# QQ Bot

Connect Hermes to QQ via the **Official QQ Bot API (v2)** — supporting private (C2C), group @-mentions, guild, and direct messages with voice transcription.

## Overview

The QQ Bot adapter uses the [Official QQ Bot API](https://bot.q.qq.com/wiki/develop/api-v2/) to:

- Receive messages via a persistent **WebSocket** connection to the QQ Gateway
- Send text and markdown replies via the **REST API**
- Download and process images, voice messages, and file attachments
- Transcribe voice messages using Tencent's built-in ASR or a configurable STT provider

## Prerequisites

1. **QQ Bot Application** — Register at [q.qq.com](https://q.qq.com):
   - Create a new application and note your **App ID** and **App Secret**
   - Enable the required intents: C2C messages, Group @-messages, Guild messages
   - Configure your bot in sandbox mode for testing, or publish for production

2. **Dependencies** — The adapter requires `aiohttp` and `httpx`:
   ```bash
   pip install aiohttp httpx
   ```

## Configuration

### Interactive setup

```bash
hermes setup gateway
```

Select **QQ Bot** from the platform list and follow the prompts.

### Manual configuration

Set the required environment variables in `~/.hermes/.env`:

```bash
QQ_APP_ID=your-app-id
QQ_CLIENT_SECRET=your-app-secret
```

## Environment Variables

| Variable | Description | Default |
|---|---|---|
| `QQ_APP_ID` | QQ Bot App ID (required) | — |
| `QQ_CLIENT_SECRET` | QQ Bot App Secret (required) | — |
| `QQ_HOME_CHANNEL` | OpenID for cron/notification delivery | — |
| `QQ_HOME_CHANNEL_NAME` | Display name for home channel | `Home` |
| `QQ_ALLOWED_USERS` | Comma-separated user OpenIDs for DM access | open (all users) |
| `QQ_ALLOW_ALL_USERS` | Set to `true` to allow all DMs | `false` |
| `QQ_MARKDOWN_SUPPORT` | Enable QQ markdown (msg_type 2) | `true` |
| `QQ_STT_API_KEY` | API key for voice-to-text provider | — |
| `QQ_STT_BASE_URL` | Base URL for STT provider | `https://open.bigmodel.cn/api/coding/paas/v4` |
| `QQ_STT_MODEL` | STT model name | `glm-asr` |

## Advanced Configuration

For fine-grained control, add platform settings to `~/.hermes/config.yaml`:

```yaml
platforms:
  qq:
    enabled: true
    extra:
      app_id: "your-app-id"
      client_secret: "your-secret"
      markdown_support: true
      dm_policy: "open"          # open | allowlist | disabled
      allow_from:
        - "user_openid_1"
      group_policy: "open"       # open | allowlist | disabled
      group_allow_from:
        - "group_openid_1"
      stt:
        provider: "zai"          # zai (GLM-ASR), openai (Whisper), etc.
        baseUrl: "https://open.bigmodel.cn/api/coding/paas/v4"
        apiKey: "your-stt-key"
        model: "glm-asr"
```

## Voice Messages (STT)

Voice transcription works in two stages:

1. **QQ built-in ASR** (free, always tried first) — QQ provides `asr_refer_text` in voice message attachments, which uses Tencent's own speech recognition
2. **Configured STT provider** (fallback) — If QQ's ASR doesn't return text, the adapter calls an OpenAI-compatible STT API:

   - **Zhipu/GLM (zai)**: Default provider, uses `glm-asr` model
   - **OpenAI Whisper**: Set `QQ_STT_BASE_URL` and `QQ_STT_MODEL`
   - Any OpenAI-compatible STT endpoint

## Troubleshooting

### Bot disconnects immediately (quick disconnect)

This usually means:
- **Invalid App ID / Secret** — Double-check your credentials at q.qq.com
- **Missing permissions** — Ensure the bot has the required intents enabled
- **Sandbox-only bot** — If the bot is in sandbox mode, it can only receive messages from QQ's sandbox test channel

### Voice messages not transcribed

1. Check if QQ's built-in `asr_refer_text` is present in the attachment data
2. If using a custom STT provider, verify `QQ_STT_API_KEY` is set correctly
3. Check gateway logs for STT error messages

### Messages not delivered

- Verify the bot's **intents** are enabled at q.qq.com
- Check `QQ_ALLOWED_USERS` if DM access is restricted
- For group messages, ensure the bot is **@mentioned** (group policy may require allowlisting)
- Check `QQ_HOME_CHANNEL` for cron/notification delivery

### Connection errors

- Ensure `aiohttp` and `httpx` are installed: `pip install aiohttp httpx`
- Check network connectivity to `api.sgroup.qq.com` and the WebSocket gateway
- Review gateway logs for detailed error messages and reconnect behavior
