## 使用方法
### 1. 请求下载
```bash
curl "https://p.savenow.to/ajax/download.php?copyright=0&allow_extended_duration=1&format=mp3&url=VIDEO_URL&api=API_KEY"
```
返回 JSON：
```json
{
"success": true,
"id": "1CXjdNLFuewLXLBpOMu3BGJ",
"title": "视频标题",
"info": {
"title": "视频标题"
},
"progress_url": "https://p.savenow.to/api/progress?id=1CXjdNLFuewLXLBpOMu3BGJ"
}
```
**获取标题（Python）**：
```python
import json
import re
with open('response.json', 'rb') as f:
content = f.read()
match = re.search(rb'"title":"([^"]+)"', content)
escaped = match.group(1).decode('ascii')
title = bytes(escaped, 'ascii').decode('unicode_escape')
# title 就是视频标题
```
参数说明：
- `format`: 视频或音频格式
- `url`: YouTube 视频 URL
- `api`: API Key: `dfcb6d76f2f6a9894gjkege8a4ab232222`
- `copyright`: 0
- `allow_extended_duration`: 1
返回 JSON：
```json
{
"success": true,
"id": "1CXjdNLFuewLXLBpOMu3BGJ",
"progress_url": "https://p.savenow.to/api/progress?id=1CXjdNLFuewLXLBpOMu3BGJ"
}
```
### 2. 轮询下载链接
```bash
curl "https://p.savenow.to/api/progress?id=VIDEO_ID"
```
当 `success: 1` 且 `progress: 1000` 时，返回 `download_url`。
### 3. 下载文件
```bash
curl -L -o output.mp3 "DOWNLOAD_URL"
```
## Python 示例
```python
import requests
import time
API_KEY = 'dfcb6d76f2f6a9894gjkege8a4ab232222'
BASE_URL = 'https://p.savenow.to'
def download_youtube(url, format='mp3', output_path='output.mp3'):
# 1. 请求下载
params = {
'copyright': '0',
'allow_extended_duration': '1',
'format': format,
'url': url,
'api': API_KEY
}
resp = requests.get(f'{BASE_URL}/ajax/download.php', params=params)
data = resp.json()
if not data.get('success'):
raise Exception(f'Request failed: {data}')
progress_id = data['id']
progress_url = data['progress_url']
# 2. 轮询直到完成
while True:
time.sleep(3)
resp = requests.get(progress_url)
status = resp.json()
if status.get('success') == 1 and status.get('progress') == 1000:
download_url = status['download_url']
break
# 3. 下载文件
resp = requests.get(download_url, stream=True)
with open(output_path, 'wb') as f:
for chunk in resp.iter_content(chunk_size=8192):
f.write(chunk)
return output_path
# 使用
download_youtube('https://www.youtube.com/watch?v=VIDEO_ID', 'mp3', 'video.mp3')
```
## 注意事项
1. **API 不稳定时**: 会自动尝试备用 API (`p.lbserver.xyz`)
2. **下载链接有效期**: 获取后尽快下载
3. **支持地区**: API 可能因地区不同而有差异
4. **商业用途**: API 为免费使用，但有商业合作联系方式
