That's my code:
Code: Select all
#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
const char* ssid = "Casa";
const char* password = "micasa";
const char* host = "graph.facebook.com";
const char* url = "/v2.6/200630963285751?fields=fan_count&access_token=";
const char* token = "xxxxxxxxxxxxxxx";
const char* fingerprint = "CF 05 98 89 CA FF 8E D8 5E 5C E0 C2 E4 F7 E6 C3 C7 50 DD 5C";
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());
}
int value = 0;
void loop() {
delay(1000);
++value;
// Use WiFiClient class to create https connections
WiFiClientSecure client;
Serial.print("connecting to ");
Serial.println(host);
const int httpPort = 443;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");
return;
}
// We now create a URI for the request
// This will send the request to the server
String paquete = String("GET ") + url + token + " HTTP/1.1\r\n" + "Host:" + host + "\r\n\r\n";
Serial.println(paquete);
client.print(paquete);
delay(1000);
// Read all the lines of the reply from server and print them to Serial
while (client.available()) {
String line = client.readStringUntil('\r');
Serial.print(line);
}
Serial.println();
Serial.println("closing connection");
}
