Question

当我使用filsh / yii2-oauth2-server在yii2上构建oauth2 restful api时。它总是返回401。

控制器中的验证码

/**
 * @return array
 */
public function behaviors()
{
    return ArrayHelper::merge(parent::behaviors(), [
        'authentication' => [
            'class' => CompositeAuth::class,
            'authMethods' => [
                ['class' => HttpBasicAuth::class],
                ['class' => HttpBearerAuth::class],
                ['class' => QueryParamAuth::class, 'tokenParam' => 'accessToken'],
            ],
        ],
        'exceptionFilter' => [
            'class' => ErrorToExceptionFilter::class
        ]
    ]);
}

配置文件中的代码

'oauth2' => [
    'class' => \filsh\yii2\oauth2server\Module::class,
    'components' => [
        'request' => function () {
            return \filsh\yii2\oauth2server\Request::createFromGlobals();
        },
        'response' => [
            'class' => \filsh\yii2\oauth2server\Response::class,
        ],
    ],

    'tokenParamName' => 'accessToken',
    'tokenAccessLifetime' => 3600 * 24 * 7,
    'storageMap' => [
        'user_credentials' => 'common\models\User',
    ],
    'grantTypes' => [
        'user_credentials' => [
            'class' => 'OAuth2\GrantType\UserCredentials',
        ],
        'refresh_token' => [
            'class' => 'OAuth2\GrantType\RefreshToken',
            'always_issue_new_refresh_token' => true
        ]
    ],
],

用户模型中的代码

/**
 * {@inheritdoc}
 */
public static function findIdentityByAccessToken($token, $type = null)
{
    /** @var \filsh\yii2\oauth2server\Module $module */
    $module = Yii::$app->getModule('oauth2');
    $token = $module->getServer()->getResourceController()->getToken();
    return !empty($token['user_id'])
        ? static::findIdentity($token['user_id'])
        : null;
}

Get access_token

Request test

我的尝试

当我尝试查找问题时，我在用户模型中找到了问题。

$token = $module->getServer()->getResourceController()->getToken();

总是返回NULL，我不知道这是原因还是如何解决？
