+# Lingma OpenAI Gateway
+
+把本地 Lingma 能力封装为 OpenAI 兼容接口，支持：
+
+- `GET /v1/models`
+- `POST /v1/chat/completions`
+- `stream=true`（SSE）
+- Bearer API Key 鉴权
+
+## 1. 准备目录
+
+```bash
+mkdir -p bin
+cp ../Lingma bin/Lingma
+chmod +x bin/Lingma
+```
+
+## 2. 配置环境变量
+
+```bash
+cp .env.example .env
+```
+
+至少修改：
+
+- `API_KEYS`
+- `LINGMA_USERNAME`
+- `LINGMA_PASSWORD`
+
+如果你的 Lingma 路径不同，修改：
+
+- `LINGMA_BIN`
+
+可选（企业专属域）：
+
+- `DEDICATED_DOMAIN_URL`
+
+### `.env` 字段说明（简版）
+
+- `HOST`：网关监听地址（通常 `0.0.0.0`）
+- `PORT`：网关监听端口（外部调用端口）
+- `API_KEYS`：Bearer Key，多个用逗号分隔
+- `LINGMA_BIN`：容器内 Lingma 路径
+- `LINGMA_WORK_DIR`：Lingma 工作目录（登录与会话数据）
+- `LINGMA_SOCKET_PORT`：Lingma 本地 WS 端口
+- `LINGMA_STARTUP_TIMEOUT`：Lingma 启动等待秒数
+- `LINGMA_RPC_TIMEOUT`：单次 RPC 超时秒数
+- `DEFAULT_MODEL`：默认模型（无法映射时兜底）
+- `DEFAULT_ASK_MODE`：默认模式（`chat`/`agent`）
+- `DEDICATED_DOMAIN_URL`：企业专属域（可留空）
+- `AUTO_LOGIN_ENABLED`：未登录时自动登录开关
+- `AUTO_LOGIN_HEADLESS`：自动登录是否无头浏览器
+- `AUTO_LOGIN_TIMEOUT`：自动登录超时秒数
+- `AUTO_LOGIN_MAX_RETRY`：自动登录重试次数
+- `LINGMA_USERNAME`：Lingma 登录用户名
+- `LINGMA_PASSWORD`：Lingma 登录密码
+
+### `.env` 最小必填示例
+
+```env
+PORT=8317
+API_KEYS=sk-your-api-key
+LINGMA_USERNAME=your-username
+LINGMA_PASSWORD=your-password
+DEDICATED_DOMAIN_URL=
+```
+
+## 3. Docker 运行
+
+```bash
+docker compose up -d --build
+```
+
+查看日志：
+
+```bash
+docker compose logs -f
+```
+
+## 4. 调用示例
+
+### 模型列表
+
+```bash
+curl -s http://127.0.0.1:8317/v1/models \
+  -H "Authorization: Bearer sk-your-api-key"
+```
+
+说明：
+
+- `id` 保持 Lingma 原始模型 key（兼容 OpenAI 客户端）
+- `name` 提供可读名称（如 `qwen3.6-plus`）
+- 调用 `/v1/chat/completions` 时，`model` 既可传 `id`，也可直接传 `name`
+
+### 非流式聊天
+
+```bash
+curl -s http://127.0.0.1:8317/v1/chat/completions \
+  -H "Authorization: Bearer sk-your-api-key" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "dashscope_qmodel",
+    "messages": [
+      {"role": "user", "content": "写一个 python hello world"}
+    ]
+  }'
+```
+
+### 流式聊天
+
+```bash
+curl -N http://127.0.0.1:8317/v1/chat/completions \
+  -H "Authorization: Bearer sk-your-api-key" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "dashscope_qmodel",
+    "stream": true,
+    "messages": [
+      {"role": "user", "content": "介绍一下你自己"}
+    ]
+  }'
+```
+
+## 5. 统计与监控
+
+支持调用次数与 token（估算值）统计：
+
+- `GET /internal/stats`（需 Bearer）
+- `GET /metrics`（Prometheus 文本格式）
+
+示例：
+
+```bash
+curl -s http://127.0.0.1:8317/internal/stats \
+  -H "Authorization: Bearer sk-xxx"
+```
+
+```bash
+curl -s http://127.0.0.1:8317/metrics
+```
+
+说明：
+
+- `usage.prompt_tokens/completion_tokens` 为估算值（按字节近似换算）。
+- 非流式响应里会附带 `usage` 字段。
+
+## 6. 容器内自动登录
+
+已内置自动登录能力（Playwright + Chromium）。
+
+你可以主动触发：
+
+```bash
+curl -s -X POST http://127.0.0.1:8317/internal/auto-login/start \
+  -H "Authorization: Bearer sk-your-api-key"
+```
+
+查看状态：
+
+```bash
+curl -s http://127.0.0.1:8317/internal/auto-login/status \
+  -H "Authorization: Bearer sk-your-api-key"
+```
+
+说明：
+
+- 若未登录，`/v1/models` 与 `/v1/chat/completions` 也会尝试自动登录。
+- 账号密码来自 `.env`（`LINGMA_USERNAME` / `LINGMA_PASSWORD`）。
+- 建议仅在受控环境使用，并妥善保护 `.env`。
+
+## 7. agent 模式
+
+在 v1 中，若 `model` 传 `agent` 或 `lingma-agent`，会走 agent 模式。
+
+```bash
+curl -s http://127.0.0.1:8317/v1/chat/completions \
+  -H "Authorization: Bearer sk-xxx" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "agent",
+    "messages": [
+      {"role": "user", "content": "分析这个项目目录结构"}
+    ]
+  }'
+```
