Class user_credentials does not exist

+1. Would it be?

foreach($this->storageMap as $name=>$class) { $storages[$name] = \Yii::$container->get($class); }

[vzani]

+1

foreach($this->storageMap as $name=>$class) { $storages[$name] = \Yii::$container->get($class); }

This solution worked for me, I believe a fix is needed

Referencing my comment on https://github.com/Filsh/yii2-oauth2-server/issues/39#issuecomment-246840160

I'm using dev-master.

JWT tokens as described in the readme aren't in the 2.0 release. They are in dev-master however.

@hiqsol @Filsh I've bootstrapped oauth2 module, but didn't seem to make a difference. Still throwing "Class user_credentials does not exist"

Also tried with bshaffer/oauth2-server-php at 1.8

    'basePath' => dirname(__DIR__),
    'bootstrap' => ['log','oauth2'],
    'controllerNamespace' => 'restapi\controllers',
    'modules' => [
        'oauth2' => [
            'class' => 'filsh\yii2\oauth2server\Module',
            'useJwtToken' => true,
            'tokenParamName' => 'accessToken',
            'tokenAccessLifetime' => 3600 * 24,
            'storageMap' => [
                'user_credentials' => 'restapi\modules\v1\models\ApiUser',
                'public_key' => 'restapi\storage\PublicKeyStorage',
                'access_token' => 'restapi\storage\JwtAccessToken',
            ],
            'grantTypes' => [
                'user_credentials' => [
                    'class' => 'OAuth2\GrantType\UserCredentials',
                ],
                'refresh_token' => [
                    'class' => 'OAuth2\GrantType\RefreshToken',
                    'always_issue_new_refresh_token' => true
                ]
            ]
        ]
    ],

Also tried checking out the last commit to 2.0.1 (#44aa6091ce128c9fd0e81c684044a6b57fbfc8eb)

Did this fix in main.php for user_credentials error foreach($this->storageMap as $name => $class) { $storages[$name] = \Yii::$container->get($class); }

But get Invalid grant types configuration for refresh_token because default storage mappings aren't in there. @mtangoo I saw you took that out in earlier commit.

@mtangoo is your jwt working with dev-master? I don't know what the issue is here.

[danDanV1]

Ok. My bad. So dev-master has some issues.

I checked out the 2.0.1 branch and JWT is stable and working. No more user_credentials error.

Solution if anyone else is looking: "filsh/yii2-oauth2-server": "2.0.1.x-dev@dev"

Would be desirable if there was a note about this in the 2.0.0 readme that's default when visiting this repo.

[mtangoo]

Sorry I have been busy. I think the old branches need to be wiped out of existence. 2.0.1.x-dev ought to be dev-master and out of it come some release.

Am not the author of the extension and have no access to repo, so can't do changes.

I think I will re-write the extension IF I happen to get free time.

I was experimenting with something here and its not hard to do that https://github.com/hosannahighertech/upendo

[danDanV1]

That's good to know that I'm on the right branch now. Should be helpful if anyone else finds this thread in the mean time. Thanks for clearing that up @mtangoo

[rlmckenney]

So I used

"filsh/yii2-oauth2-server": "2.0.1.x-dev@dev"

as outlined by @edeis53 above, but I am still getting the dreaded "Class user_credentials does not exist" error. Did you make any other configuration changes?

[danDanV1]

Worked for me. "filsh/yii2-oauth2-server": "2.0.1.x-dev@dev", You might need to check the readme for that branch, I think it may be different from the master as I recall as part of my confusion. Follow that you should be fine. I am using JWT tokens as well.

[mtangoo]

@rlmckenney did you run composer update? Ca you post composer.json file?

[rlmckenney]

I am not using JWT yet. I wanted to get the base config working. When I ran composer update I got ...

and the modules section from my config file is ...

        'oauth2' => [
            'class' => 'filsh\yii2\oauth2server\Module',

            'storageMap' => [

            ],
            'grantTypes' => [
//                'client_credentials' => [
//                    'class' => 'OAuth2\GrantType\ClientCredentials',
//                    'allow_public_clients' => false
//                ],
                'user_credentials' => [
                    'class' => 'OAuth2\GrantType\UserCredentials',
                ],
                'refresh_token' => [
                    'class' => 'OAuth2\GrantType\RefreshToken',
                    'always_issue_new_refresh_token' => true
                ]
            ]
        ],
        'v2' => [
            'basePath' => '@app/versions/v2',
            'class' => 'api\versions\v2\Module'
        ],

I am rechecking the README but I don't think that I missed anything.

