提问by heisenberg
I am writing a script to log in to some webpage. I using request and request.session module for this purpose.On first request with login parameters server responses a session id.How to set that session id for further login to same page.
我正在编写一个脚本来登录某个网页。为此，我使用 request 和 request.session 模块。在第一个带有登录参数的请求中，服务器响应一个会话 ID。如何设置该会话 ID 以进一步登录到同一页面。
url = "some url of login page"
payload = {'username': 'p05989', 'password': '123456'}
with requests.session() as s:
s.post(url1, data=payload)
sessionid = s.cookies.get('SESSIONID')
print(sessionid)
r = requests.get(url,data=payload)
print(r.text)
in above code, server responses sessionid on first request.How to use that sessionid on second request?
在上面的代码中，服务器在第一个请求时响应 sessionid。如何在第二个请求中使用该 sessionid？

You are already using requests.session(); it handles cookies for you, provided you keep using the sessionfor all your requests:
您已经在使用requests.session()；它会为您处理 cookie，前提是您继续使用会话来处理您的所有请求：
url = "some url of login page"
payload = {'username': 'p05989', 'password': '123456'}
with requests.session() as s:
# fetch the login page
s.get(url)
# post to the login form
r = s.post(url1, data=payload)
print(r.text)
You probably do first need to use GETto get the session id set before posting to the login form.
GET在发布到登录表单之前，您可能首先需要使用来获取会话 ID 设置。
The SESSIONIDcookie is handled transparently for you.
该SESSIONIDCookie是你透明地处理。
