How to Integrate Microsoft Azure Cognitive Services with Drupal

January 24, 2025

Discover a step-by-step guide to integrating Microsoft Azure Cognitive Services into your Drupal site effortlessly and enhance its capabilities.

How to Connect Microsoft Azure Cognitive Services to Drupal: a Simple Guide

 

Prerequisites

 

  • Ensure you have a Microsoft Azure account and have set up an instance of Cognitive Services.
  •  

  • Have a running Drupal site (preferably Drupal 9 or higher) with admin rights.
  •  

  • Familiarity with Composer and Drush, which are required for module management in Drupal.
  •  

  • Access to the terminal or command line interface on your server or development environment.

 

Install Microsoft Azure SDK for PHP

 

  • Use Composer to install the Microsoft Azure SDK, which is required to connect with Azure Cognitive Services:

 

composer require microsoft/azure-storage-blob-php

 

  • Add the installed package to your autoload.php if it hasn't been automatically included:

 

require 'vendor/autoload.php';
use MicrosoftAzure\Storage\Blob\BlobRestProxy;

 

Enable Required Drupal Modules

 

  • Install and enable the RESTful Web Services module. This may be already included with core Drupal installation.
  •  

  • Install the Serialization module required for REST API support:

 

drush en serialization -y

 

  • Enable the RESTful Web Services module:

 

drush en rest -y

 

Configure Azure Cognitive Services on Drupal

 

  • Create a custom module if there isn't already a module in place for Azure services. Create a directory for your module:

 

mkdir web/modules/custom/azure_cognitive

 

  • Create your .info.yml file to define your custom module:

 

name: 'Azure Cognitive Services'
type: module
description: 'Integration with Microsoft Azure Cognitive Services.'
core_version_requirement: ^8 || ^9
package: Custom
dependencies:
  - drupal:rest
  - drupal:serialization

 

  • Use hook_rest_resource\_config() to configure the REST resource for Azure Cognitive Services:

 

/**
 * Implements hook_rest_resource_config().
 */
function azure_cognitive_rest_resource_config() {
  $resources = [];
  $resources['cognitive_services'] = [
    'uri_paths' => [
      'canonical' => '/api/cognitive-services',
    ],
    'methods' => ['GET', 'POST'],
    'authentication_types' => ['basic_auth'],
  ];
  return $resources;
}

 

Set Up Authentication Keys

 

  • In the azure\_cognitive.module file, set up a function to authenticate using your Azure details.

 

/**
 * Helper function to authenticate to Azure.
 */
function azure_cognitive_authenticate() {
  $apiKey = 'YOUR_AZURE_API_KEY';
  $endpoint = 'YOUR_AZURE_ENDPOINT';
  $client = new \GuzzleHttp\Client();

  $response = $client->post($endpoint, [
    'headers' => [
      'Ocp-Apim-Subscription-Key' => $apiKey,
    ],
  ]);

  if ($response->getStatusCode() == 200) {
    return json_decode($response->getBody()->getContents(), TRUE);
  }
  else {
    drupal_set_message(t('Unable to authenticate with Azure.'), 'error');
  }
}

 

Test the Integration

 

  • Create a simple Drupal page or form that makes use of Azure Cognitive Services via the authenticated resource API:

 

function azure_cognitive_page() {
  $result = azure_cognitive_authenticate();
  // Example of using the result in your application logic.
  if ($result) {
    return [
      '#markup' => t('Connected to Azure Cognitive Services!'),
    ];
  }
  return [
    '#markup' => t('Connection failed!'),
  ];
}

 

Conclusion

 

  • Ensure your API endpoints and authentication keys are kept secure and not exposed in your version-controlled files.
  •  

  • Regularly check for updates on the SDK and Debian modules to maintain compatibility with Azure and Drupal updates.

Troubleshooting Microsoft Azure Cognitive Services and Drupal Integration

How do I connect Azure Cognitive Services API to my Drupal site?

 

Set Up Azure Cognitive Services

 

  • Register on Azure and create a Cognitive Services account to get your API key and endpoint URL.
  •  

  • Make sure to note down the key and URL; you'll need them for your Drupal integration.

 

Install Drupal Module

 

 

drush en azure_cognitive_services -y

 

Configure API Keys

 

  • Navigate to CONFIGURATION > Azure Cognitive Services in your Drupal admin dashboard.
  •  

  • Enter the API key and endpoint URL you obtained from Azure.

 

Create a Service Connection

 

  • Use Drupal's interface to map Azure services like Text Analytics, Speech, or Vision according to your needs.
  •  

  • Test the connection to ensure it's properly set up and troubleshoot any issues.

 

Use API in Custom Code

 

  • Implement custom modules or themes in Drupal to make API calls as needed, utilizing the configured Azure connection.

 

$response = \Drupal::service('azure_cognitive_services')->analyzeText('sample text');

 

Why is my Azure Cognitive Services integration not working in Drupal?

 

Check API Key and Endpoint

 

  • Ensure the API key has the right permissions and is correctly configured in Drupal. Double-check the endpoint URL for any typos.

 

Verify Module Configuration

 

  • Go to Admin → Configuration → Azure Cognitive Services. Ensure settings align with your Azure account.

 

Debugging Connectivity Issues

 

  • Ensure your server can reach Azure's endpoints. Use command-line tools like curl:

 

curl -I https://<your-endpoint>.cognitiveservices.azure.com

 

Inspect Error Logs

 

  • Review Drupal's logs at Admin → Reports → Recent log messages for error details.
  •  

  • Check server error logs for further insights.

 

Review Network Settings

 

  • Check if firewall or network settings block external API calls.

 

Test with Different API Features

 

  • Verify if specific features or endpoints of Azure Cognitive Services are causing issues.

 

How can I handle API response errors from Azure Cognitive Services in Drupal?

 

Handling API Response Errors

 

  • When using Azure Cognitive Services in Drupal, it's crucial to properly handle API errors to ensure a robust application.

 

Enable Error Logging

 

  • Ensure Drupal logging is enabled to track any API errors effectively. You can use the 'syslog' or 'watchdog' for error logging.
\Drupal::logger('azure_cognitive')->error($message);

 

Check HTTP Status Codes

 

  • Use the Guzzle HTTP client in Drupal to handle responses. Check for non-200 HTTP status codes to capture errors efficiently.
$response = $client->request('GET', $url);
if ($response->getStatusCode() !== 200) {
  // Handle the error
}

 

Handle Specific Error Codes

 

  • Specific error codes can be managed using a switch or if-else conditions to tailor error handling strategies.
$error_code = $response->getStatusCode();
switch ($error_code) {
  case 401:
    // Unauthorized request
    break;
  case 429:
    // Too many requests
    break;
}

 

Implement Retry Logic

 

  • For transient errors, implement retry logic with exponential backoff to improve reliability.
$options = [
  'exceptions'   => false,
  'retry'        => 3,
  'backoff'      => function ($retry) {
    return pow(2, $retry) * 1000;
  }
];
$response = $client->request('GET', $url, $options);

 

Display User-Friendly Messages

 

  • Translate technical errors into user-friendly messages to ensure a good user experience.
$message = t('An error occurred while processing your request. Please try again later.');
drupal_set_message($message, 'error');

 

Test Your Error Handling

 

  • Regularly test your error implementations using mocked responses to ensure resilience and correct functionality.
