Code for sending POST requests to the server via esp8266

The code:
WiFiClient client;
HTTPClient http;

Serial.print("[HTTP] begin...\n");
// configure traged server and url
http.begin(client, "http://" SERVER_IP "/postplain/"); // HTTP
http.addHeader("Content-Type", "application/json");

Serial.print("[HTTP] POST...\n");
// start connection and send HTTP header and body
int httpCode = http.POST("{"hello":"world"}");

// httpCode will be negative on error
if (httpCode > 0) {
// HTTP header has been send and Server response header has been handled
Serial.printf("[HTTP] POST... code: %d\n", httpCode);

// file found at server
if (httpCode == HTTP_CODE_OK) {
const String& payload = http.getString();
Serial.println("received payload:\n<<");
Serial.println(payload);
Serial.println(">>");
}
} else {
Serial.printf("[HTTP] POST... failed, error: %s\n", http.errorToString(httpCode).c_str());
}

http.end();
