Connect to Apify Data in JRuby
JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Apify makes it easy to integrate connectivity to live Apify data in JRuby. This article shows how to create a simple JRuby app that connects to Apify data, executes a query, and displays the results.
Configure a JDBC Connection to Apify 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 Apify\lib).
JRuby natively supports JDBC, so you can easily connect to Apify 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 Apify Profile on disk (e.g. C:\profiles\Apify.apip). Next, set the ProfileSettings connection property to the connection string for Apify (see below).
Apify API Profile Settings
Obtain your API token from the Apify Console by navigating to Settings and generating a new API token.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Apify 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 Apify:
jdbc:api:Profile=C:\profiles\Apify.apip;ProfileSettings='APIKey=your_api_token';
Create a JRuby App with Connectivity to Apify 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 Apify 2018/lib/cdata.jdbc.api.jar'
url = "jdbc:api:Profile=C:\profiles\Apify.apip;ProfileSettings='APIKey=your_api_token';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, ActorId FROM ActorBuilds")
while (rs.next) do
puts rs.getString(1) + ' ' + rs.getString(2)
end
With the file completed, you are ready to display your Apify data with JRuby. To do so, simply run your file from the command line:
jruby -S APISelect.rb
