esp8266 代码

使用 arduino ide 烧录esp8266代码，如下。

// 引入 wifi 模块
#include <ESP8266WiFi.h>
static WiFiClient espClient;

// 引入阿里云 IoT SDK
#include <AliyunIoTSDK.h>

// 设置产品和设备的信息，从阿里云设备信息里查看
#define PRODUCT_KEY ""
#define DEVICE_NAME ""
#define DEVICE_SECRET ""
#define REGION_ID "cn-shanghai"

// 设置 wifi 信息
#define WIFI_SSID ""
#define WIFI_PASSWD ""

// 初始化 wifi 连接
void wifiInit(const char *ssid, const char *passphrase)
{
    WiFi.mode(WIFI_STA);
    WiFi.begin(ssid, passphrase);
    while (WiFi.status() != WL_CONNECTED)
    {
        delay(1000);
        Serial.println("WiFi not Connect");
    }
    Serial.println("Connected to AP");
}

// 属性修改的回调函数
void brightnessCallback(JsonVariant p)
{
    int brightness = p["table_lamp:brightness"];
      // 改变亮度
    if (brightness == 1)
    {
      switch_brightness();
    } 
}

// 属性修改的回调函数
void lightingtoneCallback(JsonVariant p)
{
    int lightingtone = p["table_lamp:lightingtone"];
     // 改变色调
    if (lightingtone == 1)
    {
      switch_lightingtone();
    } 
}

void setup() {
   Serial.begin(9600);
    // 初始化 wifi
    wifiInit(WIFI_SSID, WIFI_PASSWD);
    // 初始化 iot，需传入 wifi 的 client，和设备产品信息
    AliyunIoTSDK::begin(espClient, PRODUCT_KEY, DEVICE_NAME, DEVICE_SECRET, REGION_ID);
    // 绑定一个设备属性回调，当远程修改此属性，会触发 powerCallback
    AliyunIoTSDK::bindData("table_lamp:brightness", brightnessCallback);
        // 绑定一个设备属性回调，当远程修改此属性，会触发 powerCallback
    AliyunIoTSDK::bindData("table_lamp:lightingtone", lightingtoneCallback);
}

void loop() {
  AliyunIoTSDK::loop();
}

//改变亮度
void switch_brightness(){
  pinMode(LED_BUILTIN, HIGH);
  pinMode(16, HIGH);
  delay(100);
  pinMode(16, LOW);
  pinMode(LED_BUILTIN, LOW);
}

//改变灯光色调
void switch_lightingtone(){
  pinMode(LED_BUILTIN, HIGH);
  pinMode(16, HIGH);
  delay(1200);
  pinMode(16, LOW);
  pinMode(LED_BUILTIN, LOW);
}

阿里云IOT平台

完成实例、产品、设备注册。
配置物模型数据，相当于制作一个抽象的、数字化的台灯。通过这个物模型，控制实际设备。

模型TSL如下。

阿里云云函数

通过 Serverless 可以无服务器部署后端，方便快捷，关键还免费（小额使用）。

云函数代码如下。

'use strict';
exports.main = async (event, context) => {
    //event为客户端上传的参数
    console.log('event : ', event)
    const Core = require('@alicloud/pop-core');
    var client = new Core({
        accessKeyId: '',
        accessKeySecret: '',
        // securityToken: '<your-sts-token>', // use STS Token
        endpoint: 'https://iot.cn-shanghai.aliyuncs.com',
        apiVersion: '2018-01-20'
    });
    let b = 0;
    let l = 0;
    if(event["isBrightness"] == 1){
        b = 1;
        l = 0;
    }else{
        b = 0;
        l = 1;
    }

    var params = {
        "IotInstanceId": "iot-06z00g6fsqfbsgl",
        "ProductKey": "gs6cY8aZKGQ",
        "DeviceName": "light001",
        "Items": "{\"table_lamp:brightness\":"+b+",\"table_lamp:lightingtone\":"+l+"}"
    }

    var requestOption = {
        method: 'POST'
    };

    let res = client.request('SetDeviceProperty', params, requestOption).then((result) => {
        // console.log(JSON.stringify(result));
        return result;
    }, (ex) => {
        // console.log(ex);
        return ex;
    })
    return res;
};

我的台灯APP

APP基于vue,使用uni-app生成。

图示如下。

关键代码如下。

<template>
    <view class="bg">
        <view class="container">

转发订阅消息脚本

因为我的手机是Redmi k30 pro, 所以想要接入小爱同学，但是小米的IOT开发者只支持企业入驻。所以只能借助巴法云物联网平台，然后使用脚本做消息转发来接入小爱同学。

脚本使用python编写，共有两个线程，子线程用来维持心跳。
