esp8266 发送消息给钉钉机器人
钉钉机器人使用大家可以从官网了解如何添加一个钉钉机器人 https://open.dingtalk.com/document/robots/custom-robot-access源码直接附上源码，webhookUrl 为钉钉机器人的webhook地址，格式类似这种：“https://oapi.dingtalk.com/robot/send?access_token=XXXXXX”#include <Arduino.h>
#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include <WiFiClientSecureBearSSL.h>
#include <ArduinoJson.h>
//WiFi连接信息（注意：需要自行修改以下内容否则ESP8266无法连接WiFi）
#define ssid "xxxx" //WiFi名称
#define password "xxxxxxx"//WiFi密码
String webhookUrl = "https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxx";
int PIR_sensor = 12; //指定PIR模拟端口 A5
int LED = 2; //指定LED端口 13
int val = 0; //存储获取到的PIR数值
void httpPostRequest(String requestUrl, String body) {
Serial.println("http post " + String(requestUrl) + " body \n" + String(body));
WiFiClientSecure client;
HTTPClient httpClient;
client.setInsecure();
httpClient.begin(client, requestUrl);
httpClient.addHeader("Content-Type", "application/json");
int httpResponseCode = httpClient.POST(body);;
Serial.println("http post " + String(requestUrl) + " code: " + httpResponseCode);
if (httpResponseCode == HTTP_CODE_OK){
String resp = httpClient.getString();
Serial.println("Send post success, resp " + String(resp));
}
else{
Serial.println("Send post request failed！");
}
httpClient.end();
}
void send_dingding_msg(String msg){
String body = "{\"msgtype\": \"text\",\"text\": {\"content\":\""+msg+"\"}}";
httpPostRequest(webhookUrl, body);
}
//Wifi init
void wifi_init(){
Serial.begin(9600);
WiFi.mode(WIFI_STA); //设置ESP8266为无线终端工作模式
WiFi.begin(ssid, password); //连接WiFi
Serial.println("");
Serial.println("Connecting"); Serial.println("");
// 等待连接
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
//成功连接后通过串口监视器显示WiFi名称以及ESP8266的IP地址。
Serial.println("");
Serial.print("Connected to ");
Serial.println(ssid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
}
void setup() {
pinMode(PIR_sensor, INPUT); //设置PIR模拟端口为输入模式
pinMode(LED, OUTPUT); //设置端口2为输出模式
wifi_init();
}
void loop() {
val = digitalRead(PIR_sensor); //读取A0口的电压值并赋值到val
//串口发送val值
delay(2000);
if (val == HIGH)//判断PIR数值是否大于150，
{
digitalWrite(LED,HIGH);//大于表示感应到有人
Serial.println("detect !!!!");
send_dingding_msg("告警：detect a human!");
}
else
{
digitalWrite(LED,LOW); //小于表示无感应到有人
}
