使用.NET 8+ 与飞书API构建组织架构同步服务

廖雯华 · 2025-11-22 11:30:06

一、.NET生态下飞书API集成挑战

.NET企业应用场景

在现代企业数字化转型中，典型的.NET技术栈（如ASP.NET Core MVC/Web API, Entity Framework Core, SQL Server）构建的内部管理系统扮演着核心角色。这些系统承载着企业的关键业务流程，从人力资源管理到权限控制，从财务审批到业务数据分析。
然而，一个普遍存在的痛点是：员工信息在飞书和自建.NET系统间存在严重的数据不一致问题。当新员工入职时，HR在飞书中录入信息，但各个.NET系统仍需手动重复录入；当员工离职或转岗时，权限更新往往滞后，存在安全隐患；部门架构调整时，各系统的数据更新更是不同步，导致报表统计不准确。
同步的核心价值

统一身份认证： 通过建立可靠的组织架构同步机制，为后续实现飞书扫码登录（OAuth 2.0）打下坚实基础。当用户数据在飞书和本地系统保持一致时，才能基于飞书身份实现无缝的单点登录体验。
自动化运维： 利用.NET后台服务（如BackgroundService）实现全自动化的同步流程，替代人工操作，降低运维成本，提高数据准确性。
数据一致性： 确保企业内部所有.NET应用的组织数据与飞书源保持实时一致，为决策提供准确的数据支撑。
二、.NET技术选型

飞书开放平台配置

首先需要在飞书开放平台创建"企业自建应用"：

登录飞书开放平台
创建企业自建应用，获取 AppId 和 AppSecret
申请必要的权限：
- contact:contact:readonly (核心权限，用于读取联系人信息)
- contact:user.employee_id:readonly (用于获取员工ID)
- contact:department:readonly (用于读取部门信息)

.NET项目设置与技术栈

.NET版本： 推荐 .NET 8 (LTS长期支持版本)，充分利用最新的性能优化和语言特性。
Mud.Feishu飞书服务SDK： 这是本次实践的核心组件。Mud.Feishu是一个现代化的.NET库，专门用于简化与飞书API的集成。相比原生SDK，它具有以下优势：
对比维度原生SDK调用Mud.Feishu组件开发效率需要手动构造HTTP请求、处理响应只需调用简洁的接口方法，一行代码完成操作类型安全手动处理JSON序列化，容易出现类型错误提供完整的强类型支持，编译时发现错误令牌管理需要手动获取、刷新和管理访问令牌自动处理令牌获取和刷新机制异常处理需要手动处理各种网络异常和业务异常提供统一的异常处理机制安装Mud.Feishu：

dotnet add package Mud.Feishu --version 1.0.0

复制代码

技术栈完整配置：

// appsettings.json
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft.AspNetCore": "Warning"
}
},
"Feishu": {
"AppId": "your_app_id",
"AppSecret": "your_app_secret",
"BaseUrl": "https://open.feishu.cn"
},
"ConnectionStrings": {
"DefaultConnection": "Server=localhost;Database=OrganizationSync;Trusted_Connection=true;"
}
}

复制代码

在 Program.cs 中注册服务：

using Mud.Feishu;
var builder = WebApplication.CreateBuilder(args);
// 注册飞书 API 服务
builder.Services.AddFeishuApiService(builder.Configuration);
// 注册数据库上下文
builder.Services.AddDbContext<OrganizationDbContext>(options =>
options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection")));
// 注册同步服务
builder.Services.AddScoped<IFeishuSyncService, FeishuSyncService>();
builder.Services.AddHostedService<FeishuFullSyncService>();
var app = builder.Build();

