Braintree API:无法确定沙盒交易的付款方式

Ele*_*ova 5 braintree

我目前正在使用沙箱测试 Braintree API。当我将随机数发布到服务器时,我从 Braintree API 收到消息:需要金额。无法确定付款方式。我发现我可以对随机数使用硬编码值: paymentMethodNonce: "fake-valid-nonce" 在这种情况下,我可以在沙箱中看到交易。但我想查看我在嵌入式用户界面中输入的信用卡。出现“无法确定付款方式”消息的原因可能是什么?我的服务器端node.js代码如下:

  var amount = req.body.amount;
  // Use the payment method nonce here
  var nonceFromTheClient = req.body.paymentMethodNonce;

  var newTransaction = gateway.transaction.sale({
                      amount: amount,                      
                      //paymentMethodNonce: "fake-valid-nonce",

                      paymentMethodNonce: nonceFromTheClient,
                      options: {                          
                      submitForSettlement: true }
                      }, function(error, result) {
                      if (result) {
                          res.send(result);
                      } else {                               
                          res.status(500).send(error);
                      }
                   });

我的 Swift 客户端代码:

func sendRequestPaymentToServer(nonce: String, amount: String) {

    let paymentURL = URL(string: "http://localhost:5000/checkout")!
    var request = URLRequest(url: paymentURL)
    request.httpBody = "paymentMethodNonce=\(nonce)&amount=\(amount)".data(using: String.Encoding.utf8)
    request.httpMethod = "POST"

    URLSession.shared.dataTask(with: request) { (data, response, error) -> Void in
        guard let data = data else {
            print(error!.localizedDescription)
            return
        }
        if let result = try? JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] {
            if result?["success"] as? Bool == true {
                print("Successfully charged. Thanks So Much :)")
            }
            else if let message = result?["message"] {
                print(message)
            }
            //dump(result)
        } else {
            print("No json result.")
        }
        }.resume()

问题出在我的正文解析器中 - 它配置不正确。通过以下代码行解决了该问题:

.use(bodyParser.urlencoded({extended: true}))
