Flutter电话功能扩展插件phone_pe_pg的使用
Flutter电话功能扩展插件phone_pe_pg的使用
简介
phone_pe_pg
是一个用于在Flutter应用中集成PhonePe支付网关的插件。当前基于PhonePe SDK Less集成,仅支持Android和iOS平台。
准备工作
- UAT测试:需要安装名为’PhonePe Simulator’的应用,并请求PhonePe团队提供。
- 生产环境:需编写API来调用PhonePe支付API,并分享服务器IP给PhonePe团队以进行白名单设置。
开始使用
1. 添加依赖
在pubspec.yaml
文件中添加依赖:
dependencies:
phone_pe_pg: ^0.0.1
2. 导入包
在Dart文件中导入插件:
import 'package:phone_pe_pg/phone_pe_pg.dart';
3. 初始化PhonePePG
PhonePePg phonePePg = PhonePePg(
isUAT: true,
saltKey: Secrets.saltKey,
saltIndex: Secrets.saltIndex,
prodUrl: yourapi/url
);
参数说明:
isUAT
: 布尔值,决定使用UAT或生产环境。saltKey
: PhonePe提供的盐密钥。saltIndex
: PhonePe提供的盐索引。prodUrl
: 生产环境下的后端API URL。
支付请求
创建PaymentRequest
对象并初始化:
PaymentRequest paymentRequest = PaymentRequest(
amount: 100, // 金额(单位为INR)
callbackUrl: 'https://www.xyx.com',
deviceContext: DeviceContext.getDefaultDeviceContext(merchantCallBackScheme: merchantCallBackScheme),
merchantId: 'MerchantID',
merchantTransactionId: 'Random Transaction Id',
merchantUserId: 'Random User Id',
mobileNumber: 'Mobile Number',
paymentInstrument: UpiIntentPaymentInstrument(targetApp: Platform.isAndroid ? selectedUPIApp.packageName! : selectedUPIApp.iOSAppName!)
);
UPI Intent支付
获取设备上安装的UPI应用列表:
List<UpiAppInfo> upiApps = await PhonePePg.getUpiApps();
启动UPI交易:
final result = await phonePePg.startUpiTransaction(paymentRequest: paymentRequest);
检查交易状态:
if (result.status == UpiPaymentStatus.success) {
ScaffoldMessenger.of(context).showSnackBar(const SnackBar(content: Text("Transaction Successful")));
} else if (result.status == UpiPaymentStatus.pending) {
ScaffoldMessenger.of(context).showSnackBar(const SnackBar(content: Text("Transaction Pending")));
} else {
ScaffoldMessenger.of(context).showSnackBar(const SnackBar(content: Text("Transaction Failed")));
}
Pay Page支付
启动Pay Page交易:
Navigator.push(context, MaterialPageRoute(builder: (context) => phonePePg.startPayPageTransaction(
paymentRequest: paypageRequestModel(),
onPaymentComplete: (paymentStatusResponse, error) {
if (paymentStatusResponse != null && paymentStatusResponse.code == PaymentStatus.success) {
ScaffoldMessenger.of(context).showSnackBar(const SnackBar(content: Text("Transaction Successful")));
} else {
ScaffoldMessenger.of(context).showSnackBar(const SnackBar(content: Text("Transaction Failed")));
}
},
appBar: YourCustomAppBar() // Optional
)));
检查交易状态
final result = await phonePePg.checkStatus(
merchantId: 'MerchantID',
merchantTransactionId: 'Random Transaction Id',
);

当然,关于Flutter中的phone_pe_pg
插件(这个插件名称可能是一个假设或特定项目的插件,因为常见的Flutter电话功能插件一般是url_launcher
用于拨打电话等),我会提供一个假设性的使用案例代码。由于phone_pe_pg
不是官方或广泛认知的插件,以下代码将基于一个假想的插件功能,即拨打电话和获取设备电话信息。
首先,确保你已经在pubspec.yaml
文件中添加了该插件的依赖(假设插件名称是phone_pe_pg
):
dependencies:
flutter:
sdk: flutter
phone_pe_pg: ^x.y.z # 替换为实际的版本号
然后,运行flutter pub get
来安装插件。
接下来,在你的Dart代码中,你可以这样使用phone_pe_pg
插件:
import 'package:flutter/material.dart';
import 'package:phone_pe_pg/phone_pe_pg.dart'; // 导入插件
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Phone PE PG Plugin Demo'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
ElevatedButton(
onPressed: _makePhoneCall,
child: Text('Make Phone Call'),
),
SizedBox(height: 20),
ElevatedButton(
onPressed: _getDeviceInfo,
child: Text('Get Device Phone Info'),
),
],
),
),
),
);
}
Future<void> _makePhoneCall() async {
try {
// 假设插件提供了一个拨打电话的方法
await PhonePePg.makeCall("tel:+1234567890");
ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text('Call initiated')));
} catch (e) {
ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text('Failed to initiate call: $e')));
}
}
Future<void> _getDeviceInfo() async {
try {
// 假设插件提供了一个获取设备电话信息的方法
PhoneInfo phoneInfo = await PhonePePg.getPhoneInfo();
String infoMessage = 'Phone Number: ${phoneInfo.phoneNumber}\n'
'IMEI: ${phoneInfo.imei}\n'
'Sim Serial Number: ${phoneInfo.simSerialNumber}';
showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
title: Text('Device Phone Info'),
content: Text(infoMessage),
actions: <Widget>[
ElevatedButton(
onPressed: () => Navigator.of(context).pop(),
child: Text('OK'),
),
],
);
},
);
} catch (e) {
ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text('Failed to get phone info: $e')));
}
}
}
// 假设的PhoneInfo类,用于存储设备信息
class PhoneInfo {
final String phoneNumber;
final String imei;
final String simSerialNumber;
PhoneInfo({required this.phoneNumber, required this.imei, required this.simSerialNumber});
}
// 假设的PhonePePg类,用于提供插件功能
class PhonePePg {
static Future<void> makeCall(String phoneNumber) async {
// 插件内部实现拨打电话的逻辑
// 这里只是模拟调用
throw UnsupportedError('makeCall method is not implemented in this demo.');
}
static Future<PhoneInfo> getPhoneInfo() async {
// 插件内部实现获取设备信息的逻辑
// 这里只是模拟返回一些数据
return PhoneInfo(
phoneNumber: '123-456-7890', // 模拟电话号码
imei: '123456789012345', // 模拟IMEI号
simSerialNumber: '987654321098765', // 模拟SIM卡序列号
);
}
}
请注意,上面的代码中的PhonePePg
类和PhoneInfo
类是基于假设的,因为实际的phone_pe_pg
插件可能有不同的API和实现。你应该参考插件的官方文档来了解其真实的方法和属性。
此外,由于获取设备的电话号码、IMEI等信息可能涉及用户隐私,因此在实际应用中需要确保遵守相关的隐私政策和法律法规。在iOS和Android上,获取这些信息通常需要用户的明确授权。
