Question

我想使用离子3复制一个braintree演示应用程序。

我用...导入了braintree import * as braintree from 'braintree';

但我无法连接到braintree。

消息读取...“运行时错误：类扩展值[object Object]不是构造函数或null”

这是我的ts文件中的代码

import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams, ViewController } from 'ionic-angular';

import * as braintree from 'braintree';

@IonicPage()
@Component({
  selector: 'page-apply',
  templateUrl: 'apply.html',
})

export class ApplyPage {

  gateway: any;

  constructor(public navCtrl: NavController, public navParams: NavParams, public viewCtrl: ViewController) {
    this.gateway = braintree.connect({
      environment:  braintree.Environment.Sandbox,
      merchantId:   'personalMerchantId',
      publicKey:    'personalPublicKey',
      privateKey:   'personalPrivateKey'
    });
  }

  ionViewDidLoad() {
    console.log('ionViewDidLoad ApplyPage');
  }


}

这是模块的index.js文件中的代码

'use strict';

module.exports = require('./lib/braintree');

此代码位于braintree.js文件中，index.js指向

'use strict';

let version = require('../package.json').version;
let Config = require('./braintree/config').Config;
let Environment = require('./braintree/environment').Environment;
let BraintreeGateway = require('./braintree/braintree_gateway').BraintreeGateway;
let errorTypes = require('./braintree/error_types').errorTypes;

let Transaction = require('./braintree/transaction').Transaction;

let CreditCard = require('./braintree/credit_card').CreditCard;
let PayPalAccount = require('./braintree/paypal_account').PayPalAccount;
let AndroidPayCard = require('./braintree/android_pay_card').AndroidPayCard;
let ApplePayCard = require('./braintree/apple_pay_card').ApplePayCard;
let VenmoAccount = require('./braintree/venmo_account').VenmoAccount;
let CoinbaseAccount = require('./braintree/coinbase_account').CoinbaseAccount;
let AmexExpressCheckoutCard = require('./braintree/amex_express_checkout_card').AmexExpressCheckoutCard;
let VisaCheckoutCard = require('./braintree/visa_checkout_card').VisaCheckoutCard;
let MasterpassCard = require('./braintree/masterpass_card').MasterpassCard;

let CreditCardVerification = require('./braintree/credit_card_verification').CreditCardVerification;
let Subscription = require('./braintree/subscription').Subscription;
let MerchantAccount = require('./braintree/merchant_account').MerchantAccount;
let PaymentInstrumentTypes = require('./braintree/payment_instrument_types').PaymentInstrumentTypes;
let WebhookNotification = require('./braintree/webhook_notification').WebhookNotification;
let TestingGateway = require('./braintree/testing_gateway').TestingGateway;
let ValidationErrorCodes = require('./braintree/validation_error_codes').ValidationErrorCodes;

let CreditCardDefaults = require('./braintree/test/credit_card_defaults').CreditCardDefaults;
let CreditCardNumbers = require('./braintree/test/credit_card_numbers').CreditCardNumbers;
let MerchantAccountTest = require('./braintree/test/merchant_account').MerchantAccountTest;
let Nonces = require('./braintree/test/nonces').Nonces;
let TransactionAmounts = require('./braintree/test/transaction_amounts').TransactionAmounts;

let connect = config => new BraintreeGateway(new Config(config)); // eslint-disable-line func-style
let Test = {
  CreditCardDefaults: CreditCardDefaults,
  CreditCardNumbers: CreditCardNumbers,
  MerchantAccountTest: MerchantAccountTest,
  Nonces: Nonces,
  TransactionAmounts: TransactionAmounts
};

module.exports = {
  connect: connect,
  version: version,
  Environment: Environment,
  errorTypes: errorTypes,

  Transaction: Transaction,

  CreditCard: CreditCard,
  PayPalAccount: PayPalAccount,
  AndroidPayCard: AndroidPayCard,
  ApplePayCard: ApplePayCard,
  VenmoAccount: VenmoAccount,
  CoinbaseAccount: CoinbaseAccount,
  AmexExpressCheckoutCard: AmexExpressCheckoutCard,
  VisaCheckoutCard: VisaCheckoutCard,
  MasterpassCard: MasterpassCard,

  CreditCardVerification: CreditCardVerification,
  Subscription: Subscription,
  MerchantAccount: MerchantAccount,
  PaymentInstrumentTypes: PaymentInstrumentTypes,
  WebhookNotification: WebhookNotification,
  TestingGateway: TestingGateway,
  ValidationErrorCodes: ValidationErrorCodes,

  Test: Test
};

这是代码，它位于工作ExpressJs Demo的index.js文件中

var express = require('express');
var router = express.Router();
var braintree = require('braintree');

var gateway = braintree.connect({
    environment:  braintree.Environment.Sandbox,
    merchantId:   'personalMerchantID',
    publicKey:    'personalPublicKey',
    privateKey:   'personal_PrivateKey'
});

router.get('/', function(req, res) {
  gateway.clientToken.generate({}, function(err, response) {
    var token = response.clientToken;

    res.render('index', {token : token});
  });
});

router.post('/add', function(req, res) {

  var merchant_id = req.body.merchant_id;
  var bank_account = req.body.bank_account;
  var bank_routing = req.body.bank_routing;

  var merchantAccountParams = {
    individual: {
      firstName: "Jane",
      lastName: "Doe",
      email: "jane@14ladders.com",
      phone: "5553334444",
      dateOfBirth: "1981-11-19",
      ssn: "456-45-4567",
      address: {
        streetAddress: "111 Main St",
        locality: "Chicago",
        region: "IL",
        postalCode: "60622"
      }
    },
    funding: {
      destination: braintree.MerchantAccount.FundingDestination.Bank,
      accountNumber: bank_account,
      routingNumber: bank_routing
    },
    tosAccepted: true,
    masterMerchantAccountId: "_my_personal_master_merchant_account_ID",
    id: merchant_id
  };

  gateway.merchantAccount.create(merchantAccountParams, function (err, result) {
    res.render('addResult', {result: result});
  });

});

router.get('/find', function(req, res) {
  var merchant_id = req.query.merchant_id;

  gateway.merchantAccount.find(merchant_id, function(err, result) {
    res.render('findResult', {result: result, merchant_id: merchant_id});
  });

});

router.post('/process', function(req, res) {
  var nonce = req.body.payment_method_nonce;
  var total = req.body.total;
  var service = req.body.service;
  var merchant_id = req.body.merchant_id;

  gateway.transaction.sale({
    amount: total,
    merchantAccountId: merchant_id,
    paymentMethodNonce: nonce,
    serviceFeeAmount: service
  }, function (err, result) {
    res.render('processResult', {result: result});
  });
});

module.exports = router;

上面的代码再次由braintree制作。我确定只是为了演示目的。

Answer 1

你不应该这样做。

通过在移动客户端中包含Braintree节点服务器库，您将向使用该应用程序的任何人公开您的私钥。这是非常不安全的。

相反，您应该有一台服务器，您可以接受应用生成的nonce来处理事务。 @Sampath发布的Braintree Cordova插件看起来是在您的应用中生成随机数的合理方式。

Answer 2

您似乎没有使用上述实施的任何插件。所以你必须使用一个。这是Braintree Cordova Plugin。

npm install plist
npm install xcode

cordova platform remove ios
cordova plugin add https://github.com/taracque/cordova-plugin-braintree
cordova platform add ios

在这里，您可以了解如何将none native plugin添加到Ionic应用。
