GoogleClient

Google services API library. Supported APIs:

• OAuth2 authorization API
• Google Cloud Messaging API
• Android Publisher API: in-app products, purchases products and purchases subscriptions

Installation

For install library you need to modify your composer configuration file

    "alxmsl/googleclient": "*"

And just run installation command

    $ composer.phar install

OAuth2 authorization

To authorize client via Google OAuth2 you need to create WebServerApplication instance with needed scopes using client identifier, client secret and redirect uri from you console

    $Client = new WebServerApplication();
    $Client->setClientId(<client id>)
        ->setClientSecret(<client secret>)
        ->setRedirectUri(<redirect uri>);

...make authentication url

    $Client->createAuthUrl([
            'https://www.googleapis.com/auth/androidpublisher',
        ]
        , ''
        , WebServerApplication::RESPONSE_TYPE_CODE
        , WebServerApplication::ACCESS_TYPE_OFFLINE
        , WebServerApplication::APPROVAL_PROMPT_FORCE);

...compete authorization in browser and give authorization code. With this code you could get access token

    $Token = $Client->authorizeByCode(<code>);
    print((string) $Token);

You could see examples webclient.uri.php about uri creation, and webclient.authorize.php about code authentication. Already you could use completed script authorize.php

$ php bin/authorize.php
Using: /usr/local/bin/php bin/authorize.php [-h|--help] [-o|--code] -c|--client -r|--redirect -s|--scopes -e|--secret
-h, --help  - show help
-o, --code  - authorization code
-c, --client  - client id
-r, --redirect  - redirect uri
-s, --scopes  - grant scopes
-e, --secret  - client secret

$ php bin/authorize.php --client='my-client@id' --secret='clientsecret' --redirect='http://example.com/oauth2callback' 
    --scopes='https://www.googleapis.com/auth/androidpublisher'
https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=my-client@id
&redirect_uri=http%3A%2F%2Fexample.com%2Foauth2callback&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fandroidpublisher
&access_type=offline&approval_prompt=force

$ php bin/authorize.php --client='my-client@id' --secret='clientsecret' --code='authorization/code'
    access token:  ya.AccES5_T0keN
    expires in:    3558
    id token:      id.T0kEn
    refresh token: refrE5H_T0KEN
    token type:    Bearer

Of course, I created scripts for token refreshing

$ php bin/refresh.php
Using: /usr/local/bin/php bin/refresh.php [-h|--help] -c|--client -e|--secret -t|--token
-h, --help  - show help
-c, --client  - client id
-e, --secret  - client secret
-t, --token  - refresh token

...and token revoking

$ php bin/revoke.php --help
Using: /usr/local/bin/php bin/revoke.php [-h|--help] -t|--token
-h, --help  - show help
-t, --token  - revoked token

Google Cloud Messaging

For create Google Cloud Message you need to create child for class PayloadData and define getDataFields method. You could see example below or in gcm.php

    // Create payload data class
    final class NewPayloadData extends PayloadData {
        protected function getDataFields() {
            return [
                'test' => 'test_01',
            ];
        }
    }
    
    // Create and initialize payload message instance
    $Message = new PayloadMessage();
    $Message->setRegistrationIds('DeV1CeT0kEN')
        ->setType(PayloadMessage::TYPE_JSON)
        ->setData(new NewPayloadData());
    
    // Create GCM client
    $Client = new Client();
    $Client->getRequest()->setConnectTimeout(60)
        ->setSslVersion(6);
    $Client->setAuthorizationKey('aUTH0R1Z4t1oNKEy');
    
    // ...and send the message
    $Response = $Client->send($Message);
    var_dump($Response);

You could use completed script

$ php bin/gcm.php
Using: /usr/local/bin/php bin/gcm.php [-h|--help] [-d|--data] -i|--id -k|--key
-h, --help  - show help
-d, --data  - payload data
-i, --id  - device registration id
-k, --key  - authorization key

$ php bin/gcm.php --id='DeV1CeT0kEN' --key='aUTH0R1Z4t1oNKEy' --data='{"test":"test_01"}'
    success: 1
    failure: 0

In-app purchases

You could use In-App products API to manage products of your application. For example, you could get all product prices for all end-user countries

    $Client = new Client();
    $Client->setPackage(<package name>)
        ->setAccessToken(<access token>);
    /** @var InAppProductsResource $Resource */
    $Resource = $Client->get(<product id>);
    var_dump($Resource->getPrices());

Already, you could use inappproducts.get.php to get info about products

$ php bin/inappproducts.get.php --help
Using: /usr/local/bin/php bin/inappproducts.get.php [-h|--help] -a|--access [-p|--package] -r|--product
-h, --help  - show help
-a, --access  - access token
-p, --package  - package name
-r, --product  - product id

Purchases products

Using Purchases.Products API you could check user purchases in third-party server application. For example if purchase purchased and does not cancel now:

    use alxmsl\Google\AndroidPublisher\Purchases\Client;
    use alxmsl\Google\AndroidPublisher\Purchases\Products\Resource as ProductsResource;

    $Client = new Client();
    $Client->setPackage(<package name>)
        ->setAccessToken(<access token>);
    
    /** @var ProductsResource $Resource */
    $Resource = $Client->get(<product id>, <purchase token>);
    var_dump($Resource->isPurchased() && !$Resource->isCancelled());

Purchases subscriptions

This library allows all operations over user subscriptions using some scripts: get, cancel, defer, refund and revoke

How to check subscription, for example:

    use alxmsl\Google\AndroidPublisher\Purchases\Subscription\Resource as SubscriptionsResource;
    use alxmsl\Google\AndroidPublisher\Purchases\Subscription\SubscriptionsClient;
    
    $Client = new SubscriptionsClient();
    $Client->setPackage(<package name>)
        ->setAccessToken(<access token>);
    
    /** @var SubscriptionsResource $Resource */
    $Resource = $Client->get(<subscription id>, <purchase token>);
    var_dump($Resource->isAutoRenewing() && !$Resource->isExpired());

Tests

For completely tests running just call phpunit command

    $ phpunit
    PHPUnit 4.7.3 by Sebastian Bergmann and contributors.