复制代码

三、核心架构与同步模式设计

领域模型设计

设计本地数据库表结构，确保与飞书数据的有效映射：

// 部门实体
public class Department
{
public int Id { get; set; }
public string FeishuDepartmentId { get; set; } // 飞书部门ID，用于关联
public string Name { get; set; }
public string? ParentFeishuDepartmentId { get; set; }
public int SortOrder { get; set; }
public bool IsActive { get; set; }
public DateTime CreatedAt { get; set; }
public DateTime UpdatedAt { get; set; }
// 导航属性
public virtual Department? ParentDepartment { get; set; }
public virtual ICollection<Department> SubDepartments { get; set; } = new List<Department>();
public virtual ICollection<User> Users { get; set; } = new List<User>();
}
// 用户实体
public class User
{
public int Id { get; set; }
public string FeishuUserId { get; set; } // 飞书用户ID，用于关联
public string Name { get; set; }
public string? Email { get; set; }
public string? Mobile { get; set; }
public string? EmployeeNumber { get; set; }
public int? DepartmentId { get; set; }
public bool IsActive { get; set; }
public DateTime CreatedAt { get; set; }
public DateTime UpdatedAt { get; set; }
// 导航属性
public virtual Department? Department { get; set; }
}

复制代码

EF Core DbContext配置：

public class OrganizationDbContext : DbContext
{
public OrganizationDbContext(DbContextOptions<OrganizationDbContext> options)
: base(options)
{
}
public DbSet<Department> Departments { get; set; }
public DbSet<User> Users { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
// 为飞书ID创建唯一索引
modelBuilder.Entity<Department>()
.HasIndex(d => d.FeishuDepartmentId)
.IsUnique();
modelBuilder.Entity<User>()
.HasIndex(u => u.FeishuUserId)
.IsUnique();
// 配置部门层级关系
modelBuilder.Entity<Department>()
.HasOne(d => d.ParentDepartment)
.WithMany(d => d.SubDepartments)
.HasForeignKey(d => d.ParentFeishuDepartmentId)
.HasPrincipalKey(d => d.FeishuDepartmentId);
}
}

复制代码

同步模式设计

模式一：全量同步（使用 BackgroundService）
适用于系统初始化或夜间批量同步的场景。通过递归方式获取完整的组织架构：

public class FeishuFullSyncService : BackgroundService
{
private readonly ILogger<FeishuFullSyncService> _logger;
private readonly IFeishuSyncService _syncService;
private readonly IServiceScopeFactory _scopeFactory;
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
while (!stoppingToken.IsCancellationRequested)
{
try
{
using var scope = _scopeFactory.CreateScope();
_logger.LogInformation("开始执行全量同步任务");
await _syncService.FullSyncDepartmentsAsync();
await _syncService.FullSyncUsersAsync();
_logger.LogInformation("全量同步任务完成");
// 每天凌晨2点执行
var nextRun = DateTime.Today.AddDays(1).AddHours(2);
var delay = nextRun - DateTime.Now;
await Task.Delay(delay, stoppingToken);
}
catch (Exception ex)
{
_logger.LogError(ex, "全量同步任务执行失败");
await Task.Delay(TimeSpan.FromHours(1), stoppingToken);
}
}
}
}

复制代码

模式二：增量/事件同步（创建ASP.NET Core Web API 控制器）
适用于实时性要求高的场景，通过飞书事件订阅实现：

[ApiController]
[Route("api/[controller]")]
public class FeishuEventController : ControllerBase
{
private readonly ILogger<FeishuEventController> _logger;
private readonly IFeishuSyncService _syncService;
[HttpPost("webhook")]
public async Task<IActionResult> HandleEvent([FromBody] FeishuEventRequest request)
{
try
{
// 验证事件签名
if (!ValidateSignature(request))
return Unauthorized();
// 根据事件类型处理
switch (request.Header.EventType)
{
case "contact.user.updated":
await _syncService.SyncUserAsync(request.Event.UserId);
break;
case "contact.department.updated":
await _syncService.SyncDepartmentAsync(request.Event.DepartmentId);
break;
// 其他事件类型...
}
return Ok(new { code = 0, msg: "success" });
}
catch (Exception ex)
{
_logger.LogError(ex, "处理飞书事件失败");
return BadRequest(new { code = -1, msg: ex.Message });
}
}
private bool ValidateSignature(FeishuEventRequest request)
{
// 实现飞书事件签名验证逻辑
// 参考：https://open.feishu.cn/document/server-docs/event-subscription-guides/event-verification
return true;
}
}

