!'
})

// 創建https服務器實例
const httpsServer = https.createServer(credentials, app.callback())

// 設置https的訪問端口號
const SSLPORT = 443

// 啓動服務器，監聽對應的端口
httpsServer.listen(SSLPORT, () => {
  console.log(`HTTPS Server is running on: https://localhost:${SSLPORT}`)
})
