+# sub2api 项目开发指南
+
+> 本文档记录项目环境配置、常见坑点和注意事项，供 Claude Code 和团队成员参考。
+
+## 一、项目基本信息
+
+| 项目 | 说明 |
+|------|------|
+| **上游仓库** | Wei-Shaw/sub2api |
+| **Fork 仓库** | bayma888/sub2api-bmai |
+| **技术栈** | Go 后端 (Ent ORM + Gin) + Vue3 前端 (pnpm) |
+| **数据库** | PostgreSQL 16 + Redis |
+| **包管理** | 后端: go modules, 前端: **pnpm**（不是 npm） |
+
+## 二、本地环境配置
+
+### PostgreSQL 16 (Windows 服务)
+
+| 配置项 | 值 |
+|--------|-----|
+| 端口 | 5432 |
+| psql 路径 | `C:\Program Files\PostgreSQL\16\bin\psql.exe` |
+| pg_hba.conf | `C:\Program Files\PostgreSQL\16\data\pg_hba.conf` |
+| 数据库凭据 | user=`sub2api`, password=`sub2api`, dbname=`sub2api` |
+| 超级用户 | user=`postgres`, password=`postgres` |
+
+### Redis
+
+| 配置项 | 值 |
+|--------|-----|
+| 端口 | 6379 |
+| 密码 | 无 |
+
+### 开发工具
+
+```bash
+# golangci-lint v2.7
+go install github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.7
+
+# pnpm (前端包管理)
+npm install -g pnpm
+```
+
+## 三、CI/CD 流水线
+
+### GitHub Actions Workflows
+
+| Workflow | 触发条件 | 检查内容 |
+|----------|----------|----------|
+| **backend-ci.yml** | push, pull_request | 单元测试 + 集成测试 + golangci-lint v2.7 |
+| **security-scan.yml** | push, pull_request, 每周一 | govulncheck + gosec + pnpm audit |
+| **release.yml** | tag `v*` | 构建发布（PR 不触发） |
+
+### CI 要求
+
+- Go 版本必须是 **1.25.7**
+- 前端使用 `pnpm install --frozen-lockfile`，必须提交 `pnpm-lock.yaml`
+
+### 本地测试命令
+
+```bash
+# 后端单元测试
+cd backend && go test -tags=unit ./...
+
+# 后端集成测试
+cd backend && go test -tags=integration ./...
+
+# 代码质量检查
+cd backend && golangci-lint run ./...
+
+# 前端依赖安装（必须用 pnpm）
+cd frontend && pnpm install
+```
+
+## 四、常见坑点 & 解决方案
+
+### 坑 1：pnpm-lock.yaml 必须同步提交
+
+**问题**：`package.json` 新增依赖后，CI 的 `pnpm install --frozen-lockfile` 失败。
+
+**原因**：上游 CI 使用 pnpm，lock 文件不同步会报错。
+
+**解决**：
+```bash
+cd frontend
+pnpm install  # 更新 pnpm-lock.yaml
+git add pnpm-lock.yaml
+git commit -m "chore: update pnpm-lock.yaml"
+```
+
+---
+
+### 坑 2：npm 和 pnpm 的 node_modules 冲突
+
+**问题**：之前用 npm 装过 `node_modules`，pnpm install 报 `EPERM` 错误。
+
+**解决**：
+```bash
+cd frontend
+rm -rf node_modules  # 或 PowerShell: Remove-Item -Recurse -Force node_modules
+pnpm install
+```
+
+---
+
+### 坑 3：PowerShell 中 bcrypt hash 的 `$` 被转义
+
+**问题**：bcrypt hash 格式如 `$2a$10$xxx...`，PowerShell 把 `$2a` 当变量解析，导致数据丢失。
+
+**解决**：将 SQL 写入文件，用 `psql -f` 执行：
+```bash
+# 错误示范（PowerShell 会吃掉 $）
+psql -c "INSERT INTO users ... VALUES ('$2a$10$...')"
+
+# 正确做法
+echo "INSERT INTO users ... VALUES ('\$2a\$10\$...')" > temp.sql
+psql -U sub2api -h 127.0.0.1 -d sub2api -f temp.sql
+```
+
+---
+
+### 坑 4：psql 不支持中文路径
+
+**问题**：`psql -f "D:\中文路径\file.sql"` 报错找不到文件。
+
+**解决**：复制到纯英文路径再执行：
+```bash
+cp "D:\中文路径\file.sql" "C:\temp.sql"
+psql -f "C:\temp.sql"
+```
+
+---
+
+### 坑 5：PostgreSQL 密码重置流程
+
+**场景**：忘记 PostgreSQL 密码。
+
+**步骤**：
+1. 修改 `C:\Program Files\PostgreSQL\16\data\pg_hba.conf`
+   ```
+   # 将 scram-sha-256 改为 trust
+   host    all    all    127.0.0.1/32    trust
+   ```
+2. 重启 PostgreSQL 服务
+   ```powershell
+   Restart-Service postgresql-x64-16
+   ```
+3. 无密码登录并重置
+   ```bash
+   psql -U postgres -h 127.0.0.1
+   ALTER USER sub2api WITH PASSWORD 'sub2api';
+   ALTER USER postgres WITH PASSWORD 'postgres';
+   ```
+4. 改回 `scram-sha-256` 并重启
+
+---
+
+### 坑 6：Go interface 新增方法后 test stub 必须补全
+
+**问题**：给 interface 新增方法后，编译报错 `does not implement interface (missing method XXX)`。
+
+**原因**：所有测试文件中实现该 interface 的 stub/mock 都必须补上新方法。
+
+**解决**：
+```bash
+# 搜索所有实现该 interface 的 struct
+cd backend
+grep -r "type.*Stub.*struct" internal/
+grep -r "type.*Mock.*struct" internal/
+
+# 逐一补全新方法
+```
+
+---
+
+### 坑 7：Windows 上 psql 连 localhost 的 IPv6 问题
+
+**问题**：psql 连 `localhost` 先尝试 IPv6 (::1)，可能报错后再回退 IPv4。
+
+**建议**：直接用 `127.0.0.1` 代替 `localhost`。
+
+---
+
+### 坑 8：Windows 没有 make 命令
+
+**问题**：CI 里用 `make test-unit`，本地 Windows 没有 make。
+
+**解决**：直接用 Makefile 里的原始命令：
+```bash
+# 代替 make test-unit
+go test -tags=unit ./...
+
+# 代替 make test-integration
+go test -tags=integration ./...
+```
+
+---
+
+### 坑 9：Ent Schema 修改后必须重新生成
+
+**问题**：修改 `ent/schema/*.go` 后，代码不生效。
+
+**解决**：
+```bash
+cd backend
+go generate ./ent  # 重新生成 ent 代码
+git add ent/       # 生成的文件也要提交
+```
+
+---
+
+### 坑 10：PR 提交前检查清单
+
+提交 PR 前务必本地验证：
+
+- [ ] `go test -tags=unit ./...` 通过
+- [ ] `go test -tags=integration ./...` 通过
+- [ ] `golangci-lint run ./...` 无新增问题
+- [ ] `pnpm-lock.yaml` 已同步（如果改了 package.json）
+- [ ] 所有 test stub 补全新接口方法（如果改了 interface）
+- [ ] Ent 生成的代码已提交（如果改了 schema）
+
+## 五、常用命令速查
+
+### 数据库操作
+
+```bash
+# 连接数据库
+psql -U sub2api -h 127.0.0.1 -d sub2api
+
+# 查看所有用户
+psql -U postgres -h 127.0.0.1 -c "\du"
+
+# 查看所有数据库
+psql -U postgres -h 127.0.0.1 -c "\l"
+
+# 执行 SQL 文件
+psql -U sub2api -h 127.0.0.1 -d sub2api -f migration.sql
+```
+
+### Git 操作
+
+```bash
+# 同步上游
+git fetch upstream
+git checkout main
+git merge upstream/main
+git push origin main
+
+# 创建功能分支
+git checkout -b feature/xxx
+
+# Rebase 到最新 main
+git fetch upstream
+git rebase upstream/main
+```
+
+### 前端操作
+
+```bash
+# 安装依赖（必须用 pnpm）
+cd frontend
+pnpm install
+
+# 开发服务器
+pnpm dev
+
+# 构建
+pnpm build
+```
+
+### 后端操作
+
+```bash
+# 运行服务器
+cd backend
+go run ./cmd/server/
+
+# 生成 Ent 代码
+go generate ./ent
+
+# 运行测试
+go test -tags=unit ./...
+go test -tags=integration ./...
+
+# Lint 检查
+golangci-lint run ./...
+```

