mac制作ssl证书|生成自签名证书，nodejs+express在mac上搭建https+wss(websocket)服务器

news2025/4/16 18:14:18

注意

mac 自带 openssl 所以没必要像 windows 一样先安装 openssl，直接生成即可

生成 ssl/自签名证书

生成 key

# 生成rsa私钥，des3算法，server_ssl.key是秘钥文件名 1024位强度
openssl genrsa -des3 -out server_ssl.key 1024

让输入两次密码，随便，但是两次得是一样的

移除密码

# 这里执行完上一步的密码即已经被移除了
openssl rsa -in server_ssl.key -out server_ssl.key

生成 csr

# -new 执行生成新的证书请求
# -key 指定密钥
openssl req -new -key server_ssl.key -out server_ssl.csr

Country Name (2 letter code) [国家]:CN
State or Province Name (full name) [省份]:Beijing
Locality Name (eg, city) [城市]:Beijing
Organization Name (eg, company) [组织/公司]:zgp
Organizational Unit Name (eg, section) [部门/单位]:zgp
Common Name (eg, fully qualified host name) [域名]:test.zgp.cn
Email Address [邮箱]:demo@outlook.com
Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password [上一步已经移除，直接回车即可]:

生成证书

# x509 根据现有的证书请求生成自签名根证书
# -days 设置证书的有效天数
# -in 指定输入证书请求文件
openssl x509 -req -days 365 -in server_ssl.csr -signkey server_ssl.key -out server_ssl.crt

执行过程截图

在这里插入图片描述

创建 nodejs 的 https/wss 服务

创建 express 项目就不多说了，自行查看：nodejs+express自动生成项目
express 文档地址https://www.expressjs.com.cn/starter/generator.html

修改的 bin/www 文件

#!/usr/bin/env node

/**
 * Module dependencies.
 */

var app = require('../app');
var debug = require('debug')('express-io:server');
const fs = require('fs');
const path = require('path');
// var http = require('http');
var https = require('https');
// 引入 socket.io
const { Server } = require('socket.io')
/**
 * Get port from environment and store in Express.
 */

var port = normalizePort(process.env.PORT || '3001');
app.set('port', port);

/**
 * Create HTTPS server.
 * 加上 ssl 证书
 */
const httpsOption = {
  key: fs.readFileSync(path.resolve(__dirname, "../certificate/server_ssl.key")),
  cert: fs.readFileSync(path.resolve(__dirname, "../certificate/server_ssl.crt"))
}
var server = https.createServer(httpsOption, app);
// 创建 websocket 服务器代码
const io = new Server(server, {
        cors: {
            origin: "*"
        }
    });
    // 客户端连接成功会输出连接 id 以及 客户端传惨 query
    io.on('connection', (socket)=>{
        console.log(socket.id)
        console.log(socket.handshake.query)
    })
/**
 * Listen on provided port, on all network interfaces.
 */

server.listen(port, () => {
  console.log(`server listening on port: ${port}`)
});
server.on('error', onError);
server.on('listening', onListening);

/**
 * Normalize a port into a number, string, or false.
 */

function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}

/**
 * Event listener for HTTP server "error" event.
 */

function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }

  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;

  // handle specific listen errors with friendly messages
  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
}

/**
 * Event listener for HTTP server "listening" event.
 */

function onListening() {
  var addr = server.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
}

创建个客户端测试
