Bonjour à tous,

Je tente d'accéder à des données d'une bdd MySQL depuis IONIC 3 et je n'arrive pas à afficher les données JSON retournées.

Voici l'erreur que j'ai : ERROR SyntaxError: Unexpected end of JSON input

Fichier.ts:

import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams, AlertController } from 'ionic-angular';
import { Headers, RequestOptions, Http}  from "@angular/http";
import { LoadingController } from 'ionic-angular';


import { HomeService } from '../../services/home-service';
import { IService } from '../../services/IService';

import { DetailPage } from '../detail/detail';


@IonicPage()
@Component({
  selector: 'page-liste',
  templateUrl: 'liste.html',
  providers: [HomeService],
})

export class ListePage {

   public items : Array<any> = [];

  constructor(public navCtrl: NavController, public navParams: NavParams, public alertCtrl: AlertController, public http : Http, public loading: LoadingController, public service:HomeService) {
  }

  ionViewWillEnter() : void
  {
    this.load();
  }


  load() : void
  {
    let loader = this.loading.create({
      content: 'Recherche des offres',
    });  
    loader.present().then(() => {
      this.http.post('https://mon.url.com/offres-liste.php').map(res => res.json()).subscribe(res => {
        console.log(res)
        loader.dismiss()
        if(res == "Pas d'enregistrements"){
          let alert = this.alertCtrl.create({
            title: "Désolé",
            subTitle: (res),
            buttons: ['OK']
          });
          alert.present();
        } else {
          console.dir(res);
         this.items = res;
        }
      });
    });
  }  

Le fichier PHP qui doit me retourner les données :

<?php
	if (isset($_SERVER['HTTP_ORIGIN'])) {
		header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
		header('Access-Control-Allow-Credentials: true');
		header('Access-Control-Max-Age: 86400');    // cache for 1 day
	}
	
	// Access-Control headers are received during OPTIONS requests
	
	if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
		if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
			header('Access-Control-Allow-Methods: GET, POST, OPTIONS');        
		if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
			header("Access-Control-Allow-Headers:{$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
		exit(0);
	}

	require 'dbconnect.php';
	$data    = array();
	
	
	$sql = "SELECT id, titre, description  FROM offre ORDER BY id ASC";
	

	$result = mysqli_query($con,$sql);
	$count = mysqli_num_rows($result);
	
	//$row = mysqli_fetch_array($result, MYSQLI_ASSOC);
	
	while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
		// Assign each row of data to associative array
		$data[] = $row;
	}

                      
	if($count > 0) {
		$response = $data;
	} else {
		$response = "Pas d'enregistrements";         
	}
	
	echo json_encode($response);
		


?>

Merci de votre aide !
