I have build some code like this but still sent got nothing.

anyone can help me?
thank you very much regards

#include <WiFi.h>
#include <HTTPClient.h>

const char* ssid = "asdasd";
const char* password = "asdasd";

const char* serverName = "http://192.168.0.120:8087/";
unsigned long lastTime = 0;

unsigned long timerDelay = 2000;

void setup() {
  Serial.begin(115200);

  WiFi.begin(ssid, password);
  Serial.println("Connecting");
  while(WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.print("Connected to WiFi network with IP Address: ");
  Serial.println(WiFi.localIP());
 
  Serial.println("Timer set to 5 seconds (timerDelay variable), it will take 5 seconds before publishing the first reading.");
}

void loop() {

  if ((millis() - lastTime) > timerDelay) {

    if(WiFi.status()== WL_CONNECTED){
      HTTPClient http;

      http.begin(serverName);

   http.addHeader("Content-Type", "text/plain");
      int httpResponseCode = http.POST("/set/try_simple_api2?value=7");
     
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
        
      // Free resources
      http.end();
    }
    else {
      Serial.println("WiFi Disconnected");
    }
    lastTime = millis();
  }
}
