Flutter支付集成插件payaza的使用

Flutter支付集成插件payaza的使用

Payaza的SDK使得在应用中开始接受客户的支付变得非常简单。通过简单的步骤集成支付SDK,您可以轻松地开始接受付款。

开始使用

要在您的应用中开始收集支付,请在pubspec.yaml文件中添加payaza依赖项:

dependencies:
  payaza: ^0.0.1

使用方法

在使用之前,请初始化SDK:

// 初始化SDK
Payaza.init('<public key>');

// 运行应用
runApp(const MyApp());

以下是一个完整的示例,展示了如何集成Payaza支付功能:

import 'package:example/my_custom_form.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:payaza/payaza.dart';

void main() {
  // 初始化Payaza SDK
  Payaza.init('PZ78-PKLIVE-FA9BB0D3-592F-4F8D-BA29-85F8B267F4A8');
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Payaza Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Payaza Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  Widget adaptiveAction({
    required BuildContext context,
    required VoidCallback onPressed,
    required Widget child,
  }) {
    final ThemeData theme = Theme.of(context);
    switch (theme.platform) {
      case TargetPlatform.android:
      case TargetPlatform.fuchsia:
      case TargetPlatform.linux:
      case TargetPlatform.windows:
        return TextButton(onPressed: onPressed, child: child);
      case TargetPlatform.iOS:
      case TargetPlatform.macOS:
        return CupertinoDialogAction(onPressed: onPressed, child: child);
    }
  }

  Future<void> showAlert({
    required String title,
    required String message,
  }) async {
    return await showAdaptiveDialog(
      context: context,
      builder: (BuildContext context) => AlertDialog.adaptive(
        title: Text(title),
        content: Text(message),
        actions: [
          adaptiveAction(
            context: context,
            onPressed: () => Navigator.pop(context, 'OK'),
            child: const Text(
              'OK',
              style: TextStyle(color: Color(0xFF2357d1)),
            ),
          ),
        ],
      ),
    );
  }

  void handleSuccess(PayazaSuccessResponse response) async {
    await showAlert(
        message: response.data.payazaReference ?? '',
        title: 'Payment Successful');
  }

  void handleError(PayazaErrorResponse response) async {
    await showAlert(message: response.data.message, title: 'Error');
  }

  void handleClose() {
    print('Payaza widget was closed');
  }

  void onSubmit(FormData data) {
    Payaza.init(data.merchantKey);
    Payaza.createTransaction(
      context,
      config: PayazaConfig(
        amount: data.amount,
        connectionMode: PayazaConnectionMode.LIVE_CONNECTION_MODE,
        email: data.email,
        firstName: data.firstName,
        lastName: data.lastName,
        phoneNumber: data.phoneNumber,
        transactionReference: 'PY_${DateTime.now().toIso8601String()}',
        currencyCode: data.currency,
      ),
      onSuccess: handleSuccess,
      onError: handleError,
      onClose: handleClose,
    );
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Padding(
        padding: const EdgeInsets.all(8.0),
        child: MyCustomForm(onSubmit: onSubmit),
      ),
    );
  }
}

在Flutter项目中集成Payaza支付插件,通常需要按照插件提供的官方文档进行配置和调用。由于具体的实现可能会因插件版本或Payaza的API更新而有所变化,以下是一个基本的示例代码框架,展示如何在Flutter中集成和使用Payaza支付插件。

首先,确保你的Flutter项目已经创建,并且pubspec.yaml文件中已经添加了Payaza支付插件的依赖(假设该插件在pub.dev上可用,实际使用时请替换为真实插件名和版本)。

1. 添加依赖

pubspec.yaml文件中添加Payaza插件依赖:

dependencies:
  flutter:
    sdk: flutter
  payaza_flutter_plugin: ^x.y.z  # 替换为实际版本号

然后运行flutter pub get来安装依赖。

2. 配置Payaza

在Flutter项目的android/app/src/main/AndroidManifest.xmlios/Runner/Info.plist文件中,根据Payaza的要求添加必要的配置信息,如API密钥、支付回调URL等。

3. 初始化Payaza插件

在你的Flutter应用中,初始化Payaza插件并设置必要的参数。以下是一个简单的示例代码:

import 'package:flutter/material.dart';
import 'package:payaza_flutter_plugin/payaza_flutter_plugin.dart';  // 假设插件名为payaza_flutter_plugin

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Payaza Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final PayazaFlutterPlugin payaza = PayazaFlutterPlugin();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Payaza Integration'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            _initiatePayment();
          },
          child: Text('Initiate Payment'),
        ),
      ),
    );
  }

  void _initiatePayment() async {
    try {
      // 替换为实际的支付参数
      String paymentId = "your_payment_id";
      String amount = "10.00";
      String currency = "USD";
      String description = "Test Payment";

      // 调用Payaza插件的支付方法
      bool result = await payaza.initiatePayment(
        paymentId: paymentId,
        amount: amount,
        currency: currency,
        description: description,
      );

      if (result) {
        showDialog(
          context: context,
          builder: (BuildContext context) {
            return AlertDialog(
              title: Text("Payment Status"),
              content: Text("Payment successful!"),
              actions: <Widget>[
                TextButton(
                  onPressed: () {
                    Navigator.of(context).pop();
                  },
                  child: Text("OK"),
                ),
              ],
            );
          },
        );
      } else {
        showDialog(
          context: context,
          builder: (BuildContext context) {
            return AlertDialog(
              title: Text("Payment Status"),
              content: Text("Payment failed!"),
              actions: <Widget>[
                TextButton(
                  onPressed: () {
                    Navigator.of(context).pop();
                  },
                  child: Text("OK"),
                ),
              ],
            );
          },
        );
      }
    } catch (e) {
      print("Error initiating payment: $e");
      showDialog(
        context: context,
        builder: (BuildContext context) {
          return AlertDialog(
            title: Text("Error"),
            content: Text("An error occurred while initiating payment."),
            actions: <Widget>[
              TextButton(
                onPressed: () {
                  Navigator.of(context).pop();
                },
                child: Text("OK"),
              ),
            ],
          );
        },
      );
    }
  }
}

注意事项

  1. 插件版本:确保你使用的是最新版本的Payaza Flutter插件,因为旧版本可能不支持最新的Payaza API或包含已知的安全漏洞。

  2. API密钥:在正式环境中,请确保你的API密钥和其他敏感信息被安全地存储和传输。

  3. 支付回调:Payaza支付成功后,通常会有一个支付回调URL。你需要在服务器端配置这个回调URL,以处理支付结果并更新你的订单状态。

  4. 错误处理:在实际应用中,添加更详细的错误处理和用户反馈机制,以提高用户体验。

  5. 文档:始终参考Payaza的官方文档和Flutter插件的README文件,以获取最新的集成指南和API信息。

由于我无法直接访问实际的Payaza Flutter插件代码和文档,以上示例代码是基于假设的插件名称和API方法编写的。在实际使用时,请根据你使用的插件版本和Payaza的API要求进行调整。