复制代码

混合模式（推荐）： 启动时全量同步 + 运行时事件同步 + 每日定时全量同步兜底。这种模式既保证了数据的一致性，又具备良好的实时性。
四、分步实现指南

步骤一：构建飞书API客户端

创建 FeishuApiService 类，封装飞书API调用：

public interface IFeishuApiService
{
Task<List<FeishuDepartment>> GetDepartmentsAsync();
Task<List<FeishuUser>> GetUsersByDepartmentAsync(string departmentId);
Task<FeishuUser?> GetUserByIdAsync(string userId);
}
public class FeishuApiService : IFeishuApiService
{
private readonly IFeishuV3DepartmentsApi _departmentsApi;
private readonly IFeishuV3UserApi _userApi;
private readonly ILogger<FeishuApiService> _logger;
public FeishuApiService(
IFeishuV3DepartmentsApi departmentsApi,
IFeishuV3UserApi userApi,
ILogger<FeishuApiService> logger)
{
_departmentsApi = departmentsApi;
_userApi = userApi;
_logger = logger;
}
public async Task<List<FeishuDepartment>> GetDepartmentsAsync()
{
try
{
var result = await _departmentsApi.GetDepartmentByIdAsync("0"); // 获取根部门
if (result.Code == 0 && result.Data != null)
{
var departments = new List<FeishuDepartment>();
await ProcessDepartmentTree(result.Data, departments);
return departments;
}
throw new FeishuException($"获取部门列表失败: {result.Msg}");
}
catch (Exception ex)
{
_logger.LogError(ex, "获取部门列表异常");
throw;
}
}
public async Task<List<FeishuUser>> GetUsersByDepartmentAsync(string departmentId)
{
try
{
var users = new List<FeishuUser>();
var pageToken = "";
var pageSize = 50;
do
{
var result = await _userApi.GetUserByDepartmentIdAsync(
departmentId: departmentId,
page_size: pageSize,
page_token: string.IsNullOrEmpty(pageToken) ? null : pageToken);
if (result.Code == 0 && result.Data?.Items != null)
{
users.AddRange(result.Data.Items.Select(item => MapToFeishuUser(item)));
pageToken = result.Data.PageToken ?? "";
}
else
{
throw new FeishuException($"获取部门用户失败: {result.Msg}");
}
} while (!string.IsNullOrEmpty(pageToken));
return users;
}
catch (Exception ex)
{
_logger.LogError(ex, "获取部门用户异常，DepartmentId: {DepartmentId}", departmentId);
throw;
}
}
private async Task ProcessDepartmentTree(DepartmentData dept, List<FeishuDepartment> departments)
{
var feishuDept = MapToFeishuDepartment(dept);
departments.Add(feishuDept);
// 递归获取子部门
if (dept.SubDepartments != null)
{
foreach (var subDept in dept.SubDepartments)
{
await ProcessDepartmentTree(subDept, departments);
}
}
}
private FeishuDepartment MapToFeishuDepartment(DepartmentData dept) => new()
{
DepartmentId = dept.DepartmentId,
Name = dept.Name,
ParentDepartmentId = dept.ParentDepartmentId,
SortOrder = dept.Order
};
private FeishuUser MapToFeishuUser(UserData user) => new()
{
UserId = user.UserId,
Name = user.Name,
Email = user.Email,
Mobile = user.Mobile,
EmployeeNumber = user.EmployeeNumber,
DepartmentIds = user.DepartmentIds?.ToList() ?? new List<string>(),
IsActive = user.Status?.IsActive ?? false
};
}

