JRuby からPayPal Data にデータ連携

リアルタイムPayPal 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 PayPal を使用すると、JRuby からリアルタイムPayPal data へのデータ連携を簡単に実装できます。ここでは、PayPal 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。

PayPal 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 PayPal\lib).

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

The provider surfaces tables from two PayPal APIs. The APIs use different authentication methods.

  • The REST API uses the OAuth standard. To authenticate to the REST API, you will need to set the OAuthClientId, OAuthClientSecret, and CallbackURL properties.
  • The Classic API requires Signature API credentials. To authenticate to the Classic API, you will need to obtain an API username, password, and signature.

See the "Getting Started" chapter of the help documentation for a guide to obtaining the necessary API credentials.

To select the API you want to work with, you can set the Schema property to REST or SOAP. By default the SOAP schema will be used.

For testing purposes you can set UseSandbox to true and use sandbox credentials.

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

java -jar cdata.jdbc.paypal.jar

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

Below is a typical JDBC connection string for PayPal:

jdbc:paypal:Schema=SOAP;Username=sandbox-facilitator_api1.test.com;Password=xyz123;Signature=zx2127;InitiateOAuth=GETANDREFRESH

PayPal Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: PayPalSelect.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 PayPal 2018/lib/cdata.jdbc.paypal.jar' url = "jdbc:paypal:Schema=SOAP;Username=sandbox-facilitator_api1.test.com;Password=xyz123;Signature=zx2127;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Date, GrossAmount FROM Transactions") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S PayPalSelect.rb

Writing SQL-92 queries to PayPal allows you to quickly and easily incorporate PayPal data into your own JRuby applications.Download a free trial today!
