How do I configure OAuth credentials for Google Cloud Storage in Laravel

1. Create a Google Cloud Platform Project:
- Go to the Google Cloud Console (https://console.cloud.google.com/) and create a new project.

2. Enable the Google Cloud Storage API:
- In the Google Cloud Console, navigate to the "APIs & Services" section and enable the "Google Cloud Storage API" for your project.

3. Create OAuth Credentials:
- In the "APIs & Services" section, go to the "Credentials" tab and click on "Create Credentials".
- Select "OAuth client ID" as the credential type.
- Choose the application type as "Web application".
- Add the authorized redirect URIs, which will be in the format `https://your-app.test/login/google/callback` (replace `your-app.test` with your actual domain).
- Click "Create" to generate the OAuth client ID and client secret.

4. Configure the Credentials in Laravel:
- In your Laravel application's `.env` file, add the following environment variables:

     GOOGLE_CLIENT_ID=your-google-client-id
     GOOGLE_CLIENT_SECRET=your-google-client-secret
     GOOGLE_REDIRECT=https://your-app.test/login/google/callback
     

- In your `config/services.php` file, add the following configuration:

php
     'google' => [
         'client_id' => env('GOOGLE_CLIENT_ID'),
         'client_secret' => env('GOOGLE_CLIENT_SECRET'),
         'redirect' => env('GOOGLE_REDIRECT'),
     ],
     

5. Install the Google Cloud Storage Package:
- Install the `spatie/laravel-google-cloud-storage` package using Composer:

     composer require spatie/laravel-google-cloud-storage
     

6. Configure the Google Cloud Storage Disk:
- In your `config/filesystems.php` file, add the following configuration for the Google Cloud Storage disk:

php
     'gcs' => [
         'driver' => 'gcs',
         'key_file_path' => env('GOOGLE_CLOUD_KEY_FILE', base_path('service-account.json')),
         'project_id' => env('GOOGLE_CLOUD_PROJECT_ID', 'your-project-id'),
         'bucket' => env('GOOGLE_CLOUD_STORAGE_BUCKET', 'your-bucket'),
         'path_prefix' => env('GOOGLE_CLOUD_STORAGE_PATH_PREFIX', ''),
         'storage_api_uri' => env('GOOGLE_CLOUD_STORAGE_API_URI', null),
         'api_endpoint' => env('GOOGLE_CLOUD_STORAGE_API_ENDPOINT', null),
         'visibility' => 'public',
         'visibility_handler' => null,
         'metadata' => ['cacheControl' => 'public,max-age=86400'],
     ],
     

7. Add the Required Environment Variables:
- In your `.env` file, add the following environment variables:

     GOOGLE_CLOUD_KEY_FILE=service-account.json
     GOOGLE_CLOUD_PROJECT_ID=your-project-id
     GOOGLE_CLOUD_STORAGE_BUCKET=your-bucket
     

- Replace the placeholders with your actual Google Cloud project ID and storage bucket name.

After following these steps, your Laravel application should be configured to use Google Cloud Storage with the necessary OAuth credentials.
