Send POST Request with custom JSON - MKR1000

Hi! I have to send a POST request with this JSON:

json.prettyPrintTo(Serial); /* { "username": "user", "password": "pass, "inputs": [ { "name": "round", "value": 6 }, { "name": "light", "value": 15 }, { "name": "temperature", "value": 70.60547 } ] } */

json.printTo(Serial); // {"username":"user","password":"pass","inputs":[{"name":"round","value":1},{"name":"light","value":16},{"name":"temperature","value":73.53516}]}

Using POSTMAN I must add the following fields:

In Headers section, Content-Type = application/json In Body section, I select raw, and JSON (application/json)

This works fine. But in Arduino, i dont know if my code is correct, it doesn't work: (I could send an email, so the problem isn't with the wifi conection)

//************************************************************************ // POST REQUEST //************************************************************************

void post(float temp, int light, int count) { WiFiClient client; String httpsRequest = "https://mydomain.com"; const char* host = "mydomain.com";

// CONVERT VALUES TO STRING String tempS = String(temp); String lightS = String(light); String countS = String(count); String jsonS = "{(\"username\":\"user\",\"password\":\"pass\"}";

if (client.connect(host, 922)) { Serial.println("Connected to client"); client.println("POST http://mydomain.com:port/blablabla HTTP/2.0"); client.println("Host: mydomain.com"); client.println("Connection: close"); client.println("Content-Type: application/json"); client.println(jsonS);

delay(2000);

while (client.available()) { // Print on the console the answer of the server char c = client.read(); Serial.write(c); } client.stop(); // Disconnect from the server } else { Serial.println("Failed to connect to client"); } }

Any ideas?