复制代码

步骤二：实现数据映射与处理

创建DTO类用于数据转换，并使用AutoMapper进行映射：

// 飞书数据传输对象
public class FeishuDepartment
{
public string DepartmentId { get; set; } = string.Empty;
public string Name { get; set; } = string.Empty;
public string? ParentDepartmentId { get; set; }
public int SortOrder { get; set; }
}
public class FeishuUser
{
public string UserId { get; set; } = string.Empty;
public string Name { get; set; } = string.Empty;
public string? Email { get; set; }
public string? Mobile { get; set; }
public string? EmployeeNumber { get; set; }
public List<string> DepartmentIds { get; set; } = new();
public bool IsActive { get; set; }
}
// AutoMapper配置
public class MappingProfile : Profile
{
public MappingProfile()
{
CreateMap<FeishuDepartment, Department>()
.ForMember(dest => dest.FeishuDepartmentId, opt => opt.MapFrom(src => src.DepartmentId))
.ForMember(dest => dest.Id, opt => opt.Ignore())
.ForMember(dest => dest.CreatedAt, opt => opt.MapFrom(src => DateTime.UtcNow))
.ForMember(dest => dest.UpdatedAt, opt => opt.MapFrom(src => DateTime.UtcNow))
.ForMember(dest => dest.ParentDepartment, opt => opt.Ignore())
.ForMember(dest => dest.SubDepartments, opt => opt.Ignore())
.ForMember(dest => dest.Users, opt => opt.Ignore());
CreateMap<FeishuUser, User>()
.ForMember(dest => dest.FeishuUserId, opt => opt.MapFrom(src => src.UserId))
.ForMember(dest => dest.Id, opt => opt.Ignore())
.ForMember(dest => dest.CreatedAt, opt => opt.MapFrom(src => DateTime.UtcNow))
.ForMember(dest => dest.UpdatedAt, opt => opt.MapFrom(src => DateTime.UtcNow))
.ForMember(dest => dest.Department, opt => opt.Ignore());
}
}

