服务端架构

总体架构

单进程服务端结构。

• 处理客户端的消息
  客户端与服务端通过TCP连接并传递数据。
• 存储玩家数据
  MySQL数据库保存玩家数据。

模块划分

• 网络底层
  处理网络连接的底层模块，有粘包半包、协议解析等功能。

1. 消息处理
   游戏逻辑层，比如收到MsgMove协议，服务端会记录玩家坐标，然后广播。
2. 事件处理
   玩家上线和下线等。上线，初始化；下线，数据记录。

• 数据库底层
  提供保存玩家数据、读取玩家数据、注册、检验用户名密码等功能，封装服务端和数据库的交互。

1. 存储结构
   指定保存数据，比如金币、等级、经验、文本。

游戏流程

• 连接阶段
  客户端调用Connect连接服务端。连通后，客户端发送登录协议（含用户名、密码等信息），检验通过后，服务端从数据库获取该角色数据，登录成功。
• 交互阶段
  双端互通协议，MsgMove、MsgAttack等。
• 登出阶段
  玩家下线，服务端保存数据。定时保存玩家数据（每隔几分钟），相对安全，能够挽回部分突然挂掉在线玩家数据，频繁写数据库，性能较差；玩家下线时保存数据。

状态	说明
连接但未登录	Connect连接，角色未关联，需输入账号密码，服务端验证后从数据库读取角色数据并关联
登录成功	连接和角色关联后，玩家可操作游戏角色，如移动、攻击等

Json编码解码

类的序列化。

• 服务端与客户端交互需要编码和解码Json协议。
• PlayerData（存储玩家数据，金币、等级等）类对象需要需要序列化为Json字符串存入数据库。

添加协议文件

net网络模块，proto协议文件。

引用System.web.Extensions

修改MsgBase类

using System;
using System.Linq;
using System.Web.Script.Serialization;public class MsgBase {public string protoName = "null";//编码器static JavaScriptSerializer Js = new JavaScriptSerializer();//编码public static byte[] Encode(MsgBase msgBase){string s = Js.Serialize(msgBase); return System.Text.Encoding.UTF8.GetBytes(s);}//解码public static MsgBase Decode(string protoName, byte[] bytes, int offset, int count){string s = System.Text.Encoding.UTF8.GetString(bytes, offset, count);MsgBase msgBase = (MsgBase)Js.Deserialize(s, Type.GetType(protoName));return msgBase;}//编码协议名（2字节长度+字符串）public static byte[] EncodeName(MsgBase msgBase){//名字bytes和长度byte[] nameBytes = System.Text.Encoding.UTF8.GetBytes(msgBase.protoName);Int16 len = (Int16)nameBytes.Length;//申请bytes数值byte[] bytes = new byte[2+len];//组装2字节的长度信息bytes[0] = (byte)(len%256);bytes[1] = (byte)(len/256);//组装名字bytesArray.Copy(nameBytes, 0, bytes, 2, len);return bytes;}//解码协议名（2字节长度+字符串）public static string DecodeName(byte[] bytes, int offset, out int count){count = 0;//必须大于2字节if(offset + 2 > bytes.Length){return "";}//读取长度Int16 len = (Int16)((bytes[offset+1] << 8 )| bytes[offset] );//长度必须足够if(offset + 2 + len > bytes.Length){return "";}//解析count = 2+len;string name = System.Text.Encoding.UTF8.GetString(bytes, offset+2, len);return name;}
}

测试

using System;class Test {public static void Main(string[] args) {MsgMove msgMove = new MsgMove();msgMove.x = 100;msgMove.y = -20;byte[] bytes = MsgBase.Encode(msgMove);string s = System.Text.Encoding.UTF8.GetString(bytes);Console.WriteLine(s);s = "{\"protoName\":\"MsgMove\",\"x\":100,\"y\":-20,\"z\":0}";bytes = System.Text.Encoding.UTF8.GetBytes(s);msgMove = (MsgMove) MsgBase.Decode("MsgMove", bytes, 0, bytes.length);Console.WriteLine(msgMove.x);Console.WriteLine(msgMove.y);Console.WriteLine(msgMove.z);}
}

网络模块

整体结构

1. 网络管理器NetManager，处理select多路复用。
2. ClientState类，定义客户端信息。
3. MsgHandler类，处理网络消息，根据消息类型，分拆到多个文件中（BattleMsgHandler.cs处理战斗相关协议，SysMsgHandler处理MsgPing，MsgPong等系统协议）。
4. 事件处理类EventHandler。

