简介：小红书手机app分享的链接需要点击才能获取完成链接，本文教大家如何通过代码的方式将xhs的短连接转化为长链接。

1.正常我们分享的链接是这样的：

44 小猪吃宵夜发布了一篇小红书笔记，快来看吧！ 😆 KeA1GIGiSMXGWy7 😆 http://xhslink.com/a/sT7omKb6ijX6，复制本条信息，打开【小红书】App查看精彩内容！

转换后是这样的：

2.我们先写个代码定义提取这段文字的链接部分

def extract_url(text):# 正则表达式匹配小红书短链pattern = r'http://xhslink\.com/\S+'match = re.search(pattern, text)if match:return match.group(0)  # 返回匹配到的链接else:return "未找到链接"

3. 接着我们将获取的链接通过重定向的方式获取到完整链接：

def get_redirect_url(short_url):try:# 添加请求头，模拟浏览器请求headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36","Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8","Accept-Language": "en-US,en;q=0.9","Connection": "keep-alive",}# 发送请求，禁止自动重定向response = requests.get(short_url, headers=headers, allow_redirects=False)# 检查响应状态码if response.status_code in [301, 302, 307]:  # 处理重定向状态码redirect_url = response.headers['Location']  # 获取重定向链接return redirect_urlelse:return "无法获取重定向链接，状态码: {}".format(response.status_code)except Exception as e:return "请求失败: {}".format(str(e))

4.我们运行代码就会得到这样的链接：

完整链接: https://www.xiaohongshu.com/discovery/item/677e4920000000000800d083?app_platform=ios&app_version=8.69.4&share_from_user_hidden=true&xsec_source=
