RESTfulWeb服务授权认证和Ajax跨域配置问题[2.0]

开发api接口，做了HttpBearerAuth授权登陆之后，ajax请求跨域，我的配置如下：

  public function behaviors()
        {
            return ArrayHelper::merge(parent::behaviors(), [
            // 授权验证
            'authenticator' => [
                'class' => HttpBearerAuth::className(),
                'optional' => [
                    'login',
                    'signup',
                ],
            ],
                'corsFilter'  => [
                    'class' => \yii\filters\Cors::className(),
                    'cors'  => [
                        'Origin' => ['*'],
                        'Access-Control-Request-Headers' => ['authorization'],
                    ],
                ],
        ]);
        }

Ajax请求出现：Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ ；
请路过的兄弟姐妹们看看要如何配置才会不会跨域，

‘Origin’ => [‘*’], * 指定可以跨域的域名即可。

use yii\filters\Cors;
