尝试在Controllers加入behaviors()，未能解决。

public function behaviors()
{
    return ArrayHelper::merge([
        [
            'class' => Cors::className(),
            'cors' => [
                'Origin' => ['*'],
                'Access-Control-Request-Method' => ['*'],
                'Access-Control-Allow-Credentials' => true,
            ],
        ],
    ], parent::behaviors());
}

尝试在入口文件加入，未能解决。

header("Access-Control-Allow-Origin: *");
header('Access-Control-Allow-Headers:Authorization');
header("Access-Control-Allow-Methods: GET, POST, DELETE");
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Headers: Content-Type, X-Requested-With, Cache-Control,Authorization");

1.`$response->headers->set('Access-Control-Allow-Origin', '*');

            $response->headers->set('Access-Control-Allow-Methods', 'GET,POST,OPTIONS');
            $response->headers->set('Access-Control-Request-Headers', 'Origin,X-Requested-With, Content-Type, Accept, Token');
            $response->headers->set('Access-Control-Expose-Headers', 'token');
            $response->headers->set('Access-Control-Allow-Headers', 'token');
            if (Yii::$app->request->getMethod() == 'OPTIONS') {
                $response->setStatusCode(200);
            }`

2.有token验证的话
`public function behaviors()

{
    $behaviors = ArrayHelper::merge(parent::behaviors(), [
        'authenticator' => [
            'class' => QueryParamAuth::className(),
            'tokenParam' => 'token',
        ]
    ]);
    $auth = $behaviors['authenticator'];
    unset($behaviors['authenticator']);
    $behaviors['corsFilter'] = [
        'class' => \yii\filters\Cors::className(),
    ];
    $behaviors['authenticator'] = $auth;
    $behaviors['authenticator']['except'] = ['options'];
    return $behaviors;
}`

亲测可用
header('Access-Control-Allow-Origin:');
header('Access-Control-Allow-Methods:');
header('Access-Control-Expose-Headers:*');
header('Access-Control-Allow-Headers:x-requested-with,content-type,token');

最简单的就是在前端域名上配置一个反向代理, 所有指向api的请求通通转发到你后端域名进行处理

这样写

public function behaviors()
{
    return ArrayHelper::merge([
        [
            'class' => Cors::className(),
            'cors' => [
                'Origin' => ['*'],
                'Access-Control-Request-Method' => ['GET', 'POST', 'HEAD', 'OPTIONS'],

            ],
        ],
    ], parent::behaviors());
}
