使用django python-social-auth重定向后，会话值丢失 [英] Session value missing after redirect with django python-social-auth
问题描述
我正在使用python-social-auth进行django项目来与Facebook进行身份验证。我在localhost上运行django服务器，并将我的应用程序设置为重定向到 http：//127.0 .0.1：8000 / complete / facebook / ，它开始使用python-social-auth的管道来验证用户。我使用postgres作为我的数据库。
I am working on a django project using python-social-auth to do authentication with facebook. I am running the django server on localhost and have facebook set up with my application to redirect to http://127.0.0.1:8000/complete/facebook/, which begins python-social-auth's pipeline to authenticate a user. I am using postgres as my database.
当调用此方法并尝试进行身份验证时，无法查找会话信息。从 https://github.com/omab/python-social-auth/issues/ 534 ，我认为sessionid cookie正在被覆盖。如果我将facebook重定向发送到不同的URL，以加载静态页面而不进行身份验证，那么没有错误，但是我也没有通过Facebook认证或获取任何信息。
When this method is called and tries to authenticate, it cannot find information on the session. From https://github.com/omab/python-social-auth/issues/534 , I think the sessionid cookie is being overwritten. If I send the facebook redirect to a different url to load a static page without authentication, there is no error but I am also not authenticating or getting any information from facebook.
我如何不覆盖sessionid cookie - 当然这是实际的问题 - 还有另一个可能在这里丢失的问题？ p>
How would I go about not overwriting the sessionid cookie -if of course, that is the actual issue- or is there another problem that I might be missing here?

推荐答案
此错误是由于会话cookie未被保存通过非https网址。当在本地主机上测试SESSION_COOKIE_SECURE在django中设置为True时，会话cookie不会在重定向之间持续，您将会在任何类型的页面更改中获取此错误，会话将被检查。
This error was due to the session cookie not being saved over a non-https url. When testing on localhost with SESSION_COOKIE_SECURE set to True in django, the session cookies will not persist between redirect and you will get this error in any kind of page change where session would be checked.
SESSION_COOKIE_SECURE =测试错误，一切都很好
SESSION_COOKIE_SECURE=False for testing and it's all good
