yii2-discourse-sso
==================

[](#yii2-discourse-sso)

Discourse SSO for Yii2

Currently this extension only really deals with logging in.

Installing and configuring is quite easy.

Make sure to [follow this guide on Discourse](https://meta.discourse.org/t/official-single-sign-on-for-discourse/13045) and while setting up SSO, after getting the secret needed, configure your application like so:

```
    'discourseSso' => [
    	'class' => 'sammaye\discourse\Sso',
    	'secret' => "Some super secret, super awesome dupa secret key"
    ],

```

That is this extension installed. Now you just need to learn how to use it.

Your extension is accessible via `Yii::$app->discourseSso`. This is the location used throughout this readme.

The first step is to setup a action in your `SiteController.php` to actually do the logic of signing in someone:

```
public function actionDiscourseSso()
{
	$request = Yii::$app->getRequest();
	$sso = Yii::$app->discourseSso;

	$payload = $request->get('sso');
	$sig = $request->get('sig');

	if(!($sso->validate($payload, $sig))){
		// invaild, deny
		throw new ForbiddenHttpException('Bad SSO request');
	}

	$nonce = $sso->getNonce($payload);

	if(Yii::$app->getUser()->isGuest){
		// We add session variable to track it after we log the user in so we can redirect them back
		// This method works well with custom login methods like social networks
		Yii::$app->getSession()->set('sso', ['sso' => $payload, 'sig' => $sig]);
		return $this->redirect(['site/login']);
	}else{
		$user = Yii::$app->getuser()->getIdentity();
	}

	Yii::$app->getSession()->remove('sso');

	// We send over the data
	$userparams = [
    	"nonce" => $nonce,
    	"external_id" => (String)$user->_id,
    	"email" => $user->email,

    	// Optional - feel free to delete these two
    	"username" => $user->username,
    	"name" => $user->username,

    	//'avatar_url' => Url::to(['image/profile-image', 'id' => (String)$user->_id], 'http')
	];
	$q = $sso->buildLoginString($userparams);

	/// We redirect back
	header('Location: ' . Yii::getAlias('@discourse') . '/session/sso_login?' . $q);
}

```

and even though this goes 90% of the way it does not complete it. If you notice:

```
Yii::$app->getSession()->set('sso', ['sso' => $payload, 'sig' => $sig]);

```

We load the `sig` and `payload` into session so we can tell if we came from single sign-on so we can redirect back. This means that in our login functions (whether it be `login()` or some social login) we need to change it to (as an example for `login`):

```
public function actionLogin()
{
    if (!\Yii::$app->user->isGuest) {
        return $this->goHome();
    }

    $model = new LoginForm();
    if ($model->load(Yii::$app->request->post()) && $model->login()) {

    	if($sso = Yii::$app->getSession()->get('sso')){
    		return $this->redirect([
    			'discourse-sso',
    			'sso' => $sso['sso'],
    			'sig' => $sso['sig']
			]);
    	}

    	if($model->getUser()->profile_filled){
        	return $this->goBack();
    	}else{
    		return $this->redirect(['user/about-me']);
    	}
    } else {
        return $this->render('login', [
            'model' => $model,
        ]);
    }
}

```

Notice the `if($sso = Yii::$app->getSession()->get('sso')){`, that is where he magic happens, it detects our single sign-on and redirects back to our single sign-on function.

To customise this, just add:

```
    if($sso = Yii::$app->getSession()->get('sso')){
    	return $this->redirect([
    		'discourse-sso',
    		'sso' => $sso['sso'],
    		'sig' => $sso['sig']
		]);
    }

```

to the end of every authentication function you have.
