问题描述
我已经搜索了好几个小时,希望这里有人能提供帮助。 我使用PayPal PHP SDK在Laravel和PayPal订阅上构建了一个基于订阅的网站。 除了在以下方面,一切都可以完美运行: 当用户取消付款时,我创建了一个Webhook。我收到此错误:
Got Http response code 400 when accessing https://api.sandBox.paypal.com/v1/notifications/verify-webhook-signature.{"name":"VALIDATION_ERROR","message":"Invalid data provided","debug_id":"7225cebfec35a","information_link":"https://developer.paypal.com/docs/api/webhooks/#errors","details":[{"field":"webhook_id","location":"body","issue":"required field cannot be blank"}],"links":[]}
这是我的代码:
public function webhook()
{
/**
* Receive the entire body that you received from PayPal webhook.
*/
$bodyReceived = file_get_contents('PHP://input');
// Receive HTTP headers that you received from PayPal webhook.
$headers = getallheaders();
/**
* Uppercase all the headers for consistency
*/
$headers = array_change_key_case($headers,CASE_UPPER);
$signatureVerification = new \PayPal\Api\VerifyWebhookSignature();
$signatureVerification->setWebhookId(env('PAYPAL_WEBHOOK_ID'));
$signatureVerification->setAuthAlgo($headers['PAYPAL-AUTH-ALGO']);
$signatureVerification->setTransmissionId($headers['PAYPAL-TRANSMISSION-ID']);
$signatureVerification->setCertUrl($headers['PAYPAL-CERT-URL']);
$signatureVerification->setTransmissionSig($headers['PAYPAL-TRANSMISSION-SIG']);
$signatureVerification->setTransmissionTime($headers['PAYPAL-TRANSMISSION-TIME']);
$webhookEvent = new \PayPal\Api\WebhookEvent();
$webhookEvent->fromJson($bodyReceived);
$signatureVerification->setWebhookEvent($webhookEvent);
$request = clone $signatureVerification;
try {
$output = $signatureVerification->post($this->apiContext);
} catch(\Exception $ex) {
//This is where it fails
print_r($ex->getMessage());
exit(1);
}
$verificationStatus = $output->getVerificationStatus();
$responseArray = json_decode($request->toJSON(),true);
$event = $responseArray['webhook_event']['event_type'];
if ($verificationStatus == 'SUCCESS')
{
switch($event)
{
case 'BILLING.SUBSCRIPTION.CANCELLED':
case 'BILLING.SUBSCRIPTION.SUSPENDED':
case 'BILLING.SUBSCRIPTION.EXPIRED':
case 'BILLING_AGREEMENTS.AGREEMENT.CANCELLED':
// $user = User::where('payer_id',$responseArray['webhook_event']['resource']['payer']['payer_info']['payer_id'])->first();
$this->updateStatus($responseArray['webhook_event']['resource']['payer']['payer_info']['payer_id'],1);
break;
}
}
echo $verificationStatus;
exit(0);
}
这是$this->apiContext
:
trait PayPalApiCredentialsTrait {
private $apiContext;
public function setCredentials()
{
$this->apiContext = new \PayPal\Rest\ApiContext(
new \PayPal\Auth\OAuthTokenCredential(
env('PAYPAL_CLIENT_ID'),// ClientID
env('PAYPAL_CLIENT_SECRET') // ClientSecret
)
);
$this->apiContext->setConfig(
array(
'mode' => env("PAYPAL_MODE"),'log.LogEnabled' => true,'log.FileName' => '../PayPal.log','log.LogLevel' => 'INFO',// PLEASE USE `INFO` LEVEL FOR LOGGING IN LIVE ENVIRONMENTS
)
);
}
}
这是我从paypal.log中得到的错误:
[01-09-2020 15:54:18] PayPal\Core\PayPalhttpconnection : INFO: POST https://api.sandBox.paypal.com/v1/oauth2/token

我必须提到,其他所有功能都可以正常工作。 创建计划,协议,同时取消两者,显示有效计划等... 一切顺利。 这是我似乎无法解决的唯一问题。 如果有人能为我解决这个问题,我将非常感激。 谢谢!
解决方法
不建议使用PayPal-PHP-SDK,并且不再对其进行维护;它不应用于新的集成。它的计费计划和订阅的实现较旧,并且与当前版本的Subscriptions API不兼容。
应使用直接HTTPS集成(无SDK)来进行订阅和验证Webhook。
(对于一次性付款用例,有一个新的v2 Checkout-PHP-SDK https://developer.paypal.com/docs/api/rest-sdks/)
