在WebFlux中格式化Wiretap输出

我按照https://www.baeldung.com/spring-log-webclient-calls进行操作，最终得到以下代码来格式化Netty的HttpClient转储的日志

public class HttpLoggingHandler extends LoggingHandler {

    public HttpLoggingHandler(Class<?> clazz) {
        super(clazz);
    }

    @Override
    protected String format(ChannelHandlerContext ctx, String event, Object arg) {
        if (arg instanceof ByteBuf) {
            ByteBuf msg = (ByteBuf) arg;
            String output = msg.toString(StandardCharsets.UTF_8);
            return output;
        }

        return super.format(ctx, event, arg);
    }

    @Override
    public void channelActive(ChannelHandlerContext ctx) {
        ctx.fireChannelActive();
    }

    @Override
    public void channelReadComplete(ChannelHandlerContext ctx) throws Exception {
        ctx.fireChannelReadComplete();
    }

    @Override
    public void channelRegistered(ChannelHandlerContext ctx) throws Exception {
        ctx.fireChannelRegistered();
    }

    @Override
    public void channelUnregistered(ChannelHandlerContext ctx) throws Exception {
        ctx.fireChannelUnregistered();
    }

    @Override
    public void channelInactive(ChannelHandlerContext ctx) throws Exception {
        ctx.fireChannelInactive();
    }

    @Override
    public void flush(ChannelHandlerContext ctx) throws Exception {
        ctx.flush();
    }

}

我最终得到了以下日志输出。

这是对十六进制转储的巨大改进，但是有没有办法识别标题/ cookie和请求/响应主体？我看到请求日志的最后一行是请求正文

{"id":4,"productId":4,"customer":{"firstName":"John","lastName":"Doe","email":"john@gmail.com"}}

但有时请求主体会像这样单独转储：

2019-12-26 15:14:17.495 DEBUG 30176 --- [ctor-http-nio-7] reactor.netty.http.client.HttpClient     : {"id":4,"productId":4,"customer"{"firstName":"John","lastName":"Doe","email":"john@gmail.com"}}

我尝试arg以的身份进行检查instanceof HttpContent/HttpRequest，但没有运气。

我可以通过使用cookieBytebuf输出中的键来获取标头（使用HTTPHeaders映射）和cookie ，但是我不确定要获取请求/响应主体的方法，因为它以不同的顺序以不同的顺序打印。有办法解决吗？
