错误信息“xeaThe client frame was not masked but all client frames must be masked” 后面查找资料发现需要按照websocket协议来发送websocket结构体的消息帧。
如下图 WebSocket 消息帧结构 FIN1位: 表示是否是最后一帧。 RSV1, RSV2, RSV3各1位: 保留位通常为 0。 Opcode4位: 帧的类型例如文本帧、二进制帧、关闭帧等。 Mask1位: 表示负载是否被掩码。 Payload length7/716/764位: 表示负载数据的长度。 Masking key32位: 如果 Mask 为 1则存在掩码键。 Payload data: 实际传输的数据。
找了一大堆资料结果还是没成功一想到有开源的websocket开源代码里面肯定是有发送消息的方法。得按照这个思路在websocket-sharp开源里找到了然后在里面看啊看游啊游头都要大了最后还是仿写了一套相对简单的后面一试成功了不容易啊。
