关于C解析lua表结构的问题

[燕雀安知鱼之乐]

我在lua程序中创建了一个表,表中存放的是表成员,想在C中读取表成员的成员,表的结构如下

        local req = {};
        req.opcode = GAME_OPCODE.CLI_PLAYCARD_REQ;
        req.sSerialID = 1024;
        req.nCardsCount = 1;
        cards = {}
        cards[1] = {}
        cards[1].color = 0;
        cards[1].value = 1;
        cards[2] = {}
        cards[2].color = 1;
        cards[2].value = 3;
        req.cards = cards;
        sendToSdk(req)

我在C中获取协议要发送的信息

CCard* getCardsFlied(lua_State *L, const char *szKey)
{	OutputDebugString("join getCardsFlied ~~~~");
	CCard cards[20];
	lua_pushstring(L , szKey);   //这个压入的的就是上面的req.cards
	lua_gettable(L , -2);
	int n = lua_objlen(L , -1);
	for (int i = 0; i < n; i ++)
	{	
		lua_rawgeti(L,1,i + 1);
		char buf[20];
		sprintf(buf,"\n%d",i +1);
		OutputDebugString(buf);
		lua_pop(L , 1);
	
	}
	return cards;

}

程序中得到的是card表,我想获取card表的成员color和value的值,请问我该怎么做
求大神帮忙,谢谢

我在脚本之家上看到相关基础http://www.jb51.net/article/55096.htm 自己试验了一下,好像解决了

CCard* getCardsFlied(lua_State *L, const char *szKey)
{
	CCard cards[20];
	lua_pushstring(L, szKey);
	lua_gettable(L,-2);
	for(int i = 0; i < 20; i ++)
	{
		//初始化卡牌属性
	  
		cards[i].m_nColor = -1;
		cards[i].m_nValue = -1;

		//压人对应的卡牌Key值
		lua_pushnumber(L,i + 1);
		lua_gettable(L , -2);
		if (lua_istable(L,-1))
		{
			
			
			//压人卡牌参数"color"
			lua_pushstring(L , "color");
			lua_gettable(L , -2);
			cards[i].m_nColor = lua_tonumber(L , -1);
			lua_pop(L , 1);

			//压人卡牌参数"value"
			lua_pushstring(L , "value");
			lua_gettable(L , -2);
			cards[i].m_nValue = lua_tonumber(L , -1);
			lua_pop(L , 1);
		}
		lua_pop(L , 1);


#ifdef MB_OS_WIN
		char buf[50];
		sprintf(buf,"\n\t cards[%d]:(%d , %d)",i,cards[i].m_nColor,cards[i].m_nValue);
		OutputDebugString(buf);
#endif

	}


	return cards;
}

保存一下,做个笔记
