Flutter支付集成插件stripe_intent_data的使用

stripe_intent_data

stripe_intent_data 是一个新的 Flutter 包，旨在减少编写与 Stripe 相关代码的工作量，例如创建客户 ID、获取支付意图数据和获取收费详情。

开始使用

创建支付意图

String stripeSecretKey =
    'sk_test_51I';

var data = await StripeIntentData(
  currency: 'EUR',
  stripeSecretKey: stripeSecretKey,
).getStripeIntent('name', 'email ID', 'amount', 'customer ID if available otherwise null');

获取支付详情

String stripeSecretKey =
    'sk_test_51I';

var data = await StripeIntentData(
  currency: 'EUR',
  stripeSecretKey: stripeSecretKey,
).getPaymentDetails(paymentIntentID);

使用案例示例

完整示例代码

以下是一个完整的示例代码，展示了如何在 Flutter 应用中使用 stripe_intent_data 插件进行支付集成。

import 'dart:developer';

import 'package:example/stripe_key.dart';
import 'package:flutter/material.dart';
import 'package:flutter_stripe/flutter_stripe.dart';
import 'package:stripe_intent_data/response/intent_data.dart';
import 'package:stripe_intent_data/stripe_intent_data.dart';
import 'package:url_launcher/url_launcher.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  Stripe.publishableKey = publishableKeyTest; // 你的发布密钥
  Stripe.merchantIdentifier = '';
  await Stripe.instance.applySettings();
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

  IntentData? paymentIntentData;
  String? customerID;
  String? receiptURL;

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(

        child: MaterialButton(
          onPressed: () async {
            checkOut();

            "Pay Now",

              fontSize: 17,
            ),
          ),
        ),
      ),
    );
  }

  Future<void> checkOut() async {
    /// 存储客户ID到数据库
    /// 初始时为null，Stripe会创建客户ID，并通过intentData对象获取它
    /// 当你获取到它后，保存到数据库
    /// 需要时调用

    paymentIntentData = await StripeIntentData(
      stripeSecretKey: stripeSecretKey,
      currency: 'EUR',
    ).getStripeIntent('User One', 'userone@user.com', '2000', customerID);

    await Stripe.instance.initPaymentSheet(
      paymentSheetParameters: SetupPaymentSheetParameters(

        paymentIntentClientSecret: paymentIntentData!.paymentIntentClientSecret,
        customerEphemeralKeySecret: paymentIntentData!.ephemeralKey,
        customerId: paymentIntentData!.customer,
      ),
    );

    await displayPaymentSheet();
    Uri _url = Uri.parse(receiptURL!);
    await launchUrl(_url, mode: LaunchMode.inAppWebView);
  }

  displayPaymentSheet() async {
    try {
      await Stripe.instance.presentPaymentSheet().then((newValue) async {
        /// 获取收费详情
        var data = await StripeIntentData(
          stripeSecretKey: stripeSecretKey,
          currency: 'EUR',
        ).getPaymentDetails(
          paymentIntentData!.paymentIntentId!,
        );
        setState(() {
          receiptURL = data.receiptUrl;
          // 保存客户ID到数据库（在实际应用中）
          customerID = paymentIntentData!.customer;
        });
      });
    } on StripeException catch (e) {
      log(e.error.message.toString());
    } catch (e) {
      log(e.toString());
    }
  }
