android http请求在android设备或android模拟器上不起作用

Question

所以我刚刚创建了这个离子应用程序，我在上面放了一个http请求方法用于测试，问题是我为android构建了这个应用程序http方法不起作用。但它工作得很好，为iOS赢得了一个构建它，

这是我的离子信息：

  ionic (Ionic CLI)  : 4.6.0 (/Users/us/node_modules/ionic)
   Ionic Framework    : ionic-angular 3.9.5
   @ionic/app-scripts : 3.2.2

   Cordova:

   cordova (Cordova CLI) : 9.0.0 (cordova-lib@9.0.1)
   Cordova Platforms     : android 8.0.0, ios 5.0.1
   Cordova Plugins       : cordova-plugin-ionic 5.3.1, cordova-plugin- 
   ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 4.1.1, (and 6 
   other plugins)

系统：

 ios-sim : 8.0.1
   NodeJS  : v10.15.1 (/usr/local/bin/node)
   npm     : 6.9.0
   OS      : macOS High Sierra
   Xcode   : Xcode 10.1 Build version 10B61

我的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); 


})

}

}

对我可能做错了什么有什么建议吗？

您的终结点不工作

尝试使用示例数据接口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;
