Connect to Scrapfly Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for Scrapfly into your processes in RapidMiner. This article uses the CData JDBC Driver for Scrapfly to transfer Scrapfly data to a process in RapidMiner.

Connect to Scrapfly in RapidMiner as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Scrapfly:

1. Add a new database driver for Scrapfly: Click Connections -> Manage Database Drivers.
2. In the resulting wizard, click the Add button and enter a name for the connection.
3. Enter the prefix for the JDBC URL:

   jdbc:api:
   

4. Enter the path to the cdata.jdbc.api.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class:

   cdata.jdbc.api.APIDriver
   

   
6. Create a new Scrapfly connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Scrapfly driver you configured previously.
9. Enter your connection string in the Host box.

   The Scrapfly API uses API Key authentication. The API key is passed as the key query parameter on every request.

   Using API Key Authentication

   Your Scrapfly API key is required to create a connection. To obtain your API key:

   1. Log into your Scrapfly account at scrapfly.io.
   2. Navigate to Dashboard and select API Keys.
   3. Copy your API key (begins with scp-live- for production or scp-test- for the test environment).

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Scrapfly API key.

   Example connection string:

   Profile=C:\profiles\Scrapfly.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';
   

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Scrapfly 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.

   

   A typical connection string is below:

   Profile=C:\profiles\Scrapfly.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';
   

10. Enter your username and password if necessary.

You can now use your Scrapfly connection with the various RapidMiner operators in your process. To retrieve Scrapfly data, drag the Retrieve operator from the Operators view. With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the Scrapfly data.
