Swift Authorize.net事务响应错误

Question

我正在使用Authorize.net支付api，同时使交易请求收到错误 code = E00001 text =＆＃34;解析值时遇到意外的字符：c。路径＆＃39;＆＃39;，第0行，第0位

如果有人知道要进行交易请求，请帮助： 我使用以下代码：

let json =  """
    {
      "createTransactionRequest": {
        "merchantAuthentication": {
          "name": "",
          "transactionKey": ""
          },
        "refId": "2",
        "transactionRequest": {
          "transactionType": "authCaptureTransaction",
          "amount": "\(totalAmount)",
        "payment": {
          "opaqueData": {
            "dataDescriptor": "\(inResponse.getOpaqueData().getDataDescriptor())",
            "dataValue": "\(inResponse.getOpaqueData().getDataValue())"
            }
          }
        }
      }
    }
    """

    let jsonData = Data(json.utf8)
    do {
      let transaction = try JSONDecoder().decode(Transaction.self, from: jsonData)
      print(transaction)
      // encoding
      let encodedData = try JSONEncoder().encode(transaction)
      print(String(data: encodedData, encoding: .utf8)!)

      //Data to [String : Any]
      do {
        let params = try JSONSerialization.jsonObject(with: encodedData, options: []) as! [String: Any]
        print(params)
        Alamofire.request(“https://apitest.authorize.net/xml/v1/request.api”, method: .post, parameters: params).responseJSON {response in
          print(response)
        }
      } catch {
        print(error)
      }
