Using OAuth2 in FastAPI, the backend sets up a redirect with a state value. However, when the frontend processes the redirection and sends the code along, session details are lost. How can this be resolved?
hey, try savin the state value in browser localstorage before redirecting. when user returns, grab it to re-associate the session. worked fine in my few projects tho not the most elegant method
The solution involves ensuring state persists across the OAuth2 flow despite external redirects. In my experience, storing the state parameter in a secure, HTTP-only cookie before the redirect and then retrieving it once the user returns to the frontend has proven effective. This method prevents the loss of session details while handling external redirection. Additionally, maintaining a mapping between the state value and session information either in a database or a caching system can further stabilize the process. Verifying token integrity on the backend helps ensure a secure and reliable flow.
hey guys, im wonderin if using jwt might fix the state loss issue? like store the state in a token that survives the redirect. curious if anyone tested this approach, and what about device performance? what do yall think, any fun experiences?
In my experience, maintaining state during OAuth2 flows can be challenging when redirects disrupt session continuity. A solution that worked for me involved storing the state on the server side using a session management system. By generating a session identifier and saving associated state details in a shared storage system or database, the frontend can pass the identifier on return. This approach ensures that even if the user’s session on the client side appears lost, the corresponding state can still be retrieved securely on the backend, preserving session integrity.
