成功登录会话后Python请求GET失败

因此，我使用Python请求库登录到PHP WebCM。到目前为止，我能够使用post命令和有效负载登录。我可以下载一个文件

问题是：当我在通过POST登录后运行GET命令时，它告诉我我不再登录了——尽管我仍然在使用同一个会话！请看一下代码

#Lets Login
with requests.session() as s:
payload = {'username': strUserName, 'password': strUserPass, 'Submit':'Login'}
r = s.post(urlToLoginPHP, data=payload, stream=True)
#Ok we are logged in. If I would run the #DOWNLOADING Files code right here I would get a correct zip file
#But since the r2-Get-Command delivers the "please login" page it doesn't work anymore
r2 = s.get("urlToAnotherPageOfThisWebsite",stream=True)
#We are not logged in anymore

#DOWNLOADING Files: This now just delivers a 5KB big file which contains the content
 of the "please login page"
local_filename = 'image.zip'
# NOTE the stream=True parameter
r1 = s.get(downloadurl, stream=True)
with open(local_filename, 'wb') as f:
    for chunk in r1.iter_content(chunk_size=1024): 
        if chunk: # filter out keep-alive new chunks
            f.write(chunk)
            f.flush()

我找到了解决方案：我登录到浏览器，同时尝试通过python登录。网站注意到我已经登录了，我误解了
