au Wowma ADO.NET Provider

在庫、商品、受注などのkau Wowma! データに連携する.NET アプリケーションを迅速に作成して配布できます。

This article shows how to publish an OData feed of au Wowma data by creating a WCF Service Application.

The CData ADO.NET Provider for au Wowma enables you to use the Windows Communication Foundation (WCF) framework to rapidly develop service-oriented applications that provide au Wowma data to OData consumers. This article shows how to create an entity data model to provide the underlying connectivity to the au Wowma 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 au Wowma 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 au Wowma Data Source and enter the necessary credentials. A typical connection string is below:

    au Wowma! へのアクセスの設定

    ShopId およびApiKey を取得するには、以下の手順に従ってください。

    • Wow! manager サイトにログインして、[各種お申し込み]メニューの[API利用申請]に移動します。
    • API利用規約に同意します。
    • [APIキーの発行はこちら]をクリックします。
    • [発行]ボタンをクリックして、API キーを生成します。
    • [接続元IPアドレスを登録]に、対象とするIP アドレスを入力します。
    • [登録]ボタンをクリックして、設定を保存します。

    au Wowma! アカウントの認証


    • ShopId:接続先のau Wowma! Shop ID を設定。
    • ApiKey:API キーを設定。au Wowma! ストアアカウントから取得したAPI キーです。
    • UseSandbox:Sandbox 環境に接続する場合はTrue を設定。

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

  7. Select au Wowma 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 WowmaService{ public class WowmaDataService : 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/WowmaDataService.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.
