如何使用HTTP实现文本传输，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
HTTP协议即超文本传送协议(Hypertext Transfer Protocol )，是Web联网的基础，HTTP协议是建立在TCP协议之上的一种应用。由于HTTP在每次请求结束后都会主动释放连接，因此HTTP连接是一种短连接。HTTP遵循请求（Request）/应答（Response）模型。所以一定需要实现请求(Gk8HttpRequest)。同时需要实现返回(Gk8HttpResponse)。在游戏研发编程中HTTP请求类型常用的就是GET和POST。框架设计中就需要实现完成HTTP请求和返回的Gk8HttpClient类。HTTP不管是文本传输还是二进制传输Gk8HttpClient类都能兼容完成响应的功能。HTTP文本传输方便简洁。实现轻量级通信的最佳方式。
libCurl作为是一个多协议的便于客户端使用的URL传输库，基于C语言，提供C语言的API接口。底层通信都是使用libCurl库来完成。具体可找相关资料和参阅相关代码。C语言封装开发的优势就是支持跨平台。Windows平台，安卓平台，IOS平台。跨平台迁移代码无需再次开发。一劳永逸的解决通信问题。为了方便开发时HTTP并发和回调。又实现了Gk8HttpServlet类(httpnet目录中)。高度封装的代码目的就是易于理解便于使用。
