Я реализовал grpc API с Vertx с использованием Kotlin и включил уровни FINEST log для целей отладки.В моих интеграционных тестах я пытаюсь подключить клиент grpc к серверу по каналу.
Фрагмент клиента:
val clientAsync1 = ctx.async()
val channel1 = VertxChannelBuilder
.forAddress(vertx, "localhost", 10000)
.usePlaintext(true)
.build()
val stub1 = ExampleGrpc.newVertxStub(channel1)
val request = builderUtil.buildRequest()
stub1.attemptFriendship(request) { stream ->
stream.handler { response ->
}
}
В журналах в моем журнале я вижу следующееgrpc ver ver:

Может кто-нибудь объяснить, что означает [{0}]{1}{2}
