我有一个应用程序，我集成了braintree支付网关。我使用自定义表单而不是插入式UI，我使用creditCard参数从客户信用卡进行一次性交易。我最近发现不推荐使用creditCard参数，并且我之前的代码已经引入了新参数 // declaration
String a = "a";
String b = "a";
String c = new String("a");
// check references
System.out.println("AB>>" + (a == b)); // true, a & b references same memory position
System.out.println("AC>>" + (a == c)); // false, a & c are different strings
// as logic states if a == b && a != c then b != c.
// using equals
System.out.println("ACe>" + (a.equals(c))); // true, because compares content!!!!
// using intern()
System.out.println("ABi>" + (a.intern() == b.intern())); // true
System.out.println("BCi>" + (b.intern() == c.intern())); // true
paymentMethodNonce根据文档，我需要使用隐藏的输入字段在表单中发送一个令牌来进行事务，我以下列方式在表单中添加了令牌
Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('xxxxxx');
Braintree_Configuration::publicKey('xxxxxx');
Braintree_Configuration::privateKey('xxxxxxxxxxxxxxxxx');
$result = Braintree_Transaction::sale(array(
'amount' => $price,
'creditCard' => array(
'number' => $card_number,
'cardholderName' => $card_name,
'expirationDate' => $expirationDate,
'cvv' => $cvv
)
));
在我提交表单的另一页上，我使用文档更改了代码，但仍然收到验证错误
付款方式令牌无效。
<input type="hidden" name="payment_method_nonce" id="payment_method_nonce" value="<?=Braintree_ClientToken::generate()?>" />
被修改
这是更新后的代码
的index.php
$payment_method_nonce = $_POST['payment_method_nonce'];
$result = Braintree_Transaction::sale([
'amount' => '25.00',
'paymentMethodToken' => $payment_method_nonce,
'options' => [
'submitForSettlement' => True
]
]);
cardprocess.php
<?php

Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('xxxxxx');
Braintree_Configuration::publicKey('xxxxxxx');
Braintree_Configuration::privateKey('xxxxxx');
$payment_method_nonce= Braintree_ClientToken::generate();

完全披露：我在Braintree工作。如果您有任何其他问题，请随时联系support。
Braintree客户端令牌和付款方式nonce是两个不同的元素。应在您的服务器上生成客户端令牌，并将其用于configure the JavaScript SDK，其中包含令牌和HTML表单的DOM ID;之后，您无需担心自己添加和填充隐藏字段。提交表格后，Braintree会创建一个付款方式nonce，并通过隐藏的输入将其与表单一起发送。
在服务器端，您的代码也需要稍作调整：您当前正在发送paymentMethodToken，它指的是现有付款方式的唯一标识符。 nonce的关键应该是paymentMethodNonce，如credit card guide中所述。
$payment_method_nonce = $_POST['payment_method_nonce'];
$result = Braintree_Transaction::sale([
'amount' => '25.00',
'paymentMethodNonce’ => $payment_method_nonce,
'options' => [
'submitForSettlement' => True
]
]);
