UNet客户端断开错误：在NetworkClient.Connect上的CRCMismatch

问题描述：

我需要一些真正的帮助。我不确定如何解决CRC不匹配错误。所有我想要做的是从我的客户端发送一个字节数组到我的服务器，我得到这个错误：UNet客户端断开错误：在NetworkClient.Connect上的CRCMismatch

UNet Client Disconnect Error: CRCMismatch UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

我一直想了一个多月，现在连接点并获得网络要正确操作，但我迈出的每一步，都会导致回退五步。我基本上都在圈子里，我已经完成了每一个存在的统一网络教程，我仍然很迷茫。我真的需要帮助解决这个问题。有人能帮助我吗？我还附上了下面的完整代码。先谢谢你！

AnimalDataMsgType类

public class AnimalDataMsgType 
{ 
    public static short animalData = MsgType.Highest + 1; 
    public static short SYSTEM_CONNECT = MsgType.Connect; 
    public static short SYSTEM_DISCONNECT = MsgType.Disconnect; 
    public static short SYSTEM_ERROR = MsgType.Error; 
}

AnimalData类

public class AnimalData : MessageBase 
{ 
    public byte[] Tex;  // data coming from CanvasController 
    public string Type;  // data coming from CanvasController 
    public string Id;  // data coming from GameManager 
    public int Strength; // data coming from PlayerController 
    public int Hitpoints; // data coming from PlayerController 
    public bool IsAlive; // data coming from PlayerController 
}

你能否提供AnimalDataMsgType和AnimalData类？那么，我可以尝试弄清楚它？ – ZayedUpal

@ZayedUpal我刚刚在帖子末尾添加了这些类 – greyBow

HLAPI CRC是已知NetworkBehaviour脚本和它们使用的通道（与NetworkSettingsAttribute一起）的哈希。是的，如果两个不同（并且不兼容）的Unity项目或同一个项目的版本彼此交谈，则会发生这种情况。尝试重建您的应用程序（或应用程序，如果客户端和服务器是分开的）。如果你改变一些网络代码，并忘记重建，可能会导致这种情况。 –

我通过client.Connect(serverIP, port);前右加client.Configure(cc, 1);解决我的问题。问题是我的NetworkClient客户端connectionConfig配置文件需要设置为与我的NetworkTransport HostTopology中定义的配置设置相同，并且未将connectionConfig设置为我的客户端。连接功能导致CRC不匹配。另外，在创建我的NetworkClient实例后发送消息时，我使用client.SendByChannel，因此我可以设置我的channelId。
