Encountered the same problem.

[marhali]

Same problem here.

[JackyChan]

It seems that decode packet with namespace incorrect. I fixed that by modify the com.corundumstudio.socketio.protocol.PacketDecoder. readNamespace(ByteBuf frame) method. I have not test it deeply. But it solved the problem. The code is here.

    private String readNamespace(ByteBuf frame) {
        /**
         * namespace post request with url queryString, like
         *  /message?a=1,
         *  /message,
         */
        int endIndex = frame.bytesBefore((byte)'?');
        if(endIndex > 0){
            return readString(frame,endIndex);
        }
        endIndex = frame.bytesBefore((byte)',');
        if(endIndex > 0){
            // modified is here, just skip the ',' after namespace
            String nsp = readString(frame,endIndex);
            frame.readByte(); // skip ,
            return nsp;
        }
        return readString(frame);
    }

good good @JackyChan

我也遇到了这个问题，有命名空间始终会有这个错误，没有命名空间就不会
