Hi there,

Why Ktor can not read response twice? Anyone find a workaround for this issue by any chance?

It's getting super frustrating to handle this logic in an interceptor for a kmm project.

Can this one be used in kmm clients?

[rocketraman]

That's a server plugin, so I guess no.

For the client I think you would just save the response locally and do what you want with it.

@Randy Tang do you try to receive a response body from a response validator?

[Randy Tang]

@Aleksei Tirman [JB] no, I'm intercepting certain api responses with status code 200. Those api had access token error encapsulated in 200 and I want those errors to trigger refresh logic.
However for a correct response, after the unwrapped the response body, it becomes empty for the upper layer

Can you share some of your interception code?

Ktor HTTP client can read a response twice, but it has the problem of reading it in an HTTP response validator.
