我尝试与另一个WebsocketServer通信，该WebsocketServer需要以如下形式获取其消息： [byte []控制字节，数据] 例如，有效的传入消息如下：
+-------------------------------------------------+
| 0 1 2 3 4 5 6 7 8 9 a b c d e f |
+--------+-------------------------------------------------+----------------+
|00000000| 01 7b 22 63 6f 6e 6e 65 63 74 69 6f 6e 48 65 6c |.{"connectionHel|
|00000010| 6c 6f 22 3a 5b 7b 22 70 68 61 73 65 22 3a 22 72 |lo":[{"phase":"r|
|00000020| 65 61 64 79 22 7d 2c 7b 22 77 61 69 74 69 6e 67 |eady"},{"waiting|
|00000030| 22 3a 36 30 30 30 30 7d 5d 7d |":60000}]} |
+--------+-------------------------------------------------+----------------+
当我尝试发送回复时，它会像这样改变。 在输入HttpClientCodec之前：
+-------------------------------------------------+
| 0 1 2 3 4 5 6 7 8 9 a b c d e f |
+--------+-------------------------------------------------+----------------+
|00000000| 00 01 7b 22 63 6f 6e 6e 65 63 74 69 6f 6e 48 65 |..{"connectionHe|
|00000010| 6c 6c 6f 22 3a 5b 7b 22 70 68 61 73 65 22 3a 22 |llo":[{"phase":"|
|00000020| 72 65 61 64 79 22 7d 2c 7b 22 77 61 69 74 69 6e |ready"},{"waitin|
|00000030| 67 22 3a 36 30 30 30 30 7d 5d 7d |g":60000}]} |
+--------+-------------------------------------------------+----------------+
在HttpClientCodec处理该消息之后：
+-------------------------------------------------+
| 0 1 2 3 4 5 6 7 8 9 a b c d e f |
+--------+-------------------------------------------------+----------------+
|00000000| 82 bb 2f df ee 2e 2f de 95 0c 4c b0 80 40 4a bc |../.../...L..@J.|

不知道这是否有帮助，但这是我配置管道的方式：
p.addLast(ClientSslHandler);
p.addLast(
new LoggingHandler(LogLevel.INFO),
new HttpClientCodec
new LoggingHandler(LogLevel.INFO),
new HttpObjectAggregator(8192),
new WebSocketClientProtocolHandler(wsHandShaker,true),
new SimpleChannelInboundHandler<TextWebSocketFrame>() {
@Override
protected void channelRead0(ChannelHandlerContext ctx, TextWebSocketFrame frame) throws Exception {
System.out.println(frame.text());
}
});
我不确定这是否是解决此问题的正确方法，因为我还没有完全了解HttpClientCodec的内部工作原理。但是希望答案能给我正确的方向。谢谢！
