Flutter Stripe 不显示/出示付款单

Question

在我的 flutter 项目中，我尝试使用 flutter_stripe 包集成 Stripe 支付。
我已正确初始化并配置。但是，当尝试出示付款表时，没有任何显示或发生。也没有错误原因。因为它卡在线路上并且之后没有运行代码。我也尝试过插件简单的示例代码，但没有按我想要的方式工作。任何帮助将不胜感激。

main.dart

  Stripe.publishableKey = StripeService.publishableKey;
  Stripe.merchantIdentifier = 'merchant.flutter.stripe.test';
  Stripe.urlScheme = 'flutterstripe';
  await Stripe.instance.applySettings();
  runApp(const MyApp());
}

服务.dart

Future<void> initPaymentSheet() async {
try {
  // 1. create payment intent on the server
  final paymentSheetData = await createPaymentIntent("1200", 'usd');
  print("payment intent created");

  // create some billingdetails
  final billingDetails = BillingDetails(
    email: '[email protected]',
    phone: '[phone]',
    address: Address(
      city: 'Houston',
      country: 'US',
      line1: '1459  Circle Drive',
      line2: '',
      state: 'Texas',
      postalCode: '77063',
    ),
  ); // mocked data for tests

 // 2. initialize the payment sheet
  await Stripe.instance.initPaymentSheet(
      paymentSheetParameters: SetupPaymentSheetParameters(
    applePay: true,
    googlePay: true,
    style: ThemeMode.dark,
    testEnv: true,
    merchantCountryCode: 'US',
    merchantDisplayName: 'Prospects',
    customerId: paymentSheetData!['customer'],
    paymentIntentClientSecret: paymentSheetData['paymentIntent'],
    customerEphemeralKeySecret: paymentSheetData['ephemeralKey'],
  ));
  print("payment sheet created");

  await Stripe.instance.presentPaymentSheet();

  print("after payment sheet presented");
} on Exception catch (e) {
  if (e is StripeException) {
    print("Error from Stripe: ${e.error.localizedMessage}");
  } else {
    print("Unforeseen error: ${e}");
  }
  rethrow;
}

}

输出

I/flutter (14987)：已创建支付意图
I/flutter (14987)：已创建付款表

Answer 1

我检查您的后端响应，您使用的是“ paymentIntent”而不是“ client_secret”，您应该如下初始化您的付款表

await Stripe.instance.initPaymentSheet(
  paymentSheetParameters: SetupPaymentSheetParameters(
    applePay: true,
    googlePay: true,
    style: ThemeMode.dark,
    testEnv: true,
    merchantCountryCode: 'US',
    merchantDisplayName: 'Prospects',
    customerId: paymentSheetData!['customer'],
    paymentIntentClientSecret: paymentSheetData['client_secret'],
    customerEphemeralKeySecret: paymentSheetData['ephemeralKey'],
));

Answer 2

我已经解决了，初始化付款单时参数值不正确

错了

paymentIntentClientSecret: paymentSheetData['paymentIntent'],

正确

paymentIntentClientSecret: paymentIntentData!['client_secret'],

Answer 3

如果您使用的是 stripe connect，请务必输入 Stripe.stripeAccountId 值，否则会出错。

 Stripe.stripeAccountId = paymentDetails.stripe_account_id;

      await Stripe.instance.applySettings();

      if (Stripe.stripeAccountId == '') {
        print(
            'You need to connect your Stripe account via the dashboard.');
        return;
      }
    ```
