Description

Issues closed while still open. Cookie based authentication is at this moment not usable. This is partially due to the following issues:

• https://github.com/facebook/react-native/issues/23005 //TL;DR can only ever work with one cookie on Android
• https://github.com/facebook/react-native/issues/929 //TL;DR redirect: 'manual' doesnt work

These issues have been closed even though they are still open and very relevant.
There's more around cookies/fetch that i will try to hunt down in the following days. E.g one of the two platforms, i believe iOS , wont store cookies after app restart.

Conclusion

In general cookie based authentication is very problematic on multiple levels. If cookie based authentication is claimed implied to be supported on React Native and developers unknowingly structure their architecture around this these issues need attention. Otherwise people need to know before implementing a project using such an authentication mechanism as dozens of hours could be spend working on an architecture that is inevitably simply not supported.

This is not a matter of pointing fingers or demanding features. It is currently unfortunately misleading to leave people unaware of all these limitations as they might set out to create an architecture that's unsupported as i have.

At the very least maybe we should revise the documentation of fetch and explain how some things like "redirect:manual" dont work right now.

まず、関連する issue 23005 と 929 を確認し、次に React Native の fetch ドキュメントと、報告されている Android および iOS での cookie の挙動を調査します。この issue には単一の受け入れ基準はありません。完了とするには、説明されている cookie とリダイレクトの制限を解決するか、再起動後の挙動を含め、それらの制限を明確に文書化する必要があります。
