收集整理的这篇文章主要介绍了socket传输protobuf字节流的实例介绍,觉得挺不错的,现在分享给大家,也给大家做个参考。上一篇讲到了数据的处理,这一篇主要讲使用多线程收发消息//创建消息数据模型 2//正式项目中,消息的结构一般是消息长度+消息id+消息主体内容 3 public class Message 4 { public IExtensible PRotobuf; public int messageid; 7 } 8 9 public class SocketClientTemp : MonoBehaviour 10 { 11 const int packageMaxLength = 1024; 12 13 Socket mSocket; 14 Thread threadSend; 15 Thread threadRecive; 16 Queuemessage> allMessages = new QueueMessage> (); 17 Queuebyte[]> sendQueue = new Queuebyte[]> (); public bool InIT() 20 { 21 //创建一个socket对象 22 mSocket = new Socket(AddressFamily.internetwork, SocketTyPE.Stream, ProtocolType.Tcp); 23 return SocketConnection("此处是ip", 1111); 24 } 25 26 void Update() 27 { 28 AnalysisMessage(); 29 } 30 31 /// summary> 32 /// 建立服务器连接 33 /// /summary> 34 /// param name="ip"> 服务器的ip地址/param> 35 /// param name="port"> 端口/param> 36 bool SocketConnection(string ip, int port) 37 { 38 try 39 { 40 IPEndPoint ipep = new IPEndPoint(IPAddress.Parse(ip), port); 41 //同步连接服务器,实际使用时推荐使用异步连接,处理方式会在下一篇讲断线重连时讲到 42 mSocket.Connect(ipep); 43 //连接成功后,创建两个线程,分别用于发送和接收消息 44 threadSend = new Thread(new ThreadStart(SendMessage)); 45 threadSend.Start(); 46 threadRecive = new Thread(new ThreadStart(ReceiveMessage)); 47 threadRecive.Start(); 48 return true; 49 } 50 catch (Exception e) 51 { 52 Debug.LOG(e.ToString()); 53 Close(); 54 return false; 55 } } #region ...发送消息 59 /// summary> 60 /// 添加数据到发送队列 61 /// /summary> 62 /// param name="protobufModel"> /param> 63 /// param name="messageId"> /param> 64 public void AddSendMessageQueue(IExtensible protobufModel, int messageId) 65 { 66 sendQueue.Enqueue(BuildPackage(protobufModel, messageId)); 67 } void SendMessage() 70 { 71 //循环获取发送队列中第一个数据,然后发送到服务器 72 while (true) 73 { 74 if (sendQueue.Count == 0) 75 { 76 Thread.Sleep(100); 77 continue; 78 } 79 if (!mSocket.Connected) 80 { 81 Close(); 82 break; 83 } 84 else 85 Send(sendQueue.Peek()); //发送队列中第一条数据 86 } 87 } 88 89 void Send(byte[] bytes) 90 { 91 try 92 { 93 mSocket.Send(bytes, SocketFlags.None); 94 //发送成功后,从发送队列中移除已发送的消息 95 sendQueue.Dequeue(); 96 } 97 catch (SocketException e) 98 { 99 //如果错误码为10035,说明服务器缓存区满了,所以等100毫秒再次发送100 if (e.NativeErrorCode == 10035)101 { 102 Thread.Sleep(100); 103 Send(bytes); 104 } 105 else106 Debug.Log(e.ToString()); 107 } 108 } 109 #endregion110 111 #region ...接收消息112 /// summary> 113 /// 解析收到的消息114 /// /summary> 115 void AnalysisMessage()116 { 117 while (allMessages.Count > 0)118 { 119 int id = allMessages.Dequeue().messageId; 120 switch (id)121 { 122 //根据消息id做不同的处理123 } 124 } 125 } 126 127 /// summary> 128 /// 接收数据129 /// /summary> 130 void ReceiveMessage()131 { 132 while (true)133 { 134 if (!mSocket.Connected)135 break; 136 byte[] recvBytesHead = GetBytesReceive(4); 137 int bodyLength = IPAddress.NetworkToHostOrder(BitConverter.ToInt32(recvbytesHead, 0)); 138 byte[] recvBytesBody = GetBytesReceive(bodyLength); 139 140 byte[] messageId = new byte[4]; 141 Array.Copy(recvBytesBody, 0, messageId, 0, 4); 142 byte[] messageBody = new byte[bodyLength - 4]; 143 Array.Copy(recvBytesBody, 4, messageBody, 0, bodyLength - 4); 144 145 if (BitConverter.IsLiTTLeEndian)146 Array.reverse(messageId); 147 FillAllPackages(BitConverter.ToInt32(messageId, 0), messageBody); 148 } } /// summary> 152 /// 填充接收消息队列153 /// /summary> 154 /// param name="messageId"> /param> 155 /// param name="messageBody"> /param> 156 void FillAllPackages(int messageId, byte[] messageBody)157 { 158 switch (messageId)159 { 160 //根据消息id处理消息,并添加到接收消息队列161 case 1:162 allMessages.Enqueue(new Message() 163 { 164 protobuf = ProtobufSerilizer.DeSerializetestTemp> (messageBody), 165 messageId = messageId 166 } ); 167 break; 168 } 169 } 170 171 /// summary> 172 /// 接收数据并处理173 /// /summary> 174 /// param name="length"> /param> 175 /// returns> /returns> 176 byte[] GetBytesReceive(int length)177 { 178 byte[] recvBytes = new byte[length]; 179 while (length > 0)180 { 181 byte[] receiveBytes = new byte[length packageMaxLength ?

到这里,使用socket处理消息的收发就基本结束了,但是,某些项目为了增强体验,可能还会增加断线重连的功能,这个功能会在下一篇讲到
