如何使用Python从电子邮件中提取长URL？

import re
from urllib.parse import urlparse

def extract_long_url(email):
    # 正则表达式匹配URL
    url_pattern = r'(https?://\S+)'
    matches = re.findall(url_pattern, email)
    
    # 返回第一个匹配到的URL
    if matches:
        return matches[0]
    else:
        return None

def parse_url(url):
    parsed_url = urlparse(url)
    return parsed_url

email = "这是一封包含长URL的电子邮件，URL为https://www.example.com"
long_url = extract_long_url(email)
if long_url:
    parsed_url = parse_url(long_url)
    print("长URL:", long_url)
    print("协议:", parsed_url.scheme)
    print("域名:", parsed_url.netloc)
    print("路径:", parsed_url.path)
    print("查询参数:", parsed_url.query)
    print("锚点:", parsed_url.fragment)
else:
    print("未找到长URL")

长URL: https://www.example.com
协议: https
域名: www.example.com
路径: /
查询参数: 
锚点:
