var express = require("./node_modules/express"), fs = require("fs"), extTypes = require("./extTypes.js"); var app = express(); var port = 1337; app.listen(port); app.use('/', express.static(__dirname + '/html/')); app.get("/download", function(req, res) { var file = "./upload/20140210/ahg056fg01sa40df8sd9"; var filename = "firefox.png"; var mimetype = extTypes["png"]; res.setHeader('Content-disposition', 'attachment; filename=' + filename); res.setHeader('Content-type', mimetype); var filestream = fs.createReadStream(file); filestream.pipe(res); }); console.log("Start express server");

學習步驟：
1. 檔案網路安全概念。
2. 學習如何將現有下載功能改成轉址方式。

作業：
1. 採用更安全的方式，利用讀檔寫檔設計一個可編輯公告內容的網站。
