print (r1.cookies)

d=s.get(durl)
print (d.cookies)

dsoup=BeautifulSoup(r1.content)
print (dsoup)

但问题是cookies没有保存到会话中，我作为登录用户无法进入下一页。在

有人能给我一些建议吗。 谢谢。在

Answer 1

当您发布到登录页面时：

r1=s.post(URL, data=login_data)

它可能会发出重定向到另一个页面。因此，对POST请求的响应返回响应中的cookies，然后重定向到另一个页面。重定向是在r1中捕获的内容，不包含cookies。在

尝试相同的命令，但不允许重定向：
