集成Braintree php时出错 - Error while integrating Braintree php

我在我的codeigniter项目中使用braintree来处理信用卡支付，并且braintree_Transaction:：sale抛出无效参数异常，称账单地址参数的密钥无效消息。但我不认为有任何验证错误。我想做的事情可以简化为：

$card_info = [
      'cardholderName' =>mysql_real_escape_string($_POST['full_name']),
      'number' =>mysql_real_escape_string($_POST['number']),
      'expirationMonth' =>mysql_real_escape_string($_POST['expiry_month']),
      'expirationYear' =>mysql_real_escape_string($_POST['expiry_year']),
      'cvv' =>mysql_real_escape_string($_POST['card_cvv']),
      'billingAddress' =[
              'firstName' =>mysql_real_escape_string($_POST['first_name']),
              'lastName'=>mysql_real_escape_string($_POST['last_name']),
              'streetAddress'=>mysql_real_escape_string($_POST['user_address']),
              'city'=>mysql_real_escape_string($_POST['user_city']),
              'state'=>mysql_real_escape_string($_POST['user_state']),
              'country' =>mysql_real_escape_string($_POST['user_country']),
                ]
       ]
       $result = Braintree_Transaction::sale(['amount'=>'4.99',
                                              'creditCard'=>$card_info,
                                              'options'=>['submitForSettlement' => true]
                                              ])

但是当我运行以下代码时，我得到以下错误：

 <br />
 <b>Fatal error</b>:  Uncaught exception 'InvalidArgumentException' with       message 'invalid keys: creditCard[billingAddress][city],   creditCard[billingAddress][country], creditCard[billingAddress][firstName], creditCard[billingAddress][lastName], creditCard[billingAddress][state], creditCard[billingAddress][streetAddress]' in   C:'xampp'htdocs'naya_admin'application'third_party'braintree'lib'Braintree'Util.php:343

Ilan Hasanov是正确的，您需要在交易呼叫中分别传递账单参数和信用卡详细信息。此外，您应该将"city"替换为"locality"，将"state"替换为《region》，将"country"替换为您存储在数据库中的任何国家字段

$billing =[
    'firstName' =>mysql_real_escape_string($_POST['first_name']),
    'lastName'=>mysql_real_escape_string($_POST['last_name']),
    'streetAddress'=>mysql_real_escape_string($_POST['user_address']),
    'locality'=>mysql_real_escape_string($_POST['user_city']),
    'region'=>mysql_real_escape_string($_POST['user_state']),
    'countryName' =>mysql_real_escape_string($_POST['user_country']),
];

此外，为了降低PCI合规性负担，我建议将nonce代替信用卡详细信息传递给服务器。

您需要分离账单地址：

    $card_info = [
    'cardholderName' =>mysql_real_escape_string($_POST['full_name']),
    'number' =>mysql_real_escape_string($_POST['number']),
    'expirationMonth' =>mysql_real_escape_string($_POST['expiry_month']),
    'expirationYear' =>mysql_real_escape_string($_POST['expiry_year']),
    'cvv' =>mysql_real_escape_string($_POST['card_cvv']),
];
$billing =[
    'firstName' =>mysql_real_escape_string($_POST['first_name']),
    'lastName'=>mysql_real_escape_string($_POST['last_name']),
    'streetAddress'=>mysql_real_escape_string($_POST['user_address']),
    'city'=>mysql_real_escape_string($_POST['user_city']),
    'state'=>mysql_real_escape_string($_POST['user_state']),
    'country' =>mysql_real_escape_string($_POST['user_country']),
];
$result = Braintree_Transaction::sale(['amount'=>'4.99',
    'creditCard'=>$card_info,
    'billing' => $billing,
    'options'=>['submitForSettlement' => true]
]);
