Ionic 2 HTTP.post not send data

Question

I has a problem, When I post data to my api server.

My api server didn't get any data, It send from ionic app.

This is my api providers.

import { Injectable } from '@angular/core';
import { HTTP } from 'ionic-native';
import 'rxjs/add/operator/map';


@Injectable()
export class APIProvider {

  constructor() {}

  getProduct(){
    return new Promise(resolve => {
      let header = {"Content-Type": "application/json"}

      let body = {
        "data_1": "1234567890123",
        "data_2": "125615"
      }

      HTTP.post('https://ex.com/api/somethig', JSON.stringify(body), header)
      .then(data => {
        console.log(data.status);
        console.log(data.data); // data received by server
        console.log(data.headers);
        resolve(data);
      })
      .catch(error => {
        console.log(error.status);
        console.log(error.error); // error message as string
        console.log(error.headers);
        resolve(error);
      });
    });
  }
}

In api server (PHP), I try vardump($_POST);/ But it return array(0) {}

Console log

[15:20:15]  console.log: 200 
[15:20:15]  console.log: array(0) { } 
[15:20:15]  console.log: [object Object]

Ahhhh, I found the answer.

Just changed "Content-Type": "application/json" to "Content-Type": "application/x-www-form-urlencoded".
