lua_getfield(L,-1,"name");//lua_getfield(L,-1,"name")的作用等价于 lua_pushstring(L,"name") + lua_gettable(L,1) constchar*name = lua_tostring(L,-1);//在栈顶取出数据 printf("name:%s\n", name); lua_pushstring(L,"id");//压入id
这里isprint(ch)的ch是一个char。而按照https://en.cppreference.com/w/c/string/byte/isprint的说法。这个函数接受的参数虽然是个int但它必须是个unsigned char或者EOF。否则是UB。实际上,这里对于utf-8字符串或者unicode,这里取到的ch可能为负数,于是隐式转换成int后不是一个unsigned char。在MSVC下此处会崩溃。
