# 文件快传 Go 后端（server/）
|
||||
|
||||
Go 1.27.1 + Gin + GORM 重写的文件快传后端。数据库**默认 SQLite**（modernc.org/sqlite
|
||||
纯 Go 驱动，CGO_ENABLED=0 交叉编译友好，零外部依赖），配置 `FCB_DB_DRIVER=postgres` 后
|
||||
切换 Postgres（需求 ⑧）；Redis 为**可选**增强（未配置 `FCB_REDIS_ADDR` 时自动降级为进程内存缓存）。
|
||||
|
||||
## 目录结构
|
||||
|
||||
```
|
||||

|
||||

```
|
||||
|
||||
## 环境变量
|
||||
|
||||
| 变量 | 必需 | 默认 | 说明 |
|
||||
|---|---|---|---|
|
||||
| `FCB_DB_DRIVER` | ❌ | `sqlite` | 数据库驱动：`sqlite` \| `postgres`（需求 ⑧） |
|
||||
| `FCB_DB_DSN` | 视驱动 | `./data/filecodebox.db` | postgres：连接串（**必需**），如 `postgres://user:pass@host:5432/filecodebox?sslmode=disable`；sqlite：数据库文件路径（可空，自动创建 `data/` 目录） |
|
||||
| `FCB_REDIS_ADDR` | ❌ | 空 | 为空时缓存降级为内存实现 |
|
||||
| `FCB_LISTEN` | ❌ | `:8466` | 监听地址 |
|
||||
| `FCB_STORAGE_ENGINE` | ❌ | `local` | `local` \| `s3` \| `webdav` |
|
||||
| `FCB_TRUSTED_PROXIES` | ❌ | 空 | 可信代理 CIDR（逗号分隔），用于解析真实客户端 IP |
|
||||
|
||||
### 数据库模式（需求 ⑧）
|
||||
|
||||
- **SQLite（默认）**：`FCB_DB_DRIVER=sqlite`（或缺省）。零 DSN 零依赖启动，数据库文件
|
||||
默认 `./data/filecodebox.db`（`FCB_DB_DSN` 可覆盖路径；父目录自动创建）。
|
||||
连接参数：`busy_timeout=10s` + `WAL` 日志模式 + `foreign_keys=1`（通过 DSN pragma 注入）。
|
||||
- **Postgres（可选）**：`FCB_DB_DRIVER=postgres` 且必须提供 `FCB_DB_DSN`，否则启动报错。
|
||||
连接池沿用 v1 参数（32/8、1h 轮换）。
|
||||
- 双方言共用 GORM 抽象：AutoMigrate、settings KV、全部业务查询方言无关；
|
||||
唯一原生 DDL（migrates 台账表）在 `database.createMigratesTable` 内部分支处理。
|
||||
|
||||
## v2 新增配置键（internal/config/schema.go 为单一事实来源）
|
||||
|
||||
| 键 | 类型 | 默认 | 说明 |
|
||||
|---|---|---|---|
|
||||
| `background_url` | string | `""` | 需求 ①：背景图 URL/上传地址（空=主题默认；legacy `background` 键兜底） |
|
||||
| `footer_text` | string | `""` | 需求 ②：页脚自定义内容（≤2000 字符） |
|
||||
| `footer_beian` | string | `""` | 需求 ②：备案号（≤128 字符） |
|
||||
| `notify_enabled` | int | `1` | 需求 ③：通知开关（1 开 / 0 关） |
|
||||
| `notify_title` / `notify_content` | string | 见 defaults | 需求 ③：通知标题/内容（沿用参考实现语义） |
|
||||
| `max_save_seconds` | int64 | `0` | 需求 ④：最长保存秒数上限（0=仅默认 7 天兜底，≤365 天） |
|
||||
| `max_save_count` | int | `0` | 需求 ④：单次分享最大可取次数上限（0=不限制，≤100000） |
|
||||
| `max_file_size` | int64 | `0` | 需求 ⑩：存储策略-单文件上限字节（0=回落 `uploadSize`，≤10GiB） |
|
||||
| `uploadSize` / `allowed_file_types` / `storageLimit` / `openUpload` | 既有 | - | 存储策略既有键（语义不变） |
|
||||
| `uploadCount` / `uploadMinute` | 既有 | `10` / `1` | 上传频率限制（对齐参考 `ip_limit["upload"]`） |
|
||||
|
||||
管理端与文档（t2/t4）以 `config.KVSchema()`（`settings.KVSchema()` re-export）为元数据源；
|
||||
schema 同步测试保证 `KVSchema()` 与 `defaults()` 逐键一致。
