How to fetch data from ThingHTTP using nodemcu v3(esp8266)?
using the ThingSpeak site in the ThingHTTP section, I receive data from one site, when checking the api, everything is fine, the data comes without errors, and now I need to receive the same data from this api and store it in a variable in nodemcu v3 (esp8266).
#include <ESP8266WiFi.h>
const char* ssid = "KBTU_wireless";
const char* password = "KBTUwireless!";
const char* host = "api.thingspeak.com";
void setup() {
Serial.begin(115200);
delay(10);
// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}//end setup
void loop() {
WiFiClient Client;
const int httpsPort = 80;
if (!Client.connect(host, httpsPort)) {
Serial.println("connection failed");
}
String url = "https://api.thingspeak.com/apps/thinghttp/send_request?api_key=967QSN6K892SR33T";
Client.print(String("GET ") + url + " HTTP/1.1\r\n" +
"Host: " + host = "\r\n" );
String line = Client.readStringUntil('\r');
Serial.println(line);
}
