node.js SSL证书安装指南

众所周知 Node.js 可以很简单的创建一个http或https的高性能的web服务器。默认情况下，Node.js通过HTTP提供内容。但是我们还必须使用HTTPS模块才能通过安全通道与客户端进行通信。这是一个内置模块，其用法与我们使用HTTP模块的方式非常相似。

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, './ssl/server.key'), 'utf8')
const certificate = fs.readFileSync(path.join(__dirname, './ssl/server.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, './ssl/server.key'), 'utf8')
const certificate = fs.readFileSync(path.join(__dirname, './ssl/server.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, './ssl/server.key'), 'utf8')
const certificate = fs.readFileSync(path.join(__dirname, './ssl/server.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}`)
})
