flutter - 如何在 flutter 中从 Stripe 信用卡获取 token ID

Question

我想从我的信用卡中获取 tokenID。我看到这个 Article正在使用 StripeSource.addSource但是最新的stripe包没有StripeSource.addSource .所以我喜欢这样:

StripePayment.paymentRequestWithCardForm(
 CardFormPaymentRequest())
 .catchError((e) {
 print('ERROR ${e.toString()}');
 }).then((PaymentMethod paymentMethod) async {
  final CreditCard testCard =  CreditCard(
  number: paymentMethod.card.number,
  expMonth: paymentMethod.card.expMonth,
  expYear: paymentMethod.card.expYear
 );

 StripePayment.createTokenWithCard(testCard).then((token) {
  print(token.tokenId);
  });
 });

但我收到错误 Unhandled Exception: PlatformException(invalidRequest, Missing required param: card[number]., null)
任何人都可以帮我解决这个问题吗？谢谢

我喜欢这样:

class _MyHomePageState extends State<MyHomePage> {
  static String secret = 'sk_test_xxxxxxxxxxxxx';

  TextEditingController cardNumberController = new TextEditingController();
  TextEditingController expYearController = new TextEditingController();
  TextEditingController expMonthController = new TextEditingController();

  @override
  initState() {
  super.initState();

  StripePayment.setOptions(
    StripeOptions(publishableKey: "pk_testxxxxxx", merchantId: "Test", androidPayMode: 'test')
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            TextField(
              controller: cardNumberController,
              decoration: InputDecoration(labelText: 'Card Number'),
            ),
            TextField(
              controller: expMonthController,
              keyboardType: TextInputType.number,
              decoration: InputDecoration(labelText: 'Expired Month'),
            ),
            TextField(
              controller: expYearController,
              keyboardType: TextInputType.number,
              decoration: InputDecoration(labelText: 'Expired Year'),
            ),
            RaisedButton(
              child: Text('card'),
              onPressed: () {
               final CreditCard testCard =  CreditCard(
                        number: cardNumberController.text,
                        expMonth: int.parse(expMonthController.text),
                        expYear: int.parse(expYearController.text)
                      );

              StripePayment.createTokenWithCard(testCard).then((token) {
                print(token.tokenId);

                createCharge(token.tokenId);
              });
            },)
          ],
        ),
      ),
    );
  }

  static Future<Map<String, dynamic>> createCharge(String tokenId) async {
    try {
      Map<String, dynamic> body = {
        'amount': '2000',
        'currency': 'usd',
        'source': tokenId,
        'description': 'My first try'
      };
      var response = await http.post(
        'https://api.stripe.com/v1/charges',
        body: body,
        headers: { 'Authorization': 'Bearer ${secret}','Content-Type': 'application/x-www-form-urlencoded'}
      );
      return jsonDecode(response.body);
    } catch (err) {
      print('err charging user: ${err.toString()}');
    }
    return null;
  }
}
