痛点与挑战：从普通电商到医疗合规平台

医疗电商平台面临的核心挑战在于如何在提供便捷购物体验的同时，满足《健康保险流通与责任法案》（HIPAA）的严格要求。传统电商系统如eShopOnWeb主要设计用于商品交易，缺乏对电子受保护健康信息（ePHI）的特殊处理机制。医疗电商改造需要解决三大核心问题：数据加密传输、访问权限精细控制、审计日志全程追踪。

合规改造架构设计

系统安全层改造

医疗数据保护的第一道防线是传输加密。原项目中AuthorizationConstants.cs定义了JWT密钥常量，但直接硬编码在代码中存在泄露风险。改造方案采用Azure Key Vault存储敏感密钥，通过Infrastructure/Services/实现密钥动态获取：

// 改造后的密钥获取方式
var key = await _keyVaultService.GetSecretAsync("JWT-SECRET-KEY");
var tokenHandler = new JwtSecurityTokenHandler();
var tokenDescriptor = new SecurityTokenDescriptor
{
    Subject = new ClaimsIdentity(new Claim[]
    {
        new Claim(ClaimTypes.Name, user.UserName),
        new Claim("PatientId", patient.Id.ToString()),
        new Claim("HIPAA-Access", "Limited")
    }),
    Expires = DateTime.UtcNow.AddMinutes(30),
    SigningCredentials = new SigningCredentials(
        new SymmetricSecurityKey(Encoding.ASCII.GetBytes(key)),
        SecurityAlgorithms.HmacSha256Signature)
};

健康检查机制扩展

原项目的HomePageHealthCheck.cs仅验证首页内容，改造后增加HIPAA合规性健康检查端点：

// 新增HIPAA合规检查
public async Task<HealthCheckResult> CheckHealthAsync(HealthCheckContext context, CancellationToken cancellationToken)
{
    // 检查数据库加密状态
    var dbEncryptionStatus = await _dbService.CheckEncryptionStatusAsync();
    // 验证审计日志服务运行状态
    var auditLogStatus = await _auditService.VerifyServiceHealthAsync();
    
    if (dbEncryptionStatus && auditLogStatus)
    {
        return HealthCheckResult.Healthy("HIPAA compliance requirements met");
    }
    return HealthCheckResult.Degraded("Partial HIPAA compliance");
}

在Program.cs中注册新的健康检查端点：

app.MapHealthChecks("/health/hipaa", new HealthCheckOptions 
{ 
    Predicate = check => check.Name == "hipaa-compliance-check",
    ResponseWriter = HIPAAHealthCheckResponseWriter.WriteAsync
});

患者数据保护实现

数据分类与访问控制

医疗数据需按敏感度分级，在ApplicationCore/Entities/下新增Patient实体：

public class Patient : BaseEntity
{
    public string FullName { get; set; }
    public string Email { get; set; }
    // 受保护健康信息(PHI)标记
    [PHISensitiveData]
    public string MedicalRecordNumber { get; set; }
    [PHISensitiveData]
    public DateTime DateOfBirth { get; set; }
    // 非敏感数据
    public string PreferredPharmacy { get; set; }
}

通过Infrastructure/Data/Config/配置实体加密规则：

public class PatientConfiguration : IEntityTypeConfiguration<Patient>
{
    public void Configure(EntityTypeBuilder<Patient> builder)
    {
        // 对PHI字段启用数据库加密
        builder.Property(p => p.MedicalRecordNumber)
               .HasConversion(new EncryptedStringConverter());
        builder.Property(p => p.DateOfBirth)
               .HasConversion(new EncryptedDateTimeConverter());
    }
}

审计日志系统

在Infrastructure/Logging/实现HIPAA合规的审计日志：

public class HipaaAuditLogger : IAppLogger<HipaaAuditLogger>
{
    private readonly ApplicationDbContext _context;
    
    public void LogAccess(string userId, string patientId, string action)
    {
        _context.AuditLogs.Add(new AuditLog
        {
            Timestamp = DateTime.UtcNow,
            UserId = userId,
            PatientId = patientId,
            Action = action,
            IPAddress = _httpContextAccessor.HttpContext.Connection.RemoteIpAddress.ToString(),
            UserAgent = _httpContextAccessor.HttpContext.Request.Headers["User-Agent"].FirstOrDefault()
        });
        _context.SaveChanges();
    }
}

前端权限控制改造

Blazor管理界面调整

BlazorAdmin/Pages/新增患者数据访问页面，实现基于角色的权限控制：

@page "/admin/patients/{patientId}"
@attribute [Authorize(Roles = "MedicalStaff")]
@attribute [HipaaAuthorization(RequiredLevel = AccessLevel.Full)]

<h3>Patient Details</h3>

@if (patient != null)
{
    <div class="patient-info">
        <p>Name: @patient.FullName</p>
        <p>Email: @patient.Email</p>
        @if (HasFullAccess)
        {
            <p>Medical Record: @patient.MedicalRecordNumber</p>
            <p>DOB: @patient.DateOfBirth.ToShortDateString()</p>
        }
        else
        {
            <p class="phi-restricted">Medical information available to authorized staff only</p>
        }
    </div>
}

@code {
    [Parameter]
    public string PatientId { get; set; }
    
    [CascadingParameter]
    private Task<AuthenticationState> AuthStateTask { get; set; }
    
    private Patient patient;
    private bool HasFullAccess { get; set; }
    
    protected override async Task OnInitializedAsync()
    {
        var authState = await AuthStateTask;
        var user = authState.User;
        HasFullAccess = user.HasClaim(c => c.Type == "HIPAA-Access" && c.Value == "Full");
        
        patient = await _patientService.GetPatientAsync(PatientId, HasFullAccess);
        _auditLogger.LogAccess(user.Identity.Name, PatientId, "ViewPatientDetails");
    }
}

API端点保护

PublicApi/CatalogItemEndpoints/中医疗产品API添加HIPAA合规验证：

[HttpGet("medical/products/{productId}")]
[Authorize]
public async Task<ActionResult<CatalogItemDto>> GetMedicalProduct(int productId)
{
    var userId = User.FindFirstValue(ClaimTypes.NameIdentifier);
    var hasAccess = await _authorizationService.CheckHipaaAccessAsync(userId, productId);
    
    if (!hasAccess)
    {
        _auditLogger.LogAccessDenial(userId, $"Medical product {productId}");
        return Forbid();
    }
    
    var product = await _catalogService.GetByIdAsync(productId);
    return _mapper.Map<CatalogItemDto>(product);
}

部署与合规验证

Docker容器安全配置

修改docker-compose.yml添加安全配置：

services:
  publicapi:
    build: ./src/PublicApi
    environment:
      - ASPNETCORE_ENVIRONMENT=Production
      - HIPAA_COMPLIANCE=true
      - DB_ENCRYPTION=Enabled
    volumes:
      - ./logs:/app/logs
    ports:
      - "5000:80"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:80/health/hipaa"]
      interval: 30s
      timeout: 10s
      retries: 3
