离线功能未在警报

Question

我有一个正在使用浏览器的删除功能，但当我ionic upload并在我的手机上试用它时，它甚至都没有运行它

showConfirm(index) {
let confirm = this.alertCtrl.create({
  title: 'Delete Lay Minister',
  message: 'Are you sure you want to delete this lay minister?',
  buttons: [
    {
      text: 'Disagree',
      handler: () => {
      }
    },
    {
      text: 'Agree',
      handler: () => {
        this.doDelete(index);
      }
    }
  ]
});
confirm.present();
}

这是删除功能，根本不运行，但警报将运行

doDelete(index){
    let id = this.layMinisters[index].id;
    this.layMinisterProvider.deleteLayMinister(id).subscribe(
      res => {
        this.presentToast();
        this.layMinisters.splice(index, 1);
     }
    );
}

修改::

Lay Minister Provider

deleteLayMinister(id): Observable<any>{
    return this.http.delete(
      this.api.url() + '/faith-leader/' + 'lay-minister/' + id + '/delete',
      {
        headers: new Headers({ "Authorization": "Bearer " + this.access_token })        
      }
    );
}
