在SuperSocket中不激活AppServer.NewRequestReceived事件

标签: c# supersocket.net

我创建了一个服务器,只要收到新请求就打印出一行:

var server = new AppServer();
if (!server.Setup(2012) || !server.Start()) {
    return;
}
server.NewSessionConnected += (session) => Console.WriteLine("new connection");
server.NewRequestReceived += (session, requestInfo) => Console.WriteLine("new request");

我从netcat连接到它:

C:\Users\sashoalm>nc localhost 2012
test
test
^C
C:\Users\sashoalm>

它打印new connection但从不打印new request,尽管从netcat键入2行。我知道netcat每次输入一个完整的行时都会将文本发送到服务器(这就是netcat的工作方式)。

编辑:我发现了另一个(措辞不太好)未回答的问题可能会问同样的事情 - How to send data to server using supersocket library,但我不完全确定这是否是同一个问题。那个人试图从代码中发送数据。

另一个相关问题 - C# SuperSocket without protocol。他们谈论那里的协议。 SuperSocket中没有指定默认协议吗?是HTTP还是别的什么?

使用下面的简单客户端,基于此MSDN Sample

    static void Main(string[] args)
    {
        IPHostEntry ipHostInfo = Dns.Resolve("localhost");
        IPAddress ipAddress = ipHostInfo.AddressList[0];
        IPEndPoint remoteEP = new IPEndPoint(ipAddress, 2012);

        Socket sender = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        sender.Connect(remoteEP);

        Console.WriteLine("Socket connected to {0}", sender.RemoteEndPoint.ToString());

        List<string> list = new List<string>
            {
                "Test1\r\n",
                "Test2",
                "Test3\r\n",
                "Test4\r\n",
                "Test5\r\n",
                "Test6\r\n",
                "Test7",
                "Test8\r\n",
                "Test9\r\n",
            };

        foreach (string s in list)
            sender.Send(Encoding.ASCII.GetBytes(s));

        sender.Shutdown(SocketShutdown.Both);
        sender.Close();
    }

并使用稍微修改过的服务器版本:

    static void Main(string[] args)
    {
        var server = new AppServer();

        if (!server.Setup(2012) || !server.Start())
        {
            return;
        }

        server.NewSessionConnected += (session) => Console.WriteLine("new connection");
        server.NewRequestReceived += (session, requestInfo) => Console.WriteLine("new request: Key={0}", requestInfo.Key);

        Console.WriteLine("Press ENTER to exit....");
        Console.ReadLine();
    }

显示使用或不使用\r\n作为请求的终止符的效果:

Press ENTER to exit.... 
new connection 
new request: Key=Test1 
new request: Key=Test2Test3 
new request: Key=Test4 
new request: Key=Test5
new request: Key=Test6 
new request: Key=Test7Test8 
new request: Key=Test9

没有终结符的请求与下一个请求连接,直到找到终结符。
