如何设置自定义响应解码器假装？

Question

我将feign与OkHttpClient一起使用，并希望使用重试机制对返回状态代码200、ok和空正文的endpoint进行短轮询。用假动作可能吗？在状态代码2xx上没有调用自定义错误解码器。还有其他更喜欢的方式来进行短轮询吗？顺便说一句，我在用科特林。

将以下步骤添加到feign.builder():

    .decoder(object : Decoder {
        private val delegate = Decoder.Default() //Or whatever decoder you actually use
        override fun decode(response: Response, type: Type) {
            if (response.status() == 200 && (response.body() == null || response.body().length() == 0))
                throw RetryableException(
                    response.status(),
                    "Response body was empty",
                    response.request().httpMethod(),
                    null, //retry interval will be determined by Retryer
                    response.request()
                )
            else delegate.decode(response, type)
        }
    })
