用 node js 及 express 寫個簡單的 https server

// 參考文章:
//  https://nodejs.org/api/https.html
//  http://stackoverflow.com/questions/11744975/enabling-https-on-express-js
// npm install express

// exps.js
var https   = require("https");
var fs      = require("fs");
var url     = require("url");
var path    = require("path");
var express = require("express");
var options = {
    key:  fs.readFileSync('mypass.key'),
    cert: fs.readFileSync('mypass.crt')
};

function getDOC(req,res) {
    var uri = url.parse(req.url).pathname;
    var filename = path.join(process.cwd()+"/www", uri);                    // add doc root: /www
    fs.access(filename, function(accessErr) {
        if(accessErr) {   res.send("File not found");  return; }
        if (fs.statSync(filename).isDirectory()) filename +='/mybaby.htm';  // default html document
        fs.readFile(filename, "binary", function(err, file) {
            if(err) { res.send(err); return; }        
            res.writeHead(200);
            res.write(file, "binary");
            res.end();
        });      
    })
}
 
var app = express();
    app.get('/*',getDOC);

var server=https.createServer(options, app);
server.listen(4443, function() {
console.log("HTTPS sever started at port %s",server.address().port);
});

// 再寫個 Makefilet 產生 ssl 所需要的檔案及目錄,方便使用及執行.
// Makefile
run: genkey exps.js
@js exps.js

genkey: mypass.crt www

mypass.key:
openssl genrsa -out mypass.key 2048
mypass.csr: mypass.key
openssl req -new -key mypass.key -out mypass.csr
mypass.crt:  mypass.csr mypass.key
openssl x509 -req -in mypass.csr -signkey mypass.key -out mypass.crt
www:
mkdir www

clean:
rm -f mypass.*
