Problem in refreshing access token

GoogleCodeExporter commented 8 years ago

Hi,

I am facing problem in refreshing the access token. Can you please tell me what 
code I need to implement for refreshing the token? OR the api itself refreshes 
it. Please clarify.

Thanks,
Chitrangada

The client library does indeed refresh the access token for you. What type of 
issue are you seeing?

Thank you Chirag.

I want to refresh the token in certain condition. Now I have used the code at 
corresponding place. But can you please tell me when the library refreshes it?

The client library will refresh the access token (if needed) *before* making an 
authenticated API request.
This happens if the access token is older than 3600 seconds.

I think library isn't refreshes the token for me. If it does so then why I am 
getting this error?

ERROR: Fatal error: Uncaught exception 'apiAuthException' with message 'Error 
fetching OAuth2 access token, message: 'invalid_grant''.......

You'll get the invalid_grant error when you try to use the same authorization 
code. (You get this code when you're redirected from google back to your 
application)

The sample applications show how you can use the authorization code only once.
if (isset($_GET['code'])) {
  $client->authenticate();
  $_SESSION['access_token'] = $client->getAccessToken();
  header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']); // Strip the authorization code
}

The full example is available here:

Hey Chirag,

you exactly included the piece of code which I think will not work, when served 
from https !
Sent it to Chris before, rewrote it to:

if (isset($_GET['code'])) {
  $client->authenticate();
  $_SESSION['access_token'] = $client->getAccessToken();

 if(isset($_SERVER['HTTPS'])){ $_PROT = 'Location: https://'; } else { $_PROT = 'Location: http://'; } 
  header($_PROT . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']);
}

i'm having the same issue. i'm using the HelloAnalyticsApi.php tutorial 
(https://developers.google.com/analytics/resources/tutorials/hello-analytics-api
), and have everything working great. The script successfully requests the 
permission from Google, returns a code, exchanges it for an access token, and 
then i'm able to query the service and receive data for my application.

However, when the browser is closed or session cleared, I have to 
re-authenticate everytime. I added the following to the HelloAnalyticsApi.php:
$client->setAccessType('offline');

When checking the access token, it does indeed include a refresh token. I've 
got all the pieces here but just need to put it together. I found the following 
explanation of how to use the refresh token 
(https://developers.google.com/accounts/docs/OAuth2WebServer#refresh) but this 
doesn't include instructions on how to use it with the google-api-php-client.

this turned out to be more simple than i had anticipated. starting with the 
hello analytics api, i added the following code and it appears to be able to 
connect now without re-authenticating.

// begin custom code
$client->setAccessType('offline');

if (isset($_SESSION['token'])) {
    // echo $_SESSION['token'];
    echo '<br />';
    echo '<br />';
    $authObj = json_decode($_SESSION['token']);
    $accessToken = $authObj->access_token;
    $refreshToken = $authObj->refresh_token;
    $tokenType = $authObj->token_type;
    $expiresIn = $authObj->expires_in;
    echo 'access_token = ' . $accessToken;
    echo '<br />';
    echo 'refresh_token = ' . $refreshToken;
    echo '<br />';
    echo 'token_type = ' . $tokenType;
    echo '<br />';
    echo 'expires_in = ' . $expiresIn;
    echo '<br />';
    echo '<br />';
}

$refreshToken = '1/ewPvNg6_2toqDtCaw2bdIUhgQpGF7koqLAIurSpo4Uk';
$client->refreshToken($refreshToken);
// end custom code

In my case : $authObj = json_decode($_SESSION['token']);
return all indicated vars but no "refresh_token" in json decoded session.

See src/auth/apiOAuht2.php function authenticate line :: 84 refresh token not 
setted 

Could you help me to have the refresh token which permit me to execute  
$client->refreshToken($refreshToken);

I've been trying to use the google analytics php api with the hello api 
tutorial and there seems to be a few inconsistencies with the latest library 
(classes changed name and locations).

I've gotten my code to run up to the $client->authenticate(); call but I never 
receive a response from the authenticate function. Is the library functional? 
(version google-api-php-client-0.6.0.tar.gz)

you need to set your application to $client->access_type(offline); check this 
link out for more info :

Hi Chirag,
Is there some way I can just destroy the token, once the user logs in. So that 
I am faced with absolutely no problems.

Thanks,
Rajat
