php - PHP 中的 Swish 支付 API

问题描述

Swish 是瑞典的支付提供商。您只需向电话号码汇款即可付款。

这是 Swish 提供的新 PAYOUT 服务的 API。与 PAYMENT 服务不同，因此请不要混淆。

他们的网站上没有可用的 PHP 示例，我无法获得 200 响应。

如果您的专业人士可以帮助我解决这个问题，我认为将来还有很多其他人可以从该解决方案中受益。

所以这是我当前的代码。

$payload = [
  "payoutInstructionUUID" => "E4D773858AF5459B96ABCA4B9DBFF94D",
  "payerPaymentReference" => "payerRef",
  "payerAlias" => "1231388446",
  "payeeAlias" => "46712345678",
  "payeeSSN" => "198602111638",
  "amount" => "100.00",
  "currency" => "SEK",
  "payoutType" => "PAYOUT",
  "message" => "Message to the recipient.",
  "instructionDate" => carbon::now(),
  "signingCertificateSerialNumber" => "667A2C6E068B76988AB657351F5AF636"
];

$pkey =     openssl_pkey_get_private(file_get_contents('Swish_Merchant_TestSigningCertificate_1234679304.key'), 'swish');
$payloadHash =  hash('sha512', json_encode($payload));


$signature =   openssl_sign($payloadHash, $signature, $pkey) ? base64_encode($signature) : null;


 $request = [
  "payload" => $payload,
  "callbackUrl" => "https://postb.in/1634560192746-3820346647407",
  "signature" => $signature 
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://mss.cpc.getswish.net/swish-cpcapi/api/v1/payouts');
curl_setopt($ch, CURLOPT_PORT, 443);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSLCERT, 'Swish_Merchant_TestCertificate_1234679304.p12');
curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'P12');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'swish');
curl_setopt($ch, CURLOPT_SSLKEY, 'Swish_Merchant_TestCertificate_1234679304.key');
curl_setopt($ch, CURLOPT_SSLKEYPASSWD, 'swish');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_CAINFO, 'Swish_TLS_RootCA.pem');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSLVERSION, 6);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);


curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($request));
$f = tmpfile();
curl_setopt($ch, CURLOPT_STDERR, $f);
 $results = curl_exec($ch);

fseek($f, 0);
echo "Verbose information:\n<pre>", fread($f, 32 * 1024), "</pre>\n";
fclose($f);

$info =curl_errno($ch)>0 ? array("curl_error_".curl_errno($ch)=>curl_error($ch)) : curl_getinfo($ch);
print_r($info);

curl_close($ch);

如您所见，响应不是很准确，告诉我出了什么问题。我尝试将签名更改为一些随机数，但仍然收到相同的错误消息。这让我相信签名不正确。

测试环境无需注册。您可以在自己的计算机上进行测试。

解决方案

尝试改变

$signature =   openssl_sign($payloadHash, $signature, $pkey) ? base64_encode($signature) : null;

至

$signature =   openssl_sign($payloadHash, $signature, $pkey, OPENSSL_ALGO_SHA512) ? base64_encode($signature) : null;
