如何在Netty客户端漂亮地打印http正文？

import io.netty.buffer.ByteBuf;
import io.netty.channel.ChannelHandlerContext;
import io.netty.channel.ChannelInboundHandlerAdapter;
import io.netty.handler.codec.http.FullHttpResponse;

public class HttpResponseHandler extends ChannelInboundHandlerAdapter {

    @Override
    public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
        if (msg instanceof FullHttpResponse) {
            FullHttpResponse response = (FullHttpResponse) msg;
            ByteBuf content = response.content();
            String body = content.toString();
            System.out.println("HTTP Body: " + body);
        }
        ctx.fireChannelRead(msg);
    }
}
