可以使用Arduino PORTENTA机器控制板来使用HTTPS和SSE客户端库。下面是使用ArduinoHttpClient和ArduinoSSEWiFiclient库的示例代码：

#include #include

const char* host = "your-host-name.com"; const int httpsPort = 443; const char* path = "your-path";

WiFiClientSecure wifiClient; HttpClient httpsClient = HttpClient(wifiClient, host, httpsPort);

SSEClient sseClient(wifiClient, "https://push.your-host-name.com");

void setup() { Serial.begin(9600); WiFi.begin("your-network-name", "your-network-password"); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting to WiFi..."); } Serial.println("Connected to WiFi");

wifiClient.setCACert(root_ca); wifiClient.setTimeout(15000);

Serial.println("Making HTTPS request..."); httpsClient.beginRequest(); httpsClient.get(path); httpsClient.sendHeader("Host", host); httpsClient.endRequest();

Serial.print("Response: "); Serial.println(httpsClient.getResponseStatusCode()); Serial.println(httpsClient.getResponseBody()); httpsClient.stop();

Serial.println("Connecting to SSE server..."); sseClient.connect(); }

void loop() { if (sseClient.connected()) { while (sseClient.available()) { Serial.println(sseClient.readString()); } } else { Serial.println("Disconnected from SSE server. Reconnecting..."); sseClient.connect(); } }
