Webhook在Authorize.Net中始终失败的身份验证

Question

在Authorize.Net中，使用webhook创建了订阅和重复事件处理。当我使用Web钩子帐户进行测试时，身份验证有效，但是在实际的Webhook通知中，身份验证始终失败

if (isset($this->header['x-anet-signature'])) {
        $json = Json::encode($this->body);
        if ($json) {
            //To check the header and signature is true
         if (hash_equals(strtolower($this->header['x-anet-signature']),
                    'sha512=' . hash_hmac('sha512',$json, $secret))
            ) { 


             }else{
                yii::info($json,'webhookhNotifications');
                throw new \yii\web\ServerErrorHttpException('Authentication failed in Webhook');
              return false;

            } 
        }
    }

Webhook JSON

{
   "notificationId":"4bbba8fb-1d32-46b6-a513-a9ca2fed885c",
   "eventType":"net.authorize.customer.subscription.created",

Answer 1

您的代码应该有效。我出于测试目的对其做了一些简化，但是使用上面提供的值确实可以成功验证：

$signature = 'sha512=FDE5518801C115C4886311877B4C37F6C26ABACE01ADB973EF372FB51C8F1E5321A83717161AD7DEFFD46F5013900E68B6220F3B25E9302A4208A9C673D32749';
$json = '{"notificationId":"4bbba8fb-1d32-46b6-a513-a9ca2fed885c","eventType":"net.authorize.customer.subscription.created","eventDate":"2019-11-27T06:20:36.3621687Z","webhookId":"a2929d59-147e-4400-a2bb-b3bd25a0311d","payload":{"name":"Test subscription","amount":290.00,"status":"active","profile":{"customerProfileId":1921894828,"customerPaymentProfileId":1834842681,"customerShippingAddressId":1879009509},"entityName":"subscription","id":"6168233"}}';
$secret = 'F7B582AFFA9372866965456CFAC0D1B1219258F955FD5266D1A96BF9BE3C85F7D54C7CDFF9EF3EE7D3916EACB5EE920167F557BBB307288C17FBD169F0257AB4';

if (hash_equals(strtolower($signature), 'sha512=' . hash_hmac('sha512', $json, $secret))) {
    echo 'valid';
}else{
    echo 'invalid';
}

Demo

[我认为您的错误是您正在编码已经为JSON的JSON。因此删除此行：

$json = Json::encode($this->body);

新代码：

if (isset($this->header['x-anet-signature'])) {
        $json = $this->body;
        if ($json) {
            //To check the header and signature is true
         if (hash_equals(strtolower($this->header['x-anet-signature']),
                    'sha512=' . hash_hmac('sha512',$json, $secret))
            ) { 


             }else{
                yii::info($json,'webhookhNotifications');
                throw new \yii\web\ServerErrorHttpException('Authentication failed in Webhook');
              return false;

            } 
        }
    }
