# Taoguba Crawler
This skill runs the Taoguba (tgb.cn) article crawlers located in the project root.
## Prerequisites
- Python 3 with `requests`, `beautifulsoup4`, `python-dotenv` installed
- A `.env` file in the project root containing `COOKIE` and optionally `USER_AGENT`
## Available Crawlers
### 1. BBS Crawler (`crawler_bbs.py`)
Crawl the forum board at `tgb.cn/bbs/1/1` using HTML scraping.
```bash
python crawler_bbs.py
```
- Extracts article list by parsing `a.overhide.mw300` elements
- Gets each article's main post and author replies
- Downloads images and embeds them as base64 in HTML
- Outputs: `output/bbs_YYYY-MM-DD.json` and `output/bbs_YYYY-MM-DD_HHMMSS.html`
### 2. Home Crawler (`crawler_home.py`)
Crawl the homepage recommendations via JSON API (`/newIndex/getZh`).
```bash
python crawler_home.py
```
- Fetches articles from the JSON API (default 2 pages)
- Same content extraction and HTML generation as BBS crawler
- Outputs: `output/home_YYYY-MM-DD.json` and `output/home_YYYY-MM-DD_HHMMSS.html`
## Common Workflow
To run both crawlers:
```bash
python crawler_bbs.py && python crawler_home.py
```
## Key Implementation Details
- **Authentication**: Both scripts read `COOKIE` from `.env` via `python-dotenv`
- **Rate limiting**: 0.5-1s delay between requests to avoid being blocked
- **Image handling**: Images are downloaded and embedded as base64 in the HTML output
- **Article content**: Extracts main post (`#first`) and author replies (`.comment-data` with author badge)
- **Output directory**: All results saved to `output/` folder
## Scripts
The crawler scripts are bundled in `scripts/`:
- **`scripts/crawler_bbs.py`** - BBS forum crawler (HTML scraping)
- **`scripts/crawler_home.py`** - Homepage crawler (JSON API)
To run the bundled scripts directly:
```bash
python scripts/crawler_bbs.py
python scripts/crawler_home.py
```
## Troubleshooting
- If no articles are returned, check that `.env` contains a valid `COOKIE` value
- If image downloads fail, the HTML will show error messages inline
- Network timeouts default to 10-15 seconds per request