程序引入玩家列表，玩家登录后clientState与player对象关联。通过clientState是否持有player对象判断客户端状态。

logic，代表游戏逻辑部分。

ClientState

客户端信息，一个客户端连接对应一个ClientState对象。

using System.Net.Sockets;public class ClientState
{public Socket socket; public ByteArray readBuff = new ByteArray(); //Pingpublic long lastPingTime = 0;//玩家public Player player;
}

开启监听和多路复用

using System;
using System.Net;
using System.Net.Sockets;
using System.Collections.Generic;
using System.Reflection;
using System.Linq;class NetManager {//监听Socketpublic static Socket listenfd;//客户端Socket及状态信息public static Dictionary<Socket, ClientState> clients = new Dictionary<Socket, ClientState>();//Select的检查列表static List<Socket> checkRead = new List<Socket>();//ping间隔public static long pingInterval = 30;
}

public static void StartLoop(int listenPort) {//Socketlistenfd = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//BindIPAddress ipAdr = IPAddress.Parse("0.0.0.0");IPEndPoint ipEp = new IPEndPoint(ipAdr, listenPort);listenfd.Bind(ipEp);//Listenlistenfd.Listen(0);Console.WriteLine("[服务器]启动成功");//循环while(true){ResetCheckRead();  //重置checkReadSocket.Select(checkRead, null, null, 1000);//阻塞1秒，直到可读//检查可读对象for(int i = checkRead.Count-1; i>=0; i--){Socket s = checkRead[i];if(s == listenfd){ReadListenfd(s);}else{ReadClientfd(s);}}//超时Timer();}
}

//填充checkRead列表
public static void ResetCheckRead(){checkRead.Clear();checkRead.Add(listenfd); foreach(ClientState s in clients.Values){checkRead.Add(s.socket);}
}

处理监听消息

//读取Listenfd
public static void ReadListenfd(Socket listenfd){try{Socket clientfd = listenfd.Accept();//访问套接字时出错、Socket已经关闭等情形下会抛出异常Console.WriteLine("[Accept]" + clientfd.RemoteEndPoint.ToString());ClientState state = new ClientState();state.socket = clientfd;state.lastPingTime = GetTimeStamp();clients.Add(clientfd, state);}catch(SocketException ex){Console.WriteLine("[Accept fail]" + ex.ToString());}
}

处理客户端消息

//读取Clientfd
public static void ReadClientfd(Socket clientfd){ClientState state = clients[clientfd];ByteArray readBuff = state.readBuff;//接收int count = 0;//缓冲区不够，清除，若依旧不够，只能返回//缓冲区长度只有1024，单条协议超过缓冲区长度时会发生错误，根据需要调整长度if(readBuff.remain <=0){OnReceiveData(state);readBuff.MoveBytes();};if(readBuff.remain <=0){Console.WriteLine("Receive fail , maybe msg length > buff capacity");Close(state);return;}try{count = clientfd.Receive(readBuff.bytes, readBuff.writeIdx, readBuff.remain, 0);}catch(SocketException ex){//发生异常，连接失效，Close。Console.WriteLine("Receive SocketException " + ex.ToString());Close(state);return;}//客户端关闭if(count <= 0){//客户端主动断开连接，服务端收到长度为0数据，Close。Console.WriteLine("Socket Close " + clientfd.RemoteEndPoint.ToString());Close(state);return;}//消息处理readBuff.writeIdx += count;//处理二进制消息OnReceiveData(state);//处理粘包分包问题//移动缓冲区readBuff.CheckAndMoveBytes();
}

关闭连接

1. 分发OnDisconnect事件，让程序可以在玩家掉线时做些处理；
2. 调用socket.Close关闭连接；
3. 将客户端状态state移除clients列表。

//关闭连接
public static void Close(ClientState state){//消息分发MethodInfo mei =  typeof(EventHandler).GetMethod("OnDisconnect");object[] ob = {state};mei.Invoke(null, ob);//关闭state.socket.Close();clients.Remove(state.socket);
}

