Для выполнения вызовов HTTPS вам нужен клиент, который поддерживает SSL.Одним из примеров является httpsclient-particle
производства Glowfish, использующего matrixSSL.
Вы можете использовать его следующим образом:
// This #include statement was automatically added by the Particle IDE.
#include <httpsclient-particle.h>
static int anomalyLed = D7;
static int heartbeatLed = D7;
const bool g_https_trace = true; // This controls debug info print to Serial
const char host [] = "www.timeapi.org";
const char endpoint [] = "/utc/now/";
const int g_port = 443; // DoNOT change this unless you know what's up
static unsigned int freemem;
bool g_https_complete;
uint32 g_bytes_received;
TCPClient client;
unsigned char httpRequestContent[] = "GET %s HTTP/1.0\r\n"
"User-Agent: MatrixSSL/" MATRIXSSL_VERSION "\r\n"
"Host: www.timeapi.org\r\n"
"Accept: */*\r\n"
"Content-Type: application/json\r\n"
"Content-Length: %d\r\n\r\n%s";
void setup() {
if (g_https_trace) {
Serial.begin(9600);
}
pinMode(anomalyLed, OUTPUT);
httpsclientSetup(host, endpoint);
}
unsigned int nextTime = 0; // Next time to contact the server
int g_connected;
void loop() {
if (nextTime > millis()) return;
g_connected = client.connect(host, g_port);
if (!g_connected) {
client.stop();
// If TCP Client can't connect to host, exit here.
return;
}
g_https_complete = false;
g_bytes_received = 0;
if (g_https_trace) {
freemem = System.freeMemory();
Serial.print("free memory: ");
Serial.println(freemem);
}
int32 rc;
if ((rc = httpsClientConnection(httpRequestContent, 0, NULL) < 0)) {
// TODO: When massive FAIL
httpsclientCleanUp();
digitalWrite(anomalyLed, HIGH);
delay(500);
digitalWrite(anomalyLed, LOW);
delay(500);
digitalWrite(anomalyLed, HIGH);
delay(500);
digitalWrite(anomalyLed, LOW);
} else {
digitalWrite(heartbeatLed, HIGH);
delay(250);
digitalWrite(heartbeatLed, LOW);
}
client.stop();
nextTime = millis() + 5000;
}
