unity 如何从 Matlab 套接字读取数据

Question

我想统一做一些模拟。对于我的项目，我想使用 Matlab 作为处理层。所以我想使用套接字进行通信。

这里 Matlab 是服务器，代码如下：

clc
clear all
tcpipServer = tcpip('0.0.0.0',55000,'NetworkRole','Server');
while(1)
    b=1
data = membrane(1);
b=2
s = whos('data');
b=3
set(tcpipServer,'OutputBufferSize',s.bytes);
b=4
fopen(tcpipServer);
b=5
fwrite(tcpipServer,'hi');
fclose(tcpipServer);
d=6
end

我使用 1,2,.. 来显示过程

我统一使用此代码

using UnityEngine;
using System.Collections;
using System.Net;
using System.Net.Sockets;
using System;
using System.IO;


public class Socket : MonoBehaviour {

    // Use this for initialization

    internal Boolean socketReady = false;
    TcpClient mySocket;
    NetworkStream theStream;
    StreamWriter theWriter;
    StreamReader theReader;
    String Host = "localhost";
    Int32 Port = 55000;


    void Start () {
        setupSocket ();
        Debug.Log ("socket is set up");
        Debug.Log (readSocket()+" is the message");
        closeSocket ();
        Debug.Log ("Socket is closed");
    }

    // Update is called once per frame
    void Update () {

    }

    public void setupSocket() {
        try {
            mySocket = new TcpClient(Host, Port);
            theStream = mySocket.GetStream();
            theWriter = new StreamWriter(theStream);
            theReader = new StreamReader(theStream);
            socketReady = true;
        }
        catch (Exception e) {
            Debug.Log("Socket error: " + e);
        }
    }

    public String readSocket() {
        if (!socketReady)
            return "";
        if (theStream.DataAvailable)
            return theReader.ReadLine();
        return "";
    }


    public void closeSocket() {
        if (!socketReady)
            return;
        theWriter.Close();
        theReader.Close();
        mySocket.Close();
        socketReady = false;
    }
}

首先我启动 Matlab，然后我玩统一。结果是，连接正常，但我无法读取 Matlab 发送的数据

这是我在 Matlab 中得到的

b =

     1


b =

     2


b =

     3


b =

     4


b =

     5


d =

     6


b =

     1


b =

     2


b =

     3


b =

     4

最后这就是我团结起来的结果

socket is set up

is the message

Socket is closed

预期结果是

socket is set up

hi is the message

Socket is closed

我不知道如何读取数据以及如何实现它。

谢谢

这是最简单和完整的解决方案。 在这个解决方案中，每个 matlab 或 unity 都可以用作服务器或客户端。

首先，Matlab作为服务器，unity作为客户端

ma​​tlab 代码

clc
clear all
tcpipServer = tcpip('0.0.0.0',55000,'NetworkRole','Server');
while(1)
data = membrane(1);
fopen(tcpipServer);
rawData = fread(tcpipServer,14,'char');
for i=1:14
   rawwData(i)= char(rawData(i));
end
fclose(tcpipServer);
end

Unity C# 代码

using System.Collections;
using System.Net;
using System.Net.Sockets;
using System;
using System.IO;


public class Socket : MonoBehaviour {

    // Use this for initialization

    internal Boolean socketReady = false;
    TcpClient mySocket;
    NetworkStream theStream;
    StreamWriter theWriter;
    StreamReader theReader;
    String Host = "localhost";
    Int32 Port = 55000;


    void Start () {


        setupSocket ();
        Debug.Log ("socket is set up");
    }

    // Update is called once per frame
    void Update () {

    }

    public void setupSocket() {
        try {

            mySocket = new TcpClient(Host, Port);
            theStream = mySocket.GetStream();
            theWriter = new StreamWriter(theStream);
            socketReady = true;
            writeSocket("yah!! it works");
            Debug.Log ("socket is sent");

        }
        catch (Exception e) {
            Debug.Log("Socket error: " + e);
        }
    }
}

现在反之亦然，unity 作为服务器，Matlab 作为客户端

Unity C# 代码

using UnityEngine;
using System.Collections;
using System.Net;
using System.Net.Sockets;
using System.Linq;
using System;
using System.IO;
using System.Text;


public class readSocket : MonoBehaviour {

    // Use this for initialization
    TcpListener listener;
    String msg;


    void Start () {
        listener=new TcpListener (55001);
        listener.Start ();
        print ("is listening");
    }
    // Update is called once per frame
    void Update () {
        if (!listener.Pending ())
        {
        } 
        else 
        {
            print ("socket comes");
            TcpClient client = listener.AcceptTcpClient ();
            NetworkStream ns = client.GetStream ();
            StreamReader reader = new StreamReader (ns);
            msg = reader.ReadToEnd();
            print (msg);

        }
    }
}

Matlab 代码

clc
clear all
tcpipClient = tcpip('127.0.0.1',55001,'NetworkRole','Client');
set(tcpipClient,'Timeout',30);
fopen(tcpipClient);
a='yah!! we could make it';
fwrite(tcpipClient,a);
fclose(tcpipClient);

在每个实现中，服务器应先于客户端运行，否则您将收到以下错误

连接被拒绝：在Matlab或远程机器中统一主动拒绝连接
