Query Spotify Data in ColdFusion

The CData JDBC driver for Spotify seamlessly integrates connectivity to Spotify data with the rapid development tools in ColdFusion. This article shows how to connect to Spotify data in ColdFusion and query Spotify tables.

Create a JDBC Data Source for Spotify in ColdFusion

The JDBC data source enables you to execute SQL from standard ColdFusion tags like cfquery and CFScript like executeQuery.

1. Copy the driver JAR and .lic file from the installation directory onto the ColdFusion classpath. For example, copy the files into C:\MyColdFusionDirectory\cfusion\wwwroot\WEB-INF\lib. Or, open the Java and JVM page in the ColdFusion Administrator and enter the path to the files in the ColdFusion Class Path box.

   The JAR and license for the driver are located in the lib subfolder of the installation directory.

   Restart the server after this step.

2. Add the driver as a data source:

   From the ColdFusion administrator interface, expand the Data & Services node and click Data Sources. In the Add New Data Source section, enter a name for the data source and select Other in the Driver menu.

   

3. Populate the driver properties:

   • JDBC URL: Enter connection properties in the JDBC URL. The JDBC URL begins with jdbc:api: and is followed by the connection properties in a semicolon-separated list of name=value pairs.

     Using OAuth Authentication

     Spotify uses OAuth 2.0 for authentication. You will need to create an application in the Spotify Developer Dashboard to obtain your client credentials.

     Setting Up Your Spotify Application

     1. Visit the Spotify Developer Dashboard.
     2. Log in with your Spotify account and click Create app.
     3. Provide an app name, description, and set a Redirect URI (e.g.,

        http://localhost:33333

        for desktop applications).
     4. Copy your Client ID and Client Secret from the app settings.

     Connection Properties

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

     • AuthScheme: Set this to OAuth.
     • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
     • OAuthClientId: Set this to your Spotify application's Client ID.
     • OAuthClientSecret: Set this to your Spotify application's Client Secret.
     • Scope: Set this to the required OAuth scopes (space-separated). The default includes all read scopes needed for the tables in this profile.
     • CallbackURL: Set this to the Redirect URI configured in your Spotify application (e.g., http://localhost:33333).

     Example Connection String

     Profile=C:\profiles\Spotify.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;
     

     Available OAuth Scopes

     • user-read-private: Read access to user's subscription details and explicit content settings.
     • user-read-email: Read access to user's email address.
     • user-library-read: Read access to a user's saved tracks, albums, episodes, shows, and audiobooks.
     • playlist-read-private: Read access to user's private playlists.
     • playlist-read-collaborative: Read access to collaborative playlists the user follows.
     • user-follow-read: Read access to the list of artists the current user follows.
     • user-read-playback-state: Read access to a user's player state (device, current track, progress).
     • user-read-currently-playing: Read access to a user's currently playing content.
     • user-read-playback-history: Read access to a user's recently played tracks.
     • user-top-read: Read access to a user's top artists and tracks.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Spotify 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 JDBC URL is below:

     jdbc:api:Profile=C:\profiles\Spotify.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;

   • Driver Class: Enter the driver class. The driver class is cdata.jdbc.api.APIDriver.
   • Driver Name: Enter a user-defined name for the driver.
   • Username: Enter the username used to authenticate.
   • Password: Enter the password used to authenticate.

You can now test the connection by enabling the CData Spotify data source in the Actions column. After reporting a status of OK, the Spotify data source is ready for use.

Execute Queries

The cfquery tag can pass SQL statements to Spotify. Use the cfqueryparam tag to create parameterized queries and prevent SQL injection through the query string.

Note: To use the cfquery and cfscript, create a .cfm file. Inside the .cfm file, write the code to execute the query (see below). Place the file directly in the root directory of your web server (e.g., wwwroot in Adobe ColdFusion). Restart the service after placing the file for the changes to take effect.

<cfquery name="APIQuery" dataSource="CDataAPI">
  SELECT * FROM Albums WHERE Id = <cfqueryparam value="#Id#" cfsqltype="cf_sql_varchar">
</cfquery>
<cfdump var="#APIQuery#">

Below is the equivalent in CFScript:

<cfscript>
result = queryExecute(
  "SELECT * FROM Albums WHERE Id = ?", 
  [
    { value="4aawyAB9vmqN3uQ7FjRGTy", cfsqltype="cf_sql_varchar" }
  ],
  { datasource="CDataAPI" }
);

writeDump( var= result );
</cfscript> 

You can then make requests to your .cfm like the following:

http://MyServer:8500/query.cfm?Id=4aawyAB9vmqN3uQ7FjRGTy
