私のアプリケーションの動作ではありません上記のコードで問題ありません。今私はアプリケーションにセッションストレージを追加したいので、私はNg2Webstorage（v1.5）を使用しました。 NPMを使ってインストールしました。できるだけ早く私は、次のコードを追加、よう：

添加すると、私は次のエラーを受信を開始

map:{ 
...... 
...... 
'ng2-webstorage' : 'npm:ng2-webstorage' 
} 

packages:{ 
.... 
.... 
, 
     'ng2-webstorage': { 
     main: 'bundles/core.umd.js', 
     defaultExtension: 'js' 
     } 
} 

systemjs.config.jsする

import {Ng2Webstorage}      from 'ng2-webstorage'; 
... 
... 
@NgModule({ 
    imports:  [ 
     ... 
    ,.... 
    , Ng2Webstorage 
], 
    ... 
}) 

追加をapp.module.tsします。私はNg2Webstorageを削除しようとし、私のアプリは正常に動作します。

をセッションストレージの使用中のキーtokenでabdheajskkeトークン値を設定するには：token値を取得するには

sessionStorage.setItem("token", "abdheajskke") 

あなたが直接、以下のようにsessionStorageのsetItem、getItemとclearメソッドを使用することができます

Answer 1

セッションストレージからの使用：

sessionStorage.getItem("token") 

sessionStorageを使用する独自のサービスを作成することもできます。以下は、あなたが使用できる単純な最小限のサービスの例です：

import { Injectable } from '@angular/core'; 

@Injectable() 
export class StorageService { 

    public setItem(key: string, data: any) { 
    sessionStorage.setItem(key, JSON.stringify(data)); 
    } 

    public getItem(key: string) { 
    if (!!sessionStorage.getItem(key)) { 
     return sessionStorage.getItem(JSON.parse(key));   
    } else { 
     return false; 
    } 
    } 

    public clear() { 
    sessionStorage.clear(); 
    return true; 
    } 

    public removeItem(key: string) { 
    sessionStorage.removeItem(key); 
    return true; 
    } 
}
