我正在学习如何使用 python requests 模块登录示例网站。这视频教程 https://www.youtube.com/watch?v=eRSJSKG4mDA让我开始了。从我在 Google Chrome>Inspect Element>Network Tab 中看到的所有 cookie，我无法使用以下代码检索所有这些 cookie：
import requests
with requests.Session() as s:
url = 'http://www.noobmovies.com/accounts/login/?next=/'
s.get(url)
allcookies = s.cookies.get_dict()
print allcookies
使用这个我只能得到如下所示的 csrftoken：
{'csrftoken': 'ePE8zGxV4yHJ5j1NoGbXnhLK1FQ4jwqO'}
But in google chrome, I see all these other cookies apart from csrftoken (sessionid, _gat, _ga etc):
我什至尝试了以下代码here https://stackoverflow.com/questions/20898394/how-to-read-cookie-in-python，但结果是一样的：
from urllib2 import Request, build_opener, HTTPCookieProcessor, HTTPHandler
import cookielib
#Create a CookieJar object to hold the cookies
cj = cookielib.CookieJar()
#Create an opener to open pages using the http protocol and to process cookies.
opener = build_opener(HTTPCookieProcessor(cj), HTTPHandler())
#create a request object to be used to get the page.
req = Request("http://www.noobmovies.com/accounts/login/?next=/")
f = opener.open(req)
#see the first few lines of the page
html = f.read()
print html[:50]
#Check out the cookies
print "the cookies are: "
for cookie in cj:
print cookie
Output:
<!DOCTYPE html>
<html xmlns="http://www.w3.org
the cookies are:
<Cookie csrftoken=ePE8zGxV4yHJ5j1NoGbXnhLK1FQ4jwqO for www.noobmovies.com/>
那么，我怎样才能获得所有的cookie呢？谢谢。
正在设置的 cookie 来自其他页面/资源，可能由 JavaScript 代码加载。您可以使用以下工具检查它仅向页面发出请求（不运行 JS 代码）wget https://www.gnu.org/software/wget/, curl https://curl.haxx.se/ or httpie https://pypi.python.org/pypi/httpie.
该服务器设置的唯一 cookie 是csrftoken，如您所见：
$ wget --server-response 'http://www.noobmovies.com/accounts/login/?next=/'
