my page.ts
import { Component } from '#angular/core';
import { NavController } from 'ionic-angular';
import { Http } from '#angular/http';
import "rxjs/add/operator/map"
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
list_car:any;
constructor(public navCtrl: NavController, public http: Http) {
//check if the omra section exist or not
this.http.get("http://android.page.com/2omra_details.php")
.map(res
=> res.json().omra)
.subscribe(data => {
this.list_car = data;
console.log(this.list_car);
})
}
}
Any suggestions to what I may be doing wrong?

Your endpoint not working
Try with sample data API example
import { Injectable } from '#angular/core';
import { HttpClient } from '#angular/common/http';
import { Observable } from "rxjs/Observable";
import 'rxjs/add/operator/retry';
#Injectable()
export class ApiService {
url: string = 'https://api.chucknorris.io/jokes/random';
url2: string = 'https://api.spacexdata.com/v2/launches/latest';
constructor(private http: HttpClient) {}
getData(): Observable<ApiResponse> {
return this.http.get<ApiResponse>(this.url).retry(3);
}
getOtherData(): Observable<any> {
return this.http.get<any>(this.url2).retry(3);
}
}
export interface ApiResponse {
icon_url: string;
id: string;
url: string;
value: string;
