angularjs - 离子2本机联系人插件查找不退出

Question

我正在尝试使用 ionic 2 native 查询所有联系人。运行 ionic serve 命令时出现以下错误。如果有人知道请告诉我，我该如何解决这个问题。谢谢

Typescript Error
Property 'find' does not exist on type 'typeof Contacts'.

主页.ts

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Contacts, Contact, ContactField, ContactName } from '@ionic-native/contacts';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  constructor(public navCtrl: NavController) {

  }
  testFun(){
    Contacts.find(['*']).then((contacts)=>{
      alert(JSON.stringify(contacts[0]));
    })
  }
}

主页.html

<ion-header>
    <ion-navbar>
        <ion-title>
            Ionic Blank
        </ion-title>
    </ion-navbar>
</ion-header>

<ion-content padding>
    <button ion-button full (click)="testFun()">Get Contacts</button>

从 Ionic 3.xx 开始，使用 Native 插件的方式与 Ionic 2.xx 略有不同

首先，您需要Contact在构造函数中添加
您需要Contact在 @Component中添加提供程序

所以你的home.ts应该是这样的：

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Contacts, Contact, ContactField, ContactName } from '@ionic-native/contacts';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html',
  providers: [Contacts]
})
export class HomePage {

  constructor(public navCtrl: NavController, private contacts: Contacts) {

  }

  testFun(){
    this.contacts.find(['*']).then((contacts)=>{
      alert(JSON.stringify(contacts[0]));
    })
  }
}

你试过这个吗？

Contacts.prototype.find(['*'])
            .then((contacts)=>{
                alert(JSON.stringify(contacts[0]));
            })
            .catch((err) => {
                alert('Error ' + err);
});
