如何使用HTTP实现二进制传输

本篇文章给大家分享的是有关如何使用HTTP实现二进制传输，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。

HTTP实现二进制传输。曾经为这事还纠结过。刚工作时游戏都是端游。基本学习和接触过得都是TCP发送二进制方式。当时刚开始转型研发页游。原来删除的都是C++开发。突然要研究flash搞网页游戏。ActionScript(简称AS)这语言不熟悉。弄网络封装时肯定潜意识设计思路是HTTP实现二进制传输。然后结合网络消息采用工具自动化生成方式。自己不善于HTTP。故意招个比较擅长的人协助搞下底层。我把上面想法告诉他。他斩钉截铁告诉我HTTP肯定无法传输二进制。这让我不爽研究好几天终于搞出来了。有时成长需要时间需要去沉淀。经历过就对如何解决记忆更加深刻。

同理。HTTP传输依然靠Gk8HttpClient类。具体实现参阅。 网络通信3：HTTP实现文本传输。炮弹抽象转实体就是Gk8ByteMaker。 网络通信1：字节流的封装。实现Gk8HttpService类提供发送和接收。设置HttpUrl，设置消息Header，是否压缩等API。方便逻辑应用直接使用。

C++实现HttpService类：Gk8HttpService.h
