如何在Flutter中使用Razorpay Orders API？

Question

我正在我的flutter应用程序中实现一个支付网关。所以Razorpay推荐我使用Orders API。但是我没有得到任何实现Orders API的方法。

我参考了下面的文档。它包含java、PHP等的示例，但没有找到Flutter / Dart的示例。

提前谢谢。

Answer 1

值得庆幸的是，Razorpay有Flutter软件包，你可以使用它。下面的代码片段可能会有所帮助：

import 'package:razorpay_flutter/razorpay_flutter.dart';

_razorpay = Razorpay();

var options = {
      'key': '<YOUR_KEY_ID>',
      'amount': 100, //in the smallest currency sub-unit.
      'name': 'Acme Corp.',
      'order_id': 'order_EMBFqjDHEEn80l', // Generate order_id using Orders API
      'description': 'Fine T-Shirt',
      'prefill': {
        'contact': '9123456789',
        'email': 'gaurav.kumar@example.com'
      }
    };

_razorpay.open(options);

  Future<void> generate_ODID() async {
      var orderOptions = {
        'amount': 50000,  // amount in the smallest currency unit
        'currency': "INR",
        'receipt': "order_rcptid_11"
      };
      final client = HttpClient();
      final request =
          await client.postUrl(Uri.parse('https://api.razorpay.com/v1/orders'));
      request.headers.set(
          HttpHeaders.contentTypeHeader, "application/json; charset=UTF-8");
      String basicAuth = 'Basic ' +
          base64Encode(utf8.encode(
              '${'YourKEY'}:${'YourSECRET'}'));
      request.headers.set(HttpHeaders.authorizationHeader, basicAuth);
      request.add(utf8.encode(json.encode(orderOptions)));
      final response = await request.close();
      response.transform(utf8.decoder).listen((contents) {
        print('ORDERID'+contents);
        String orderId = contents.split(',')[0].split(":")[1];
        orderId = orderId.substring(1, orderId.length - 1);
        Fluttertoast.showToast(
            msg: "ORDERID: " +orderId,
            toastLength: Toast.LENGTH_SHORT);
        Map<String, dynamic> checkoutOptions = {
          'key': 'YourKEY',
          'amount': 11100,
          'name': 'Demo',
          'description': 'Fssai Registrtion Charge',
          'prefill': {'contact': '8910407549', 'email': 'xx.xx@gmail.com'},
          'external': {
            'wallets': ['paytm']
          }
        };
        try {
          _razorpay.open(checkoutOptions);
        } catch (e) {
          print(e.toString());
        }
    });
    }

我正在使用这个相同的代码片段，但当我试图用谷歌支付付款时，它将失败与“您的钱没有借记，您的服务器忙”错误，但当我试图手动提供UPI Id然后交易顺利进行，否则交易不使用UPI完成。有什么办法可以解决这个问题吗？

final client = HttpClient();
  final request =
      await client.postUrl(Uri.parse('https://api.razorpay.com/v1/orders'));
  request.headers.set(
      HttpHeaders.contentTypeHeader, "application/json; charset=UTF-8");
  String basicAuth = 'Basic ' +
      base64Encode(utf8.encode(
          '${dotenv.env['RAZORPAY_KEY']!}:${dotenv.env['RAZORPAY_SECRET']!}'));
  request.headers.set(HttpHeaders.authorizationHeader, basicAuth);
  request.add(utf8.encode(json.encode(orderOptions)));
  final response = await request.close();
  response.transform(utf8.decoder).listen((contents) {
    String orderId = contents.split(',')[0].split(":")[1];
    orderId = orderId.substring(1, orderId.length - 1);
    Map<String, dynamic> checkoutOptions = {
      'key': dotenv.env['RAZORPAY_KEY']!,
      'amount': total * 100,
      "currency": "INR",
      'name': 'E Drives',
      'description': 'E Bike',
      'order_id': orderId, // Generate order_id using Orders API
      'timeout': 300,
    };
    try {
      _razorpay.open(checkoutOptions);
    } catch (e) {
      log.e(e.toString());
    }

您可以使用HttpClient并向Razorpay Orders API发送请求。希望这能回答你的问题。
