xlgo 是一个基于 Go + Gin 的轻量级 Web 开发框架，提供了完整的后端开发基础设施，包括配置管理、数据库访问、缓存、认证、日志、文件存储等常用功能。
## 框架特性
- **配置管理** - 支持 YAML 配置文件，环境变量覆盖，配置热更新
- **数据库** - MySQL + GORM，支持自动迁移、重试机制、连接池、读写分离
- **缓存** - Redis 缓存，支持分布式缓存、键前缀、TTL，SCAN 优化
- **认证** - JWT 认证，支持 Token 黑名单、刷新机制
- **日志** - 分级日志（API、数据库），日志轮转
- **中间件** - CORS、限流、日志、认证、CSRF 防护
- **文件存储** - 本地存储 + 阿里云 OSS 支持
- **实时通信** - SSE 流式响应 + WebSocket 支持
- **定时任务** - 内置任务调度器
- **验证器** - 请求参数验证，支持自定义错误消息
- **错误处理** - 统一错误码体系
- **CLI 工具** - 脚手架工具，快速创建项目和代码
## 快速开始
### 1. 安装
```bash
# 安装脚手架工具
go install github.com/EthanCodeCraft/xlgo-core/cmd/xlgo@latest
# 创建新项目
xlgo new myproject
# 进入目录
cd myproject
# 安装依赖
go mod tidy
```
### 2. 创建配置文件 config.yaml
```yaml
server:
port: 8080
mode: development
database:
host: localhost
port: 3306
user: root
password: your_password
name: your_database
max_idle_conns: 10
max_open_conns: 100
redis:
host: localhost
port: 6379
password: ""
db: 0
jwt:
secret: your_jwt_secret_key
expire: 86400
storage:
driver: local
local:
path: ./public
base_url: http://localhost:8080/public
log:
dir: ./logs
max_size: 100
max_backups: 30
max_age: 30
compress: true
```
### 3. 运行项目
```bash
go run main.go
```
访问 http://localhost:8080/health 检查服务状态。
---
## 核心功能
### 配置管理
```go
// 加载配置
cfg, err := config.Load("./config.yaml")
// 获取配置
cfg := config.Get()
serverPort := cfg.Server.Port
// 配置热更新
cfg, err := config.LoadWithWatch("./config.yaml", func(newCfg *config.Config) {
log.Println("配置已更新")
})
// 注册配置变更回调
config.RegisterCallback(func(cfg *config.Config) {
// 处理配置变更
})
// 手动重新加载
config.Reload()
```
### 数据库操作
```go
// 初始化 MySQL
database.InitMySQL(cfg)
defer database.Close()
// 主从读写分离
database.InitMySQLWithReplicas(cfg, []string{
"root:pass@tcp(slave1:3306)/db",
"root:pass@tcp(slave2:3306)/db",
})
// 读操作自动路由到从库
users := database.GetReadDB().Find(&users)
// 强制使用主库
ctx := database.UseMaster(context.Background())
database.GetDBFromContext(ctx).Find(&users)
// 事务
database.Transaction(func(tx *gorm.DB) error {
return tx.Create(&user).Error
})
// 健康检查
status := database.HealthCheck()
```
### Repository 泛型 CRUD
```go
// 创建仓库
userRepo := repository.NewBaseRepo[model.User](database.GetDB())
// 基础 CRUD
user, err := userRepo.FindByID(ctx, 1)
err := userRepo.Create(ctx, &user)
err := userRepo.Update(ctx, &user)
err := userRepo.Delete(ctx, 1)
// 分页查询
result, err := userRepo.FindPage(ctx, 1, 20)
// result.Items, result.Total, result.Page, result.PageSize
// 条件查询
users, err := userRepo.FindWhere(ctx, "status = ?", 1)
// 链式查询
users, err := userRepo.NewQueryBuilder().
Where("status = ?", 1).
Order("created_at DESC").
Limit(10).
