esp01s连接阿里云平台代码

以下是ESP01S连接阿里云平台的代码示例：

#include <ESP8266WiFi.h>
#include <PubSubClient.h>
#include <ESP8266WiFiMulti.h>
#include <WiFiClientSecure.h>
#include <AliyunIoTSDK.h>

// 阿里云平台的配置信息
#define PRODUCT_KEY "your_product_key"
#define DEVICE_NAME "your_device_name"
#define DEVICE_SECRET "your_device_secret"
#define REGION_ID "cn-shanghai"

// WiFi网络的配置信息
const char* ssid = "your_ssid";
const char* password = "your_password";

// MQTT客户端的配置信息
const char* mqttServer = "your_mqtt_server";
const char* mqttUser = "your_mqtt_user";
const char* mqttPassword = "your_mqtt_password";
const char* mqttClientId = "your_mqtt_client_id";
const int mqttPort = 1883;

// 创建WiFi连接和MQTT客户端对象
ESP8266WiFiMulti WiFiMulti;
WiFiClientSecure wifiClient;
PubSubClient mqttClient(wifiClient);

// 创建阿里云IoT SDK对象
AliyunIoTSDK iotSdk(PRODUCT_KEY, DEVICE_NAME, DEVICE_SECRET, REGION_ID);

void setup() {
  Serial.begin(115200);

  // 连接WiFi网络
  WiFiMulti.addAP(ssid, password);
  while (WiFiMulti.run() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }

  // 连接MQTT服务器
  wifiClient.setInsecure();
  mqttClient.setServer(mqttServer, mqttPort);
  mqttClient.setCallback(mqttCallback);
  while (!mqttClient.connected()) {
    Serial.println("Connecting to MQTT server...");
    if (mqttClient.connect(mqttClientId, mqttUser, mqttPassword)) {
      Serial.println("Connected to MQTT server!");
    }
    else {
      Serial.print("Failed to connect to MQTT server, rc=");
      Serial.println(mqttClient.state());
      delay(5000);
    }
  }

  // 初始化阿里云IoT SDK
  iotSdk.begin(mqttClient);
}

void loop() {
  // 执行阿里云IoT SDK循环处理
  iotSdk.loop();
}

// MQTT消息回调函数
void mqttCallback(char* topic, byte* payload, unsigned int length) {
  // 处理MQTT消息
}
