Code without authorization, we set only the ApiKey applications, it works fine

require_once __DIR__ . '/php/Gapi/vendor/autoload.php'; set_include_path( __DIR__ . '/php/Gapi/src'); $client = new Google_Client(); $client->setDeveloperKey('AIzaSyAjqunVy9S_Jm8HMncSS0WZkkqBNBsebck'); $youtube = new Google_Service_YouTube($client); try{ $listSearch = $youtube->search->listSearch('id,snippet',array( 'q' => 'Dogs', 'maxResults' => 30, )); $html = ''; foreach($listSearch['items'] as $searchItem){ switch($searchItem['id']['kind']){ case 'youtube#video': $html .= '<a target="_blank" href="http://www.youtube.com/watch?v='.$searchItem['id']['videoId'].'">'.$searchItem['snippet']['title'].'</a><br>'; break; } } echo $html; } catch(Google_Service_Exception $e){ echo $e->getMessage().' '.$e->getCode(); } catch(Google_Exception $e){ echo $e->getMessage().' '.$e->getCode(); }

Code with authorization via Service account keys, does not work

 require_once __DIR__ . '/php/Gapi/vendor/autoload.php'; set_include_path( __DIR__ . '/php/Gapi/src'); $client = new Google_Client(); $client->setAuthConfig( __DIR__ . '/pn-gapi-201d1056019b.json'); $client->setScopes(array( 'https://www.googleapis.com/auth/youtube', 'https://www.googleapis.com/auth/youtube.readonly', 'https://www.googleapis.com/auth/youtube.upload', )); $client->setApplicationName('an_gapi'); $client->setAccessType("offline"); $youtube = new Google_Service_YouTube($client); try{ $listSearch = $youtube->search->listSearch('id,snippet',array( 'q' => 'Dogs', 'maxResults' => 30, )); $html = ''; foreach($listSearch['items'] as $searchItem){ switch($searchItem['id']['kind']){ case 'youtube#video': $html .= '<a target="_blank" href="http://www.youtube.com/watch?v='.$searchItem['id']['videoId'].'">'.$searchItem['snippet']['title'].'</a><br>'; break; } } echo $html; } catch(Google_Service_Exception $e){ echo $e->getMessage().' '.$e->getCode(); } catch(Google_Exception $e){ echo $e->getMessage().' '.$e->getCode(); }

  • What kind of error occurs? - Sergiks
  • {"error": "invalid_grant", "error_description": "Bad Request"} 400 - Vasily
  • Did you watch the OAuth 2.0 guide for Server to Server Applications ? - there is different than what you have implemented. - Sergiks
  • Yes, I saw this example, but I think it’s not quite suitable for me, in this example they are authorized as a cloud administrator to have access to all user data inside the cloud, I want to manage my YouTube channel and allow users of my site to upload Video on my channel - Vasily
  • The interaction takes place between the servers, your users do not have access there - so you can give full access. But read the link on the section “ Delegating Domain ”, Section 6, which you obviously missed. - Sergiks

How to set application rights - described in the section Delegating domain-wide authority to the service account - there in p. 6 you will specify only access to youtube, youtube.upload.

  • $ user_to_impersonate = 'user@example.org'; $ credentials = new Google_Auth_AssertionCredentials ($ client_email, $ scopes, $ private_key, 'notasecret', // Default P12 password ' oauth.net/grant_type/jwt/1.0/bearer ', // Default grant type $ user_to_impersonate,); but there is no such class, but there is another Google_Auth_AssertionCredentials but when you call it, autoload does not occur, tried to uncomment it in autoload_classmap.php but the result is the same, can show how to connect it - Vasily
  • By the way the question is where to get the full client repository, the one that I had was assembled for parts github.com/google/google-api-php-client here is only part of the client without the vendor folder. Here I found the folder auth github.com/google/google-auth-library-php - Vasily
  • > without the vendor folder So there you need to run composer then. - Sergiks
