# 720 云资源提取脚本
|
||||
|
||||
本目录为 Python 脚本，用于从 720yun 页面或保存的 HTML 中提取并下载全景图资源。**请在项目根目录下执行**，脚本会自动读写根目录下的 `text.md`、`image/`、`panorama/`、`config.json` 等。
|
||||
|
||||
## 脚本说明
|
||||
|
||||
| 脚本 | 用途 |
|
||||
|------|------|
|
||||
| **fetch_720yun.py** | 根据 720yun 页面 URL 抓取 HTML，解析其中的全景图 URL 并下载到 `panorama/panorama.jpg`，同时更新根目录 `config.json`。适用于页面内直接包含图片链接的情况。 |
|
||||
| **parse_720yun_doc.py** | 从项目根目录的 `text.md`（720yun 页面另存为的文档）解析 `window.data` / `window.json`，得到六面图、缩略图等 URL；可选 `--fetch` 请求场景 JSON，`--download` 将六面图 + 缩略图下载到根目录 `image/`。 |
|
||||
|
||||
## 使用示例
|
||||
|
||||
```bash
|
||||
# 在项目根目录 720yun-offline/ 下执行
|
||||
|
||||
# 方式一：按 URL 抓取（若页面由 JS 动态加载可能无结果）
|
||||
python3 scripts/fetch_720yun.py "https://www.720yun.com/vr/xxxxx"
|
||||
|
||||
# 方式二：先浏览器打开 720 链接，整页另存为 text.md 放到项目根目录，再解析并下载六面图
|
||||
python3 scripts/parse_720yun_doc.py # 仅解析，输出 parsed_720yun_resources.json
|
||||
python3 scripts/parse_720yun_doc.py --fetch # 解析并请求场景 JSON
|
||||
python3 scripts/parse_720yun_doc.py --download # 解析并将六面图、缩略图下载到 image/
|
||||
```
|
||||
|
||||
下载到 `image/` 的文件可直接被前端使用（`config.json` 中已配置 `image/mobile_*.jpg`）。