处理协议

//数据处理
public static void OnReceiveData(ClientState state){ByteArray readBuff = state.readBuff;//消息长度if(readBuff.length <= 2) {return;}Int16 bodyLength = readBuff.ReadInt16();//消息体if(readBuff.length < bodyLength){return;}//解析协议名int nameCount = 0;string protoName = MsgBase.DecodeName(readBuff.bytes, readBuff.readIdx, out nameCount);if(protoName == ""){Console.WriteLine("OnReceiveData MsgBase.DecodeName fail");Close(state);return;}readBuff.readIdx += nameCount;//解析协议体int bodyCount = bodyLength - nameCount;MsgBase msgBase = MsgBase.Decode(protoName, readBuff.bytes, readBuff.readIdx, bodyCount);readBuff.readIdx += bodyCount;readBuff.CheckAndMoveBytes();//分发消息MethodInfo mi =  typeof(MsgHandler).GetMethod(protoName);object[] o = {state, msgBase};Console.WriteLine("[Receive]" + protoName);if(mi != null){mi.Invoke(null, o);}else{Console.WriteLine("OnReceiveData Invoke fail " + protoName);}//继续读取消息if(readBuff.length > 2){OnReceiveData(state);}
}

Timer

//定时器
static void Timer(){//消息分发MethodInfo mei =  typeof(EventHandler).GetMethod("OnTimer");object[] ob = {};mei.Invoke(null, ob);
}

发送协议

//发送
public static void Send(ClientState cs, MsgBase msg){//状态判断if(cs == null){return;}if(!cs.socket.Connected){return;}//数据编码byte[] nameBytes = MsgBase.EncodeName(msg);byte[] bodyBytes = MsgBase.Encode(msg);int len = nameBytes.Length + bodyBytes.Length;byte[] sendBytes = new byte[2+len];//组装长度sendBytes[0] = (byte)(len%256);sendBytes[1] = (byte)(len/256);//组装名字Array.Copy(nameBytes, 0, sendBytes, 2, nameBytes.Length);//组装消息体Array.Copy(bodyBytes, 0, sendBytes, 2+nameBytes.Length, bodyBytes.Length);//为简化代码，不设置回调try{cs.socket.BeginSend(sendBytes,0, sendBytes.Length, 0, null, null);}catch(SocketException ex){Console.WriteLine("Socket Close on BeginSend" + ex.ToString()); } 
}

测试

1. 协议处理

BattleMsgHandler.cs

using System;public partial class MsgHandler {public static void MsgMove(ClientState c, MsgBase msgBase){MsgMove msgMove = (MsgMove)msgBase;Console.WriteLine(msgMove.x);msgMove.x++;NetManager.Send(c, msgMove);}
}

SysMsgHandler.cs

using System;public partial class MsgHandler {public static void MsgPing(ClientState c, MsgBase msgBase){Console.WriteLine("MsgPing");c.lastPingTime = NetManager.GetTimeStamp();MsgPong msgPong = new MsgPong();NetManager.Send(c, msgPong);}
}

partial表明类是局部类型，允许将一个类、结构或接口分成几个部分，分别实现在几个不同的cs文件中。

2. 事件处理

using System;public partial class EventHandler {public static void OnDisconnect(ClientState c){Console.WriteLine("Close");}public static void OnTimer(){}
}

3. 启动网络监听

using System;class Server {public static void Main(strin[] args) {NetManager.StartLoop(8888);}
}

4. 开始测试

客户端发送MsgMove协议。

心跳机制

lastPingTime

using System.Net.Sockets;public class ClientState
{public Socket socket; public ByteArray readBuff = new ByteArray(); //Pingpublic long lastPingTime = 0;//玩家public Player player;
}

class NetManager {public static long pingInterval = 30;
}

时间戳

1970年1月1日零点到现在的秒数。

//获取时间戳
public static long GetTimeStamp() {TimeSpan ts = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0);return Convert.ToInt64(ts.TotalSeconds);
}

回应MsgPing协议

using System;public partial class MsgHandler {public static void MsgPing(ClientState c, MsgBase msgBase){Console.WriteLine("MsgPing");c.lastPingTime = NetManager.GetTimeStamp();MsgPong msgPong = new MsgPong();NetManager.Send(c, msgPong);}
}

超时处理

服务端长时间未收到MsgPing时，认为连接已经断开。

public static void OnTimer(){CheckPing();
}//Ping检查
public static void CheckPing(){//现在的时间戳long timeNow = NetManager.GetTimeStamp();//遍历，删除foreach(ClientState s in NetManager.clients.Values){if(timeNow - s.lastPingTime > NetManager.pingInterval*4){Console.WriteLine("Ping Close " + s.socket.RemoteEndPoint.ToString());NetManager.Close(s);return;}}
}

