BearerTokenPlugin

A Ktor HttpClient plugin that attaches Bearer tokens to outgoing requests.

On each request, calls the configured BearerTokenPluginConfig.accessTokenProvider and, if a non-empty token is returned, adds an Authorization: Bearer {token} header. If no token is available and BearerTokenPluginConfig.eventsFlow is configured, emits a NoAccessTokenAvailableEvent.

This is the KMP equivalent of the Android-only AccessTokenInterceptor for OkHttp.

Example usage with a Credential:

val client = HttpClient {
    install(BearerTokenPlugin) {
        credential = myCredential
        eventsFlow = myEventsFlow
        accessTokenProvider = {
            myCredential.refreshIfExpired().getOrNull()?.token?.accessToken
        }
    }
}

Example usage with a fixed token:

val client = HttpClient {
    install(BearerTokenPlugin) {
        accessTokenProvider = { "my-access-token" }
    }
}
