轉址下載用法
Node.js (main.js)：
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。