|
||||
|
||||
## 数据模型
|
||||
|
||||
- `file_codes`：文件/文本分享（对齐参考 `apps/base/models.py::FileCodes`）
|
||||
- `upload_chunks`：分片上传记录
|
||||
- `key_values`：运行时配置 KV（`settings` / `sys_start` 键）
|
||||
- `presign_upload_sessions`：预签名直传会话
|
||||
- `storage_reservations`：上传容量预留
|
||||
- `audit_logs`：上传/下载审计（时间/IP/UA/设备/动作/结果/字节数/耗时），需求 ③
|
||||
- `migrates`：迁移台账表（双方言 DDL 分支，见 `database.createMigratesTable`）
|
||||
|
||||
## 存储引擎契约（internal/storage/interface.go）
|
||||
|
||||
`go-storage` 按此契约实现 local/s3/webdav 三引擎（**接口签名已冻结**）：
|
||||
|
||||
```go
|
||||
type Storage interface {
|
||||
SaveFile(ctx, r io.Reader, savePath) (int64, error) // 流式保存
|
||||
DeleteFile(ctx, savePath) error
|
||||
Open(ctx, savePath, rng *Range) (*Download, error) // Range 下载
|
||||
Stat(ctx, savePath) (*FileMeta, error)
|
||||
SaveChunk(ctx, uploadID, chunkIndex, r io.Reader, savePath) (int64, error)
|
||||
MergeChunks(ctx, uploadID, total, verifyHash, savePath) (int64, string, error)
|
||||
CleanChunks(ctx, uploadID, savePath) error
|
||||
FileExists(ctx, savePath) (bool, error)
|
||||
PresignGetURL(ctx, savePath, expires) (string, error) // 不支持→ErrNotSupported
|
||||
PresignPutURL(ctx, savePath, expires) (string, error)
|
||||
HealthCheck(ctx) error
|
||||
}
|
||||
```
|
||||
|
||||
错误映射约定：`ErrNotFound`→404、`ErrInvalidPath`→400、`ErrUnavailable`→503、`ErrNotSupported`→501、`ErrRangeNotSatisfiable`→416。
|
||||
|
||||
引擎通过 `storage.RegisterEngine("local"|"s3"|"webdav", factory)` 注册，
|
||||
`storage.NewEngine(ctx, name)` 构造。分片路径约定：`<父目录>/chunks/<uploadID>/<index>.part`。
|
||||
|
||||
### 引擎构造选项（t3 API 层接入）
|
||||
|
||||
构造引擎前必须先注入选项（否则 local 退到系统临时目录、s3/webdav 因缺配置失败）：
|
||||
|
||||
```go
|
||||
storage.SetEngineOptions(storage.EngineOptions{
|
||||
Local: storage.LocalOptions{Root: cfg.GetString("local_storage_path")},
|
||||
S3: storage.S3Options{
|
||||
AccessKeyID: cfg.GetString("s3_access_key_id"), SecretAccessKey: cfg.GetString("s3_secret_access_key"),
|
||||
Bucket: cfg.GetString("s3_bucket_name"), Endpoint: cfg.GetString("s3_endpoint_url"),
|
||||
Region: cfg.GetString("s3_region_name"), AddressingStyle: cfg.GetString("s3_addressing_style"),
|
||||
},
|
||||
WebDAV: storage.WebDAVOptions{
|
||||
BaseURL: cfg.GetString("webdav_url"), Username: cfg.GetString("webdav_username"),
|
||||
Password: cfg.GetString("webdav_password"), RootPath: cfg.GetString("webdav_root_path"),
|
||||
},
|
||||
})
|
||||
