Unity3d使用ToLua lua protobuf3配合java neety protobuf3包含源碼

博主環境(所有文件都在最底下)：

Unity環境： 2018.1.0b11(64bit)
java環境：jdk 1.8，
netty環境：netty-all-4.1.16.Final.jar
protobuf環境：protobuf-java-3.3.0
python環境：python 2.7

網絡協議：

使用簡單的協議一段完整的數據，前4位byte是數據總長度，向後偏移4位是protoId，用於指向解析的protoBytes

JAVA解析數據的地方：

文件：NioServerHandler.java
protected void channelRead0(ChannelHandlerContext ctx, Object msg) throws Exception {
		// TODO Auto-generated method stub
	ByteBuf buf=(ByteBuf) msg;
        int totalByteLen = buf.readableBytes();
        int indeLne = 0;
        //解包
        while(totalByteLen>indeLne) {
        	buf.readBytes(dataLenBytes,0,4);
            int totalLen = Utils.bytesToInt(dataLenBytes, 0);
            indeLne += 4;
            buf.readBytes(dataLenBytes,0,4);
            int protoId = Utils.bytesToInt(dataLenBytes, 0);
            indeLne += 4;
            byte[]protoData = new byte[totalLen - 8];
            buf.readBytes(protoData,0,totalLen-8);
            indeLne += totalLen-8;
            Utils.Parse(protoId, protoData);
        }
        /***
         * readBytes這個方法的三個參數分別是:(1)複製目標地址,(2)起始位置注意這裏的起始位置如果寫0,他就是0+你上次讀取的位置,(3)複製數據長度
         * 
         */
}


//這是Utils裏面的方法
 public static void Parse(int protoId,byte[] protoData) {
		try {
			if(protoId == 1001) {
	        	Person person = Person.parseFrom(protoData);
	        	System.out.println("\n解析成功:\n"+person.toString());
	        }
		}catch (Exception e) {
			e.printStackTrace();
		}
	}

Lua處理解析數據和發送加密protobuffer數據的地方：

--接收數據
function NetWork.Receive(data)
    local protoId = data:GetProtoId()
    local luaBytes = data:ReadBuffer()
    local pbName = UNITY.CMD2PB[protoId].name
    local pbData = pb.decode(pbName, luaBytes)
    GameNetManager:sendNetMessage(protoId,pbData)

    --測試發送
    local personData = {
        name = "ilse",
        age = 18,
        contacts = {
            { name = "alice", phonenumber = 12312341234 },
            { name = "bob", phonenumber = 45645674567 }
        }
    }
    NetWork.SendProtoData(1001,personData)
    local datac =0
end
--發送數據
function NetWork.SendProtoData(protoId,data)
    local pbName = UNITY.CMD2PB[protoId].name
    local bytes = assert(pb.encode(pbName, data))
    local ByteBuffer = GameByteBuffer.getNewInstance()
    ByteBuffer:WriteBuffer(protoId,bytes)
    local gameSoketClient = GameSoketClient.GetInstance()
    gameSoketClient:WriteGameByteBuffer(ByteBuffer)
end

C#處理數據的地方：

文件：GameSoketClient.cs
  void OnReceive(byte[] bytes, int length)
    {
        // Array.Reverse(bytes, 0, length);
        //拆包處理分包，協議是最前面4位是總長度，然後偏移4位是protoid，最後是protoData
        int resolveLen = 0;
        while (resolveLen<length)
        {
            //數據段大小
           int size = BitConverter.ToInt32(bytes, 0);
            resolveLen += 4;
            //protoId
            int protoId = BitConverter.ToInt32(bytes, resolveLen);
            resolveLen += 4;
            //
            int prptoDataSize = size - 4 - 4;
            //數據
            GameByteBuffer ByteBuffer = GameByteBuffer.getNewInstance();
            ByteBuffer.ParseByteBuffer(ref bytes, resolveLen, prptoDataSize, protoId);
            ReceiveBytesQueue.Enqueue(ByteBuffer);
            resolveLen += prptoDataSize;
        }
    }

最後我們來看看運行結果：
