需要实现的核心服务

1. 支付服务实现

支付宝支付示例结构

// backend/FateMaster.API/Services/Payment/AlipayService.cs
public class AlipayService : IPaymentService
{
    public async Task<PaymentResult> CreateOrder(decimal amount, string orderId)
    {
        // 调用支付宝SDK创建订单
        // 返回支付链接或二维码
    }

    public async Task<bool> VerifyCallback(Dictionary<string, string> parameters)
    {
        // 验证支付宝回调签名
        // 更新订单状态
    }
}

PayPal支付示例结构

// backend/FateMaster.API/Services/Payment/PayPalService.cs
public class PayPalService : IPaymentService
{
    public async Task<PaymentResult> CreateOrder(decimal amount, string orderId)
    {
        // 调用PayPal API创建订单
    }

    public async Task<bool> CapturePayment(string paymentId)
    {
        // 捕获支付
    }
}

Stripe支付示例结构

// backend/FateMaster.API/Services/Payment/StripeService.cs
public class StripeService : IPaymentService
{
    public async Task<PaymentResult> CreatePaymentIntent(decimal amount, string orderId)
    {
        // 使用Stripe.net SDK
        // 创建PaymentIntent
    }
}

2. AI解读服务实现

// backend/FateMaster.API/Services/AI/AIService.cs
public class AIService
{
    private readonly HttpClient _httpClient;
    private readonly string _apiKey;
    private readonly string _model;

    public async Task<string> InterpretDivination(string type, string traditionalResult)
    {
        // 构建提示词
        var prompt = BuildPrompt(type, traditionalResult);

        // 调用OpenAI API
        var response = await _httpClient.PostAsync("chat/completions", new
        {
            model = _model,
            messages = new[]
            {
                new { role = "system", content = "你是一位专业的命理大师" },
                new { role = "user", content = prompt }
            }
        });

        // 解析返回结果
        return await ParseResponse(response);
    }

    private string BuildPrompt(string type, string traditionalResult)
    {
        switch (type)
        {
            case "bazi":
                return $"请根据以下八字命盘进行详细解读：{traditionalResult}";
            case "tarot":
                return $"请解读以下塔罗牌组合：{traditionalResult}";
            // ... 其他类型
            default:
                return traditionalResult;
        }
    }
}

3. 批八字算法实现

// backend/FateMaster.API/Services/Divination/BaZiService.cs
public class BaZiService
{
    public BaZiResult Calculate(BaZiInput input)
    {
        // 1. 转换公历/农历
        var solarDate = ConvertToSolar(input);

        // 2. 计算四柱
        var fourPillars = CalculateFourPillars(solarDate);

        // 3. 排大运
        var majorCycles = CalculateMajorCycles(fourPillars, input.Gender);

        // 4. 五行分析
        var elements = AnalyzeElements(fourPillars);

        // 5. 十神分析
        var tenGods = AnalyzeTenGods(fourPillars);

        return new BaZiResult
        {
            FourPillars = fourPillars,
            MajorCycles = majorCycles,
            Elements = elements,
            TenGods = tenGods
        };
    }

    private FourPillars CalculateFourPillars(DateTime date)
    {
        // 天干地支计算逻辑
        // 年柱、月柱、日柱、时柱
    }
}

4. 塔罗牌服务实现

// backend/FateMaster.API/Services/Divination/TarotService.cs
public class TarotService
{
    private readonly Dictionary<int, TarotCard> _cards;

    public TarotResult Interpret(List<int> selectedCardIds, string question)
    {
        var cards = selectedCardIds.Select(id => _cards[id]).ToList();

        // 三张牌的位置含义
        var positions = new[]
        {
            "过去/问题根源",
            "现在/当前状况",
            "未来/发展趋势"
        };

        var interpretation = new StringBuilder();
        for (int i = 0; i < cards.Count; i++)
        {
            interpretation.AppendLine($"{positions[i]}: {cards[i].Name}");
            interpretation.AppendLine(cards[i].Meaning);
        }

        return new TarotResult
        {
            Cards = cards,
            Interpretation = interpretation.ToString()
        };
    }
}

前端开发规范

组件命名

• 页面组件：PascalCase (例如：BaZi.vue)
• 布局组件：PascalCase + Layout (例如：MainLayout.vue)
• 通用组件：PascalCase (例如：PaymentModal.vue)

API调用封装

// src/api/divination.ts
import axios from 'axios'

export const divinationApi = {
  getPrices: () => axios.get('/api/divination/prices'),

  submit: (data: SubmitRequest) =>
    axios.post('/api/divination/submit', data),

  getResult: (id: number) =>
    axios.get(`/api/divination/${id}`)
}

状态管理示例

// src/stores/divination.ts
import { defineStore } from 'pinia'

export const useDivinationStore = defineStore('divination', {
  state: () => ({
    history: [] as DivinationRecord[],
    currentResult: null as DivinationRecord | null
  }),

  actions: {
    addToHistory(record: DivinationRecord) {
      this.history.push(record)
      localStorage.setItem('divination_history', JSON.stringify(this.history))
    }
  }
})

测试建议

单元测试

// 测试八字计算
[Fact]
public void Calculate_ValidInput_ReturnsCorrectFourPillars()
{
    var service = new BaZiService();
    var input = new BaZiInput
    {
        BirthDate = new DateTime(1990, 1, 1, 12, 0, 0),
        Gender = "male"
    };

    var result = service.Calculate(input);

    Assert.NotNull(result.FourPillars);
}

集成测试

[Fact]
public async Task Submit_ValidRequest_CreatesRecord()
{
    var response = await _client.PostAsJsonAsync("/api/divination/submit", new
    {
        Type = "bazi",
        InputData = "{}",
        Amount = 99
    });

    Assert.Equal(HttpStatusCode.OK, response.StatusCode);
}

性能优化建议

1. 前端优化

   • 使用路由懒加载
   • 图片使用WebP格式
   • 启用Gzip压缩

2. 后端优化

   • 使用Redis缓存价格配置
   • 数据库查询添加索引
   • 异步处理AI解读

3. 数据库优化

   • 为常用查询字段添加索引
   • 定期清理旧数据
   • 使用只读副本分担查询

安全建议

1. API安全

   • 实现请求频率限制
   • 添加CSRF保护
   • 使用HTTPS

2. 数据安全

   • 敏感数据加密存储
   • 定期备份数据库
   • 实现访问日志

3. 支付安全

   • 验证所有支付回调
   • 金额校验
   • 防止重复支付