[rlmckenney]

I have tried enabling JWT with

            'useJwtToken' => true,
            'storageMap' => [
                'user_credentials' => 'api\common\models\User',
                'public_key' => 'api\storage\PublicKeyStorage',
                'access_token' => 'OAuth2\Storage\JwtAccessToken',
            ],

and I still have the same problem. What am I missing?

[rlmckenney]

After reading the code and some further experimentation, I was able to get things working. Here is what I did ...

1. Use "filsh/yii2-oauth2-server": "2.0.1.x-dev@dev" in my composer.json as discussed above.
2. Update \filsh\yii2\oauth2server\Module.php at line 104 to replace

foreach(array_keys($this->storageMap) as $name) {
    $storages[$name] = \Yii::$container->get($name);
}

with

foreach ($this->storageMap as $name => $class) { 
    $storages[$name] = \Yii::$container->get($class);
}

1. Add the following methods to the User class so that it implements the \OAuth2\Storage\ClientCredentialsInterface

    /**
     * @inheritdoc
     */
    private function getClient($client_id)
    {
        return \filsh\yii2\oauth2server\models\OauthClients::findOne(['client_id' => $client_id]);
    }

    /**
     * @inheritdoc
     */
    public function getClientDetails($client_id)
    {
        $client = $this->getClient($client_id);
        if (empty($client)) return [];

        return [
            "redirect_uri" => $client->redirect_uri,      // REQUIRED redirect_uri registered for the client
            "client_id"    => $client->client_id,         // OPTIONAL the client id
            "grant_types"  => $client->grant_types,       // OPTIONAL an array of restricted grant types
            "user_id"      => $client->user_id,           // OPTIONAL the user identifier associated with this client
            "scope"        => $client->scope,             // OPTIONAL the scopes allowed for this client
        ];
    }

    /**
     * @inheritdoc
     */
    public function getClientScope($client_id)
    {
        $client = $this->getClient($client_id);
        if (empty($client)) return null;

        return $client->scope;
    }

    /**
     * @inheritdoc
     */
    public function checkRestrictedGrantType($client_id, $grant_type)
    {
        $client = $this->getClient($client_id);
        if (empty($client)) return false;

        $validGrantTypes = explode(" ", $client->grant_types);
        return in_array($grant_type, $validGrantTypes);
    }

    /**
     * @inheritdoc
     */
    public function checkClientCredentials($client_id, $client_secret = null)
    {
        $client = $this->getClient($client_id);
        if (empty($client)) return false;

        return ($client->client_secret == $client_secret);
    }

    /**
     * @inheritdoc
     */
    public function isPublicClient($client_id)
    {
        return true;
    }

1. Update the modules section of main config to add 'client_credentials' => 'api\common\models\User', to storageMap and remove refresh_token from grantTypes.

    'modules' => [
        'oauth2' => [
            'class' => 'filsh\yii2\oauth2server\Module',
            'tokenParamName' => 'accessToken',
            'tokenAccessLifetime' => 3600 * 3,
            'useJwtToken' => true,
            'storageMap' => [
                'client_credentials' => 'api\common\models\User',
                'user_credentials' => 'api\common\models\User',
                'public_key' => 'api\storage\PublicKeyStorage',
                'access_token' => 'OAuth2\Storage\JwtAccessToken',
            ],
            'grantTypes' => [
//                'client_credentials' => [
//                    'class' => 'OAuth2\GrantType\ClientCredentials',
//                    'allow_public_clients' => false
//                ],
                'user_credentials' => [
                    'class' => 'OAuth2\GrantType\UserCredentials',
                ],
//                'refresh_token' => [
//                    'class' => 'OAuth2\GrantType\RefreshToken',
//                    'always_issue_new_refresh_token' => true
//                ]
            ]
        ],

I hope this additional information helps someone else.