复制代码

步骤三：实现全量同步服务

创建同步服务接口和实现：

public interface IFeishuSyncService
{
Task FullSyncDepartmentsAsync();
Task FullSyncUsersAsync();
Task SyncDepartmentAsync(string departmentId);
Task SyncUserAsync(string userId);
}
public class FeishuSyncService : IFeishuSyncService
{
private readonly IFeishuApiService _feishuApiService;
private readonly OrganizationDbContext _dbContext;
private readonly IMapper _mapper;
private readonly ILogger<FeishuSyncService> _logger;
public async Task FullSyncDepartmentsAsync()
{
_logger.LogInformation("开始全量同步部门");
try
{
// 获取飞书部门列表
var feishuDepartments = await _feishuApiService.GetDepartmentsAsync();
// 获取本地部门列表
var localDepartments = await _dbContext.Departments
.Where(d => d.IsActive)
.ToDictionaryAsync(d => d.FeishuDepartmentId);
var departmentsToAdd = new List<Department>();
var departmentsToUpdate = new List<Department>();
var departmentIdsToDeactivate = new HashSet<string>(localDepartments.Keys);
foreach (var feishuDept in feishuDepartments)
{
departmentIdsToDeactivate.Remove(feishuDept.DepartmentId);
if (localDepartments.TryGetValue(feishuDept.DepartmentId, out var localDept))
{
// 更新现有部门
_mapper.Map(feishuDept, localDept);
localDept.UpdatedAt = DateTime.UtcNow;
departmentsToUpdate.Add(localDept);
}
else
{
// 新增部门
var newDept = _mapper.Map<Department>(feishuDept);
newDept.IsActive = true;
departmentsToAdd.Add(newDept);
}
}
// 执行数据库操作
if (departmentsToAdd.Any())
{
_dbContext.Departments.AddRange(departmentsToAdd);
_logger.LogInformation("新增部门数量: {Count}", departmentsToAdd.Count);
}
if (departmentsToUpdate.Any())
{
_dbContext.Departments.UpdateRange(departmentsToUpdate);
_logger.LogInformation("更新部门数量: {Count}", departmentsToUpdate.Count);
}
// 逻辑删除不存在的部门
if (departmentIdsToDeactivate.Any())
{
var departmentsToDeactivate = await _dbContext.Departments
.Where(d => departmentIdsToDeactivate.Contains(d.FeishuDepartmentId))
.ToListAsync();
foreach (var dept in departmentsToDeactivate)
{
dept.IsActive = false;
dept.UpdatedAt = DateTime.UtcNow;
}
_logger.LogInformation("停用部门数量: {Count}", departmentsToDeactivate.Count);
}
await _dbContext.SaveChangesAsync();
_logger.LogInformation("部门全量同步完成");
}
catch (Exception ex)
{
_logger.LogError(ex, "部门全量同步失败");
throw;
}
}
public async Task FullSyncUsersAsync()
{
_logger.LogInformation("开始全量同步用户");
try
{
// 获取所有部门
var departments = await _dbContext.Departments
.Where(d => d.IsActive)
.ToListAsync();
var feishuUsers = new List<FeishuUser>();
// 遍历每个部门获取用户
foreach (var dept in departments)
{
try
{
var deptUsers = await _feishuApiService.GetUsersByDepartmentAsync(dept.FeishuDepartmentId);
feishuUsers.AddRange(deptUsers);
}
catch (Exception ex)
{
_logger.LogError(ex, "获取部门用户失败，DepartmentId: {DepartmentId}", dept.FeishuDepartmentId);
// 继续处理其他部门
}
}
// 去重（用户可能属于多个部门）
var uniqueUsers = feishuUsers.GroupBy(u => u.UserId).Select(g => g.First()).ToList();
// 获取本地用户列表
var localUsers = await _dbContext.Users
.Where(u => u.IsActive)
.ToDictionaryAsync(u => u.FeishuUserId);
var usersToAdd = new List<User>();
var usersToUpdate = new List<User>();
var userIdsToDeactivate = new HashSet<string>(localUsers.Keys);
foreach (var feishuUser in uniqueUsers)
{
userIdsToDeactivate.Remove(feishuUser.UserId);
if (localUsers.TryGetValue(feishuUser.UserId, out var localUser))
{
// 更新现有用户
_mapper.Map(feishuUser, localUser);
localUser.UpdatedAt = DateTime.UtcNow;
// 设置主部门（取第一个有效部门）
var primaryDept = departments.FirstOrDefault(d => feishuUser.DepartmentIds.Contains(d.FeishuDepartmentId));
if (primaryDept != null)
{
localUser.DepartmentId = primaryDept.Id;
}
usersToUpdate.Add(localUser);
}
else
{
// 新增用户
var newUser = _mapper.Map<User>(feishuUser);
newUser.IsActive = true;
// 设置主部门
var primaryDept = departments.FirstOrDefault(d => feishuUser.DepartmentIds.Contains(d.FeishuDepartmentId));
if (primaryDept != null)
{
newUser.DepartmentId = primaryDept.Id;
}
usersToAdd.Add(newUser);
}
}
// 执行数据库操作
if (usersToAdd.Any())
{
_dbContext.Users.AddRange(usersToAdd);
_logger.LogInformation("新增用户数量: {Count}", usersToAdd.Count);
}
if (usersToUpdate.Any())
{
_dbContext.Users.UpdateRange(usersToUpdate);
_logger.LogInformation("更新用户数量: {Count}", usersToUpdate.Count);
}
// 逻辑删除不存在的用户
if (userIdsToDeactivate.Any())
{
var usersToDeactivate = await _dbContext.Users
.Where(u => userIdsToDeactivate.Contains(u.FeishuUserId))
.ToListAsync();
foreach (var user in usersToDeactivate)
{
user.IsActive = false;
user.UpdatedAt = DateTime.UtcNow;
}
_logger.LogInformation("停用用户数量: {Count}", usersToDeactivate.Count);
}
await _dbContext.SaveChangesAsync();
_logger.LogInformation("用户全量同步完成");
}
catch (Exception ex)
{
_logger.LogError(ex, "用户全量同步失败");
throw;
}
}
public async Task SyncDepartmentAsync(string departmentId)
{
// 实现单个部门的增量同步
// 类似于全量同步的逻辑，但只处理指定部门
throw new NotImplementedException();
}
public async Task SyncUserAsync(string userId)
{
// 实现单个用户的增量同步
// 类似于全量同步的逻辑，但只处理指定用户
throw new NotImplementedException();
}
}

