windows 上 搭建 apache + lua 运行环境
为了搭建apache - lua 好不容易从网上下载到了 mod_lua.so 的windows版本但是始终搞不成,找了N天才发现 这玩意要 apache 2.3+的版本支持, 见此处
但是 apache官方并无 2.3+以上版本 windows 的版本下载,终于找到一个位置
http://www.apachelounge.com/download/
下载了 32位的 apache 2.4的版本,其中便内置了 mod_lua.so o(∩_∩)o 哈哈
在 httpd.conf中开启这个模块,然后新增一行 AddHandler lua-script .lua
在 htdocs下新增 2个lua脚本文件来进行测试即可
info.lua
-- Extend tostring to report function type (C or Lua)
do
local type, tostr = type, tostring
function tostring(obj)
local type, val = type(obj), tostr(obj)
if type == "function" then
type = pcall(coroutine.create, obj) and "Lua " or "C " -- coroutines cannot start at a C function
return type .. val
else
return val
end
end
end
local safe_replacements = {
["<"] = "<",
[">"] = ">",
["&"] ="&",
}
local function safestring(...)
return tostring(...):gsub("[<>&]", safe_replacements):gsub("\n", "<br/>\n")
end
local function emstring(...)
return ""<em>".. safestring(...) .."</em>""
end
local function print_info(info)
