Requirements

You need Server account credentials as JSON which you can generate within your Google Console. You will receive a file which looks like the following example:

{
  "type": "service_account",
  "project_id": "foo.bar:api-project-XXXXXXXXXXXXXX",
  "private_key_id": "XXXXXXXXXXXXXX",
  "private_key": "-----BEGIN PRIVATE KEY-----\nXXXXXXXXXXXXXX\n-----END PRIVATE KEY-----\n",
  "client_email": "cloud-storage-web-server@api-project-XXXXXXXXXXXXXX.foo.bar.iam.gserviceaccount.com",
  "client_id": "XXXXXXXXXXXXXX",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/cloud-storage-web-server%40api-project-XXXXXXXXXXXXXX.foo.bar.iam.gserviceaccount.com"
}

Setup credentials

Gstorage needs your credentials in order to be constructed. For this we need to use the ServerAccountCredentials which offers two methods to load our credentials.

Load from params

Use client_email and private_key from your JSON file above for this method.

$credentials = (new ServerAccountCredentials())->loadFromParams(
    "cloud-storage-web-server@api-project-XXXXXXXXXXXXXX.foo.bar.iam.gserviceaccount.com",
    "-----BEGIN PRIVATE KEY-----\nXXXXXXXXXXXXXX\n-----END PRIVATE KEY-----\n"
);

Load from JSON file

Specify the file path for your JSON file. Lets assume we saved our file within the same folder and named it credentials.json.

$credentials = (new ServerAccountCredentials())->loadFromJsonFile('credentials.json');

Instantiate Gstorage class

Now all what needs to be done is to use $credentials:

$gstorage = new Gstorage($credentials);

Upload a file

Lets upload a file. We will construct an upload object and receive a simple object back.

// upload object
$data = new UploadData('YOUR-BUCKET-NAME');

// load file via URL
$data->loadWithFile('https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png');

// upload file
$objectData = $gstorage->upload($data); // ObjectData|null

if ($objectData)
{
    var_dump([
        'bucket'     => $objectData->getBucket(),
        'id'         => $objectData->getFileName(),
        'url_public' => $objectData->getUrlPublic(),
    ]);
}

Upload via BLOB

In case you have the file data already you can upload your data as following:

// our blob
$blob = file_get_contents('https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png');

// upload object
$data = new UploadData('YOUR-BUCKET-NAME');

// load file via BLOB
$data->loadWithBlob('google-logo.png', $blob);

// upload file
$objectData = $gstorage->upload($data); // ObjectData|null

if ($objectData)
{
    var_dump([
        'bucket'     => $objectData->getBucket(),
        'id'         => $objectData->getFileName(),
        'url_public' => $objectData->getUrlPublic(),
    ]);
}

Delete file

Lets delete the upload from our Google Logo Blob:

$response = $gstorage->delete(
    new ObjectData('YOUR-BUCKET-NAME', 'google-logo.png')
);

var_dump($response); // true|false

Complete example

$gstorage = new Gstorage(
    (new ServerAccountCredentials())->loadFromJsonFile('credentials.json')
);

// upload object
$data = new UploadData('YOUR-BUCKET-NAME');

// load file via URL
$data->loadWithFile('https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png');

// upload file
$objectData = $gstorage->upload($data); // ObjectData|null

if ($objectData)
{
    var_dump([
        'bucket'     => $objectData->getBucket(),
        'id'         => $objectData->getFileName(),
        'url_public' => $objectData->getUrlPublic(),
    ]);
}
