HTTP實現二進位制傳輸。曾經為這事還糾結過。剛工作時遊戲都是端遊。基本學習和接觸過得都是TCP傳送二進位制方式。當時剛開始轉型研發頁遊。原來刪除的都是C++開發。突然要研究flash搞網頁遊戲。ActionScript(簡稱AS)這語言不熟悉。弄網路封裝時肯定潛意識設計思路是HTTP實現二進位制傳輸。然後結合網路訊息採用工具自動化生成方式。自己不善於HTTP。故意招個比較擅長的人協助搞下底層。我把上面想法告訴他。他斬釘截鐵告訴我HTTP肯定無法傳輸二進位制。這讓我不爽研究好幾天終於搞出來了。有時成長需要時間需要去沉澱。經歷過就對如何解決記憶更加深刻。

同理。HTTP傳輸依然靠Gk8HttpClient類。具體實現參閱。[網路通訊3：HTTP實現文字傳輸](http://blog.itpub.net/69975060/viewspace-2693823/)。炮彈抽象轉實體就是Gk8ByteMaker。具體實現參閱。[網路通訊1：位元組流的封裝](http://blog.itpub.net/69975060/viewspace-2693162/)。實現Gk8HttpService類提供傳送和接收。設定HttpUrl，設定訊息Header，是否壓縮等API。方便邏輯應用直接使用。

C++實現HttpService類：Gk8HttpService.h
