Description

Discord recently changed their domain from discordapp.com to discord.com (the cdn is still on discordapp.com) meaning that the domains used need to be updated

Can someone review this asap? It has all sorts of weird behavior because it gets redirected to discord.com

Temp fix is to add an interceptor for now

private val oAuth2Client = OAuth2Client.Builder()
.setClientId(config.discord.oauth.clientId)
.setClientSecret(config.discord.oauth.clientSecret)
.setOkHttpClient(
    OkHttpClient.Builder()
        .addInterceptor {
            var request = it.request()
            val httpUrl = request.url()

            if (httpUrl.host().contains("discordapp")){
                val newHttpUrl = httpUrl.newBuilder()
                    .host("discord.com")
                    .build()

                request = request.newBuilder()
                    .url(newHttpUrl)
                    .build()
            }

            it.proceed(request)
        }
        .build()
)
.build()