复制代码

步骤四：实现增量事件同步

创建事件处理器来处理飞书的实时事件：

public class FeishuEventHandler
{
private readonly IFeishuSyncService _syncService;
private readonly ILogger<FeishuEventHandler> _logger;
public async Task HandleUserUpdatedEvent(FeishuEventPayload payload)
{
try
{
var userId = payload.UserId;
_logger.LogInformation("处理用户更新事件，UserId: {UserId}", userId);
await _syncService.SyncUserAsync(userId);
_logger.LogInformation("用户更新事件处理完成，UserId: {UserId}", userId);
}
catch (Exception ex)
{
_logger.LogError(ex, "处理用户更新事件失败，UserId: {UserId}", payload.UserId);
throw;
}
}
public async Task HandleDepartmentUpdatedEvent(FeishuEventPayload payload)
{
try
{
var departmentId = payload.DepartmentId;
_logger.LogInformation("处理部门更新事件，DepartmentId: {DepartmentId}", departmentId);
await _syncService.SyncDepartmentAsync(departmentId);
_logger.LogInformation("部门更新事件处理完成，DepartmentId: {DepartmentId}", departmentId);
}
catch (Exception ex)
{
_logger.LogError(ex, "处理部门更新事件失败，DepartmentId: {DepartmentId}", payload.DepartmentId);
throw;
}
}
}

复制代码

步骤五：处理边界情况与异常

使用Polly库实现重试和熔断策略：

public class ResilientFeishuApiService : IFeishuApiService
{
private readonly IFeishuApiService _innerService;
private readonly IAsyncPolicy _retryPolicy;
private readonly IAsyncPolicy _circuitBreakerPolicy;
public ResilientFeishuApiService(IFeishuApiService innerService)
{
_innerService = innerService;
_retryPolicy = Policy
.Handle<FeishuException>(ex => ex.ErrorCode >= 500) // 服务器错误重试
.Or<HttpRequestException>() // 网络错误重试
.WaitAndRetryAsync(
retryCount: 3,
sleepDurationProvider: retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt)),
onRetry: (outcome, timespan, retryAttempt, context) =>
{
Console.WriteLine($"重试第 {retryAttempt} 次，延迟 {timespan.TotalSeconds} 秒");
});
_circuitBreakerPolicy = Policy
.Handle<FeishuException>()
.CircuitBreakerAsync(
exceptionsAllowedBeforeBreaking: 5,
durationOfBreak: TimeSpan.FromMinutes(1),
onBreak: (ex, breakDelay) =>
{
Console.WriteLine($"熔断器开启，延迟 {breakDelay.TotalMinutes} 分钟");
},
onReset: () =>
{
Console.WriteLine("熔断器重置");
});
}
public async Task<List<FeishuDepartment>> GetDepartmentsAsync()
{
return await _retryPolicy.ExecuteAsync(() =>
_circuitBreakerPolicy.ExecuteAsync(() => _innerService.GetDepartmentsAsync()));
}
// 其他方法类似实现...
}

复制代码

五、进阶功能与.NET最佳实践

依赖注入与配置

使用选项模式管理配置，实现配置的强类型化和验证：

public class FeishuSyncOptions
{
public int PageSize { get; set; } = 50;
public TimeSpan SyncInterval { get; set; } = TimeSpan.FromHours(24);
public int MaxRetryAttempts { get; set; } = 3;
public bool EnableEventSync { get; set; } = true;
}
// 在Program.cs中注册
builder.Services.Configure<FeishuSyncOptions>(builder.Configuration.GetSection("FeishuSync"));
builder.Services.AddScoped<IFeishuSyncService, FeishuSyncService>();

