yii2: 如何设置 Access-Control-Allow-Origin header

Question

我有这个 yii2 控制器，我想在其中设置 Access-Control-Allow-Origin: * header

class DoctorController extends ActiveController
{
    public $modelClass = 'api\modules\v1\models\Doctor';

    public function behaviors()
    {

        $behaviors = parent::behaviors();



        $behaviors['access'] = [
            'class' => \yii\filters\AccessControl::className(),
            'rules' => [
                [
                    // All actions
                    'allow' => true,
                    'actions' => ['index', 'view'],
                ],
            ],
        ];

        return $behaviors;
    }
}

请帮忙！

Answer 1

您可以使用这个简单的代码：

header('Access-Control-Allow-Origin: *');

它可能会被添加到您的控制器 action 或控制器的 beforeAction() 或其他用例中（根据您的应用程序 logic/architecture 自行决定）。

我已经通过更新 behaviors() 函数解决了

    public function behaviors()
    {

        $behaviors = parent::behaviors();

        $behaviors['corsFilter'] = [
            'class' => \yii\filters\Cors::className(),
            'cors' => [
                'Origin' => ['*'],
                'Access-Control-Request-Method' => ['GET'], // add more 
                'Access-Control-Request-Headers' => ['*'],
                'Access-Control-Allow-Credentials' => null,
                'Access-Control-Max-Age' => 86400,
            ],
        ];

        $behaviors['access'] = [
            'class' => \yii\filters\AccessControl::className(),
            'rules' => [
                [
                    // All actions
                    'allow' => true,
                    'actions' => ['index', 'view'], // add more
                ],
            ],
        ];

        return $behaviors;
    }
