Python爬虫可以用来爬取音频文件。你可以使用Python的requests库发送HTTP请求来获取网页内容,然后使用正则表达式或其他解析库来提取音频文件的URL。接下来,你可以使用requests库再次发送HTTP请求来下载音频文件并保存到本地。
以下是一个示例代码,用于爬取音频文件:
```python
import requests
import re
# 设置请求头
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36'
}
# 发送请求获取网页内容
url = 'https://music.163.com/discover/toplist?id=3778678'
response = requests.get(url=url, headers=headers)
html_data = response.text
# 解析数据,提取音频文件URL
info_list = re.findall(r'lio<a href="/song \?id=(.*?)"">(.*?)</a></li>', html_data)
for music_id, title in info_list:
music_url = f'http://music.163.com/song/media/outer/url?id={music_id}.mp3'
music_content = requests.get(url=music_url, headers=headers).content
# 保存音频文件
with open(title + '.mp3', mode='wb') as f:
f.write(music_content)
print(f'{title} 下载完成')
```
请注意,这只是一个示例代码,具体的爬取方法可能因网站结构的不同而有所差异。在实际应用中,你可能需要根据目标网站的具体情况进行适当的调整和优化。
