Question

我正在尝试用Unity3D编写一个程序，可以从Python应用程序接收和可视化数据：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Net;
using System.Net.Sockets;
using System.Linq;
using System;

public class Visualizer : MonoBehaviour {


    TcpListener listener;

    private Socket client = null;

    private int i = 0;
    const int byteCount = 1000;

    private const int recvPort = 11000;


    static private bool receiverConnected;    
    static private bool receiverReady;


    //TODO: set max message size somehow intelligently
    private byte[] bytes = new byte[byteCount];

    void Start() {



        receiverConnected = false;
        receiverReady = false;

        IPAddress localAddr = IPAddress.Parse("127.0.0.1"); //always locally
        listener = new TcpListener(localAddr, recvPort);        
        listener.Start();       






    }

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

        if (listener.Pending())
        {            
            client = listener.AcceptSocket();
            receiverConnected = true;

        }



        if (receiverConnected)
        {


            try
            {
                int bytesRec;
                byte[] allBytes = new byte[byteCount];

                bytesRec = client.Receive(allBytes);





                    if (bytesRec == 0)
                    {
                        client.Close();
                        client.Disconnect(false);



                    receiverReady = false;
                    receiverConnected = false;
                }
                else { 

                    bytes = allBytes.Take(bytesRec).ToArray();
                    receiverReady = true;
                }


            catch (Exception e)
            {

                Debug.Log("Exception in receiving and rendering data");
            }
        }


        //now process:

        if (receiverConnected && receiverReady)
        {
         //DO STUFF

        }
    }


}

在Python方面，我的程序从以下内容开始：

TCP_IP = '127.0.0.1'
TCP_PORT = 11000
BUFFER_SIZE = 1000           
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))

虽然这在一开始可以正常工作，但在我关闭python应用程序并重新启动它几次之后，s.connect((TCP_IP, TCP_PORT))开始挂起，程序就再也不会继续了。我想我在处理这些联系的过程中肯定有问题。如何只修改它一点点，以便更优雅地处理关闭和重新打开python端连接请求

Answer 1

将数据传递给花药活动

 ArrayList<Animal> animals = new ArrayList<Animal>();
//fill your list with animals here

i.putExtra("animals", animals);

收到这些数据

ArrayList<Animal> animals = (ArrayList<Animal>) getIntent()
                        .getSerializableExtra("animals");

Answer 2

如果您想要传递ArrayList<Form>，那么使用getParcelableArrayListExtra进行传递
通常，请遵循以下步骤：

• 使你的Form类正确implement Parcelable

• 在活动发送意图中：

  // ArrayList<Form> myList - data to send; intent.putParcelableArrayListExtra("geopoints", myList);

• 在接收活动中：

  ArrayList<Form> myReceivedList = getIntent().getParcelableArrayListExtra("geopoints");

别忘了空/健全检查
