Invalid json in service response - php

Question

I'm trying to get my profile info using the PHP API, yet it doesn't seem to be working in the last couple days.
My code is as follows:
<?php
try {
$client_id = '****************.apps.googleusercontent.com';
$client_secret = '*********************';
$redirect_uri = '**********************';
$google_key = '***************';
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->setDeveloperKey($google_key);
$client->setAccessType('offline');
$client->setScopes(array('https://www.googleapis.com/auth/userinfo.email','https://www.googleapis.com/auth/userinfo.profile'));
$plus = new Google_Service_Plus($client);
if(isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$accessToken = $client->getAccessToken();
$refreshToken = json_decode($accessToken)->refresh_token;
setcookie('refresh_token', $refreshToken, (time()+60*60*24*30));
setcookie('access_token', $accessToken, (time()+60*60*24*30));
header('Location: ./');
exit();
}
if(isset($_COOKIE['access_token']) && $_COOKIE['access_token']) {
$refreshToken = json_decode($_COOKIE['access_token'])->refresh_token;
$accessToken = $_COOKIE['access_token'];
setcookie('access_token', $accessToken, (time()+60*60*24*30));
$client->setAccessToken($_COOKIE['access_token']);
} else {
$authUrl = $client->createAuthUrl();
}
if($client->getAccessToken()) {
$accessToken = $client->getAccessToken();
setcookie('access_token', $accessToken, (time()+60*60*24*30));
if(isset($plus)){
$userInfo = $plus->people->get('me');
}
}
if($client->isAccessTokenExpired() && isset($userInfo)){
$refreshToken = $_COOKIE['refresh_token'];
$client->refreshToken($refreshToken);
$newtoken = $client->getAccessToken();
setcookie('access_token', $newtoken, (time()+60*60*24*30));
header('Location: ./');
exit();
}
} catch (Google_Service_Exception $gse){
error_log($gse, 0);
} catch (Google_Auth_Exception $gae){
error_log($gae, 0);
}
?>
I will be using a database soon, but i'd like to get it working with cookies first. The error I'm getting is as follows:
[05-Aug-2015 20:40:36 Europe/London] exception 'Google_Service_Exception' with message 'Error calling GET https://www.googleapis.com/plus/v1/people/me?key=**********************: (403) ‹' in /home5/commodit/public_html/workflow/src/Google/Http/REST.php:110

#9 {main}
I also get a "Response not valid json" if i try to use OAuth2 instead of Google Plus as the service.

Thanks for any help!

P.S - I have also tried the "opt_params" variable but it still says invalid JSON :(

Answer 1

I suggest to check the Google/Config.php file, there are several default parameters that can be adjust to get solution for different problems.
In my case i was also receiving an invalid-json-in-service-response, i was sure of correct credential settings, i tryed to run the URL that was passed to Google API with GET protocol and query string, and always had full plain text in json format answer, so i looked at "disable_gzip" parameter and modifiy it to see what was the behaviour if changed.
'Google_Http_Request' => array(
// Disable the use of gzip on calls if set to true. Defaults to false.
'disable_gzip' => self::GZIP_DISABLED, //self::GZIP_ENABLED,
// We default gzip to disabled on uploads even if gzip is otherwise
// enabled, due to some issues seen with small packet sizes for uploads.
// Please test with this option before enabling gzip for uploads in
// a production environment.
'enable_gzip_for_uploads' => self::GZIP_UPLOADS_DISABLED,
),
You may set different values for a Google_Client Config, Class Attribute invoking the defined method.
public function setClassConfig($class, $config, $value = null)
