How to use cookies in Python Requests
提问by user1474157
I am trying to login to a page and access another link in the page.
我正在尝试登录一个页面并访问该页面中的另一个链接。
payload={'username'=<username>,'password'=<password>}
with session() as s:
r = c.post(<URL>, data=payload)
print r
print r.content
This is giving me a "405 Not Allowed" error. I checked the post method details using chrome developer tools and could see an api (URL/api/auth). I posted to that URL with the payload and it was working and i was getting a response similar to what i could see in the developer.
这给了我一个“405 Not Allowed”错误。我使用 chrome 开发人员工具检查了 post 方法的详细信息，可以看到一个 api (URL/api/auth)。我使用有效负载发布到该 URL 并且它正在工作，并且我收到了类似于我在开发人员中看到的响应。
Unfortunately when trying to 'get' another url after login, i am still getting the content from the login page. Why is the login not sticking? Should i use cookies? I am a newbie, so i don't really know how to work with cookies.
不幸的是，在登录后尝试“获取”另一个 url 时，我仍然从登录页面获取内容。为什么登录不卡？我应该使用cookies吗？我是新手，所以我真的不知道如何使用 cookie。

From the documentation:
从文档：
get cookie from response
url = 'http://example.com/some/cookie/setting/url' r = requests.get(url) r.cookies{'example_cookie_name': 'example_cookie_value'}give cookie back to server on subsequent request
url = 'http://httpbin.org/cookies' cookies = dict(cookies_are='working') r = requests.get(url, cookies=cookies)`
从响应中获取 cookie
url = 'http://example.com/some/cookie/setting/url' r = requests.get(url) r.cookies{'example_cookie_name': 'example_cookie_value'}在后续请求时将 cookie 返回给服务器
url = 'http://httpbin.org/cookies' cookies = dict(cookies_are='working') r = requests.get(url, cookies=cookies)`

You can use a session object. It stores the cookies so you can make requests, and it handles the cookies for you
您可以使用会话对象。它存储 cookie 以便您可以提出请求，并为您处理 cookie
s = requests.Session()
# all cookies received will be stored in the session object
s.post('http://www...',data=payload)
s.get('http://www...')

You can also save the cookie data to an external file, and then reload them to keep session persistent without having to login every time you run the script:
您还可以将 cookie 数据保存到外部文件，然后重新加载它们以保持会话持久性，而无需每次运行脚本时都登录：
