Build a Simple VCL Application for WooCommerce データ

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for WooCommerce, you gain access to live WooCommerce データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update WooCommerce データ. This article will walk through connecting to WooCommerce and creating a simple VCL application with the Form Designer.

Create a Connection to WooCommerce データ

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

WooCommerce は、one-legged OAuth1.0 認証と通常のOAuth2.0 認証をサポートします。

one-legged OAuth 1.0 認証を使って接続する

次のプロパティを指定してください（NOTE：次の資格情報はWooCommerce の設定ページで生成されるもので、WordPress OAuth2.0 プラグインで生成されるものとは異なります）。

• ConsumerKey
• ConsumerSecret

WordPress OAuth 2.0 認証を使って接続する

プラグインを設定した後、 次の接続プロパティを指定することでWooCommerce に接続できます。

• OAuthClientId
• OAuthClientSecret
• CallbackURL
• InitiateOAuth - GETANDREFRESH または REFRESH のどちらかに設定してください

どちらの場合方法でも、Url プロパティをWooCommerce インスタンスのURL に設定する必要があります。

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to WooCommerce データ.

1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
2. Right-click the ODBC Data Source node in the Data Explorer.
3. Click Add New Connection.
4. Enter a name for the connection.
5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for WooCommerce.

Create VCL Applications with Connectivity to WooCommerce データ

Follow the procedure below to start executing queries to WooCommerce データ from a simple VCL application that displays the results of a query in a grid.

1. Drop a TFDConnection component onto the form and set the following properties:

   • ConnectionDefName: Select the FireDAC connection to WooCommerce データ.
   • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.

2. Drop a TFDQuery component onto the form and set the properties below:

   • Connection: Set this property to the TFDConnection component, if this component is not already specified.

   • SQL: Click the button in the SQL property and enter a query. For example:

     SELECT ParentId, Total FROM Orders WHERE ParentId = '3'
   • Active: Set this property to true.

3. Drop a TDataSource component onto the form and set the following property:

   • DataSet: In the menu for this property, select the name of the TFDQuery component.

4. Drop a TDBGrid control onto the form and set the following property:

   • DataSource: Select the name of the TDataSource.
5. Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
