　在上传工程之前，对源代码中几个重要的类简单解释一下：

　　Client端

　　WifiApClientManager：对WifiManager的接口进行了封装，以便于进行开启、连接等操作

　　HttpEngineLite：发起Http请求的"引擎"类

　　WifiApClientRequest：请求抽象类，子类WifiApClientGetRecvListRequest，WifiApClientGetFileRequest分别表示获取获取Server端待传文件列表请求及获取Server端指定文件请求，使用HttpEngineLite执行具体操作

　　NanoHTTPClient：提供获取Server端待传文件列表，获取Server端指定文件等操作接口，使用线程池管理WifiApClientRequest

 

　　Server端

　　WifiApServerManager：对WifiManager的接口进行了封装，以便于进行开启AP，配置AP等操作

　　WifiApServerUtil：定义了Android AP通用网关IP

　　NanoHTTPD：此类为引用的开源代码（A simple, tiny, nicely embeddable HTTP server in Java）

　　NanoHTTPServer：NanoHTTPD的子类，实现其接口，返回相应的HttpResponse
