前面，我们使用braintree提供的 Drop-in UI，填写完信用卡信息，提交到braintree后，
paymentMethodNonce是由客户端SDK返回的字符串， 返回nonce。它是对客户在付款表格中提供的付款信息的一次性使用参考。
在下一步中，我们将设置您的服务器以接收此字符串，以便可以将其用于创建交易请求
处理结帐
现在，已将客户端设置为安全地收集付款信息，我们将在您的服务器上创建一条路由，该路由接受paymentMethodNonceDrop-in UI中的，然后使用该随机数创建N美元的销售交易请求。
注意：结算之前要先生成magento的订单，当然也可以结算完成后再生成magento订单，braintree以transaction id 作为关联

添加结账方法：braintreeCreditCardPayment()

}submitForSettlement 等于true，则代表结算后自动提交付款申请，直接完成结算。但是如果你在结算前，需要针对这笔交易做一些风险方面的处理，希望通过风险审核后再收款的话，那就把此参数改为false，然后走submitForSettlement方法