复制代码

日志与监控

集成结构化日志和监控：

public class FeishuSyncService : IFeishuSyncService
{
private readonly ILogger<FeishuSyncService> _logger;
private readonly IMetrics _metrics;
public async Task FullSyncDepartmentsAsync()
{
using var activity = Activity.StartActivity("feishu_sync_departments_full");
var stopwatch = Stopwatch.StartNew();
try
{
_logger.LogInformation("开始全量同步部门，ActivityId: {ActivityId}", Activity.Current?.Id);
// 同步逻辑...
stopwatch.Stop();
_metrics.Counter("feishu_sync_departments_success").Add(1);
_metrics.Histogram("feishu_sync_departments_duration").Record(stopwatch.ElapsedMilliseconds);
_logger.LogInformation("部门全量同步完成，耗时: {ElapsedMs}ms", stopwatch.ElapsedMilliseconds);
}
catch (Exception ex)
{
_metrics.Counter("feishu_sync_departments_failed").Add(1);
_logger.LogError(ex, "部门全量同步失败");
throw;
}
}
}

复制代码

实现飞书扫码登录（SSO）

基于已有的同步数据，实现飞书OAuth登录：

public class FeishuAuthenticationHandler : AuthenticationHandler
{
private readonly IFeishuV3AuthenticationApi _authApi;
private readonly IUserService _userService;
protected override async Task HandleAuthenticateAsync()
{
if (!Request.Headers.ContainsKey("Authorization"))
return AuthenticateResult.Fail("Missing Authorization Header");
try
{
var token = Request.Headers["Authorization"].ToString().Replace("Bearer ", "");
// 获取用户信息
var userInfo = await _authApi.GetUserInfoAsync(token);
if (userInfo.Code != 0)
return AuthenticateResult.Fail("Invalid token");
// 在本地数据库中查找用户
var user = await _userService.GetByFeishuUserIdAsync(userInfo.Data.UserId);
if (user == null || !user.IsActive)
return AuthenticateResult.Fail("User not found or inactive");
// 创建身份票据
var claims = new[]
{
new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
new Claim(ClaimTypes.Name, user.Name),
new Claim(ClaimTypes.Email, user.Email ?? ""),
new Claim("feishu_user_id", user.FeishuUserId)
};
var identity = new ClaimsIdentity(claims, Scheme.Name);
var principal = new ClaimsPrincipal(identity);
var ticket = new AuthenticationTicket(principal, Scheme.Name);
return AuthenticateResult.Success(ticket);
}
catch (Exception ex)
{
return AuthenticateResult.Fail($"Authentication failed: {ex.Message}");
}
}
}

复制代码

部署与运维

Docker化部署：

FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /src
COPY ["OrganizationSync/OrganizationSync.csproj", "OrganizationSync/"]
RUN dotnet restore "OrganizationSync/OrganizationSync.csproj"
COPY . .
WORKDIR "/src/OrganizationSync"
RUN dotnet build "OrganizationSync.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "OrganizationSync.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "OrganizationSync.dll"]

复制代码

健康检查：

public class FeishuSyncHealthCheck : IHealthCheck
{
private readonly IFeishuApiService _feishuApiService;
private readonly OrganizationDbContext _dbContext;
public async Task<HealthCheckResult> CheckHealthAsync(
HealthCheckContext context,
CancellationToken cancellationToken = default)
{
try
{
// 检查飞书API连接
var departments = await _feishuApiService.GetDepartmentsAsync();
// 检查数据库连接
var userCount = await _dbContext.Users.CountAsync(cancellationToken);
var data = new Dictionary<string, object>
{
{ "department_count", departments.Count },
{ "local_user_count", userCount },
{ "last_sync", DateTime.UtcNow }
};
return HealthCheckResult.Healthy("飞书同步服务运行正常", data);
}
catch (Exception ex)
{
return HealthCheckResult.Unhealthy("飞书同步服务异常", ex);
}
}
}

复制代码

六、总结
