儘管將ReliableFragmented通道分配給網絡管理器，但緩衝區仍然太大錯誤

我在發送大約1.5 mb的圖像文件時遇到了網絡問題。我已經配置NetworkManager使用QoSType ReliableFragmented，但它顯然不工作。我究竟做錯了什麼？附加的NetworkManager組件的代碼和屏幕截圖。儘管將ReliableFragmented通道分配給網絡管理器，但緩衝區仍然太大錯誤

我receving的錯誤是：

NetworkWriter WriteBytes: buffer is too large (1699064) bytes. The maximum buffer size is 64K bytes. 
UnityEngine.Networking.NetworkWriter:WriteBytesFull(Byte[]) 
TextureMessage:Serialize(NetworkWriter) 
UnityEngine.Networking.NetworkServer:SendToAll(Int16, MessageBase) 
Server:SendTexture(Texture2D, String) (at Assets/Scripts/Server.cs:41) 
Server:SendOnButtonPress() (at Assets/Scripts/Server.cs:28) 
UnityEngine.EventSystems.EventSystem:Update()

代碼啓動網絡和串行數據

TextureMessage.cs

using UnityEngine.Networking; 

public class TextureMessage : MessageBase 
{ 
    public byte[] textureBytes; 
    public string message; //Optional 
}

MyMsgType.cs

using UnityEngine.Networking; 

public class MyMsgType 
{ 
    public static short texture = MsgType.Highest + 1; 
}

硒rver.cs

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 
using UnityEngine.Networking; 

public class Server : MonoBehaviour { 

    public Texture2D textureToSend; 
    string messageToSend = "Test Message"; 

    // Use this for initialization 
    void Start() 
    { 
     NetworkManager.singleton.StartHost(); 
     Debug.Log("Server Started."); 
    } 

    public void SendOnButtonPress() 
    { 
     SendTexture(textureToSend, messageToSend); 
    } 

    //Call to send the Texture and a simple string message 
    public void SendTexture(Texture2D texture, string message) 
    { 
     TextureMessage msg = new TextureMessage(); 

     //Convert Texture2D to byte array 

     msg.textureBytes = texture.GetRawTextureData(); 
     msg.message = message; 

     NetworkServer.SendToAll(MyMsgType.texture, msg); 
    } 
}

的可能的複製[NetworkWriter WriteBytes：緩衝器過大（https://stackoverflow.com/questions/46802301/networkwriter-writebytes-buffer-is-too-large） – Draco18s

它是如何工作的內部。

NetworkServer.SendToAll（）：

static public bool SendToAll(short msgType, MessageBase msg) 
{ 
    if (LogFilter.logDev) { Debug.Log("Server.SendToAll msgType:" + msgType); } 
    bool result = true; 

    // this list holds all connections (local and remote) 
    for (int i = 0; i < connections.Count; i++) 
    { 
     NetworkConnection conn = connections[i]; 
     if (conn != null) 
      result &= conn.Send(msgType, msg); 
    } 

    return result; 
}

NetworkConnection公共構造：

public NetworkConnection() 
{ 
    m_Writer = new NetworkWriter(); 
}

NetworkConnection.Send（）：

public virtual bool Send(short msgType, MessageBase msg) 
{ 
    return SendByChannel(msgType, msg, Channels.DefaultReliable); 
}

NetworkConnection.SendByChannel（）：

public virtual bool SendByChannel(short msgType, MessageBase msg, int channelId) 
{ 
    m_Writer.StartMessage(msgType); 
    msg.Serialize(m_Writer); 
    m_Writer.FinishMessage(); 
    return SendWriter(m_Writer, channelId); 
}

如您所見，它使用NetworkWriter來序列化您的消息。 NetworkWriter具有大小爲64Kb的緩衝區。您不能序列化大於64K的對象。所以，你至少有兩種解決方案：

片段的紋理塊大於64K較小的數組/列表，一步連貫發送，一步。
重寫所有網絡代碼。
