id = '4567'  -自己设置自己的id替换4567
ssid = 'wifi名'
ssidpwd = 'wifi密码'
wifi.setmode(wifi.STATION)
wifi.sta.config(ssid,ssidpwd)    --set your ap info !!!!!!
wifi.sta.autoconnect(1)
led1 = 3  
led2 = 4  
gpio.mode(led1, gpio.OUTPUT)  
gpio.mode(led2, gpio.OUTPUT)  
function startServer()

ESP8266 Web Server

"; buf = buf.."

GPIO0

"; buf = buf.."

GPIO2

"..'

Raw Data To MCU:


'..pl; local _on,_off = "","" if(_GET.pin == "ON1")then gpio.write(led1, gpio.LOW); print('on led1') elseif(_GET.pin == "OFF1")then gpio.write(led1, gpio.HIGH); print('off led1') elseif(_GET.pin == "ON2")then gpio.write(led2, gpio.LOW); print('on led2') elseif(_GET.pin == "OFF2")then gpio.write(led2, gpio.HIGH); print('off led2') end conn:send(buf); collectgarbage(); end) conn:connect(8001,"eiot.club") end tmr.alarm(1, 1000, 1, function() if wifi.sta.getip()==nil then print("Connect AP, Waiting...") else tmr.stop(1) startServer() end end)

修改为自己的程序:1,2,3行分别改为自己的id(自定义),mcu可连接公网的路由器ssid和密码

如果id为4567,访问页面地址为:http://eiot.club/proxy/4567/index.html

 上述页面已经停止分享,服务器需要自己部署:https://github.com/IoTServ/McuNode-server

其中4567可替换为自定义idindex.html可换为任意字符串,不影响连接,mcu可以获取此参数,建议为模拟文件名,至此,你就可以从公网随意访问nodemcu页面啦!(测试阶段,当前只支持Get方法通过url参数传递参数)
