Flutter支付集成插件basispaysdkv2的使用

Baisipay-Flutter-PG-SDKV2-KIT

这是一个用于在Flutter应用中使用BasisPay支付网关插件以接受在线支付的库。

简介

本文件描述了集成BasisPay在线支付网关Flutter SDK套件的步骤。该支付网关通过减少用户操作来执行在线支付交易。它接收支付详情作为输入，并处理支付流程，最终将支付响应返回给用户。用户必须手动将框架导入其项目中才能使用。

要求

• Android最小SDK版本：21

首先从BasisPay获取凭证

插件仅在使用API密钥时才有效。

ANDROID

步骤1:

转到你的应用的android文件夹并进入build.gradle文件

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

开始支付

Future<void> initPlatformState() async {
  Map<String, dynamic> paymentRequestParams = {
    // 必需参数
    "apiKey": "YOUR_PG_API_KEY",
    "secureHash": "xxxx",
    "orderReference": "xxxx",
    "customerName": "xxxx",
    "customerEmail": "xxxx",
    "customerMobile": "xxxxxxxxxx",
    "address": "xxxx",
    "postalCode": "xxxx",
    "city": "xxxx",
    "region": "xxxx",
    "country": "xxx", // ISO 3码，例如：IND
    "returnUrl": "xxxx",
    "isPgMode": false, // 如果PG模式为LIVE，则设为true，否则为false（测试模式）
    // 可选参数
    "deliveryAddress": "xxxx",
    "deliveryCustomerName": "xxxx",
    "deliveryCustomerMobile": "xxxxxxxxxx",
    "deliveryPostalCode": "xxxx",
    "deliveryCity": "xxxx",
    "deliveryRegion": "xxxx",
    "deliveryCountry": "xxx", // ISO 3码，例如：IND
  };

  try {
    var response = Basispaysdkv2.startTransaction(paymentRequestParams);
    response.then((value) {
      print(value);
      var referenceNo = value['referenceNo'];
      var success = value['success'];
    }).catchError((onError) {
      if (onError is PlatformException) {
        setState(() {
          print(onError.message + " \n  " + onError.details.toString());
        });
      } else {
        setState(() {
          print(onError.toString());
        });
      }
    });
  } catch (err) {
    print(err.toString());
  }
}
