Disable redirects in OkHttp3 for ONE request only-CodePudding

I have a singleton (object in Kotlin) that holds an instance of OkHttpClient which as per the search on stack is the way to go.

Now I come to the scenario where for just ONE request in my app I need to skip the redirect to get the Location header.

It seems that the way to do it is via

val client = OkHttpClient.Builder()
            .followRedirects(false)
            .followSslRedirects(false)
            .build()

This is fine and dandy, but now I need to store two instances of OkHttpClient and the non-redirecting one is not even to be always used coz it pertains to a login flow for my app only.

Is it possible (e.g. via writing a network interceptor maybe?) to disable redirect for just ONE request?

CodePudding user response：

Per the docs, you should use one main instance, and then build customizations off of that base instance.

// renamed solely to make it clear what's going on below
val commonClient = OkHttpClient.Builder()
                   .followRedirects(true) // you can skip these calls, they are true by default
                   .followSslRedirects(true)
                   .build()

Then later on, in your "do login" function, you'd create a fork of the base client. Under the hood, everything will still use commonClient but any requests made using this "new" client will use the settings you overrode. It's just a bit of an odd, roundabout syntax.

// fork the base instance
val noRedirectClient = commonClient.newBuilder()
                       .followRedirects(false) // override the previous/default settings used by commonClient
                       .followSslRedirects(false)
                       .build()

// make your request(s)

// don't shutdown noRedirectClient, because it would also shutdown the
// underlying commonClient instance because they share resources
