像oslib，debuglib一样，我如何在内部将套接字嵌入Lua? [英] How could I embedded socket in Lua internally, just like oslib, debuglib?

问题描述

我想实现类似将套接字功能嵌入我的Lua构建中的功能. 因此，我不再需要复制socket.core.dll(只是为了好玩).

I want to implement the function like embedding the socket function in my Lua build. So I don't need to copy socket.core.dll any more (just for fun).

我搜索了邮件列表，看到一些人在讨论这个话题， http://lua-users.org/lists/lua- l/2005-10/msg00269.html

I search the maillist, and see some guys discuss the topic, http://lua-users.org/lists/lua-l/2005-10/msg00269.html

但是我对详细步骤有疑问，谁能给我详细的步骤来更改lua和luasocket代码以使它们协同工作(而不是使用dll方法).

But I have question for the details steps, who could give me a detailed steps for changing the lua and luasocket code to make them work together (not with dll method).

我使用VC2008在Windows xp中尝试了以下步骤:

I tried these steps in windows xp with VC2008:

1)将luasocket代码复制到Lua项目中.

1) copy luasocket code to Lua project.

2)添加一些代码

static const luaL_Reg lualibs[] = {
  {"", luaopen_base},
  {LUA_LOADLIBNAME, luaopen_package},
  {LUA_TABLIBNAME, luaopen_table},
  {LUA_IOLIBNAME, luaopen_io},
  {LUA_OSLIBNAME, luaopen_os},
  {LUA_STRLIBNAME, luaopen_string},
  {LUA_MATHLIBNAME, luaopen_math},
  {LUA_DBLIBNAME, luaopen_debug},
  {LUA_SOCKETLIBNAME, luaopen_socket_core}, // add this line
  {LUA_MIMELIBNAME, luaopen_socket_core}, // add this line
  {NULL, NULL}
};

3)构建项目，然后运行它.

3) build the project, and run it.

当我键入print(socket._VERSION)时，它显示luasocket 2.0.2，这是正确的.

When I type print(socket._VERSION), it shows luasocket 2.0.2, it is correct.

当我键入print(socket.dns.toip("localhost"))时，它显示127.0.0.1 table: 00480AD0，这也是正确的.

When I type print(socket.dns.toip("localhost")), it shows 127.0.0.1 table: 00480AD0, it is correct too.

但是当我尝试使用其他功能(例如绑定)时，它将无法工作.

But when I try to use other features, for example bind, it can't work.

谁能告诉我原因?

推荐答案

您需要通过以下方式将luasocket内容放入package.preload表中:

you need put luasocket stuff into the package.preload table, in this way:

lua_getfield(L, LUA_GLOBALSINDEX, "package");
lua_getfield(L, -1, "preload");
lua_pushcfunction(L, luaopen_socket_core);
lua_setfield(L, -2, "socket.core");

// add mime.core yourself...
