Connect to Pushover Data in JRuby

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Pushover makes it easy to integrate connectivity to live Pushover data in JRuby. This article shows how to create a simple JRuby app that connects to Pushover data, executes a query, and displays the results.

Configure a JDBC Connection to Pushover Data

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

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

Start by setting the Profile connection property to the location of the Pushover Profile on disk (e.g. C:\profiles\Pushover.apip). Next, set the ProfileSettings connection property to the connection string for Pushover (see below).

Pushover API Profile Settings

Pushover uses API Key authentication. Your Pushover Application API Token is used to authenticate all requests. You can create and manage API tokens in the Pushover dashboard at pushover.net by registering an application under Settings > Your Applications.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your 30-character Pushover Application API Token.

Built-in Connection String Designer

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

java -jar cdata.jdbc.api.jar

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

Below is a typical JDBC connection string for Pushover:

jdbc:api:Profile=C:\profiles\Pushover.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_application_token';

Create a JRuby App with Connectivity to Pushover Data

Create a new Ruby file (for example: APISelect.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 Pushover 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\Pushover.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_application_token';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT User, Memo FROM GroupMembers")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S APISelect.rb
