```
|
||||
|
||||
### 核心组件
|
||||
|
||||
#### 1. 订单管理器 (OrderFacade)
|
||||
```dart
|
||||
/// 订单服务接口
|
||||
abstract class IOrderFacade {
|
||||
/// 创建订单
|
||||
Future<Either<OrderError, OrderDetail>> createOrder({
|
||||
required OrderCreateParams params,
|
||||
});
|
||||
|
||||
/// 批量获取订单
|
||||
Future<Either<OrderError, OrderList>> fetchOrders({
|
||||
required int pageIndex,
|
||||
required OrderQueryType orderQueryType,
|
||||
int pageSize = 10,
|
||||
OrderRefundQueryType? orderRefundQueryType,
|
||||
});
|
||||
|
||||
/// 取消订单
|
||||
Future<Either<OrderError, Unit>> cancelOrder(String orderId);
|
||||
|
||||
/// 删除订单
|
||||
Future<Either<OrderError, Unit>> delOrder(String orderId);
|
||||
|
||||
/// 获取订单详情
|
||||
Future<Either<OrderError, OrderDetail>> fetchOrderDetail(
|
||||
String orderId, {
|
||||
bool realTimePull = false,
|
||||
});
|
||||
|
||||
/// 获取退款详情
|
||||
Future<Either<OrderError, RefundDetail>> fetchRefundDetail(String orderId);
|
||||
|
||||
/// 获取待支付的总数
|
||||
Future<Either<OrderError, OrderNum>> fetchAllUnpaidNum();
|
||||
|
||||
/// 获取订单状态
|
||||
Future<Either<OrderError, OrderStatus>> fetchOrderStatus(String orderId);
|
||||
}
|
||||
|
||||
class OrderFacade implements IOrderFacade {
|
||||
final OrderRemoteApi? remoteApi;
|
||||
final String? environment;
|
||||
|
||||
OrderFacade(this.remoteApi, this.environment) {
|
||||
remoteApi ??= OrderRemoteApi(Impl());
|
||||
environment ??= defaultOption.environment;
|
||||
OrderModuleConfig.setUp(environment ?? '');
|
||||
}
|
||||
|
||||
@override
|
||||
Future<Either<OrderError, OrderDetail>> createOrder({
|
||||
required OrderCreateParams params,
|
||||
}) async {
|
||||
try {
|
||||
final orderDetail = await remoteApi!.createOrder(params: params);
|
||||
return right(orderDetail);
|
||||
} catch (e) {
|
||||
return left(OrderError.createOrderError(obj: 'create order failed, $e'));
|
||||
}
|
||||
}
|
||||
|
||||
// 其他方法实现...
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. 发票门面 (InvoiceFacade)
|
||||
```dart
|
||||
/// 发票服务接口
|
||||
abstract class IInvoiceFacade {
|
||||
/// 获取发票抬头详情
|
||||
Future<Either<OrderError, InvoiceTitleDetailsDo>> getInvoiceTitleDetails(
|
||||
String titleId,
|
||||
);
|
||||
|
||||
/// 新增/修改发票抬头
|
||||
Future<Either<OrderError, String>> submitInvoiceTitleDetails(
|
||||
InvoiceTitleDetailsDo invoiceTitleDetails,
|
||||
);
|
||||
|
||||
/// 删除发票抬头
|
||||
Future<Either<OrderError, Unit>> delInvoiceTitleDetails(String titleId);
|
||||
|
||||
/// 获取发票抬头列表
|
||||
Future<Either<OrderError, List<InvoiceTitleDetailsDo>>>
|
||||
getInvoiceTitleDetailsList();
|
||||
|
||||
/// 获取发票详情
|
||||
Future<Either<OrderError, InvoiceDetailsDo>> getInvoiceDetails(
|
||||
String invoiceId,
|
||||
);
|
||||
|
||||
/// 获取发票历史列表
|
||||
Future<Either<OrderError, List<InvoiceDetailsDo>>> getInvoiceList({
|
||||
required int pageIndex,
|
||||
required int pageSize,
|
||||
});
|
||||
|
||||
/// 申请开具发票
|
||||
Future<Either<OrderError, Unit>> submitInvoice(InvoiceOptionsDo invoiceOptions);
|
||||
|
||||
/// 获取可开发票的订单列表
|
||||
Future<Either<OrderError, List<NoOpenInvoiceOrderDo>>> getNoOpenInvoiceOrderList({
|
||||
required int pageIndex,
|
||||
required int pageSize,
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
#### 3. 订单状态和类型枚举
|
||||
```dart
|
||||
/// 订单状态枚举
|
||||
enum OrderStatus {
|
||||
unpaid, // 未付款
|
||||
paid, // 已付款
|
||||
processing, // 处理中
|
||||
completed, // 已完成
|
||||
cancelled, // 已取消
|
||||
refunding, // 退款中
|
||||
refunded // 已退款
|
||||
}
|
||||
|
||||
/// 订单查询类型
|
||||
enum OrderQueryType {
|
||||
all, // 全部
|
||||
unpaid, // 待付款
|
||||
paid, // 已付款
|
||||
completed, // 已完成
|
||||
cancelled // 已取消
|
||||
}
|
||||
|
||||
/// 订单退款查询类型
|
||||
enum OrderRefundQueryType {
|
||||
refunding, // 退款中
|
||||
refunded, // 已退款
|
||||
refundFailed // 退款失败
|
||||
}

}
|
||||
```
|
||||
|
||||
## 配置管理
|
||||
|
||||
### 环境配置
|
||||
```dart
|
||||
class OrderConfig {
|
||||
static const String baseUrl = String.fromEnvironment('ORDER_API_BASE_URL');
|
||||
static const String apiKey = String.fromEnvironment('ORDER_API_KEY');
|
||||
static const int timeoutSeconds = 30;
|
||||
static const int maxRetries = 3;
|
||||
}
|
||||
```
|
||||
|
||||
### 支付配置
|
