由于需要在服务端和客户端持续通信，于是在网上找了好久的socket通信工具。刚开始想直接用.net自带的socket通信，后来担心不够稳定健壮，毕竟自己不专业。找来找去觉得supersocket还可以，但是说实话，他们的帮助文档写的真是太烂了，使用也不够简单易懂，折腾了一阵大致明白如何使用。
1，在nuget上引用supersocket.clientengine和supersocket.protobase
2，定义一个filter的类，protobase提供了5种预定义的方式，这里采用第二种，即定义数据头和尾的方式：
TerminatorReceiveFilterBeginEndMarkReceiveFilterFixedHeaderReceiveFilterFixedSizeReceiveFilterCountSpliterReceiveFilter
class MyBeginEndMarkReceiveFilter : BeginEndMarkReceiveFilter<StringPackageInfo>
{
public MyBeginEndMarkReceiveFilter(string begin,string end)
: base(Encoding.UTF8.GetBytes(begin), Encoding.UTF8.GetBytes(end))
{
this.begin = begin;
this.end = end;
}
string begin;
string end;
public override StringPackageInfo ResolvePackage(IBufferStream bufferStream)
{
//获取接收到的完整数据，包括头和尾
var body = bufferStream.ReadString((int)bufferStream.Length, Encoding.ASCII);
//掐头去尾，只返回中间的数据
body = body.Remove(body.Length - end.Length, end.Length);
body = body.Remove(0, begin.Length);
return new StringPackageInfo("", body, new string[] { });
}
}
3，封装一个简单的类。初始化类的时候设置好ip，端口，数据头和尾，然后设置要发送的数据属性data，然后调用startcomm方法开始每秒发送一次请求数据到服务器，订阅接收数据的事件newReceived。如果有需要可以随时更换data的内容，或者调用stopcomm停止发送数据
class socketClient
{
SuperSocket.ClientEngine.EasyClient client;
/// <summary>
/// 定义服务端的ip地址和端口，以及接收数据的头和尾，只有在头和尾之间的数据才算有效数据
/// </summary>
/// <param name="ip">ip地址</param>
/// <param name="port">服务端口</param>
/// <param name="startFilter">数据头</param>
/// <param name="endFilter">数据尾</param>
public socketClient(string ip, int port, string startFilter, string endFilter)
{
this.ip = ip;
this.port = port;
if (!string.IsNullOrEmpty(startFilter)) this.startFilter = startFilter;
if (!string.IsNullOrEmpty(endFilter)) this.endFilter = endFilter;
client = new SuperSocket.ClientEngine.EasyClient();
client.Initialize(new MyBeginEndMarkReceiveFilter(this.startFilter,this.endFilter), onReceived);
}
string ip;
int port;
string startFilter = "!!!";
string endFilter = "###";
bool cycleSend = false;
/// <summary>
/// 要发送到服务端的数据
/// </summary>
public string data { get; set; } = "hello,this is super client
";
public void startComm()
{//开始循环发送数据
cycleSend = true;
System.Threading.Thread _thread = new System.Threading.Thread(sendData);
_thread.IsBackground = true;
_thread.Start();
}
public void sendData()
{//采用线程间隔一秒发送数据，防止界面卡死
while (cycleSend)
{
if (!client.IsConnected)
{
connectToServer(ip, port);
}
if (client.IsConnected)
{
client.Send(Encoding.ASCII.GetBytes("hello,this is super client
"));
}
System.Threading.Thread.Sleep(1000);
}
}
public void stopComm()
{//停止循环发送数据
cycleSend = false;
}
public async void connectToServer(string ip, int port)
{//连接到服务端
var connected = await client.ConnectAsync(new IPEndPoint(IPAddress.Parse(ip), port));
if (connected)
{
//发送连接信息
client.Send(Encoding.ASCII.GetBytes("build connection"));
}
}
public System.EventHandler newReceived;
private void onReceived(StringPackageInfo stringPackageInfo)
{//当读取到数据，触发一个事件，方便外部接收数据
if (newReceived != null)
{
newReceived(stringPackageInfo.Body, new EventArgs());
}
}
}
