MINA服务端与C++客户端通讯（2）

Java与C++通讯还有编码转码的问题存在，假设通讯编码采用UTF-8

C++客户端发送时需要转码成UTF-8编码，接收服务端应答消息后再转回Unicode或者GBK编码

下面给出完成的C++客户端通讯示例：

void Transcoding(LPCTSTR src, UINT srcCode, string& dest, UINT destCode)??
{??
??? int len = MultiByteToWideChar(srcCode, 0, src, -1, NULL, 0);????
??? WCHAR* srcTemp = new WCHAR[len];????
??? MultiByteToWideChar(srcCode, 0, src, -1, srcTemp, len);????
??? len = WideCharToMultiByte(destCode, 0, srcTemp, -1, NULL, 0, NULL, NULL);????
??? char* destTemp = new char[len];????
??? WideCharToMultiByte(destCode, 0, srcTemp, -1, destTemp, len, NULL, NULL);????
?
??? dest = destTemp;??
?
??? delete []srcTemp;????
??? delete []destTemp;????
}?

int _tmain(int argc, _TCHAR* argv[])?
{?
??? // client connect?
??? CXSocket client;?
??? client.initWinSocket();?
??? client.setAddress("127.0.0.1");?
??? client.setPort(1234);?
??? client.setProtoType(TCP);?
??? int ret = client.connect();?
??? if(ret < 0)?
??? {?
??????? getchar();?
??????? return 0;?
??? }?
?
??? // 加通讯协议头demo?
??? // client send?
??? char send[] = {"CXSocket 第一个测试用例."};?
?
??? string utf8;?
??? Transcoding(send, CP_ACP, utf8, CP_UTF8);?
?
??? XNET::TPacketHeader sendHeader;?
??? sendHeader.m_HeaderSig = 0xABCD;?
??? swap_2(sendHeader.m_HeaderSig);?
??? sendHeader.m_Length = (int)utf8.length();?
??? swap_4(sendHeader.m_Length);?
?
??? char buffer[1024] = {0};?
??? memcpy(buffer, &sendHeader, XNET::TCP_HEADLEN);?
??? memcpy(&buffer[XNET::TCP_HEADLEN], utf8.c_str(), utf8.length());?
??? client.sendBuf(buffer, (int)(XNET::TCP_HEADLEN + utf8.length()));?
?
??? // client recv?
??? XNET::TPacketHeader recvHeader;?
??? client.receiveBuf(&recvHeader, XNET::TCP_HEADLEN);?
??? swap_2(recvHeader.m_HeaderSig);?
??? swap_4(recvHeader.m_Length);?
??? char* recv = new char[recvHeader.m_Length + 1];?
??? memset(recv, 0, recvHeader.m_Length + 1);?
??? client.receiveBuf(recv, recvHeader.m_Length);?
??? string ansi;?
??? Transcoding(recv, CP_UTF8, ansi, CP_ACP);?
?
??? client.close();?
??? client.uninitWinSocket();?
?
??? getchar();?
?
??? return 0;?
