nodeMCU connect refused with XMAPP localhost - xampp

Question

My project is about using nodeMCU measure value from sensor DHT11 and sent value to database Mysql. I use xampp for server. I cannot sent value to database.
nodeMCU can read value and sent value.But HTTP GET is fail.And return connect refused. I think maybe have problems with port for listening.
this is my code
#include <Arduino.h>
#include <ESP8266HTTPClient.h>
#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>
#include "DHT.h"
#define DHTPIN 2 // what digital pin the DHT22 is conected to
#define DHTTYPE DHT11 // there are multiple kinds of DHT sensors
DHT dht(DHTPIN, DHTTYPE);
ESP8266WiFiMulti WiFiMulti;
const char* ssid = "something";
const char* password = "something";
int EP =5;
void setup() {
Serial.begin(115200);
pinMode(EP, INPUT);
for (uint8_t t = 4; t > 0; t--) {
Serial.printf("[SETUP] WAIT %d...\n", t);
Serial.flush();
delay(1000);
}
WiFiMulti.addAP(ssid, password); // ssid , password
randomSeed(50);
}
int timeSinceLastRead = 0;
void loop() {
if ((WiFiMulti.run() == WL_CONNECTED)) {
HTTPClient http;
float temp = dht.readTemperature();
float humi = dht.readHumidity();
long meas =TP_init();
Serial.println(WiFi.localIP());
//int temp = random(25,35);
String url = "localhost:8012/add2.php?temp="+String(temp)+"&humi="+String(humi)+"&meas=0";
Serial.println(url);
http.begin(url); //HTTP
int httpCode = http.GET();
if (httpCode > 0) {
Serial.printf("[HTTP] GET... code: %d\n", httpCode);
if (httpCode == HTTP_CODE_OK) {
String payload = http.getString();
Serial.println(payload);
}
} else {
Serial.printf("[HTTP] GET... failed, error: %s\n", http.errorToString(httpCode).c_str());
}
http.end();
}
delay(3000);
}
long TP_init(){
delay(10);
long meas=pulseIn (EP, HIGH); //wait for the pin to get HIGH and returns measurement
return meas;
}
I changed Apache port from 80 to 8012
I use PHPMyadmin for store database . File php's name add2.php for insert value from sensor DHT11
enter image description here
This is result from serial port.

String url = "localhost should be replaced with String url = "<IP-address-of-your-webserver> as the webserver clearly isn't running on the ESP8266.
