功能：获取音乐记录的Youtube URL

import urllib.request
import re
 
def fetch_webpage(url):
    # 使用urllib.request.urlopen打开网页
    with urllib.request.urlopen(url) as response:
        # 读取网页内容，response.read() 获取的是字节数据
        html_content = response.read()
 
        # 将字节数据解码为字符串
        html_text = html_content.decode('utf-8')
        return html_text
 
def find_youtube_urls(html_text):
    # 使用正则表达式查找所有的 URL
    urls = re.findall(r'href=["\'](https?://[^"\' ]+)', html_text)
 
    # 筛选出包含 "youtube.com" 的 URL
    youtube_urls = [url for url in urls if "youtube.com" in url]
    return youtube_urls
 
# 调用函数，你可以替换下面的 URL 为你需要的网址
url = 'https://wiki.gzher.com/doku.php?id=%E8%AF%AD%E8%A8%80:%E9%9F%B3%E4%B9%90'
webpage_content = fetch_webpage(url)
 
# 查找包含 "youtube.com" 的 URL
youtube_urls = find_youtube_urls(webpage_content)
print("Found YouTube URLs:")
for url in youtube_urls:
    print(url)
