WeChat Article Fetcher (微信文章抓取)

Fetch WeChat (微信公众号) articles and convert to clean Markdown using Playwright browser automation.

Features

• Real Chromium browser to bypass WeChat anti-bot protections
• Automatic lazy-loaded image handling (data-src → src)
• Auto-generated filename from publish date + title (YYYYMMDD format)
• Metadata extraction (author, publish time)
• Clean Markdown output with preserved images

Dependencies

pip install playwright markdownify
playwright install chromium

Usage

# Auto-generate filename (YYYYMMDD+Title format)
python scripts/fetch_weixin.py "https://mp.weixin.qq.com/s/xxxxx"

# Custom filename
python scripts/fetch_weixin.py "https://mp.weixin.qq.com/s/xxxxx" article.md

Response Pattern

When user requests WeChat article fetching:

1. Validate URL: Ensure it's a WeChat URL (mp.weixin.qq.com)

2. Execute fetching:

   python scripts/fetch_weixin.py <url> [output_filename]
   

   Output filename is optional - auto-generates as YYYYMMDD+Title

3. Report results:

   • Confirm file saved with statistics (characters, words, images)
   • Show the auto-generated filename

Example Workflows

Auto-generated filename

# User: "抓取这篇微信文章"
python scripts/fetch_weixin.py "https://mp.weixin.qq.com/s/xxxxx"

# Result:
# ✓ Saved: 20251214关于财政政策和货币政策的关系.md
# ✓ Statistics: 12,345 characters, 8,234 words, 5 images

Custom filename

# User: "Fetch this WeChat article, save as economy.md"
python scripts/fetch_weixin.py "https://mp.weixin.qq.com/s/xxxxx" economy.md

# Result:
# ✓ Saved: economy.md

Troubleshooting

Issue	Solution
WeChat blocked	Script uses real browser to bypass anti-bot
Timeout	Script has 60s timeout with retry - usually succeeds on second attempt
Playwright not installed	Run: pip install playwright && playwright install chromium
Empty content	Wait for page to fully load; check if article is still accessible
Missing images	Script auto-converts lazy-loaded images; check network connectivity