-#### Installation Steps
+#### Quick Start (One-Click Deployment)
+
+Use the automated deployment script for easy setup:
+
+```bash
+# Create deployment directory
+mkdir -p sub2api-deploy && cd sub2api-deploy
+
+# Download and run deployment preparation script
+curl -sSL https://raw.githubusercontent.com/Wei-Shaw/sub2api/main/deploy/docker-deploy.sh | bash
+
+# Start services
+docker-compose -f docker-compose.local.yml up -d
+
+# View logs
+docker-compose -f docker-compose.local.yml logs -f sub2api
+```
+
+**What the script does:**
+- Downloads `docker-compose.local.yml` and `.env.example`
+- Generates secure credentials (JWT_SECRET, TOTP_ENCRYPTION_KEY, POSTGRES_PASSWORD)
+- Creates `.env` file with auto-generated secrets
+- Creates data directories (uses local directories for easy backup/migration)
+- Displays generated credentials for your reference
+
+#### Manual Deployment
+
+If you prefer manual setup:
 
 ```bash
 # 1. Clone the repository
 git clone https://github.com/Wei-Shaw/sub2api.git
-cd sub2api
+cd sub2api/deploy
 
-# 2. Enter the deploy directory
-cd deploy
-
-# 3. Copy environment configuration
+# 2. Copy environment configuration
 cp .env.example .env
 
-# 4. Edit configuration (set your passwords)
+# 3. Edit configuration (generate secure passwords)
 nano .env
 ```
 
