# Lingma OpenAI Gateway

将 Lingma 封装为 OpenAI / Anthropic 兼容网关，便于现有客户端直接接入。

- OpenAI：`/v1/models`、`/v1/chat/completions`（含 stream）
- Anthropic：`/v1/messages`、`/v1/messages/count_tokens`（含 stream）
- 内置：多实例池、会话复用、Prometheus 指标、登录态 bundle 注入
- 多模态降级：OpenAI `image_url` / `input_image` 转 `[image]`，`input_audio` 转 `[audio]`；Anthropic `image` 转 `[image]`

> 架构设计与二开细节请看 [`DESIGN.md`](./DESIGN.md)。

## 5 分钟启动

### 1) 准备配置

```bash
git clone <repo>
cd lingma-openai-gateway
cp .env.example .env
```

至少配置这些变量（在 `.env`）：

- `API_KEYS`
- `LINGMA_USERNAME` / `LINGMA_PASSWORD`（或 `LINGMA_SESSION_BUNDLE(_FILE)`）

### 2) Docker 启动（推荐）

```bash
mkdir -p data secrets
docker compose up -d --build
docker compose logs -f
```

### 3) 冒烟检查

```bash
PORT=$(grep '^PORT=' .env | cut -d= -f2)
API_KEY=$(grep '^API_KEYS=' .env | cut -d= -f2 | cut -d, -f1)

curl -s "http://127.0.0.1:${PORT}/healthz"
curl -s "http://127.0.0.1:${PORT}/v1/models" \
  -H "Authorization: Bearer ${API_KEY}"
```

---

## 常用命令

### 本地开发运行

```bash
pip install -r requirements.txt
uvicorn app.main:app --reload --port 8317
```

### Docker 常用

```bash
docker compose up -d --build
docker compose logs -f
docker compose ps
docker compose down
```

### 测试

```bash
# 重点回归套件
python3 -m unittest tests/test_tool_call_bridge.py

# 全量 unittest
python3 -m unittest discover -s tests -p "test_*.py"
```

---

## 最小 API 示例

先取 key：

```bash
PORT=$(grep '^PORT=' .env | cut -d= -f2)
API_KEY=$(grep '^API_KEYS=' .env | cut -d= -f2 | cut -d, -f1)
```

### OpenAI：非流式

```bash
curl -s "http://127.0.0.1:${PORT}/v1/chat/completions" \
  -H "Authorization: Bearer ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "org_auto",
    "messages": [{"role": "user", "content": "hi"}],
    "stream": false
  }'
```

### OpenAI：流式

```bash
curl -N "http://127.0.0.1:${PORT}/v1/chat/completions" \
  -H "Authorization: Bearer ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "org_auto",
    "messages": [{"role": "user", "content": "say hi"}],
    "stream": true
  }'
```

### Anthropic：非流式

```bash
curl -s "http://127.0.0.1:${PORT}/v1/messages" \
  -H "x-api-key: ${API_KEY}" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-3-5-sonnet-20241022",
    "max_tokens": 256,
    "messages": [{"role": "user", "content": "hi"}],
    "stream": false
  }'
```

### Anthropic：流式

```bash
curl -N "http://127.0.0.1:${PORT}/v1/messages" \
  -H "x-api-key: ${API_KEY}" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-3-5-sonnet-20241022",
    "max_tokens": 256,
    "messages": [{"role": "user", "content": "say hi"}],
    "stream": true
  }'
```

### Anthropic：count_tokens

```bash
curl -s "http://127.0.0.1:${PORT}/v1/messages/count_tokens" \
  -H "x-api-key: ${API_KEY}" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-3-5-sonnet-20241022",
    "max_tokens": 64,
    "messages": [{"role": "user", "content": "count me"}]
  }'
```

## 部署与更新

### 服务器更新到最新 main

```bash
cd /root/lingma-openai-gateway
git fetch origin
git checkout -B main origin/main
git reset --hard origin/main
git clean -fd
docker compose up -d --build
docker compose ps
```

### 健康检查

```bash
PORT=$(grep '^PORT=' .env | cut -d= -f2)
curl -s "http://127.0.0.1:${PORT}/healthz"
```

---

## 排障速查

| 现象 | 常见原因 | 处理 |
|---|---|---|
| `/v1/*` 返回 401 | 缺失或错误 API key | 检查 `Authorization: Bearer` 或 `x-api-key` |
| `healthz` 正常但请求失败 | 用错端口 | 以 `.env` 的 `PORT` 为准，`docker compose ps` 再确认 |
| `git pull` 提示 not on a branch | 处于 detached HEAD | 执行 `git checkout -B main origin/main` |
| 自动登录不稳定 | 浏览器流程波动 | 优先使用 `LINGMA_SESSION_BUNDLE(_FILE)` |
| 工具调用未触发 | 模型未选择工具 | 使用 `tool_choice` 强制，必要时约束输出 JSON |
