luci实现的wifidog认证服务
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("^*$") or luci.sys.uniqueid(16) local sdt = {id=id, addr=addr, port=port, mac=mac, url=url, timestamp=luci.sys.uptime()} local path = (http.getenv("SCRIPT_NAME") or "") .. "/wdas" session.write(token, sdt) http.header("Set-Cookie", "wdastok=" .. token .. "; path=" .. path) http.write('{url:"http://' .. addr .. ':' .. port .. '/wifidog/auth?token=' .. token .. '"}') else if addr and port and mac then http.write('{error: "' .. translate("Invalid username or password.") .. '"}') else http.write('{error: "' .. translate("Invalid parameter.") .. '"}') end endendfunction auth() --auth/?stage=&ip=&mac=&token=&incoming=&outgoing= local stage, ip, mac, token, incoming, outgoing stage = http.formvalue("stage") ip = http.formvalue("ip") mac = http.formvalue("mac") token = http.formvalue("token") incoming = http.formvalue("incoming") outgoing = http.formvalue("outgoing") token = token and token:match("^*$") local sdt = token and session.read(token) if token and sdt and (mac == sdt.mac) then http.write("Auth: 1") else http.write("Auth: 0") endendfunction ping() --ping/?gw_id=&sys_load=&sys_memfree=&sys_load=&wifidog_uptime= local id, sys_uptime, sys_memfree, sys_load, wifidog_uptime id = http.formvalue("gw_id") sys_uptime = http.formvalue("sys_uptime") sys_memfree = http.formvalue("sys_memfree") sys_load = http.formvalue("sys_load") wifidog_uptime = http.formvalue("wifidog_uptime") if id and sys_uptime and sys_memfree and sys_load and wifidog_uptime then http.write("Pong") else http.write("{error:2}") endendfunction portal() --portal/?gw_id=%s local token, sdt, url token = http.getcookie("wdastok") sdt = token and session.read(token) url = sdt and sdt.url or "http://www.baidu.com" http.redirect(url)endfunction gw_message() local msg = http.formvalue("message") http.write(msg)end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
