QQ Bot (QQ机器人)

This guide covers setting up a Qwen Code channel on QQ via the official QQ Bot Open Platform API.

Prerequisites

• A QQ account (mobile app for scanning the QR code)

Setup

QR Code Login

Start the channel — the first time it will show a QR code. Scan it with your QQ app to activate. No developer account or manual registration needed. Credentials are saved and reused automatically.

{
  "channels": {
    "my-qq": {
      "type": "qq"
    }
  }
}

qwen channel start my-qq
# Scan the QR code in the terminal with your QQ app

Manual Configuration (Developer Portal)

You can also use credentials from the QQ Bot Open Platform  developer portal if you already have an app registered there:

{
  "channels": {
    "my-qq": {
      "type": "qq",
      "appID": "YOUR_APP_ID",
      "appSecret": "$QQ_APP_SECRET"
    }
  }
}

Set the secret as an environment variable:

export QQ_APP_SECRET=<your-app-secret>

Configuration

{
  "channels": {
    "my-qq": {
      "type": "qq",
      "appID": "YOUR_APP_ID",
      "appSecret": "$QQ_APP_SECRET",
      "sandbox": false,
      "privatePolicy": "open",
      "sessionScope": "thread",
      "cwd": "/path/to/your/project",
      "instructions": "你是一个通过 QQ Bot 对话的 AI 助手。回复控制在 2000 字符以内。",
      "groupPolicy": "disabled",
      "groups": {
        "*": { "requireMention": true }
      }
    }
  }
}

sessionScope defaults to "thread". With groupPolicy: "disabled" this is a DM-only setup, where both "thread" and "user" give each direct message its own context. "thread" is shown here for consistency with the Session Isolation section below — read that section’s upgrade note before changing the scope on an existing channel.

QQ-Specific Options

All standard channel options (see Channel Overview) are also supported: privatePolicy, allowedUsers, sessionScope, cwd, instructions, groupPolicy, groups, dispatchMode.

Running

# Start only the QQ channel
qwen channel start my-qq
 
# Or start all configured channels together
qwen channel start

Open QQ and send a message to your bot. You should see the response arrive in your chat.

Group Chats

To use the bot in QQ groups:

1. Set groupPolicy to "allowlist", "pairing", or "open" in your channel config
2. Add the bot to a QQ group via the QQ Bot Open Platform dashboard or by having a group admin invite it
3. Group members must @mention the bot to trigger a response
4. If using groupPolicy: "pairing", approve the group’s pairing request once before responses start. Note that once a group is approved, any member of that group can use the bot by default (restrict with the group’s senders: "allowlist" and allowedUsers); privatePolicy and the top-level allowedUsers do not gate members of an approved group.

QQ Bot API V2 only delivers group messages that @mention the bot — the bot does not see all group messages. By default, requireMention is true and should be left that way for QQ.

Session Isolation

The QQ channel defaults to sessionScope: "thread": members of the same group share a single conversation context keyed by <channel>:<group_openid>, while different groups are isolated from each other. Each direct message gets its own context keyed by <channel>:<user_openid>.

A group thread session is a shared session: every member of the group reads and continues the same conversation history. Commands that operate on that session (/clear, /cancel, /who, /status, /loop, /btw), permission answers (/approve, /approve-always, /deny), and steering an in-flight turn (a member’s plain message queues behind the running turn instead of steering it) are restricted to the members listed in the channel’s operators; allowedUsers and senderPolicy do not grant them. operators is unset by default, so out of the box a shared group session has no member authorized to run those commands — and a permission request raised in a group has no one who can answer it. Set operators to the QQ ids of the members who should be able to steer the group’s session. For a group message the gate compares against that member’s member_openid — the same id space as the group-scoped allowedUsers above — not the direct-message user_openid; a list filled with user_openids matches nobody, and because the list is non-empty the startup warning stays silent, so every command above is simply refused. A single- or chat_thread-scope channel is affected the same way, because those scopes share direct-message sessions too. The ! host-shell prefix is disabled in every QQ group chat, regardless of scope; in a direct message the same scope rule decides it — ! runs only where the scope keeps the session private to one sender ("thread" or "user"), and is refused for a DM too under "single" or "chat_thread" and for every group message. If group members should not share history or control each other’s turns, set sessionScope: "user" (each member gets a private session — see the upgrade note below before switching an existing channel), or restrict who can talk to the bot with the group-scoped senders / allowedUsers control — for example groups: {"*": {"senders": "allowlist", "allowedUsers": ["<member_openid>"]}}. The top-level senderPolicy, allowedUsers and privatePolicy govern direct messages only; they do not gate members of an approved group.

For full-message mode this default is already what you want — with groupAllPolicy: "all", keeping "thread" gives you shared context within a group and isolation across groups. If you instead set sessionScope: "user", full-message traffic is fragmented per sender (a separate session for every member), which is not suitable for group full-message scenarios.

The other shared scopes are not equivalents. sessionScope: "chat_thread" routes group messages exactly like "thread" (QQ supplies no thread id, so both key on <channel>:<chatId>), but it is treated as shared for every chat: each direct message becomes a shared session subject to the operators gate, so /clear in a DM is refused and a tool call raised in a DM has no one to answer it. sessionScope: "single" also shares direct messages, and additionally keys every group and every direct message to the one context <channel>:__single__, so group A’s history is answered with group B’s and with DM history — the cross-group leakage this section is about. The channel warns at startup whenever groupAllPolicy is "keyword" or "all" and the scope is not "thread". With multiSession enabled the scope is pinned to "user", so that warning names the two settings as mutually exclusive and tells the operator to change groupAllPolicy or turn multiSession off, instead of advising "thread".

Upgrading from an older QQ channel. The default scope changed from "user" to "thread". (A channel configured with groupAllPolicy: "keyword" or "all" was previously forced to "single" — one global session. A channel that did not pin sessionScope now resolves to "thread" unless multiSession is on, which resolves to "user" — per-sender sessions are the only shape multiSession supports, so it wins over the plugin default; for a channel without multiSession the effective change is from that global session to a per-group one. A channel that pinned sessionScope explicitly is no longer overridden, so an explicit "user" now takes effect and fragments group full-message traffic per sender — change it to "thread" by hand.) Legacy session routes are not deleted automatically: while purgeLegacySessions is off, each start counts the routes the purge covers — the single-scope-era <channel>:__single__ key and this channel’s legacy user-scope <channel>:<senderId>:<chatId> keys — and leaves them, and their daemon-side sessions, untouched. A chat_thread-era <channel>:<chatId>:<threadId> route is not covered: it is neither counted nor purged. To remove the covered routes, set purgeLegacySessions to true on the channel. With it enabled, every such route is released and its daemon-side session discarded, so the old conversation mappings stop existing; the purge runs on each start while the option stays on. Nothing is deleted unless the rescue copy reaches disk: immediately before the first deletion the channel appends the doomed routes to <channel>-sessions-purged.json in the channel state directory (for example ~/.qwen/channels/my-qq-sessions-purged.json; characters outside A-Za-z0-9_- in the channel name become _) and if that write fails it deletes nothing and leaves the routes in place. The file is written only when a deletion actually happens — never on a start that leaves everything alone. It is a JSON list of purge records, each with its purgedAt timestamp, sessionScope, and routes; each route carries its kind, key, sessionId, target, and — when the router’s persisted session state still records them — cwd, turns, startedAt, isolation, and workspaceCwd. Records are appended rather than overwritten, so an earlier purge’s record survives a later one (the oldest records are dropped once the list passes 20); a file that cannot be read, or does not hold a purge-record list, is reported in the log and renamed to a sibling <path>.corrupt-<timestamp> file before the new record is written, so the damaged copy is kept for hand recovery and the new record is never lost. That is routing metadata only — no conversation content — so it shows you what was dropped and lets you re-create the mapping by hand: a route whose record includes cwd and no isolation resolves to that same workspace when restored; when the record also carries isolation: "worktree", cwd is the (usually already removed) per-session worktree, so restore against the record’s workspaceCwd and keep isolation so the router re-attaches it through the managed load path. When the stored state for a route has no cwd (the entry is missing, or predates the field), the record simply omits cwd rather than guessing, so restoring such a route by hand also needs the channel’s workspace path. Setting sessionScope: "user" after a purge does not bring the old conversations back by itself — those routes are already gone and are not restored automatically.

See Group Chats for full details on group policies and mention gating.

Markdown Support

The QQ Bot channel supports Markdown formatting (msg_type=2). The agent’s Markdown responses are sent as-is, and QQ renders them with rich formatting (bold, italic, code blocks, links, lists).

If the QQ server rejects a Markdown message for any reason, the channel automatically retries it as plain text — so your messages always go through even if the bot’s Markdown capability is restricted server-side.

This is the opposite of the WeChat channel, which strips all Markdown. You can let the agent use full Markdown with the QQ channel.

Images, Videos, and Files

Users can send images, videos, files, and voice messages to the bot. An image is passed to the agent as vision input, so the agent sees the picture itself — screenshots, error messages, and diagrams all work — and the same file is also saved to a temporary local path for the case where the model cannot take images. A video, a file, or a voice message is saved to a temporary local path and the agent is told that path.

