title: google-api-php-client: Invalid client secret JSON file
body: <p>Seems that the latest version of the google-api-php-client for PHP doesn't line up with the docs @ <a href="https://developers.google.com/drive/web/examples/php" rel="noreferrer">https://developers.google.com/drive/web/examples/php</a></p>
  
  <p>Looking at the src code I'm seeing that it's looking for keys in the downloaded JSON that the setAuthConfigFile() method can't find: client_secret, installed, web, redirect_uris (others?) are not present in the downloaded JSON.  Only private_key_id, private_key, client_email, client_id, and type are present.</p>
  
  <p>The code and docs seem really disorganized and out of sync... wouldn't be the first for Google.  Has anyone gotten OAuth working recently using that library?</p>
