包含到cocos2d-x里的tcpsocket源码

声明：本文参考了langresser发布的blog“跨平台的游戏客户端Socket封装 ”
Socket处理是异步非阻塞的，所以可以放心的放到主线程处理消息，并且在原作者的基本上进行了系列优化，考虑了客户端可能建立多个SOCKET，因此加入了Manager概念，与cocos2d-x进行了融合。
本文基于cocos2d-x3.0+VS2012

另外，
在extensions/cocos-ext.h文件内加入
#include "network/TCPSocket.h"
在extensions/Android.mk文件内加入，使其在linux下能够编译到
network/TCPSocket.cpp \
使用例子，代码片段：
/////////////////////////////////////////////// // 创建SOCKET管理器 CREATE_TCPSOCKETMGR(this); // 创建并添加SOCKET，参数：服务器IP，端口，自定义的SOCKET_ID标识 sSocketMgr.createSocket("192.168.0.183", 7502, 1); // 注册协议，参数：包头，回调函数 sSocketMgr.register_process(0x10, SCT_CALLBACK_2(HelloWorld::login, this)); // 注册消息截获事件，注册此事件后可以截获收到的所有消息，若回调函数返回true则本次事件会继续分发注册过的协议，返回false则不分发 sSocketMgr.register_all_process(SCT_CALLBACK_1(HelloWorld::process, this)); // 定义协议包 WorldPacket packet; packet.clear(); // 设置协议头 packet.SetOpcode(0x0010); packet << uint16(0x0010) << uint16(0)// 协议长度 << uint32(1) << uint32(0); // 加入字符串数据(uint8表示字符串长度所占字节，此处为1字节) packet.AppendPacketString<uint8>(std::string("aaa:88889083:d5956683c17d7e284d33ee295b277b52")); // 设置协议长度 packet.SetLength(packet.size()); // 发送数据 sSocketMgr.SendPacket(1, &packet); ///////////////////////////////////////////////
回调函数例子：
1 // 注册单个协议回调函数（样例)，参数：SOCKET_ID标识，数据包 2 void process_login(int _tag, WorldPacket & packet); 3 // 注册单个协议回调函数（样例)，参数：SOCKET_ID标识，协议头，数据包 4 bool process_all(int _tag, int _cmd, WorldPacket & packet); 5 // 断线事件 6 void onDisconnect(int _tag);
取数据例子：
WorldPacket packet ;
// 取整形数据 uint16 opcode; uint16 len; uint32 serial; float fl;
packet >> opcode; packet >> len; packet >> serial; packet >> fl;
// 取字符串 String oldPwd, newPwd; packet.GetPacketString<uint8>(&packet, oldPwd); packet.GetPacketString<uint8>(&packet, newPwd);
写得比较草，如果看不懂的，好的建议和意见可以给我留言。
如果有不同的，好的思路也可以提出来，一起探讨。。