 **Required configuration in `.env`:**
 
 ```bash
-# PostgreSQL password (REQUIRED - change this!)
+# PostgreSQL password (REQUIRED)
 POSTGRES_PASSWORD=your_secure_password_here
 
+# JWT Secret (RECOMMENDED - keeps users logged in after restart)
+JWT_SECRET=your_jwt_secret_here
+
+# TOTP Encryption Key (RECOMMENDED - preserves 2FA after restart)
+TOTP_ENCRYPTION_KEY=your_totp_key_here
+
 # Optional: Admin account
 ADMIN_EMAIL=admin@example.com
 ADMIN_PASSWORD=your_admin_password
 
 # Optional: Custom port
 SERVER_PORT=8080
+```
 
-# Optional: Security configuration
-# Enable URL allowlist validation (false to skip allowlist checks, only basic format validation)
-SECURITY_URL_ALLOWLIST_ENABLED=false
+**Generate secure secrets:**
+```bash
+# Generate JWT_SECRET
+openssl rand -hex 32
 
-# Allow insecure HTTP URLs when allowlist is disabled (default: false, requires https)
-# ⚠️ WARNING: Enabling this allows HTTP (plaintext) URLs which can expose API keys
-#             Only recommended for:
-#             - Development/testing environments
-#             - Internal networks with trusted endpoints
-#             - When using local test servers (http://localhost)
-# PRODUCTION: Keep this false or use HTTPS URLs only
-SECURITY_URL_ALLOWLIST_ALLOW_INSECURE_HTTP=false
+# Generate TOTP_ENCRYPTION_KEY
+openssl rand -hex 32
 
-# Allow private IP addresses for upstream/pricing/CRS (for internal deployments)
-SECURITY_URL_ALLOWLIST_ALLOW_PRIVATE_HOSTS=false
+# Generate POSTGRES_PASSWORD
+openssl rand -hex 32
 ```
 
 ```bash
+# 4. Create data directories (for local version)
+mkdir -p data postgres_data redis_data
+
 # 5. Start all services
+# Option A: Local directory version (recommended - easy migration)
+docker-compose -f docker-compose.local.yml up -d
+
+# Option B: Named volumes version (simple setup)
 docker-compose up -d
 
 # 6. Check status
-docker-compose ps
+docker-compose -f docker-compose.local.yml ps
 
 # 7. View logs
-docker-compose logs -f sub2api
+docker-compose -f docker-compose.local.yml logs -f sub2api
 ```
 
+#### Deployment Versions
+
+| Version | Data Storage | Migration | Best For |
+|---------|-------------|-----------|----------|
+| **docker-compose.local.yml** | Local directories | ✅ Easy (tar entire directory) | Production, frequent backups |
+| **docker-compose.yml** | Named volumes | ⚠️ Requires docker commands | Simple setup |
+
+**Recommendation:** Use `docker-compose.local.yml` (deployed by script) for easier data management.
+
 #### Access
 
 Open `http://YOUR_SERVER_IP:8080` in your browser.
 
