• 生成SSL证书

openssl genrsa -out privkey.pem 1023openssl req -new -key privkey.pem -out certreq.csropenssl x509 -req -days 3650 -in certreq.csr -signkey privkey.pem -out newcert.pem

• 基本服务器

var fs = require('fs');var https = require('https');var express = require('express');var app = express();var options = {  key: fs.readFileSync('privkey.pem').toString(),  cert: fs.readFileSync('newcert.pem').toString()};https.createServer(options, app).listen(8080);app.get('*', function (req, res) {  res.end('START HTTPS');});

• 不同平台的文件路径连接符号

var path = require('path');path.sep;

• 判断平台

process.platform //darwin, win32

• 运行node脚本

//hello#!/usr/bin/env node     // 正常情况下可以改成#!usr/local/bin/nodeconsole.log('hello');//权限chmod 755 hello        //0755 = User:rwx Group:r-x World:r-x//运行./hello

• 输入输出流

//sdin, stdout, stderr//将输入字符串md5加密后输出var crypto = require('crypto');process.stdout.write('> ');process.stdin.setEncoding('utf8');process.stdin.on('data', function (data) {  if(data && data === 'q\n') {    process.stdin.pause();  } else if(data) {    var h = crypto.createHash('md5');    var s = h.update(data).digest('hex');    console.log(s);    process.stdout.write('> ');  }});

• child_process.exec

var exec = require('child_process').exec;if(process.argv.length !== 3) {    console.log('not sopport');    process.exit(-1);}var cmd = process.platform === 'win32' ? 'type' : 'cat';       //注意不同平台exec(cmd + ' ' + process.argv[2], function (err, stdout, stderr) {  if(err) return console.log(err);  console.log(stdout.toString('utf8'));  console.log(stderr.toString('utf8'));});

• 使用进行加密对比
• 使用来制造,验证token
