- ipv6支持
- 主线程连接
- protobuf
- aes加密
- [] 数据压缩
- 多线程连接
- [] 断线重连
- [] 消息缓存队列
- [] 压力测试
- [] 兼容性测试
第一版已完成，包含如下功能：
- Ipv6支持
- socket连接，收发，断开
- 套接字粘包拆包，消息包的封装，解析
- 消息回调
- 字节消息
- protobuf消息
- aes加密
Tcp socket收发逻辑通用，但是消息包的定义每家各不相同（长度，标识符，时间戳，加密字符..），逻辑设计上也尽量将这部分隔离，方便自定义消息格式。
（如果只需要socket收发逻辑，不需要一整套的消息收发机制，可以只保留工程中的Network文件夹）。
建议采用整套逻辑，套接字的封装解析都不需要做再额外处理。
源码中提供了两种消息结构：字节消息和protobuf消息，可以在unity中定义全局宏定义或者在msgmanager中选择使用哪种方式（默认protobuf）。 源码中提供了两种收发方式：多线程收发和主线程收发，可以在unity中定义全局宏定义或者在clienttcp中选在（默认主线程）。
字节消息结构：
Protobuf消息结构：
如果项目同时支持字节消息和protobuf消息，可以修改成如下结构：
public class Example : MonoBehaviour
{
// Use this for initialization
void Start()
{
//registe bytes msg
MsgManager.Instance.RegisterMsg(110, OnByteMsg);
//you can registe many msg here
//....
//registe protobuf msg
MsgManager.Instance.RegisterMsg(typeof(TestProtobufStruct).FullName, OnProtobufMsg);
//....
//connect(prefer host names)
ClientTcp socket = new ClientTcp();
bool tempIsConnect = socket.Connect("www.google.com", 111);
Debug.Log(tempIsConnect);
// send byte msg
MsgByte tempMsg1 = new MsgByte(110);//110 is proto id
tempMsg1.Write<int>(100);//write msg's body
tempMsg1.Write("hello");//write msg's body
tempMsg1.Flush();//send
//send protobuf msg
TestProtobufStruct testProtobufStruct = new TestProtobufStruct();
testProtobufStruct.x = 100;
testProtobufStruct.y = "hello";
MsgProtobuf tempMsg2 = new MsgProtobuf();
tempMsg2.Write(testProtobufStruct);
tempMsg2.Flush();//send
}
void OnByteMsg(MsgBase param)
{
var test = param as MsgByte;
int temp1 = test.Read<int>(); //100
string temp2 = test.Read<string>(5); //"hello"
Debug.Log(temp1 + temp2);
}
void OnProtobufMsg(MsgBase param)
{
var test = param as MsgProtobuf;
var test2 = test.Read<TestProtobufStruct>();
int temp1 = test2.x;//100
string temp2 = test2.y;//"hello"
Debug.Log(temp1 + temp2);
}
}
public class TestProtobufStruct
{
public int x;
public string y;
}微软提供了很多接口测试当前系统/网络适配器支持哪种ip版本:
Debug.Log(Socket.OSSupportsIPv4);//.net平台过高
Debug.Log(Socket.OSSupportsIPv6);//.net平台过高
Debug.Log(Socket.SupportsIPv4);
Debug.Log(Socket.SupportsIPv6);//微软标记过时api我现在使用的Unity(5.3.4.f1)中mono使用的.net仍然是2.0.50727.1433(Environment.Version),第一和第二条按照msdn说明都是基于现有.net平台(.net4.5+),在unity中执行中肯定会异常,但是在调用的时候发现第一条异常,第二条执行正常,仔细查找mono兼容api发现:
unity对第二第三第四都提供支持,唯独不支持第一条.第四条被标记成过时api,下面只说明第二第三条.
Tip: 关于stackoverfollow中有人测试说第二条在android上测试异常看来是谬传了.
按照接口声明,第二条和第三条在unity中正常使用,并非在android上抛出异常.
再说在unity中支持ipv6,官方说明:
说的很明确,推荐域名,然后通过addressfamily选择合适的ipv4或ipv6,下面就通过tcpclient具体处理ipv6支持.
if (Socket.OSSupportsIPv6)
client = new TcpClient(AddressFamily.InterNetworkV6);
else
client = new TcpClient(AddressFamily.InterNetwork);源码中提供aes加密，需要传入32位密钥，消息传输过程中加密解密会消耗性能，如果对保密要求不严格可以使用简单的移位实现。