Find(ctx)
// 批量操作
err := userRepo.CreateBatch(ctx, users)
err := userRepo.DeleteBatch(ctx, []uint{1, 2, 3})
// 事务支持
err := userRepo.WithTransaction(ctx, func(txRepo *repository.BaseRepo[model.User]) error {
return txRepo.Create(ctx, &user)
})
```
### Redis 缓存
```go
// 初始化缓存
cache.Init()
// 使用缓存
ctx := context.Background()
cacheService := cache.GetCache()
// 设置缓存
cacheService.Set(ctx, "user:1", user, 10*time.Minute)
// 获取缓存
var user User
if cacheService.Get(ctx, "user:1", &user) {
// 缓存命中
}
// 删除缓存
cacheService.Delete(ctx, "user:1")
// 按模式删除（使用 SCAN 优化）
cacheService.DeleteByPattern(ctx, "user:*")
```
### JWT 认证
```go
// 生成 Token（自动包含 JTI）
token, err := jwt.GenerateToken(userID, username, "admin", "admin")
// 解析 Token
claims, err := jwt.ParseToken(tokenString)
// 使 Token 失效（使用 JTI，高效）
jwt.InvalidateToken(tokenString)
// 获取 Token 的 JTI
jti, err := jwt.GetJTI(tokenString)
```
**JWT 黑名单优化**：使用 JTI（JWT ID）替代完整 Token 存储，大幅节省 Redis 内存。
### 分布式锁
```go
// 安全加锁（返回 LockToken）
token, err := cache.NewLock(ctx, cache.KLock("order:123"), 30*time.Second)
if token != nil {
defer cache.Unlock(ctx, token) // 只有持有者能释放
// 执行业务逻辑
}
// 续期锁（长任务场景）
cache.ExtendLock(ctx, token, 30*time.Second)
// 自动续期执行
err := cache.WithLockAutoExtend(ctx, key, 30*time.Second, 10*time.Second, func() error {
// 长任务自动续期
return nil
})
```
**分布式锁安全特性**：使用 Lua 脚本 + UUID Token，只有锁的持有者才能释放。
### Redis 分布式限流
```go
// 内存限流（单实例）
r.Use(middleware.CustomRateLimit(100, time.Minute))
// Redis 分布式限流（多实例共享）
r.Use(middleware.RedisRateLimit("api_limit", 100))
r.Use(middleware.LoginRedisRateLimit()) // 登录限流
r.Use(middleware.APIRedisRateLimit()) // API 限流
```
### 请求验证
```go
type LoginRequest struct {
Username string `json:"username" label:"用户名" validate:"required,username" msg_required:"请输入用户名"`
Password string `json:"password" label:"密码" validate:"required,password" error:"密码格式不正确"`
Phone string `json:"phone" label:"手机号" validate:"omitempty,phone" msg_phone:"请输入正确的手机号"`
}
// 绑定并验证
errors, ok := validation.ShouldBindAndValidate(c, &req)
if !ok {
response.Fail(c, errors.FirstMessage())
return
}
```
**验证器支持的自定义标签**：
- `label:"中文名"` - 字段显示名称
- `error:"通用错误消息"` - 所有验证失败时显示
- `msg_required:"必填项"` - 特定规则的错误消息
- `msg_min:"最少5个字符"` - 针对 min 规则的错误消息
### 统一错误码
```go
// 使用预定义错误
response.FailWithError(c, response.ErrUserNotFound)
// 带详细信息
response.FailWithDetail(c, response.ErrPasswordWrong, "连续错误3次将锁定账户")
// 自定义错误
err := response.NewError(10001, "自定义错误")
```
**预定义错误码**：
- 用户模块：`ErrUserNotFound`, `ErrPasswordWrong`, `ErrTokenExpired` 等
- 文件模块：`ErrFileTooLarge`, `ErrFileTypeInvalid` 等
- 数据模块：`ErrDataNotFound`, `ErrDataConflict` 等
### 文件上传
```go
// 上传文件
file, err := c.FormFile("file")
path, err := storage.Upload(file, "images")
url := storage.GetURL(path)
// 上传字节数组
path, err := storage.UploadFromBytes(data, "filename.jpg", "images")
// 删除文件
err := storage.Delete(path)
// 获取文件内容
data, err := storage.Get(path)
// 检查文件是否存在
exists := storage.Exists(path)
```
### SSE 流式响应
```go
// AI 对话场景
func ChatHandler(c *gin.Context) {
ch := make(chan string)
go func() {
defer close(ch)
