BrainTree沙箱返回驗證錯誤：-未知paymentMethodNonce

Question

我正在將Braintree集成到網站中

從沙盒開始...

客戶端：

   <form id="checkout" method="post" action="payments.php">
  <div id="dropin"></div>
  <input type="submit" value="Pay $10">
</form>

<script src="https://js.braintreegateway.com/v2/braintree.js"></script>

<script>
  braintree.setup(

</script>

對於服務器：

 <?php
include("braintree/Braintree.php"); 

Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('');
Braintree_Configuration::publicKey('');
Braintree_Configuration::privateKey('');

$nonce = $_POST["payment_method_nonce"];

$result = Braintree_Transaction::sale(array(
  'amount' => '100.00',
  'paymentMethodNonce' => $nonce
));


if ($result->success) {
    echo("Success! Transaction ID: " . $result->transaction->id);
} else if ($result->transaction) {
    echo("Error: " . $result->message);
    echo("<br/>");
    echo("Code: " . $result->transaction->processorResponseCode);
} else {
    echo("Validation errors:<br/>");
    foreach (($result->errors->deepAll()) as $error) {
        echo("- " . $error->message . "<br/>");
    }
}

當它返回時：

 Validation errors: - Unknown paymentMethodNonce.

這是直接從教程中獲取的代碼-如此困惑我做錯了什么

這是僅網站（無應用程序）服務

Answer 1

目前尚不清楚您在JS中使用了哪個客戶端令牌以及在PHP中使用了哪個商家憑據，但是我認為這可能是問題所在。

支付方式隨機數是特定於商家的，並且客戶令牌會使用代表特定商家的有限權限來初始化Drop In UI。 如果您使用上面粘貼的實際客戶令牌，則該商人是我們的沙盒演示商人。

您需要在PHP示例頂部的字段中替換自己的沙盒商人的商人ID，公共密鑰和私有密鑰（我假設您已經這樣做，只是將它們拿出來進行發布）。 在構建顯示UI的頁面時，您還需要在PHP中調用Braintree :: ClientToken.generate，以便可以向該頁面添加商家的真實客戶令牌。 請參閱https://developers.braintreepayments.com/javascript+php/start/hello-server#provide-a-client-token-to-your-client 。

如果您需要更多幫助，請隨時通過support@braintreepayments.com support@braintreepayments.com與Braintree支持聯系。

您應該傳遞有效的隨機數。 EQ：假化有效的隨機數。

其他有效的隨機數在braintree頁面鏈接中
