Question

我正在学习如何使用python请求模块登录示例网站。这个 Video Tutorial 让我开始。从我在GoogleChrome＆gt; Inspect Element＆gt; NetworkTab中看到的所有Cookie中，我无法使用以下代码检索所有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

使用这个我只得到如下的csrftoken：

{'csrftoken': 'ePE8zGxV4yHJ5j1NoGbXnhLK1FQ4jwqO'}

但是在谷歌浏览器中，我看到除了csrftoken（sessionid，_gat，_ga等）之外的所有其他cookie： Google Chrome ScreenShot

我甚至尝试了here中的以下代码，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

输出：

<!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？感谢。

Answer 1

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wget，curl或httpie等工具检查它是否仅向页面发出请求（不运行JS代码）。

此服务器设置的唯一Cookie为csrftoken，如下所示：

$ wget --server-response 'http://www.noobmovies.com/accounts/login/?next=/'

请注意Set-Cookie行。

没有使用python请求模块获取所有cookie信息
