Now I know this is a common topic that has been over the Internet especially StackOverflow. But what I do not have (or haven’t yet seen) is a straight solution for the token being maintained over a session.<\/p>\n
I’m using the Google APIs Client Library for PHP .<\/p>\n
My Query:<\/strong> I have one index.php where I fetch the user data (such as name) using the Google_Oauth2Service from the PHP client lib. The user is authenticated successfully and all goes well. Now I’d like to use the URL Shortening service and therefore I have a shorten.php where I have the code to try fetch the short URL. Some how this doesn’t work.<\/p>\n index.php<\/strong><\/p>\n Here I have started the session and made an object of the Google_Client. I have declared the client id, secret and all other details.<\/p>\n Then I get the access token on successful authentication and store it in the Session variable so that when I try to fetch the short url (using jQuery ajax) from shorten.php, I can use the existing token.<\/p>\n Now in shorten.php<\/strong><\/p>\n This is the exact line where the code breaks From the apache error logs<\/strong> :<\/p>\n When I dump the Google_Client variables on the index.php and shorten.php files, this is what I get.<\/p>\n index.php<\/strong><\/p>\n shorten.php<\/strong><\/p>\n and both aint the same so I’m assuming that there is something not right here. Help or direction please.<\/p>\n","protected":false},"excerpt":{"rendered":" Now I know this is a common topic that has been over the Internet especially StackOverflow.
