}
} else {

$response = $this->googleplus->plus->people->get('me');
_print($response->id);

_print($servic_exception);
}
if ($response->meta->status == 201) {
return $response->response->id;
} else {
return false;
}

I think you have get authorization error because of following reason -
Not setting email id & project name using developer console link APIs & Auth->Consent Screen.
You are calling deprecated API $this->_CI->googleplus->item_scope->setId($post_data['gp_id']);. To Call this you have to use this class new Google_Service_Plus_ItemScope();
$this->_CI->googleplus->moment_body->setTarget($this->_CI->googleplus->item_scope); .To call this method you have to use this class new Google_Service_Plus_Moment();
I have setup demo code in git for you. Google-Plus-API-Codeigniter-Starter. You can use same code to start with. I have provided detailed instruction in git repository too.
You have to Register your application using Google Console Settings as below:
Go to Google Developer Console
Create Project
To Get Google+ API Access go to: APIs & Auth->APIs -> enable Google+ API
To Get client_id & client_secret go to: APIs & Auth->Credentials->Create new Client ID
To Get api_key go to: APIs & Auth->Credentials->Create New Key->Browser key
To Get application_name go to: APIs & Auth->Consent Screen
Set Email Address
Product Name
Note: Ensure you have get all the required access from google as mentioned in point 5
Conclustion: You are using Latest google-api-php-client client. And trying to call method in an older way. Hence its not working.
