navigator.userAgent偽装準備
無料動画 GyaO!をLinuxでも利用したい．
GyaO!「使い方ガイド」をご利用いただくには、以下の環境が必要です。
Yahoo! JAPAN ヘルプセンター
Chromium on Lubuntu 13.10では，OSが不明とされ，利用できない．世に出ているUserAgent詐称コードはHTTPヘッダ情報をのみ書き換える．GyaO!はjavascriptのnavigator.userAgentを参照するため，効果が無い．
Firefoxでは別途UAを詐称した上でUser-Agent JS Fixer :: Add-ons for Firefoxを適用することでクリアできるようだ．
OperaはSilverlightをインストールした上でuserscriptを導入し，打開していたようだ．kyu3 - OperaでGyao!を見られるようにするUser JSを追加．今では標準で回避策が用意されているようだ．GyaOを観たい - Opera Wiki．（Windowsの話じゃん）
Chromiumでの視聴を諦め，「Firefox+UA詐称+User-Agent JS Fixer」が正解な気がしてきた．

- navigator.userAgent は JS で書き換えられる
try { if (!Object.prototype.__defineGetter__ && Object.defineProperty({}, "x", { get: function(){ return true } }).x ) { Object.defineProperty(Object.prototype, "__defineGetter__", { enumerable: false, configurable: true, value: function(name, func) { Object.defineProperty(this,name, { get: func, enumerable: true, configurable: true }); } }); Object.defineProperty(Object.prototype, "__defineSetter__", { enumerable: false, configurable: true, value: function(name, func) { Object.defineProperty(this,name, { set: func, enumerable: true, configurable: true }); } }); } } catch (defPropException) { /* Do nothing if an exception occurs */ } var __original = navigator; var navigator = {}; navigator.__proto__ = __original; navigator.__defineGetter__ ? navigator.__defineGetter__("userAgent", function () { return "foo"; }) : navigator.userAgent = "foo"; document.write("navigator.userAgent = " + navigator.userAgent);navigator.userAgent は当てにならないテスト - jsdo.it - Share JavaScript, HTML5 and CSS