for _, chunk := range aiResponse {
ch <- chunk
}
}()
sse.StreamChunks(c, ch)
}
// 带消息 ID 的流式响应
sse.StreamWithID(c, "msg_123", ch)
```
### WebSocket
```go
// 简单使用
r.GET("/ws", ws.HandleFunc(func(conn *ws.Connection, message []byte) {
conn.SendText("收到: " + string(message))
}))
// 广播模式
hub := ws.NewHub()
go hub.Run()
hub.Broadcast([]byte("广播消息"))
```
### 定时任务
```go
// 每隔 5 分钟执行
cron.AddTask("cleanup", cron.Every(5*time.Minute), func(ctx context.Context) error {
return cleanupOldData()
})
// 每天凌晨 2 点执行
cron.AddTask("daily_report", cron.Daily(2, 0), generateReport)
// 每周一上午 9 点执行
cron.AddTask("weekly", cron.Weekly(time.Monday, 9, 0), weeklyTask)
// 完整 Cron 表达式
cron.AddTask("every15min", cron.ParseCron("*/15 * * * *"), doSomething)
cron.AddTask("monthly", cron.ParseCron("0 0 1 * *"), doSomething) // 每月1号
// 启动调度器
cron.Start()
defer cron.Stop()
```
### CSRF 防护
```go
// 基本使用
r.Use(middleware.CSRF())
// 获取 Token（返回给前端）
token := middleware.GetCSRFToken(c)
// 跳过指定路径
r.Use(middleware.CSRFWithSkip([]string{"/api/webhook"}))
// API 模式（双重提交 Cookie）
r.Use(middleware.DoubleSubmitCookie())
```
### 密码加密
```go
// 加密密码
hash, err := validation.HashPassword("password123")
// 验证密码
if validation.CheckPassword(hash, "password123") {
// 密码正确
}
// 带成本升级的验证
match, needUpgrade, newHash, err := validation.CheckPasswordAndUpgrade(hash, password, 12)
```
---
## 中间件
### 认证中间件
```go
// JWT 认证（必须登录）
r.Use(middleware.AuthRequired())
// 管理员权限
r.Use(middleware.AdminRequired())
// 超级管理员权限
r.Use(middleware.SuperAdminRequired())
// 员工权限
r.Use(middleware.StaffRequired())
// 任意用户（管理员或员工）
r.Use(middleware.AnyUserRequired())
// 获取用户信息
userID := middleware.GetUserID(c)
username := middleware.GetUsername(c)
userType := middleware.GetUserType(c)
```
### 限流中间件
```go
// 登录限流（每分钟 10 次）
r.POST("/login", middleware.LoginRateLimit(), handler.Login)
// 上传限流（每分钟 20 次）
r.POST("/upload", middleware.UploadRateLimit(), handler.Upload)
// 自定义限流
r.Use(middleware.CustomRateLimit(50, time.Minute))
// 停止限流器（应用关闭时）
defer middleware.StopRateLimiters()
```
---
## 响应格式
框架使用统一的响应格式：
```json
{
"code": 1,
"msg": "操作成功",
"data": {},
"request_id": "abc123"
}
```
```go
// 成功响应
response.Success(c, data)
response.SuccessWithMsg(c, "自定义消息", data)
// 失败响应
response.Fail(c, "错误消息")
// 分页响应
response.Page(c, list, total, page, pageSize)
// 错误响应
response.Unauthorized(c, "请先登录")
response.NotFound(c, "资源不存在")
response.ServerError(c, "服务器错误")
response.RateLimit(c)
```
---
## CLI 工具
```bash
# 创建新项目
xlgo new myproject
# 创建新项目并指定模块路径
xlgo new myproject --module github.com/myorg/myproject
# 生成代码
xlgo make handler user # 创建 handler/user.go
xlgo make repository user # 创建 repository/user_repository.go
xlgo make model user # 创建 model/user.go
xlgo make service user # 创建 service/user_service.go
# 显示版本
xlgo version
```
---
## 测试
框架提供完整的测试工具包：
```go
func TestUserAPI(t *testing.T) {
router := test.SetupRouter()
// 创建请求
resp := test.POST(router, "/api/v1/users").
WithJSON(map[string]any{"name": "test"}).
WithToken("xxx").
Execute()
// 断言
resp.AssertOK(t)
// 解析响应
var result map[string]any
resp.ParseJSON(&result)
}
```
