如何从我收到的电子邮件中的超链接中提取URL？

import re
import email

def extract_urls_from_email(email_content):
    # 解析电子邮件
    msg = email.message_from_string(email_content)
    
    # 获取正文内容
    body = ""
    if msg.is_multipart():
        for part in msg.walk():
            content_type = part.get_content_type()
            if content_type == "text/plain" or content_type == "text/html":
                body = part.get_payload(decode=True).decode()
                break
    else:
        body = msg.get_payload(decode=True).decode()
    
    # 提取URL
    urls = re.findall(r'http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\\(\\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+', body)
    
    return urls

# 示例用电子邮件内容
email_content = '''
    From: sender@example.com
    To: recipient@example.com
    Subject: Example Email
    
    This is an example email with a URL: https://example.com
'''

# 提取URL
urls = extract_urls_from_email(email_content)
print(urls)
