@zhin.js/adapter-onebot11

Zhin.js OneBot 11 adapter (Plugin Runtime). The production path is a forward WebSocket client (connection: ws); reverse WS is also supported (connection: wss, via httpHostToken).

Features

• OneBot 11 Standard compatible (events + actions)
• Convention-based defineAdapter / definePlugin (no usePlugin needed)
• Forward WebSocket (connection: ws): the application connects to the OneBot implementation's WS server
• access_token authentication (Bearer + query)
• Inbound via Endpoint.emit(...); outbound send({ conversation, payload })

Installation

pnpm add @zhin.js/adapter-onebot11

Plugin Runtime

• @zhin.js/adapter — convention-based adapters/onebot11.ts (defineAdapter)
• @zhin.js/core — Endpoint.emit(...) inbound, outboundMessageToken outbound
• zhin.js — plugin.ts (definePlugin)
• Configuration goes to plugins.<instanceKey> via the plugin's schema.json

Inbound: gateway.receive({ conversation, message, content, sender, metadata }) (kind: 'private'|'group') Outbound: send({ conversation, payload }) -> WS send_private_msg / send_group_msg (payload is rendered by gateway/core; no segment-mapper)

Prerequisites

1. Start a compatible OneBot 11 implementation and choose forward or reverse WebSocket.
2. Zhin must reach the implementation for forward WS; the implementation must reach Zhin for reverse WS.
3. Configure the same access_token on both sides and require authentication in production.

Minimal Configuration

# zhin.config.yml (Plugin Runtime)
plugins:
  onebot11:
    connection: ws
    reconnect_interval: 5000
    heartbeat_interval: 30000
    endpoints:
      - name: ob11-bot
        url: "ws://127.0.0.1:6700"
        access_token: "${ONEBOT11_ACCESS_TOKEN}"

The root plugin zhin.plugins (or project graph) must reference @zhin.js/adapter-onebot11 (instanceKey: onebot11).

Connection Modes

connection	Status
ws	Implemented (recommended)
wss	Implemented: reverse WS (httpHostToken)

Authentication

• Bearer: Authorization: Bearer <access_token>
• Forward WS attaches request headers during Upgrade and includes access_token in the URL query

Actions and Events

• Events: post_type (message/notice/request/meta_event), message_type, message, etc.
• Actions: send_private_msg, send_group_msg, delete_msg, set_group_special_title, etc.

AI Tools

Category	Path
Permit vocabulary	agent/PERMITS.md
Platform tools	agent/tools/set_title.ts -> onebot11_set_title
Skill documentation	agent/skills/onebot11.md

Migration Notes (Plugin Runtime)

• Notice / request / meta side events enter the unified Endpoint.emit(...) ingress and dispatch to handlers. Messages continue through outboundMessageToken.
• Group management tools have not been migrated yet: the old Adapter registered a full set of agent tools (kick/mute/group card, etc.) via createSceneManagementTools; after migration, only onebot11_set_title is retained. Other group management capabilities can be invoked via $client.call() (e.g., set_group_kick, set_group_ban) as an escape hatch.
• Platform permission access control: plugin.ts setup has registered registerDefaultScenePlatformPermitChecker('onebot11'). scene_admin / scene_owner are determined based on the sender's role (owner / admin) in the inbound metadata.

Troubleshooting

Symptom	Check
WS cannot connect	Direction, URL, port, and implementation WS service
401 or closed handshake	Matching Header/query token
Receives but cannot send	Send-action support and account risk controls
notice/request missing	Implementation post types and Endpoint request/notice views
