Http post digitalread state as text

[invidia81]

Hello,

I have following working well:

 // Prepare your HTTP POST request data
  String httpRequestData = "api_key=" + apiKeyValue + "&cb_serial=" + serial + "&temp=" + String(sensors.getTempCByIndex(0)) + "&sump=" + String(digitalRead(FLOAT_SENSOR)) + "";

String(digitalRead(FLOAT_SENSOR) now gives me output 0 or 1 (writes it to mysql database).

I would like to give me when 0 some text and when 1 some other text.
How to accomplish ?
Thanks.

You could use the ternary operator.

Please remember to use code tags when posting code

Something like this ? No way of doing this shorter ?

HTTPClient http;
  // Your Domain name with URL path or IP address with path
  http.begin(client, serverName);
    
  // Specify content-type header
  http.addHeader("Content-Type", "application/x-www-form-urlencoded");

  if (digitalRead(FLOAT_SENSOR) == LOW) {
  // Prepare your HTTP POST request data
  String httpRequestData = "api_key=" + apiKeyValue + "&cb_serial=" + serial + "&temp=" + String(sensors.getTempCByIndex(0)) + "&sump=" + "Low" + "";

  // Send HTTP POST request
  int httpResponseCode = http.POST(httpRequestData);
 
   if (httpResponseCode>0) {
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
    }
    else {
      Serial.print("Error code: ");
      Serial.println(httpResponseCode);
    }
    // Free resources
    http.end();
  }
  else {
    // Prepare your HTTP POST request data
  String httpRequestData = "api_key=" + apiKeyValue + "&cb_serial=" + serial + "&temp=" + String(sensors.getTempCByIndex(0)) + "&sump=" + "Ok" + "";

  // Send HTTP POST request
  int httpResponseCode = http.POST(httpRequestData);
 
   if (httpResponseCode>0) {
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
    }
    else {
      Serial.print("Error code: ");
      Serial.println(httpResponseCode);
    }
    // Free resources
    http.end();
  }

You certainly do not have to repeat everything twice, only the part that changes which is "Low" vs. "Ok"

HTTPClient http;
// Your Domain name with URL path or IP address with path
http.begin(client, serverName);
String sensor_msg;

// Specify content-type header
http.addHeader("Content-Type", "application/x-www-form-urlencoded");

if (digitalRead(FLOAT_SENSOR) == LOW) {
  sensor_msg = "Low";
}
else {
  sensor_msg = "Ok";
}
// Prepare your HTTP POST request data
String httpRequestData = "api_key=" + apiKeyValue + "&cb_serial=" + serial + "&temp=" + String(sensors.getTempCByIndex(0)) + "&sump=" + sensor_msg;

// Send HTTP POST request
int httpResponseCode = http.POST(httpRequestData);

if (httpResponseCode > 0) {
  Serial.print("HTTP Response code: ");
  Serial.println(httpResponseCode);
}
else {
  Serial.print("Error code: ");
  Serial.println(httpResponseCode);
}
// Free resources
http.end();
}
