小编Ber*_* K.的帖子

我是Ionic的新手.

我能够使用IONIC Storage Service存储A JSON对象(数据); 但是,当我尝试检索JSON数据时,我得到了未定义.

我感谢任何帮助 - 下面是我的代码:

Provider:storage-service.ts:我能够存储和输出数据,但是我无法返回数据:

import {Injectable} from '@angular/core';
import { Storage } from '@ionic/storage';

@Injectable()
export class StorageService {

constructor(public storage: Storage){}

public storeData (data) {
    this.storage.set('data', data);
}

public getStoredData() {
         this.storage.get('data').then((val) => {
        console.dir(val);  //****** this outputs the object.
        return val;  //***** this returns undefined
        });
  }
 }

我-page.ts:

import {StorageService} from "../../providers/storage-service";

constructor(public storageService: StorageService) {

    //***** this outputs undefined, what I'm doing wrong?
    console.dir(this.storageService.getStoredData());
}

非常感谢任何帮助.

谢谢
