Question

我在使用Lua5.1的C ++应用程序中使用VS2015。我正在运行一个非常简单的Lua脚本，没有问题，原始lua工作正常。但是当我尝试导入lua模块“socket.http”时，我的应用程序不喜欢它，因为我想它找不到模块。

我的问题是如何允许我的lua脚本（从c ++运行）访问lua模块，如socket.http？

我的project.cpp

#include "stdafx.h"
#include <iostream>

extern "C"
{
#include <../dependancies/lua51/include/lua.h>
#include <../dependancies/lua51/include/lauxlib.h>
#include <../dependancies/lua51/include/lualib.h>
}

void report_errors(lua_State *L, int status)
{
    if (status != 0)
    {
        printf("-- %s\n", lua_tostring(L, -1));
        lua_pop(L, 1); // remove error message
    }
}

int main()
{
    // create a Lua state
    lua_State* L = luaL_newstate();

    // load standard libs 
    luaL_openlibs(L);

    int lscript = luaL_dofile(L, "test1.lua");

    report_errors(L, lscript);

    system("PAUSE");
    return 0;
}

test1.lua

local http = require("socket.http")

错误

模块的规则是相同的，无论您是从c ++还是从Lua命令行解释器启动脚本。
你必须在Lua搜索者/加载者试图找到它的路径中有该模块。查看搜索到的路径列表，在一个搜索路径中放置http dll（使用与项目相同的设置编译，以防静态链接Lua）。并且您必须将该模块与您的程序一起分发，不要期望它安装在用户的PC上。

在从C ++调用的脚本中需要Lua模块
