文字描述比较少，有遇到问题可以V本人。
公司wifi需要登录认证网页，手动输入账号和密码，验证完成后，才能开始上网。如果电脑合盖，或者睡眠。再次打开需要重新在打开网页，输入账号密码，连接。就和我们在KFC或者是机场、酒店，连接了wifi会弹出一个认证的窗口。

首先想到的是把url的请求地址拿出来，通过curl的请求去完成认证。
这个有一个问题是当Captive Network Assistant弹出的时候，网络会被拦截，这个英语翻译成中文的意思强制网络助理。只要有这个弹窗在，网络都会被终止（没有实际性的原理，亲测是网络被拦截）最早是使用sleepwatcher来执行，当mac唤醒的时候，执行脚本。
有个问题就是当切换网络的时候，就没办法执行脚本了。只能在唤起的时候使用
解决方案
使用hammerspoon+lua+applescript来解决
思路
- 监听网络切换和电脑的唤醒、解锁
- 监听到事件，查找是否有目标wifi在，如果有，强制连接目标wifi
- 监听
Captive Network Assistant的弹窗，如果弹窗存在，执行applescript的脚本，自动输入账号密码
安装hammerspoon
- 使用brew安装
没有安装过brew的话可以先执行
/usr/bin/ruby -e "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/install)"
然后安装
brew install hammerspoon --cask
- 下载app，自行百度或者官网下载。这边就不做更多的说明
- 安装完成后，顶部会有一个锤子的图标，点击红框部分给到权限。可以开机的时候就启动hammerspoon

-
小技巧，可以把图标也隐藏。通过command + 空格，唤起搜索，搜索ha开头，可以再打开设置界面。

在~目录下可以看到有这个文件。hammerspoon会先执行init.lua

开发环境
init.lua 判断了如果是自己的mac，才会执行自动更新脚本。这样只要有修改，hammerspoon的控制台就会有log，方便做调试
require "wifi.wifi"
if (hs.host.localizedName() == 'Radish') then
local pathwatcher = require "hs.pathwatcher"
local alert = require "hs.alert"
-- 开启自动重载配置文件
function autoReload()
function reloadConfig(files)
doReload = false
for _, file in pairs(files) do
if file:sub(-4) == ".lua" then
doReload = true
end
end
if doReload then
hs.reload()
end
end
pathwatcher.new(os.getenv("HOME") .. "/.hammerspoon", reloadConfig):start()
end
autoReload()
end
wifi
wifi的脚本思路和上面所述的一样。主要监听了
监听电脑休眠和唤醒和wifi发生改变和创建应用程序监控器。唤醒的时候，去扫描后台有没有目标WIFINAME，有的话，就连接目标wifi，执行applescript脚本
local WIFINAME = "Dianei";
-- local USERNAME = "1111"
-- local PASSWORD = "2222"
-- 异步执行shell
function asyncSheel(cmd, callback)
hs.task.new("/bin/sh", function(exitCode, stdOut, stdErr)
if exitCode ~= 0 then
print("Error executing command: " .. stdErr)
callback()
else
print("Command output: " .. stdOut)
callback(stdOut)
end
end, {"-c", cmd}):start()
end
-- 执行shell脚本
function shell(cmd)
local success,obj,descriptor = hs.osascript.applescript(string.format('do shell script "%s"', cmd))
return success,obj,descriptor
end
-- 判断网络是否连接
function isNet()
local success,obj,descriptor = shell("ping -o -t 1 baidu.com")
if (success and obj ~= nil and string.find(descriptor, '1 packets received')~= nil) then
return true
else
return false
end
end
function wifiCallback(watcher, message, interface)
local ssid = hs.wifi.currentNetwork(interface)
if (ssid ~= nil and ssid == WIFINAME) then
print("当前wifi列表中存在"..ssid)
-- scan()
end
end
function caffeinateCallback(event)
if event == hs.caffeinate.watcher.screensDidSleep then
-- 屏幕休眠（屏保开启）
print("screensDidSleep")
elseif event == hs.caffeinate.watcher.screensDidWake then
-- 屏幕唤醒
print("screensDidWake")
elseif event == hs.caffeinate.watcher.screensDidLock then
print("screensDidLock")
elseif event == hs.caffeinate.watcher.screensDidUnlock then
-- 屏幕解锁
print("screensDidUnlock")
-- 强制开启wifi的按钮
asyncSheel("networksetup -setairportpower en0 on", function()
print('强制开启了wifi按钮')
-- 后台扫描WiFi热点
hs.wifi.backgroundScan(function(networks)
-- 处理扫描结果
print("wifi 扫描完成")
for i, network in ipairs(networks) do
if (network.ssid == WIFINAME or network.bssid == WIFINAME) then
print("找到 wifi名字了")
-- 连接wifi 等待cna的弹窗
hs.wifi.associate(WIFINAME, "")
break
end
end
end)
end)
elseif event == hs.caffeinate.watcher.systemWillSleep then
print("systemWillSleep")
elseif event == hs.caffeinate.watcher.systemDidWake then
print("systemDidWake")
elseif event == hs.caffeinate.watcher.systemWillPowerOff then
print("systemWillPowerOff")
elseif event == hs.caffeinate.watcher.systemDidPowerOn then
print("systemDidPowerOn")
end
end
-- 应用程序激活事件处理
function applicationCallback(name, event, app)
-- and event == hs.application.watcher.launched
if name == "Captive Network Assistant" or name == "强制网络助理" then
-- 启动
-- print(hs.application.watcher.launched)
-- -- 激活
-- print(hs.application.watcher.activated)
-- 在 Captive Network Assistant 打开时自动输入账号密码
if event == hs.application.watcher.activated then
print("激活cna了 ~ ")
asyncSheel("osascript ~/.hammerspoon/wifi/cna.applescript", function(e)
print("执行完毕")
local haveNet = isNet()
if (haveNet == true) then
hs.alert.show(WIFINAME.."网络已连接")
end
end)
end
end
end
-- 监听电脑休眠和唤醒
hs.caffeinate.watcher.new(caffeinateCallback):start()
-- wifi发生改变
hs.wifi.watcher.new(wifiCallback):start()
-- 创建应用程序监控器
hs.application.watcher.new(applicationCallback):start()
function getDianneiWifi()
return hs.window.filter.new(false):setAppFilter("Captive Network Assistant", { currentSpace = true, allowTitles = "加入“Dianei”" }):getWindows()
end
-- hs.application:getWindow(title)
-- function launchOrNextWindow(name, showName)
-- local findName = showName or name
-- local appName = hs.application.frontmostApplication():name()
-- print("appName")
-- print(appName)
-- if findName ~= appName then
-- hs.application.launchOrFocus(name)
-- else
-- -- local wlist = getWinList(findName)
-- -- local wcount = #wlist
-- -- if wcount > 1 then
-- -- hs.eventtap.keyStroke({'cmd'}, '`')
-- -- else
-- -- local win = wlist[1]
-- -- if win:isMinimized() then win:unminimize() else win:minimize() end
-- -- end
-- end
-- end
-- function mapLaunch(key, name, showName)
-- hs.hotkey.bind({}, key, function()
-- launchOrNextWindow(name, showName)
-- end)
-- end
-- mapLaunch('f1', 'Google Chrome')
-- launchOrNextWindow('iTerm', 'iTerm2')
applescript
