I found a solution HTTPS connection cryptocurrency monitoring


#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>

const char* ssid = "ASUS";
const char* password = "asus";

const char* host = "api.binance.com";
const int httpsPort = 443;

// Use web browser to view and copy
// SHA1 fingerprint of the certificate
const char* fingerprint = "5B:5F:CA:EA:D0:43:FC:52:2F:D9:E2:EC:A0:6C:A8:57:70:DB:58:F7";

void setup() {
  Serial.begin(115200);
  Serial.println();
  Serial.print("connecting to ");
  Serial.println(ssid);
  WiFi.mode(WIFI_STA);
  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());

  // Use WiFiClientSecure class to create TLS connection
  WiFiClientSecure client;
  Serial.print("connecting to ");
  Serial.println(host);
  if (!client.connect(host, httpsPort)) {
    Serial.println("connection failed");
    return;
  }

  if (client.verify(fingerprint, host)) {
    Serial.println("certificate matches");
  } else {
    Serial.println("certificate doesn't match");
  }

  String url = "/api/v1/ticker/price?symbol=ETHBUSD";
  Serial.print("requesting URL: ");
  Serial.println(url);

  client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" +
               "User-Agent: BuildFailureDetectorESP8266\r\n" +
               "Connection: close\r\n\r\n");

  Serial.println("request sent");
  while (client.connected()) {
    String line = client.readStringUntil('\n');
    if (line == "\r") {
      Serial.println("headers received");
      break;
    }
  }
  String line = client.readStringUntil('\n');
  
  Serial.println("reply was:");
  Serial.println("==========");
  Serial.println(line);
  Serial.println("==========");
  Serial.println("closing connection");
}

void loop() {
}

That's great.
So why did you post in "Installation and troubleshooting", and not in the "look what I done good" section?

I didn't see the category section it's now ok
