C++对Lua中table进行读取、修改和创建

C++代码：

// LuaAndC.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"


#include <iostream>  
#include <string.h>  
using namespace std;  
   
extern "C"  
{  
    #include "lua.h"  
    #include "lauxlib.h"  
    #include "lualib.h"  
}  


int _tmain(int argc, _TCHAR* argv[])
{
	 //1.创建一个state  
    lua_State *L = luaL_newstate();  

	luaL_openlibs(L);
	luaL_dofile(L,"Hello.lua");
	
	//获取table的值
	lua_getglobal(L,"str");

	//会将get的对应项压到栈顶
	lua_getfield(L,1,"name");
	lua_getfield(L,1,"age");

	if(lua_isstring(L,2))
	{
		cout<<"name= "<<lua_tostring(L,-2)<<endl;
	}
	if(lua_isnumber(L,3))
	{
		cout<<"age= "<<lua_tonumber(L,-1)<<endl;
	}
	lua_pop(L,2);

	//修改table的项
	lua_pushfstring(L,"So so");//改完弹出
	lua_setfield(L,1,"name");
	lua_getfield(L,1,"name");
	if(lua_isstring(L,2))
	{
		cout<<"name1= "<<lua_tostring(L,2)<<endl;
	}
	lua_pop(L,2);

	//新建table
	lua_newtable(L); //压栈
	lua_pushnumber(L,11);
	lua_pushstring(L,"New");
	lua_setfield(L,1,"name");
	lua_setfield(L,1,"age");
	lua_getfield(L,1,"name");
	lua_getfield(L,1,"age");
	if(lua_isstring(L,2))
	{
		cout<<"name= "<<lua_tostring(L,2)<<endl;
	}
	if(lua_isnumber(L,3))
	{
		cout<<"age= "<<lua_tonumber(L,3)<<endl;
	}

	lua_pop(L,3);

    //关闭state  
    lua_close(L);  
	
	int i;
	cin>>i;
    return 0 ;  
}

 

Lua代码：

str={name="Hunter",age=18}
