+# 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 ./...
+```
