Hi, with ktor client, is there a equivalent of okhttp interceptors or authenticator?

As server part its features you add to the client. See: https://ktor.io/docs/features-auth.html#providers

I mean okhttp has Authenticator feature which callbacks get called when you receive a 401 so you can refresh token, provide basic auth too but mostly to globally refresh the token. Now with ktor it seems I need to check for this manually on every callsite Interceptors detto

@ursus Your use case is OAuth2, right?

well sort of, just access+refresh token pattern

I didn't try this yet (made a half-broken homegrown one that I plan to revisit or replace), but here's an article that guides you using an open source library that has a ktor feature for that: https://medium.com/l-r-engineering/oauth2-in-android-authorization-code-flow-ffc4355dd473

thx!

Hi! 👋 So many channels I didn’t spot this one 🙂 You can use this feature from @Kurt Renzo Acosta which works perfectly for intercepting unauthorized responses https://github.com/kuuuurt/ktor-client-oauth-feature

I haven’t been updating that library though. Feel free to file an issue if it doesn’t suit your use case and I’ll see what I can do!
