从这个Python代码中，
...
resp = logout_session.get(logout_url, headers=headers, verify=False, allow_redirects=False)
soup = BeautifulSoup(resp.content, "html.parser")
print(soup.prettify())
我能够进行API调用，响应内容如下:
<!DOCTYPE html>
<html>
<head>...</head>
<body>
<div class="container">
<div class="title logo" id="header">
<img alt="" id="business-logo-login" src="/customviews/image/business_logo:f0a067275aba3c71c62cffa2f50ac69c/"/>
</div>
<div class="input-group alert alert-success text-center" id="title" role="alert">
Successfully signed out
</div>
<div class="input-group alert text-center">
<a href="/saml-idp/portal/">
Login again
</a>
</div>
<div>
<p>
You will be redirected to https://idpftc.business.com/saml/Gy736KPK3v1aWDPECRZKAn/proxy_logout/ after 5 seconds ...
</p>
<script language="javascript" nonce="">
window.onload = window.setTimeout(function() {
window.location.replace("https://idpftc.business.com/saml/Gy736KPK3v1aWDPECRZKAn/proxy_logout/?SAMLResponse=3VjJkuNIjv2VtKijLJObJIphlWnGfd93Xtoo7vsukvr6ZkRU");}, 5000);
</script>
</div>
</div>
</body>
</html>
现在我想提取html链接:
https://idpftc.business.com/saml/Gy736KPK3v1aWDPECRZKAn/proxy_logout/?SAMLResponse=3VjJkuNIjv2VtKijLJObJIphlWnGfd93Xtoo7vsukvr6ZkRU
从这篇内容中，有谁知道如何用PYTHON来做到这一点？
