luci实现的wifidog认证服务

wifidog.pro

利用luci写了个wifidog认证服务，实现直接openwrt路由器本地认证。直接安装ipk安装包，然后修改/etc/wifidog.conf文件(需要先安装wifidog)，如下：

AuthServer {    Hostname 192.168.1.1    Path /cgi-bin/luci/wdas/    MsgScriptPathFragment gw_message/?}

主要的源码如下：

module("luci.controller.wifidog.wdas", package.seeall)local session = require "luci.wifidogsession"local http = luci.httplocal translate = luci.i18n.translatelocal wdcfg = require("luci.wifidogconfig")function index()    local page    = node("wdas")    page.target   = alias("wdas", "login")    page.order    = 90    page.i18n = "wifidogauth"    page.setuser  = "nobody"    page.setgroup = "nogroup"    entry({"wdas", "login"}, call("login"))    entry({"wdas", "logincheck"}, call("logincheck"))    entry({"wdas", "auth"}, call("auth"))    entry({"wdas", "ping"}, call("ping"))    entry({"wdas", "portal"}, call("portal"))    entry({"wdas", "gw_message"}, call("gw_message"))endfunction login()    --login/?gw_id=&gw_address=&gw_port=&mac=&url=    luci.template.render("wifidog/wdas_login")endfunction logincheck()    local username, password = wdcfg.auth.username, wdcfg.auth.password    local user, pwd, id, addr, port, mac, url, token    user = http.formvalue("user")    pwd = http.formvalue("pwd")    id = http.formvalue("gw_id")    addr = http.formvalue("gw_address")    port = http.formvalue("gw_port")    mac = http.formvalue("mac")    url = http.formvalue("url")    token = http.getcookie("wdastok")    http.prepare_content("application/json")    if addr and port and mac and (user == username) and (pwd == password) then        token = token and token:match("^[a-f0-9]*$") or luci.sys.uniqueid(16)        local sdt = {id=id, addr=addr, port=port, mac=mac, url=url, timestamp=luci.sys.uptime()}        local path = (http.getenv("SCRIPT_NAME") or "") .. "/wdas"        session.write(token, sdt)        http.header("Set-Cookie", "wdastok=" .. token .. "; path=" .. path)        http.write('{url:"http://' .. addr .. ':' .. port ..            '/wifidog/auth?token=' .. token .. '"}')    else        if addr and port and mac then            http.write('{error: "' .. translate("Invalid username or password.") .. '"}')        else            http.write('{error: "' .. translate("Invalid parameter.") ..

源码编译说明：
modules目录下的wifidogauth目录放到./feeds/luci/modules/下。

po/zh_CN/wifidogauth.po文件放到./feeds/luci/po/zh_CN/下。

./feeds/luci/contrib/package/luci/Makefile增加如下语句：

$(eval $(call module,wifidogauth,wifidog auth server,+luci-base))

然后 make menuconfig在luci-->Modules下找到luci-mod-wifidogauth选上。

make package/feeds/luci/luci/compile V=s

认证的用户名、密码的配置文件路径/etc/config/wifidogauth