测试程序

设置服务端pingInterval值为2。

玩家的数据结构

完整的ClientState

using System.Net.Sockets;public class ClientState {public Socket socket; public ByteArray readBuff = new ByteArray(); //Pingpublic long lastPingTime = 0;//玩家public Player player;
}

PlayerData

public class PlayerData{//金币public int coin = 0;//记事本public string text = "new text";
}

Player

using System;public class Player {//idpublic string id = "";//指向ClientStatepublic ClientState state;//构造函数public Player(ClientState state){this.state = state;}//临时数据，如：坐标public int x; public int y; public int z;//数据库数据public PlayerData data;//发送信息public void Send(MsgBase msgBase){NetManager.Send(state, msgBase);}
}

PlayerManager

using System;
using System.Collections.Generic;public class PlayerManager {//玩家列表static Dictionary<string, Player> players = new Dictionary<string, Player>();//玩家是否在线public static bool IsOnline(string id){return players.ContainsKey(id);}//获取玩家public static Player GetPlayer(string id){return players[id];}//添加玩家public static void AddPlayer(string id, Player player){players.Add(id, player);}//删除玩家public static void RemovePlayer(string id){players.Remove(id);}
}

数据库模块

连接数据库

DbManager.cs

using System;
using MySql.Data.MySqlClient;
using System.Text.RegularExpressions;
using System.Web.Script.Serialization;public class DbManager {public static MySqlConnection mysql;static JavaScriptSerializer Js = new JavaScriptSerializer();//连接mysql数据库public static bool Connect(string db, string ip, int port, string user, string pw) {//创建MySqlConnection对象mysql = new MySqlConnection();//连接参数string s = string.Format("Database={0};Data Source={1}; port={2};User Id={3}; Password={4}", db, ip, port, user, pw);mysql.ConnectionString = s;//连接try{mysql.Open();Console.WriteLine("[数据库]connect succ ");return true;}catch (Exception e){Console.WriteLine("[数据库]connect fail, " + e.Message);return false;}}
}

using System;class Test {public static void Main(string[] args) {DbManager.Connect("game", "127.0.0.1", 3306, "root", "");}
}

csc DbManager.cs Test.cs -reference:MySql.Data.dll

防止SQL注入

SQL注入，指通过输入请求，把SQL命令插入到SQL语句中，以达到欺骗服务器执行恶意SQL命令的目的。

string sql = "select * from player where id = " + id;

若

id = "xiaoming; delete * from player;";

则

sql = "select * from player where id = xiaoming; delete * from player;";

在拼装SQL语句前，对用户输入的字符串进行安全性检测（含有逗号、分号等特殊字符的字符串判定为不安全字符串），能够有效地防止SQL注入。

using System.Text.RegularExpressions;//判定安全字符串
private static bool IsSafeString(string str) {return !Regex.IsMatch(str, @"[-|;|,|\/|\(|\)|\[|\]|\}|\{|%|@|\*|!|\']");
}

IsAccountExist

//是否存在该用户
public static bool IsAccountExist(string id) {//防sql注入if (!DbManager.IsSafeString(id)){return false;}//sql语句string s = string.Format("select * from account where id='{0}';", id);  //查询try {MySqlCommand cmd = new MySqlCommand(s, mysql); MySqlDataReader dataReader = cmd.ExecuteReader(); bool hasRows = dataReader.HasRows;dataReader.Close();return !hasRows;}catch(Exception e){Console.WriteLine("[数据库] IsSafeString err, " + e.Message);return false;}
}

Register

//注册
public static bool Register(string id, string pw) {//防sql注入if(!DbManager.IsSafeString(id)){Console.WriteLine("[数据库] Register fail, id not safe");return false;}if(!DbManager.IsSafeString(pw)){Console.WriteLine("[数据库] Register fail, pw not safe");return false;}//能否注册if(!IsAccountExist(id)) {Console.WriteLine("[数据库] Register fail, id exist");return false;}//写入数据库User表string sql = string.Format("insert into account set id ='{0}' ,pw ='{1}';", id, pw);try{MySqlCommand cmd = new MySqlCommand(sql, mysql);cmd.ExecuteNonQuery();return true;}catch(Exception e) {Console.WriteLine("[数据库] Register fail " + e.Message);return false;}
}

明文密码应该加密（md5加密等）存入数据库。
