FuelPHP Forums

I use the Opauth that's integrated in the Auth package, and have no issues. So I can't help you in this case, it seams to be something specific to that package you use.

There are complete examples in the docs (http://fuelphp.com/docs/packages/auth/examples/opauth.html).

All you need to do is to add the required strategies to the composer.json file in the Fuel root, and create the config file in app/config, containing the required keys for those strategies. And the rest happens magically, providing you have Auth installed (either SimpleAuth or OrmAuth), as it works integrated with those.

Hi Harro,

I already try it, but it doesn't work at all. Where is my mistake ?

the auth.php config file :
return array(
    'driver'                 => 'Ormauth',
    'verify_multiple_logins' => true,
    'salt'                   => 'put_your_salt_here',
    'iterations'             => 10000,
);

the opauth.php config file :
'path' => '/CMS-Sites/funding_funnel/public/index.php/login/oauth',

'callback_url' => '/CMS-Sites/funding_funnel/public/index.php/login/callback',

'callback_transport' => 'session',

'Strategy' => array(

        'Facebook' => array(
                    'app_id'     => '........my app id.........',
                    'app_secret' => '....my app secret....',
                    'scope'      => array('user_birthday', 'email', ),
             ),

        'Google' => array(
                'client_id'     => '....my client_id.....',
                'client_secret' => '...my client secret....',
            ),
...

My login controller :

class Controller_Login extends Controller
{

    public function action_oauth($provider = null)
    {
        // bail out if we don't have an OAuth provider to call
        if ($provider === null)
        {
            //\Messages::error(__('login-no-provider-specified'));
            \Response::redirect_back();
        }

        // load Opauth, it will load the provider strategy and redirect to the provider
        \Auth_Opauth::forge();
    }


}

I don't even put a callback method yet because I receive an error when I call like this :

http://kbx3.de/CMS-Sites/funding_funnel/public/index.php/login/oauth/facebook

The error is :
Auth\OpauthException [ Error ]: Opauth strategy "" is not supported

PKGPATH/auth/classes/auth/opauth.php
@ line 134

// check if we have a strategy defined for this provider
132            if ( ! \Config::get('opauth.Strategy.'.$config['provider'], false))
133            {
134                throw new \OpauthException('Opauth strategy "'.$config['provider'].'" is not supported');
135            }

What am I doing wrong ??

If I don't set a 'path' in the opath.php config file, I receive an error like this :

Hi Harro,

I've made a fresh install with the last FuelPHP version.

I've setted in the auth.php config file, the driver as being 'Ormauth'. I've runned the migrations and all the tables have been created. Then I've read the docu regarding the Ormauth usage in order to not skip anything.

I've copied the opauth.php config file from the packages/auth/config/opauth to the app/config/opauth.php and there i've settled my salt and put all the strategies credentials. Nothing else.

Then I have created a controller named login, which has the method from the example : action_oauth($provider)

When I go to the browser http://kbx3.de/CMS-Sites/funding_funnel/login/oauth/facebook I receive this error :

Auth\OpauthException [ Error ]: No providers table configured. At the moment, only SimpleAuth and OrmAuth can be auto-detected.

Even if in the documentations says that the providers table (which was already created as I said), doesn't have to be set in the config (and as you told me, that you don't do it in your opaut.php config file), I wonder why I receive this error.

If I set the table name in the opauth.php config file like this : 'table' => 'users_providers', it goes further but I receive immediately another error :

Fuel\Core\PhpErrorException [ User Error ]: Unsupported or undefined Opauth strategy - login

DOCROOT/fuel/vendor/opauth/opauth/lib/Opauth/Opauth.php @ line 120

117

119            } else {
120                trigger_error('Unsupported or undefined Opauth strategy - '.$this->env['params']['strategy'], E_USER_ERROR);
121            }
122        } else {
123            $sampleStrategy = array_pop($this->env['Strategy']);

What is wrong now ?

You can also try to replace line 129 with

$provider = explode('/', substr(implode('/', \Request::main()->uri->get_segments()), strlen($config['path']) - 1));

and see if that fixes it?

How is tat possible, when I call in the oauth method inside the Login controller like this : \Auth_Opauth::forge();  So it's clear that it has to use the opauth class from the auth namespace ?

It includes then the one from the vendor and there is a problem with detecting the correct path ?

I found that not the provider is the problem, but the strategy.

On vendor/opauth/opauth/lib/Opauth/Opauth.php, inside function run(), the first line is $this->parseUri();
and inside the parseUri() method, it says

if ( ! empty($this->env['params'][0]))
{
      $this->env['params']['strategy'] = $this->env['params'][0];
}

but in my case, the $this->env['params'] looks like this :

[params] => Array
        (
            [0] => login
            [1] => oauth
            [2] => facebook
        )

so i've changed to do like this

if ( ! empty($this->env['params']['strategy']))
{
      $this->env['params']['strategy'] = $this->env['params']['strategy'];
}

now it redirects me to the provider. Let's see what comes next :)

It's because of what I wrote earlier.

Because you have two additional URI segments, everything is shifted by two segments. And that is why $this->env['params'] in Opauth contains 3 entries instead of only one, the strategy.

This needs to be fixed in the Opauth Auth driver because it's a Fuel issue. I need to setup a similar environment so I can test and fix it. I'll try to find the time in the next few days.

I don't know, I've never used Warden.

I use the registration and password recovery methods are shown in the example code, it would not be difficult to add email verification to that, in our application we also do that.

Just to let you know I've got a setup working, and I can recreate your error. I'll try to push a fix for it this weekend.

Fix was pushed yesterday.

As it also contains fixes in the framework (https://github.com/fuel/core/commit/a1ac30d02ff716375ee9093d397c595945a7b152), you should upgrade to 1.7/develop to be able to use this fix now, or wait for the next official release (which isn't planned yet).

You should NOT define any paths anywhere, it should work automatically!

If it works for the other strategies, but not for Google, then Opauth has a driver bug, which they have to fix.

Please verify if you have the latest version of the driver, and if so, report the issue here: https://github.com/opauth/google/issues