+If admin password was auto-generated, find it in logs:
+```bash
+docker-compose -f docker-compose.local.yml logs sub2api | grep "admin password"
+```
+
 #### Upgrade
 
 ```bash
 # Pull latest image and recreate container
-docker-compose pull
-docker-compose up -d
+docker-compose -f docker-compose.local.yml pull
+docker-compose -f docker-compose.local.yml up -d
+```
+
+#### Easy Migration (Local Directory Version)
+
+When using `docker-compose.local.yml`, migrate to a new server easily:
+
+```bash
+# On source server
+docker-compose -f docker-compose.local.yml down
+cd ..
+tar czf sub2api-complete.tar.gz sub2api-deploy/
+
+# Transfer to new server
+scp sub2api-complete.tar.gz user@new-server:/path/
+
+# On new server
+tar xzf sub2api-complete.tar.gz
+cd sub2api-deploy/
+docker-compose -f docker-compose.local.yml up -d
 ```
 
 #### Useful Commands
 
 ```bash
 # Stop all services
-docker-compose down
+docker-compose -f docker-compose.local.yml down
 
 # Restart
-docker-compose restart
+docker-compose -f docker-compose.local.yml restart
 
 # View all logs
-docker-compose logs -f
+docker-compose -f docker-compose.local.yml logs -f
+
+# Remove all data (caution!)
+docker-compose -f docker-compose.local.yml down
+rm -rf data/ postgres_data/ redis_data/
 ```

+
+# 选项 B：命名卷版（简单设置）
 docker-compose up -d
 
 # 6. 查看状态
-docker-compose ps
+docker-compose -f docker-compose.local.yml ps
 
 # 7. 查看日志
-docker-compose logs -f sub2api
+docker-compose -f docker-compose.local.yml logs -f sub2api
 ```
 
+#### 部署版本对比
+
+| 版本 | 数据存储 | 迁移便利性 | 适用场景 |
+|------|---------|-----------|---------|
+| **docker-compose.local.yml** | 本地目录 | ✅ 简单（打包整个目录） | 生产环境、频繁备份 |
+| **docker-compose.yml** | 命名卷 | ⚠️ 需要 docker 命令 | 简单设置 |
+
+**推荐：** 使用 `docker-compose.local.yml`（脚本部署）以便更轻松地管理数据。
+
 #### 访问
 
 在浏览器中打开 `http://你的服务器IP:8080`
 
+如果管理员密码是自动生成的，在日志中查找：
+```bash
+docker-compose -f docker-compose.local.yml logs sub2api | grep "admin password"
+```
+
 #### 升级
 
 ```bash
 # 拉取最新镜像并重建容器
-docker-compose pull
-docker-compose up -d
+docker-compose -f docker-compose.local.yml pull
+docker-compose -f docker-compose.local.yml up -d
+```
+
+#### 轻松迁移（本地目录版）
+
+使用 `docker-compose.local.yml` 时，可以轻松迁移到新服务器：
+
+```bash
+# 源服务器
+docker-compose -f docker-compose.local.yml down
+cd ..
+tar czf sub2api-complete.tar.gz sub2api-deploy/
+
+# 传输到新服务器
+scp sub2api-complete.tar.gz user@new-server:/path/
+
+# 新服务器
+tar xzf sub2api-complete.tar.gz
+cd sub2api-deploy/
+docker-compose -f docker-compose.local.yml up -d
 ```
 
 #### 常用命令
 
 ```bash
 # 停止所有服务
-docker-compose down
+docker-compose -f docker-compose.local.yml down
 
 # 重启
-docker-compose restart
+docker-compose -f docker-compose.local.yml restart
 
 # 查看所有日志
-docker-compose logs -f
+docker-compose -f docker-compose.local.yml logs -f
+
+# 删除所有数据（谨慎！）
+docker-compose -f docker-compose.local.yml down
+rm -rf data/ postgres_data/ redis_data/
 ```
