WebSocket发送消息，大于126字节和大于65535字节的处理

网上搜了一下WebSocket的合包函数，发现不能直接使用。查了很多资料，终于弄出来了，大于65535字节的没有测试，但是小于65535的测试通过下面是C#代码，其他代码根据此代码修改即可public static byte[] PackData(string message) { byte[] contentBytes = null; byte[] temp = Encoding.UTF8.GetBytes(message); LogWrite("内容长度：" + temp.Length); if (temp.Length < 126) { contentBytes = new byte[temp.Length + 2]; contentBytes[0] = 0x81; contentBytes[1] = (byte)temp.Length; Array.Copy(temp, 0, contentBytes, 2, temp.Length); } else if (temp.Length < 0xFFFF) { contentBytes = new byte[temp.Length + 4]; contentBytes[0] = 0x81; contentBytes[1] = 126; contentBytes[2] = (byte)(temp.Length >>8); contentBytes[3] = (byte)(temp.Length & 0xFF); Array.Copy(temp, 0, contentBytes, 4, temp.Length); } else { contentBytes = new byte[temp.Length + 10]; contentBytes[0] = 0x81; contentBytes[1] = 127; contentBytes[2] = 0; contentBytes[3] = 0; contentBytes[4] = 0; contentBytes[5] = 0; contentBytes[6] = (byte)(temp.Length >>24); contentBytes[7] = (byte)(temp.Length >>16); contentBytes[8] = (byte)(temp.Length >>8); contentBytes[9] = (byte)(temp.Length & 0xFF); Array.Copy(temp, 0, contentBytes, 10, temp.Length); }
return contentBytes; }