st, err := storage.NewEngine(ctx, cfg.Engine()) // 构造后调 st.HealthCheck(ctx) 完成启动自检
|
||||
```
|
||||
|
||||
引擎要点：local 原子写（临时文件+fsync+rename）、防穿越+符号链接逃逸校验；
|
||||
s3 原生 multipart 流式合并、预签名直链、SDK 内置 5xx 重试；webdav 连接池复用、
|
||||
Basic/Digest 自动协商、Range 透传、按需逐级 MKCOL（带缓存）、5xx/429 指数退避重试、
|
||||
下载 io.Pipe 流式不落盘。三引擎均支持分片上传/合并（SHA256 校验）与 Range 下载。
|
||||
|
||||
## 审计埋点用法（API 层）
|
||||
|
||||
```go
|
||||
r.Use(middleware.Audit(auditSvc, nil)) // nil=默认按路由前缀分类 upload/download
|
||||
|
||||
// handler 内填充业务字段并显式落库（推荐）：
|
||||
middleware.AuditSet(c, func(e *audit.Entry) { e.FileCode = code; e.FileName = name })
|
||||
middleware.AuditRecordRequest(c, auditSvc, model.AuditResultSuccess, "")
|
||||
// 或不显式落库：中间件按 HTTP 状态兜底（4xx/5xx→failed，401/403/423/429/428→denied）
|
||||
```
|
||||
|
||||
下载响应字节数由中间件自动统计；上传字节数由 handler 填 `TransferredBytes`。
|
||||
|
||||
## 限流语义（对齐参考实现）
|
||||
|
||||
- `error`（取件错误）/`login`（登录失败）：**仅在失败时计数**，handler 调用 `limiter.Add(c, kind)`
|
||||
- `upload`：**成功上传才计数**（先 `Check` 放行，成功后 `Add`）
|
||||
- `metadata`：每次访问即计数，可用 `RequireRateLimit` 中间件
|
||||
- 超限返回 HTTP 423；规则来自 settings KV（errorCount/errorMinute 等），可运行时调整
|
||||
|
||||
## 本地开发
|
||||
|
||||
```bash
|
||||
# 默认 SQLite 模式：零依赖，数据库落 ./data/filecodebox.db
|
||||
go run ./cmd/server # 启动于 :8466
|
||||
curl localhost:8466/api/v1/health
|
||||
|
||||
# Postgres 模式（可选）
|
||||
export FCB_DB_DRIVER=postgres
|
||||
export FCB_DB_DSN='postgres://postgres:postgres@localhost:5432/filecodebox?sslmode=disable'
|
||||
go run ./cmd/server
|
||||
|
||||
# 双方言单测：sqlite 始终执行；postgres 需真实实例（FCB_TEST_PG_DSN 指向测试库）
|
||||
FCB_TEST_PG_DSN='postgres://postgres:postgres@localhost:5432/fcb_test?sslmode=disable' go test ./internal/database/ ./internal/settings/
|
||||
go test ./... # 全量单测（未设置 FCB_TEST_PG_DSN 时自动跳过 PG 用例）
|
||||
```
|
||||
|
||||
系统未初始化时除 `/setup` 与 `/api/v1/health` 外一律返回 428，初始化路由由 API 层任务接入。
|
||||
|
||||
## 开发注意
|
||||
|
||||
- **GOCACHE/GOMODCACHE 必须用 `export` 设置**（沙箱环境）：本地与 CI 沙箱通常禁止写默认 Go 缓存
|
||||
目录（`~/Library/Caches/go-build`）。注意一个隐蔽的坑——用**内联前缀变量**的方式
|
||||
（`GOCACHE=... GOMODCACHE=... go build ./... && go vet ./... && go test ./...`）时，
|
||||
只有第一条命令继承这些变量，`&&` 后续命令（vet/test）会丢失前缀、落回默认缓存路径，
|
||||
报错 `operation not permitted`（指向 `~/Library/Caches/...`）却极易误判为代码问题。
|
||||
正确写法：
|
||||
|
||||
```bash
|
||||
cd server
|
||||
export GOCACHE=$(pwd)/../.gocache GOMODCACHE=$(pwd)/../.gomodcache GOSUMDB=off
|
||||
go build ./... && go vet ./... && go test ./... # 后续命令也能继承 export 的变量
|
||||
```
