Implementing Oauth2 login, Fatal error: Class 'Google_Service' not found

Question

I am updating my website's login system from LightOpenID to Google's Oauth 2.0.

When I require the Client.php and the Service/Oauth2.php I get an error

Fatal error: Class 'Google_Service' not found in /home/myname/repos/website_current/lib/google-api-php-client/src/Google/Service/Oauth2.php on line 32

The code I am using (from my login.php file) looks like this

require_once(dirname($_SERVER['DOCUMENT_ROOT']).'/lib/autoload.php');
require('Google/Client.php');
require('Google/Service/Oauth2.php');
echo "exit";
exit();

I have added the include path in the PHP.ini (in /etc/php5/apache2/php.ini) as

include_path = ".:/usr/local/lib/php:/home/myname/repos/website_current/lib/google-api-php-client/src"

So its seems my Oauth2.php file can't see any of the other includes including the class 'Google_Service' which is one folder up in 'Service.php'.

My folder structure looks like this:

lib/
... autoload.php
... functions.php
... google-api-php-client/
    ... src/
        ... Google/ (etc etc)
public_html/
... login/
    ...login.php

I have no idea why this is occuring. The include path should be seen, and shows up as an included path using phpinfo(); Can someone please give me some insight?

Make sure you add the line BEFORE any other Google "require_once" lines.

require_once 'google-api-php-client/autoload.php';

I had it last and it had me scratching my head for a good 10 minutes.

autoload.php has been moved -- now use: require_once 'Google/autoload.php'; – Brett Pennings Jun 14 '15 at 18:53

Per the instruction on github:

require_once 'google-api-php-client/autoload.php'; // or wherever autoload.php is located

In your case it seems like the above include url should work fine.

I also have required autoload.php. Forgot to add it into the code above (See above edits). Is autoload meant to be in a specfiic place? Maybe the Oauth2.php file cant load classes properly? – Gambles Feb 05 '15 at 19:32

The new way of doing this (circa early 2016) is

require_once("Google/autoload.php");

(Assuming you have already set your include path to have /path/to/google-api-php-client/src)

Not sure if you will see this but I get this error when I add the autoload This library must be installed via composer or by downloading the full package. Do I not already have the full package? – JianYA Mar 05 '18 at 15:09

As per the official instructions, you are right but this is not working for me. They make it so complex! – Gary Carlyle Cook Apr 21 '17 at 18:47

To this version https://github.com/google/google-api-php-client this is a posible solution

set_include_path("google-api-php-client/src/" . PATH_SEPARATOR . get_include_path());

//.....

require_once 'Google/Service.php';
//.....

While working with Google API integration

Fatal error: Class 'abc' not found

error comes when there is definitely something different between the library you have in composer.json above, and the library that is actually being auto-loaded.

had same problem just changed in my composer.json

{"require": {"google/apiclient": "1.0.*@beta"}}

to

{"require": {"google/apiclient": "2.0.*"}}

and then execute php composer.phar update (make sure you give right path for .phar file)

Now it is deprecated and moved to Sub Google directory. Following is the new default path: google-api-php-client-master\src\Google\autoload.php

After following what Durandal had posted I tried it, but the new path for me is :

require_once 'google-api-php-client/src/Google/autoload.php';

Once I made this changed it worked. Thanks for the help.
