## Status
|
|
|
|
- Issue:
|
|
|
|
[1974](https://github.com/linagora/tmail-flutter/issues/1974)
|
|
|
|
## Context
|
|
|
|
- Requests still return `401` after retrieving a new token. The application automatically logs out
|
|
|
|
## Root cause
|
|
|
|
- When executing tasks concurrently, they are pushed into the `Queue` along with the old `header` values (the old authentication is retained).
|
|
So when the first request receives a `401` error and tries to get a new token, it will be updated with the new authentication header value.
|
|
|
|
## Decision
|
|
|
|
- Use `QueuedInterceptor` to serialize `requests/responses/errors` before they enter the interceptor.
|
|
If there are multiple concurrent requests, the request is added to a queue before entering the interceptor.
|
|
Only one request at a time enters the interceptor, and after that request is processed by the interceptor, the next request will enter the interceptor.
|
|
- Try to make a `retry` request up to 3 times when receiving a `401` error. Aims to update the new token value on `memmory` to requests in the `queue`.
|
|
|
|
## Consequences
|
|
|
|
- The following `requests` were completed successfully. The application is not automatically logged out
