BrainTree Sandbox返回验证错误:-未知paymentMethodNonce - BrainTree Sandbox returns Validation errors: - Unknown paymentMethodNonce

我正在将Brainstree集成到一个网站中

从沙箱开始。。。。

客户端：

    });
</script>

对于服务器：

 <?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/>");
    }
}

当它返回时：

 Validation errors: - Unknown paymentMethodNonce.

这是直接从教程中提取的代码-太困惑了，我做错了

这是一个仅限网站（无应用程序）的服务

目前还不完全清楚您在JS中使用了哪个客户端令牌，在PHP中使用了哪些商家凭据，但我认为这可能是问题所在。

支付方法随机数是特定于商家的，并且客户端令牌在代表特定商家的有限权限下初始化Drop-In UI。如果您使用的是上面粘贴的实际客户端令牌，则该商户就是我们的沙盒演示商户。

你需要在PHP示例顶部的字段中替换你自己的沙盒商家的商家ID、公钥和私钥（我想你已经替换了，只是把它们拿出来发布）。在构建显示UI的页面时，您还需要在PHP中调用Braintree:：ClientToken.generate，以便在该页面中添加商家的真实客户端令牌。看见https://developers.braintreepayments.com/javascript+php/start/hello-server#provide-a-client-to-ken-to-our-client。

请随时联系Braintree支持support@braintreepayments.comsupport@braintreepayments.comif你需要更多的帮助。

您应该传递一个有效的nonce。eq：伪造的有效nonce。

其他有效的nonce在braintree页面链接
