与多个客户端TCP服务器 [英] TCP server with multiple Clients
问题描述
我工作的TCP服务器/客户端应用程序。
我的问题是：
我的服务器应用程序启动一个新的线程，并阻止它，直到连接被接受
该listenforClient方法
但我怎么能管理连接当多个客户端连接到我的服务器，他们要求不同的东西的同时如何管理客户端1获取信息的需求，并同客户端2。
它的多线程，因此多个客户端可以连接，但我怎么可以处理该请求。
我不想把一切都在1比的方法会是什么。
由于提前
私人无效serverstart（）
{
this.tcplistener =新的TcpListener（IPAddress.Any，49151）;
this.listenThread =新主题（新的ThreadStart（ListenForClients））;
this.listenThread.Start（）;
} 私人无效ListenForClients（）
{
this.tcplistener.Start（）; 而（真）
{
//块，直到客户端已连接到服务器
TcpClient的客户= this.tcplistener.AcceptTcpClient（）;
//这里是：第一，发送hello客户端的消息
//
////////////////////////////////////////////////// / //创建一个线程来处理通信
//与连接的客户端
螺纹clientThread =新主题（新ParameterizedThreadStart（HandleClientComm））; clientThread.Start（客户端）;
}
} 私人无效HandleClientComm（对象客户端）
{
的TcpClient的TcpClient =（TcpClient的）客户端;
的NetworkStream clientStream = tcpClient.GetStream（）; 字节[]消息=新的字节[4096];
INT读取动作; 而（真）
{
读取动作= 0; 尝试
{
//阻塞，直到客户端发送一个消息
读取动作= clientStream.Read（消息，0，4096）;
}
抓住
{
//套接字错误发生
打破;
} 如果（读取动作== 0）
{
//客户端已与服务器断开连接
打破;
} //消息已被成功地接收到
ASCIIEncoding EN codeR =新ASCIIEncoding（）; bufferincmessage = EN coder.GetString（消息0，读取动作）;
如果（System.Text.RegularEx pressions.Regex.IsMatch（bufferincmessage，Properties.Settings.Default.REQLogin，System.Text.RegularEx pressions.RegexOptions.IgnoreCase））
{
bufferincmessageresult = bufferincmessage.Split（'^'）;
nickname_Cl = bufferincmessageresult [1];
password_Cl = bufferincmessageresult [2];
getuserdata_db（）;
登录（）; 字节[]缓冲= EN coder.GetBytes（inlogmessage）; clientStream.Write（缓冲液，0，buffer.Length）;
clientStream.Flush（）;
}
}
}
您客户端将在不同的线程调度，所以他们不会相交。
你只需要添加类似您的信息将被处理DispatchMethod。
使用System.Text.RegularEx pressions;
...如果（Regex.IsMatch（bufferincmessage，Properties.Settings.Default.REQLogin，RegexOptions.IgnoreCase））
{
...
}
否则，如果（Regex.IsMatch（bufferincmessage，/ *你的一些的Command * / RegexOptions.IgnoreCase））
{
...
}
否则，如果（Regex.IsMatch（bufferincmessage，/ *你的一些的Command * / RegexOptions.IgnoreCase））
{
...
}
I am working on TCP server/client application.
My question is:
My server application starts a new thread and blocks it until connection is accepted the listenforClient method
But how can I manage the connections when multiple Clients are connected to my server and they request different things at the same time how can i manage that client 1 gets info its need and same for client 2.
It's multithreaded, so multiple Clients can connect but how can i process the request. I don't want to put everything in 1 method what than would.
Thanks in Advance
private void serverstart()
{
this.tcplistener = new TcpListener(IPAddress.Any, 49151);
this.listenThread = new Thread(new ThreadStart(ListenForClients));
this.listenThread.Start();
}
private void ListenForClients()
{
this.tcplistener.Start();
while (true)
{
//blocks until a client has connected to the server
TcpClient client = this.tcplistener.AcceptTcpClient();
// here was first an message that send hello client
//
///////////////////////////////////////////////////
//create a thread to handle communication
//with connected client
Thread clientThread = new Thread(new ParameterizedThreadStart(HandleClientComm));
clientThread.Start(client);
}
}
private void HandleClientComm(object client)
{
TcpClient tcpClient = (TcpClient)client;
NetworkStream clientStream = tcpClient.GetStream();
byte[] message = new byte[4096];
int bytesRead;
while (true)
{
bytesRead = 0;
try
{
//blocks until a client sends a message
bytesRead = clientStream.Read(message, 0, 4096);
}
catch
{
//a socket error has occured
break;
}
if (bytesRead == 0)
{
//the client has disconnected from the server
break;
}
//message has successfully been received
ASCIIEncoding encoder = new ASCIIEncoding();
bufferincmessage = encoder.GetString(message, 0, bytesRead);
if (System.Text.RegularExpressions.Regex.IsMatch(bufferincmessage, Properties.Settings.Default.REQLogin, System.Text.RegularExpressions.RegexOptions.IgnoreCase))
{
bufferincmessageresult = bufferincmessage.Split('^');
nickname_Cl = bufferincmessageresult[1];
password_Cl = bufferincmessageresult[2];
getuserdata_db();
login();
byte[] buffer = encoder.GetBytes(inlogmessage);
clientStream.Write(buffer, 0, buffer.Length);
clientStream.Flush();
}
}
}
Your client will be dispatched in different threads, so they will not intersect. You just need to add something like "DispatchMethod" where your messages will be processed.
using System.Text.RegularExpressions;
...
if (Regex.IsMatch(bufferincmessage, Properties.Settings.Default.REQLogin, RegexOptions.IgnoreCase))
{
...
}
else if (Regex.IsMatch(bufferincmessage, /*some of your command1*/, RegexOptions.IgnoreCase))
{
...
}
else if (Regex.IsMatch(bufferincmessage, /*some of your command1*/, RegexOptions.IgnoreCase))
{
...
}
