+# 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)

+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/

+- `turnstile.required` to require Turnstile in release mode
+
+**⚠️ Security Warning: HTTP URL Configuration**
+
+When `security.url_allowlist.enabled=false`, the system performs minimal URL validation by default, **rejecting HTTP URLs** and only allowing HTTPS. To allow HTTP URLs (e.g., for development or internal testing), you must explicitly set:
+
+```yaml
+security:
+  url_allowlist:
+    enabled: false                # Disable allowlist checks
+    allow_insecure_http: true     # Allow HTTP URLs (⚠️ INSECURE)

+
+**Or via environment variable:**
+
 ```bash
-# 7. Run the application
+SECURITY_URL_ALLOWLIST_ENABLED=false
+SECURITY_URL_ALLOWLIST_ALLOW_INSECURE_HTTP=true
+```
+
+**Risks of allowing HTTP:**
+- API keys and data transmitted in **plaintext** (vulnerable to interception)
+- Susceptible to **man-in-the-middle (MITM) attacks**
+- **NOT suitable for production** environments
+
+**When to use HTTP:**
+- ✅ Development/testing with local servers (http://localhost)
+- ✅ Internal networks with trusted endpoints
+- ✅ Testing account connectivity before obtaining HTTPS
+- ❌ Production environments (use HTTPS only)
+
+**Example error without this setting:**
+```
+Invalid base URL: invalid url scheme: http
+```
+
+If you disable URL validation or response header filtering, harden your network layer:
+- Enforce an egress allowlist for upstream domains/IPs
+- Block private/loopback/link-local ranges
+- Enforce TLS-only outbound traffic
+- Strip sensitive upstream response headers at the proxy

+## Antigravity Support
+
+Sub2API supports [Antigravity](https://antigravity.so/) accounts. After authorization, dedicated endpoints are available for Claude and Gemini models.
+
+### Dedicated Endpoints
+
+| Endpoint | Model |
+|----------|-------|
+| `/antigravity/v1/messages` | Claude models |
+| `/antigravity/v1beta/` | Gemini models |
+
+### Claude Code Configuration
+
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
+export ANTHROPIC_AUTH_TOKEN="sk-xxx"
+```
+
+### Hybrid Scheduling Mode
+
+Antigravity accounts support optional **hybrid scheduling**. When enabled, the general endpoints `/v1/messages` and `/v1beta/` will also route requests to Antigravity accounts.
+
+> **⚠️ Warning**: Anthropic Claude and Antigravity Claude **cannot be mixed within the same conversation context**. Use groups to isolate them properly.
+
+### Known Issues
+
+In Claude Code, Plan Mode cannot exit automatically. (Normally when using the native Claude API, after planning is complete, Claude Code will pop up options for users to approve or reject the plan.)
+
+**Workaround**: Press `Shift + Tab` to manually exit Plan Mode, then type your response to approve or reject the plan.

+## 简易模式
+
+简易模式适合个人开发者或内部团队快速使用，不依赖完整 SaaS 功能。
+
+- 启用方式：设置环境变量 `RUN_MODE=simple`
+- 功能差异：隐藏 SaaS 相关功能，跳过计费流程
+- 安全注意事项：生产环境需同时设置 `SIMPLE_MODE_CONFIRM=true` 才允许启动

+## Antigravity 使用说明
+
+Sub2API 支持 [Antigravity](https://antigravity.so/) 账户，授权后可通过专用端点访问 Claude 和 Gemini 模型。
+
+### 专用端点
+
+| 端点 | 模型 |
+|------|------|
+| `/antigravity/v1/messages` | Claude 模型 |
+| `/antigravity/v1beta/` | Gemini 模型 |
+
+### Claude Code 配置示例
+
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
+export ANTHROPIC_AUTH_TOKEN="sk-xxx"
+```
+
+### 混合调度模式
+
+Antigravity 账户支持可选的**混合调度**功能。开启后，通用端点 `/v1/messages` 和 `/v1beta/` 也会调度该账户。
+
+> **⚠️ 注意**：Anthropic Claude 和 Antigravity Claude **不能在同一上下文中混合使用**，请通过分组功能做好隔离。
+
+
+### 已知问题
+在 Claude Code 中，无法自动退出Plan Mode。（正常使用原生Claude Api时，Plan 完成后，Claude Code会弹出弹出选项让用户同意或拒绝Plan。） 
+解决办法：shift + Tab，手动退出Plan mode，然后输入内容 告诉 Claude Code 同意或拒绝 Plan
