php - google drive API authorize issue -

I have followed the tutorial on Google Drive, to say that authentication / access token we use to refresh token We continue to do so, so we do not need to be certified / every time we ask to authorize an API call that

code:.

  require_once 'google-api-php-client / src / Google_Client.php'; Need_once 'google-api-php-client / src / contrib / Google_DriveService.php'; $ Client = new Google_Client (); // console $ client- & gt; Get your credentials from setClientId ('Client ID'); $ Client- & gt; Set client SERT ('customer secret'); $ Customer & gt; SetRedirectUri ('url'); $ Customer & gt; SetScopes (array ('https://www.googleapis.com/auth/drive')); $ Customer & gt; SetAccessType ('offline'); $ Service = new Google_DriveService ($ customer); $ AuthUrl = $ client- & gt; CreateAuthUrl (); // Access token $ access to Exchange authorization code token = $ client- & gt; Authenticate (); $ Customer & gt; SetAccessToken ($ accessToken); $ Files = $ service-> File-> List files (); Echo "& lt; east & gt;"; Print_r ($ files);  

This gives me a list of files and folders, but every time I refresh the page that takes me back to the Google authorization page I can save the access token in the database How do I use it, and how to make API calls without user authorization?

Any ideas ??

Thank you,

Probably, using this P12 key Server is better to use the server for authentication:

<. P> You can impersonate a user account and all files will be accessed from your server

  $ client_email = '1234567890-a1b2c3d4e5f6g7h8i@developer.gserviceaccount.com'; $ Private_key = file_get_contents ('MyProject.p12'); $ User_to_impersonate = 'user@example.org'; $ Private_key = file_get_contents ($ pkey); // notasecret $ scopes = array ('https://www.googleapis.com/auth/drive'); $ Credits = new \ Google_Auth_AssertionCredentials ($ client_email, $ scope, $ private_key, 'notasecret', // default P12 password 'http://oauth.net/grant_type/jwt/1.0/bearer', // default grant type $ user_to_impersonate ); $ Client = new \ Google_Client (); $ Customer & gt; SetAssertionCredentials ($ credits); If (; getAuth () - & gt; $ Customer & gt ;AccessTokenExpired ()) {$ Customer & gt; GetAuth () - & gt; RefreshTokenWithAssertion (); } $ Service = new \ Google_Service_Drive ($ customer); $ Files = $ service-> File-> List files (); Echo "counting files =". Count ($ files). "& Lt; br & gt;"; Forex Currency ($ item $ item) {echo "title =". $ Item ['title'] "& Lt; br & gt;"; }  

This will give you all the files listed in your Google Drive without any customer user interaction.