||||
```dart
|
||||
class PaymentConfig {
|
||||
static const Map<PaymentMethod, PaymentProviderConfig> providers = {
|
||||
PaymentMethod.creditCard: PaymentProviderConfig(
|
||||
provider: 'stripe',
|
||||
publicKey: 'pk_live_...',
|
||||
),
|
||||
PaymentMethod.digitalWallet: PaymentProviderConfig(
|
||||
provider: 'alipay',
|
||||
appId: 'app_...',
|
||||
),
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
## 错误处理
|
||||
|
||||
### 订单错误类型
|
||||
```dart
|
||||
enum OrderErrorType {
|
||||
invalidRequest, // 无效请求
|
||||
orderNotFound, // 订单未找到
|
||||
paymentFailed, // 支付失败
|
||||
insufficientStock, // 库存不足
|
||||
orderExpired, // 订单过期
|
||||
unauthorized, // 未授权
|
||||
networkError, // 网络错误
|
||||
serverError // 服务器错误
|
||||
}
|
||||
|
||||
class OrderException implements Exception {
|
||||
final OrderErrorType type;
|
||||
final String message;
|
||||
final Map<String, dynamic>? details;
|
||||
|
||||
const OrderException(this.type, this.message, [this.details]);
|
||||
}
|
||||
```
|
||||
|
||||
## 使用示例
|
||||
|
||||
### 创建订单
|
||||
```dart
|
||||
final orderFacade = buildOrderFacadeImpl();
|
||||
|
||||
try {
|
||||
final orderCreateParams = OrderCreateParams(
|
||||
products: [
|
||||
OrderProduct(
|
||||
productId: 'charging_session',
|
||||
quantity: 1,
|
||||
price: 25.0,
|
||||
),
|
||||
],
|
||||
deliveryAddress: '北京市朝阳区...',
|
||||
paymentMethod: 'alipay',
|
||||
);
|
||||
|
||||
final result = await orderFacade.createOrder(params: orderCreateParams);
|
||||
|
||||
result.fold(
|
||||
(error) => print('订单创建失败: ${error.message}'),
|
||||
(orderDetail) => print('订单创建成功: ${orderDetail.id}'),
|
||||
);
|
||||
} catch (e) {
|
||||
print('订单创建异常: $e');
|
||||
}
|
||||
```
|
||||
|
||||
### 查询订单列表
|
||||
```dart
|
||||
final orderFacade = buildOrderFacadeImpl();
|
||||
|
||||
try {
|
||||
final result = await orderFacade.fetchOrders(
|
||||
pageIndex: 1,
|
||||
orderQueryType: OrderQueryType.all,
|
||||
pageSize: 20,
|
||||
);
|
||||
|
||||
result.fold(
|
||||
(error) => print('查询订单失败: ${error.message}'),
|
||||
(orderList) {
|
||||
print('查询订单成功,共 ${orderList.orders.length} 条记录');
|
||||
for (final order in orderList.orders) {
|
||||
print('订单: ${order.id} - ${order.title} - ${order.status}');
|
||||
}
|
||||
},
|
||||
);
|
||||
} catch (e) {
|
||||
print('查询订单异常: $e');
|
||||
}
|
||||
```
|
||||
|
||||
### 获取订单详情
|
||||
```dart
|
||||
final orderFacade = buildOrderFacadeImpl();
|
||||
|
||||
try {
|
||||
final result = await orderFacade.fetchOrderDetail('order_123');
|
||||
|
||||
result.fold(
|
||||
(error) => print('获取订单详情失败: ${error.message}'),
|
||||
(orderDetail) {
|
||||
print('订单详情获取成功:');
|
||||
print('订单ID: ${orderDetail.id}');
|
||||
print('订单状态: ${orderDetail.status}');
|
||||
print('订单金额: ${orderDetail.orderPrice}');
|
||||
print('产品列表: ${orderDetail.products.map((p) => p.productName).join(', ')}');
|
||||
},
|
||||
);
|
||||
} catch (e) {
|
||||
print('获取订单详情异常: $e');
|
||||
}
|
||||
```
|
||||
|
||||
## 测试策略
|
||||
|
||||
### 单元测试
|
||||
```dart
|
||||
group('OrderManager Tests', () {
|
||||
test('should create order successfully', () async {
|
||||
// Given
|
||||
final request = CreateOrderRequest(/* ... */);
|
||||
|
||||
// When
|
||||
final result = await orderManager.createOrder(request);
|
||||
|
||||
// Then
|
||||
expect(result.isSuccess, true);
|
||||
expect(result.data.status, OrderStatus.created);
|
||||
});
|
||||
|
||||
test('should handle payment failure', () async {
|
||||
// Given
|
||||
final request = PaymentRequest(/* invalid data */);
|
||||
|
||||
// When & Then
|
||||
expect(
|
||||
() => paymentProcessor.initiatePayment(request),
|
||||
throwsA(isA<OrderException>()),
|
||||
);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### 集成测试
|
||||
```dart
|
||||
group('Order Integration Tests', () {
|
||||
testWidgets('complete order flow', (tester) async {
|
||||
// 1. 创建订单
|
||||
final order = await createTestOrder();
|
||||
|
||||
// 2. 处理支付
|
||||
final payment = await processTestPayment(order.id);
|
||||
|
||||
// 3. 验证订单状态
|
||||
final updatedOrder = await getOrder(order.id);
|
||||
expect(updatedOrder.status, OrderStatus.completed);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
