我正在尝试在我的应用程序中实现 Stripe，但确实收到此错误。
网络不支持 initPaymentSheet 我不知道如何使其在网络上工作。
WidgetsFlutterBinding.ensureInitialized();
Get.put(MenuController());
Get.put(NavigationController());
await initialization;
Stripe.publishableKey =
'pk_test_5555851KuZKPKYrgcm5L1......';
Stripe.merchantIdentifier = 'merchant.flutter.stripe.test';
Stripe.urlScheme = 'flutterstripe';
await Stripe.instance.applySettings();
runApp((MultiProvider(
providers: [
ChangeNotifierProvider(
create: (context) => ApplicationState(),
builder: (context, _) => MyApp(),
)
],
// child: MyApp(),
)));
}
Future<void> makePayment(String amount, String currency) async {
try {
paymentIntentData = await createPaymentIntent(amount, currency);
await Stripe.instance.initPaymentSheet(
paymentSheetParameters: SetupPaymentSheetParameters(
paymentIntentClientSecret: paymentIntentData!['client_secret'],
applePay: true,
googlePay: true,
merchantCountryCode: 'US',
merchantDisplayName: 'KasaiMart'));
displayPaymentSheet();
} on StripeException catch (e) {
print('Exeption ${e.toString()}');
}
}
displayPaymentSheet() async {
try {
await Stripe.instance.presentPaymentSheet();
paymentIntentData = null;
Get.defaultDialog(
title: 'Select project to contribute to',
middleText: 'Paid Sucessfully');
} catch (e) {
print('Exeption ${e.toString()}');
}
}
createPaymentIntent(String amount, String currency) async {
try {
Map<String, dynamic> body = {
'amount': calculateAmount(amount),
'currency': currency,
'payment_method_types[]': 'card'
};
var response = await http.post(
Uri.parse('https://api.stripe.com/v1/payment_intents'),
body: body,
headers: {
'Authorization':
'pk_test_51K......',
'Content-Type': 'application/x-www-form-urlencoded'
});
return jsonDecode(response.body.toString());
} catch (e) {
print('Exeption ${e.toString()}');
}
}
我在哪种方法中做错了什么？是否可以解决此问题，或者是否来自软件包本身？
Stripe for Web 仍处于高度实验阶段。 来自 Github 上的自述文件：注意，现在它处于高度实验阶段，仅实现了一部分功能。
您还可以在 stripe_web 插件存储库中检查
initPaymentSheetWebUnsupportedError使用 stripe 中的信用卡字段
Stripe.buildWebCard(
controller: controller,
onCardChanged: (details) {
card = details;
setState(() {
allowPayment = details?.complete == true;
});
},
),
这是一个完整的示例：

stripe 会自行从卡输入中获取信用卡信息
initPaymentSheet如果您想通过网络呈现类似于付款表的内容，您可以考虑使用付款元素：https://stripe.com/docs/ payments/ payment-element
