Unity3d使用ToLua lua protobuf3配合java neety protobuf3包含源码
博主环境(所有文件都在最底下)：
Unity环境： 2018.1.0b11(64bit) java环境：jdk 1.8， netty环境：netty-all-4.1.16.Final.jar protobuf环境：protobuf-java-3.3.0 python环境：python 2.7网络协议：
使用简单的协议一段完整的数据，前4位byte是数据总长度，向后偏移4位是protoId，用于指向解析的protoBytesJAVA解析数据的地方：
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这个方法的三个参数分别是:(1)复制目标地址,(2)起始位置注意这里的起始位置如果写0,他就是0+你上次读取的位置,(3)复制数据长度
*
*/
}
//这是Utils里面的方法
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处理解析数据和发送加密protobuffer数据的地方：
--接收数据
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)
--测试发送
local personData = {
name = "ilse",
age = 18,
contacts = {
{ name = "alice", phonenumber = 12312341234 },
{ name = "bob", phonenumber = 45645674567 }
}
}
NetWork.SendProtoData(1001,personData)
local datac =0
end
--发送数据
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#处理数据的地方：
文件：GameSoketClient.cs
void OnReceive(byte[] bytes, int length)
{
// Array.Reverse(bytes, 0, length);
//拆包处理分包，协议是最前面4位是总长度，然后偏移4位是protoid，最后是protoData
int resolveLen = 0;
while (resolveLen<length)
{
//数据段大小
int size = BitConverter.ToInt32(bytes, 0);
resolveLen += 4;
//protoId
int protoId = BitConverter.ToInt32(bytes, resolveLen);
resolveLen += 4;
//
int prptoDataSize = size - 4 - 4;
//数据
GameByteBuffer ByteBuffer = GameByteBuffer.getNewInstance();
ByteBuffer.ParseByteBuffer(ref bytes, resolveLen, prptoDataSize, protoId);
ReceiveBytesQueue.Enqueue(ByteBuffer);
resolveLen += prptoDataSize;
}
}
最后我们来看看运行结果：
