JRuby からBigCommerce Data にデータ連携

リアルタイムBigCommerce data に連携するシンプルなJRuby アプリケーションを作成します。

JRuby はRuby プログラミング言語の高性能で安定した、完全にスレッド化されたJava 実装です。CData JDBC Driver for BigCommerce を使用すると、JRuby からリアルタイムBigCommerce data へのデータ連携を簡単に実装できます。ここでは、BigCommerce data に接続し、クエリを実行して結果を表示する簡単なJRuby アプリを作成する方法を説明します。

BigCommerce Data にJDBC で接続

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CDatat\CData JDBC Driver for BigCommerce\lib).

JRuby natively supports JDBC, so you can easily connect to BigCommerce and execute SQL queries.Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

BigCommerce authentication is based on the standard OAuth flow. To authenticate, you must initially create an app via the Big Commerce developer platform where you can obtain an OAuthClientId, OAuthClientSecret, and CallbackURL. These three parameters will be set as connection properties to your driver.

Additionally, in order to connect to your BigCommerce Store, you will need your StoreId. To find your Store Id please follow these steps:

  1. Log in to your BigCommerce account.
  2. From the Home Page, select Advanced Settings > API Accounts.
  3. Click Create API Account.
  4. A text box named API Path will appear on your screen.
  5. Inside you can see a URL of the following structure: https://api.bigcommerce.com/stores/{Store Id}/v3.
  6. As demonstrated above, your Store Id will be between the 'stores/' and '/v3' path paramters.
  7. Once you have retrieved your Store Id you can either click Cancel or proceed in creating an API Account in case you do not have one already.

For assistance in constructing the JDBC URL, use the connection string designer built into the BigCommerce JDBC Driver.Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.bigcommerce.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for BigCommerce:

jdbc:bigcommerce:OAuthClientId=YourClientId; OAuthClientSecret=YourClientSecret; StoreId='YourStoreID'; CallbackURL='http://localhost:33333'InitiateOAuth=GETANDREFRESH

BigCommerce Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: BigCommerceSelect.rb) and open it in a text editor.Copy the following code into your file:

require 'java' require 'rubygems' require 'C:/Program Files/CData/CData JDBC Driver for BigCommerce 2018/lib/cdata.jdbc.bigcommerce.jar' url = "jdbc:bigcommerce:OAuthClientId=YourClientId; OAuthClientSecret=YourClientSecret; StoreId='YourStoreID'; CallbackURL='http://localhost:33333'InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT FirstName, LastName FROM Customers") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

With the file completed, you are ready to display your BigCommerce data with JRuby.To do so, simply run your file from the command line:

jruby -S BigCommerceSelect.rb
