如何覆盖logRequest/logResponse以在Ktor客户端日志记录中记录自定义消息？

class CustomLogWriter : LogWriter {
    override fun logRequest(config: HttpClientConfig<*>, request: HttpRequestBuilder) {
        // 在这里记录请求信息
    }

    override fun logResponse(config: HttpClientConfig<*>, request: HttpRequestBuilder, response: HttpResponse) {
        // 在这里记录响应信息
    }
}

val client = HttpClient {
    install(Logging) {
        logger = Logger.SIMPLE
        level = LogLevel.ALL
        writer = CustomLogWriter() // 添加自定义日志处理程序
    }
}

class CustomLogWriter : LogWriter {
    override fun logRequest(config: HttpClientConfig<*>, request: HttpRequestBuilder) {
        // 记录自定义消息
        logger.info("Custom log message for request: ${request.url}")
        
        // 记录请求信息
        logger.info("Method: ${request.method}")
        logger.info("Headers: ${request.headers.entries()}")
        logger.info("Body: ${request.body}")
    }

    override fun logResponse(config: HttpClientConfig<*>, request: HttpRequestBuilder, response: HttpResponse) {
        // 记录自定义消息
        logger.info("Custom log message for response: ${response.status}")

        // 记录响应信息
        logger.info("Headers: ${response.headers.entries()}")
        logger.info("Body: ${response.readText()}")
    }
}
