Provide OData Services of Ponparemall Data from a WCF Application

The CData ADO.NET Provider for Ponparemall enables you to use the Windows Communication Foundation (WCF) framework to rapidly develop service-oriented applications that provide Ponparemall data to OData consumers. This article shows how to create an entity data model to provide the underlying connectivity to the Ponparemall data, as well as how to create a WCF Data Service to expose the OData service. You can then consume the feed with any OData client, for example, Power Pivot or an application that uses the CData ADO.NET Provider for OData.

Create the OData Service

Follow the steps below to create a WCF service application that will provide connectivity to Ponparemall data via OData.

1. Open Visual Studio and create a new project. Select the WCF Service Application template.
2. Delete the autogenerated IService.cs and Service1.svc.
3. Click Project -> Add New Item -> ADO.NET Entity Data Model.
4. In the Entity Data Model wizard that is displayed, select the 'EF Designer from Database' option.
5. In the resulting Choose Your Connection dialog, click New Connection.

6. In the Connection properties dialog, select the CData Ponparemall Data Source and enter the necessary credentials. A typical connection string is below:

   InventoryUserId=Inventory UserId;InventoryPassword=Invetory Password;

   Ponparemall に接続するには、ShopUrl、InventoryUserId、InventoryPassword、OrderUserId、OrderPassword、PaymentUserId、およびPaymentPassword が必要です。

   Ponparemall へのアクセスの設定

   Ponparemall には各API のId とPassword が必要です。取得するには、以下の手順に従ってください。

   • Ponparemall Manager にログインし、メニューの「各種申請」の「WebAPI利用申請」をクリックします。
   • Web API メニューの「WebAPIサービス利用申請」をクリックし、利用申請を行います。
   • 後日、Ponparemall から必要なId とPassword が送られてきます。

   Ponparemall アカウントの認証

   次の接続プロパティを設定して接続します。

   • ShopUrl：接続先のPonparemall Shop URL を設定。「http://storetst4.ponparemall.com/sample/」に含まれる「sample」の部分を入力します。
   • InventoryUserId：「在庫API」のユーザID を設定。このプロパティは、Inventory テーブルにアクセスする場合に必要です。
   • InventoryPassword：「在庫API」のパスワードを設定。このプロパティは、Inventory テーブルにアクセスする場合に必要です。
   • OrderUserId：「受注API」のユーザID を設定。このプロパティは、Orders テーブルにアクセスする場合に必要です。
   • OrderPassword：「受注API」のパスワードを設定。このプロパティは、Orders テーブルにアクセスする場合に必要です。
   • PaymentUserId：「決済API」のユーザID を設定。このプロパティは、Payments テーブルにアクセスする場合に必要です。
   • PaymentPassword：「決済API」のパスワードを設定。このプロパティは、Payments テーブルにアクセスする場合に必要です。

   See the help documentation for guides to connecting in Visual Studio.

7. Select Ponparemall tables and views that you want OData clients to access.
8. Click Project -> Add New Item -> WCF Data Service.

9. Specify the data source class and configure access to the new WCF Data Service. In the example below, the Access Rule for the entities is set to All. This means that any user will be able to read and modify data.

   using System; using System.Collections.Generic; using System.Data.Services; using System.Data.Services.Common; using System.Linq; using System.ServiceModel.Web; using System.Web; namespace PonparemallService{ public class PonparemallDataService : DataService { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3; } } }
10. Run the project. Applications that support OData can now access the Salesforce data and reflect any changes. You can access the feed in your browser. The feed will resemble the following:

Consume the OData Service from Power Pivot

You can now use the service from any OData client; for example, Excel Power Pivot.

1. Open Excel and click on the Power Pivot Window button.
2. A new pop-up will appear. Select the option From Data Feeds.
3. In the resulting Table Import Wizard, enter the OData URL. For example, http://localhost:12449/PonparemallDataService.svc/.
4. After connecting to the OData service, click the Next button at the bottom of the window.
5. A table listing of the available tables will appear in the next window of the wizard. Select which tables you want to import and click Finish.
6. Click Close to import the data in Power Pivot.
