如何限制服务器接收到的websocket帧的净长度 [英] How to limit in netty length of websocket frame received by server

问题描述

我正在使用netty 3.4实现WebSocket服务.

I am implementing a WebSocket service using netty 3.4.

我需要限制帧大小，以避免非常长的帧发生DoS攻击.我希望在32KB数据之后删除连接，即使该帧尚未完成并且还没有传递给我的处理程序.

I need to limit the frame size to avoid DoS attacks with very very long frames. I want the connection to be dropped after 32KB of data, even if the frame was not finished yet and it was not passed to my Handler.

有什么办法吗?

推荐答案

给出

Given the code as it stands at the moment, doesn't look like it at the moment.

您将必须扩展WebSocket08FrameDecoder并更改toFrameLength()中的代码.

You will have to extend WebSocket08FrameDecoder and change the code in toFrameLength().

如果有机会，我会提出下一个发布请求.

If I get a chance, I'll put in a pull request for the next release.
