79 Secure your projects with HTTPS Express

生成SSL证书

openssl genrsa -out privkey.pem 1023

openssl req -new -key privkey.pem -out certreq.csr

openssl 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');

});

81 Develop for multiple platforms

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

83 Run command line scripts Unix like

运行node脚本

//hello

#!/usr/bin/env node     // 正常情况下可以改成#!usr/local/bin/node

console.log('hello');

//权限

chmod 755 hello        //0755 = User:rwx Group:r-x World:r-x

//运行

./hello

86 Understand the basics of stdin stdout

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('> ');

  }

});

87 Launch processes with the exec function

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'));

});
