Hey everyone, I have pre existing Android application using

OKHTTP

client with some`interceptors` and

authenticator

and iOS application using

alamofire

with

interceptors

.Both projects are huge in size. Now I want to use KMM for new api client. So How can I use these 2 http client through Ktor. I don't want to write from scratch in KMM module. Any suggestion?

You can’t use them inside Ktor, since the client logic will need to be written in common code.

Do i need to use write from scratch?

Why do you want three API "clients"? OKHTTP, alamofire, AND Ktor?

I don't want to change my previous retrofit and alamofire code because my project is huge in size. Now I want to use KMM, and Ktor is way to connect both platform. But in my retrofit and alomofire has interceptor and authenticator. So I want same behaviour in ktor client. That's why I asked is there a way to use existing in ktor or not

Are you asking if you can use your existing implementation in KMM/Ktor, or are you asking if there are interceptors and authenticators in Ktor?

I am asking can I use my existing implementation in kmm/ktor or not ?

You’d need to reimplement everything in KTOR. You can try to do this in phases if your project allows you to do that, for example first do all unauthenticated calls then add the one that require authentication. Also remember that some of the custom interceptors/authenticators might not be needed in KTOR, as it has lots of features/plugins.

Ok that's great

You can configure the OkHttp engine to use your existing interceptors (see an example here). Unfortunately, for

alamofire

this not gonna work.

so I need to write logic in ios module?

Yes.
