Question

我正在尝试从Webhook验证签名，如下所示：

require_once('vendor/autoload.php');

use \PayPal\Api\VerifyWebhookSignature;
use \PayPal\Api\WebhookEvent;
use \PayPal\Api\VerifyWebhookSignatureResponse;

$apiContext = require __DIR__ . '/bootstrap.php';

$bodyReceivedJson = file_get_contents('php://input');
$bodyDecoded = json_decode($requestBodyJson, true);

$headers = getallheaders();
$headers = array_change_key_case($headers, CASE_UPPER);

$signatureVerification = new VerifyWebhookSignature();
$signatureVerification->setAuthAlgo($headers['PAYPAL-AUTH-ALGO']);
$signatureVerification->setTransmissionId($headers['PAYPAL-TRANSMISSION-ID']);
$signatureVerification->setCertUrl($headers['PAYPAL-CERT-URL']);
$signatureVerification->setWebhookId("55555555555555555");
$signatureVerification->setTransmissionSig($headers['PAYPAL-TRANSMISSION-SIG']);
$signatureVerification->setTransmissionTime($headers['PAYPAL-TRANSMISSION-TIME']);

$signatureVerification->setRequestBody($bodyReceivedJson);
$request = clone $signatureVerification;

try{
  $output = $signatureVerification->post($apiContext);
}
catch (Exception $ex){
  exit(1);
}

但是我收到此错误：

[26-Oct-2019 20:18:16 UTC] PHP Fatal error:  Uncaught TypeError: Argument 1 passed to PayPal\Transport\PayPalRestCall::__construct() must be an instance of PayPal\Rest\ApiContext, int given, called in C:\vendor\paypal\rest-api-sdk-php\lib\PayPal\Common\PayPalResourceModel.php on line 101 and defined in C:\vendor\paypal\rest-api-sdk-php\lib\PayPal\Transport\PayPalRestCall.php:38

我不知道此错误试图告诉我什么。

$ request（已修改的ID和我不确定是否应该共享的内容）：

Answer 1

结果是：

$apiContext = require __DIR__ . '/bootstrap.php';

实际上没有得到所需的东西：

  $apiContext  = new \PayPal\Rest\ApiContext(
    new \PayPal\Auth\OAuthTokenCredential(
      'YOUR APPLICATION CLIENT ID'
      'YOUR APPLICATION CLIENT SECRET'
    )
  );

无法验证Webhook签名PHP
