如何在Python请求中使用Cookie

本文介绍了如何在Python请求中使用Cookie的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试登录页面并访问页面中的另一个链接。

I am trying to login to a page and access another link in the page.

payload={'username'=<username>,'password'=<password>} with session() as s: r = c.post(<URL>, data=payload) print r print r.content

这给我一个 405 Not Allowed错误。 我使用chrome开发人员工具检查了发布方法的详细信息，并且可以看到一个api（URL / api / auth）。 我将带有有效负载的URL发布到该URL，并且该URL正在工作，并且得到的响应类似于在开发人员中看到的响应。

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.

不幸的是，尝试时登录后获取另一个网址，我仍然从登录页面获取内容。 为什么登录不固定？我应该使用Cookie吗？ 我是新手，所以我真的不知道如何使用Cookie。

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.

推荐答案

会话对象。它存储cookie，以便您可以发出请求，并为您处理cookie

You can use a session object. It stores the cookies so you can make requests, and it handles the cookies for you

s = requests.Session() # all cookies received will be stored in the session object s.post('www...',data=payload) s.get('www...')

文档： requests.readthedocs.io/en/master/user/advanced/#session-objects

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，而不必每次运行脚本时都登录：

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:
