Overview

Package dingtalk implements an extractor for n.dingtalk.com / h5.dingtalk.com live replay shares, alidocs.dingtalk.com document previews, and shanji.dingtalk.com AI transcribe replays.

This extractor implements the full LWP (Lightweight Protocol) WebSocket client, ported from the decompiled Dingtalk_Live_Client.pyc source. LWP is a JSON-over-WebSocket RPC protocol connecting to wss://webalfa-cm3.dingtalk.com/long.

Supported URL types:

• Live replay: n.dingtalk.com/dingding/live-room/index.html?roomId=X&liveUuid=Y
• Public live share: h5.dingtalk.com/group-live-share/index.htm?encCid=X&liveUuid=Y
• AI transcribe: shanji.dingtalk.com/app/transcribes/<uuid>
• Document preview: alidocs.dingtalk.com/... (REST, no LWP needed)

Package dingtalk contains the LWP (Lightweight Protocol) WebSocket client for DingTalk live replay resolution.

LWP is a JSON-over-WebSocket RPC layer. The protocol is:

1. Connect to wss://webalfa-cm3.dingtalk.com/long
2. Send registration: {"lwp":"/reg","headers":{"app-key":"...","token":"<cookie-token>","ua":"...","mid":"0 0"}}
3. Receive registration ack with code 200
4. Make RPC calls: {"lwp":"<uri>","headers":{"mid":"<N> 0"},"body":[...]}
5. Match response by mid header

Ported from Dingtalk_Live_Client.pyc (LwpClient class, ~170 lines of core logic).