A media message does not need any text — an image-only, video-only, file-only, or voice-only message starts a turn, and the channel uses (image), (video), (file), or (voice) as the placeholder. When the message does carry text, that text is kept as the caption.

A file is anything the platform delivers as content_type: file — Word documents, PDFs, spreadsheets, archives, source files. QQ reports no MIME type for a file, so the channel keeps the sender’s own extension (restricted to letters and digits, falling back to .bin when there is none) and saves the bytes under channel-files/<uuid>/ in the system temporary directory; the agent’s read tool uses that extension to decide how to open the document.

A voice message arrives as content_type: voice. Alongside the original SILK URL, QQ provides voice_wav_url — the same audio already converted to WAV — and the channel prefers it; when the platform does not send one, the channel falls back to the original URL. The bytes are saved under channel-files/<uuid>/ as qq_voice.wav, or qq_voice.silk when the original SILK URL was used, and the agent is told that path. The platform’s ASR text is not used; the agent works from the saved audio file.

• Images are limited to 8 MB and videos, files, and voice messages to 20 MB, and at most five attachments per message are handled. Anything larger is skipped and logged to the channel’s stderr.
• Downloaded files are not deleted. They stay under the system temporary directory, which the system clears on its own schedule.

Image input requires a model that accepts images. Declare the capability when the model is multimodal but not recognised by name. The field belongs on the provider entry that serves the model, because a top-level model.generationConfig value is ignored for provider-backed models:

{
  "modelProviders": {
    "openai": [
      {
        "id": "your-model-id",
        "baseUrl": "https://example.invalid/v1",
        "generationConfig": {
          "modalities": { "image": true }
        }
      }
    ]
  }
}

With a text-only model the agent receives an “unsupported image” note plus the saved path instead of the picture.

Sending images, videos, files, or voice messages back to QQ is not supported.

Token Management

Access tokens expire after approximately 2 hours. The channel automatically refreshes them at 80% of their TTL (typically ~1.6 hours). If a refresh fails, it retries after 60 seconds.

Token refresh continues across WebSocket reconnects — the channel never goes offline due to an expired token as long as the AppID and AppSecret remain valid.

Connection Resilience

• Auto-reconnect: On WebSocket disconnect, the channel retries with exponential backoff (up to 20 attempts, max 30 seconds between retries)
• Session resume: If the WebSocket drops briefly, the channel uses QQ’s RESUME opcode to restore the session without losing in-flight messages
• Cross-server context continuation: Chat sessions and routing state are persisted to disk. If the daemon restarts, conversations continue from where they left off
• Heartbeat monitoring: HEARTBEAT_ACK timeouts are detected and force a reconnection to avoid zombie connections
• Message deduplication: Replayed messages after a reconnect are detected and skipped

Tips

• Use Markdown freely — Unlike WeChat, QQ renders Markdown natively. Bold, code blocks, lists, and links all work.
• Keep responses under 2000 characters — Longer responses are automatically split into chunks. Adding a length hint to your instructions helps the agent stay concise.
• Sandbox for testing — Set "sandbox": true to use the sandbox API during development. No production messages will be affected.
• Restrict access — Use privatePolicy: "allowlist" for a fixed set of QQ users, or "pairing" to approve new users from the CLI. See DM Pairing for details.

Key Differences from Telegram

Troubleshooting

Bot doesn’t respond

• Check the terminal output for errors
• Verify the channel is running (qwen channel status)
• If using privatePolicy: "allowlist", make sure your QQ user ID is in allowedUsers
• On first start, a QR code will appear in the terminal — scan it with your QQ app

Bot doesn’t respond in groups

• Check that groupPolicy is set to "allowlist", "pairing", or "open" (default is "disabled")
• If using "pairing", verify the group’s pairing request has been approved
• You must @mention the bot — QQ only delivers messages that tag the bot
• Verify the bot has been added to the group

QR code login is stuck

• The QR code is displayed in the terminal. Scan it with your QQ mobile app (Me → Scan)
• If the QR code expires (typically after a few minutes), restart the channel to get a new one

Markdown messages appear as plain text

• The QQ server may have rejected the Markdown message and the channel silently fell back to plain text. Check the terminal for "Markdown rejected" log messages
• This is unusual on the QQ Bot Open Platform but can happen if the bot’s Markdown capability is restricted server-side

Token expired after long downtime

• If the channel is offline for more than 2 hours, the access token will have expired. The channel fetches a fresh token on reconnect — no action needed
• If the AppSecret itself is invalid (e.g., rotated in the developer portal), update the appSecret field or delete ~/.qwen/channels/<name>-credentials.json to re-trigger QR code login
