python如何在重定向后获得最终目的地

import requests

def get_final_destination(url):
    response = requests.get(url, allow_redirects=False)
    if response.status_code == 301 or response.status_code == 302:
        redirect_url = response.headers['Location']
        return get_final_destination(redirect_url)
    else:
        return response.url

# 示例用法
url = "http://example.com"
final_destination = get_final_destination(url)
print("最终目的地：", final_destination)
