Info-Spider - 微信公众号爬虫 CLI

A CLI crawler for WeChat Official Account (公众号) articles via the MP backend.

Architecture

• Crate location: crates/info-spider/
• Auth flow: WeChat QR code login (completely separate from IAAA, does NOT use info-common)
• API: mp.weixin.qq.com backend API
• Config: ~/.config/info-spider/ (separate from info-common Store)
• Flow docs: docs/wechat-mp-flow.md

Key Source Files

• src/main.rs — Entry point
• src/cli.rs — Clap CLI definition
• src/commands.rs — Command implementations
• src/api.rs — WeChat MP API client
• src/session.rs — Own session persistence (token, fingerprint, bizuin)
• src/client.rs — reqwest client builders

CLI Commands

Command	Function
login	WeChat QR code scan login to mp.weixin.qq.com
logout / status	Session management
search <QUERY>	Find Official Accounts by name/ID (returns fakeid list)
articles	Fetch articles from an OA (--name or --fakeid)
scrape <URL>	Convert single article URL to Markdown

Articles Command Options

• --begin — Start offset for pagination
• --count — Articles per page
• --limit — Maximum total articles to fetch
• --delay-ms — Random delay between requests (anti-crawler)
• --format {table|json|jsonl} — Output format

Development Notes

• Standalone auth: Uses its own WeChat QR login, NOT the IAAA flow from info-common
• Own session.rs: Stores token, fingerprint, bizuin (different from info-common session format)
• Mimics real user behavior with configurable delays to bypass risk controls
• Article scraping extracts content to clean Markdown
• Multiple output formats: table (default), JSON, JSONL
• All user-facing strings in Chinese
• Error handling: anyhow::Result with .context("中文描述")
