数字化业绩管理系统数据采集模块：自动对接业务系统、多维度数据整合（告别手动录入）实操指南

// 使用HttpClient调用业务系统API示例
public async Task FetchPerformanceDataAsync(string apiUrl)
{
    using (var httpClient = new HttpClient())
    {
        // 设置认证头
        httpClient.DefaultRequestHeaders.Authorization = 
            new AuthenticationHeaderValue("Bearer", "your-access-token");
        
        // 发送GET请求
        var response = await httpClient.GetAsync(apiUrl);
        
        if (response.IsSuccessStatusCode)
        {
            var jsonResponse = await response.Content.ReadAsStringAsync();
            // 反序列化JSON数据
            return JsonSerializer.Deserialize(jsonResponse);
        }
        
        throw new Exception($"API请求失败: {response.StatusCode}");
    }
}

// 使用Entity Framework Core进行数据库操作
public class PerformanceDataService
{
    private readonly BusinessSystemDbContext _context;
    
    public PerformanceDataService(BusinessSystemDbContext context)
    {
        _context = context;
    }
    
    public async Task<>> GetSalesDataAsync(DateTime startDate, DateTime endDate)
    {
        return await _context.SalesRecords
            .Where(s => s.SaleDate >= startDate && s.SaleDate <= endDate)
            .Select(s => new SalesData 
            {
                ProductId = s.ProductId,
                Quantity = s.Quantity,
                Amount = s.Amount,
                Region = s.Region
            })
            .ToListAsync();
    }
}

// 数据清洗与标准化示例
public class DataNormalizationService
{
    public NormalizedData NormalizeSalesData(RawSalesData rawData)
    {
        return new NormalizedData
        {
            // 统一产品编号格式
            ProductCode = StandardizeProductCode(rawData.ProductCode),
            // 统一日期格式
            SaleDate = ParseDate(rawData.SaleDateString),
            // 统一货币单位
            Amount = ConvertToBaseCurrency(rawData.Amount, rawData.Currency),
            // 统一区域编码
            RegionCode = MapRegionCode(rawData.RegionName)
        };
    }
    
    private string StandardizeProductCode(string rawCode)
    {
        // 实现产品编号标准化逻辑
        return rawCode.Trim().ToUpper();
    }
}
