This sample application demonstrates how to Authenticate Users on App Engine Standard.

This application shows how to authenticate to Google Cloud APIs using two different methods. This sample uses Storage as an example, but these methods will work for any Google Cloud API.

1. Enable APIs - Enable the Storage API and create a new project or select an existing project.
2. Clone the repo and cd into this directory

   $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
   $ cd php-docs-samples/appengine/php72/auth
   

3. Install dependencies via Composer. Run php composer.phar install --no-dev (if composer is installed locally) or composer install --no-dev (if composer is installed globally).
4. Run gcloud app deploy to deploy to App Engine.

1. Download The Credentials - Click "Go to credentials" after enabling the APIs. Click "New Credentials" and select "Service Account Key". Create a new service account, use the JSON key type, and select "Create". Once downloaded, set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON key that was downloaded.
2. Run PHP's built-in web server with the command php -S localhost:8000 and then view the application in your browser at http://localhost:8000.
