[网络协议]使用websocketspython作服务端，unity作客服端完成网络通信

使用websockets,python作服务端，unity作客服端完成网络通信

1：python中使用websockets的建立服务器
参考文章：Python3+WebSockets实现WebSocket通信

#服务端
#coding=utf-8

import asyncio
from encodings import utf_8
from hashlib import new
import websockets
import json


# 接收客户端消息并处理
async def recv_msg(websocket):
    while True:
        # recv_text = await websocket.recv()
        # response_text = f"your submit context: {recv_text}"
        # await websocket.send(response_text)
        async for message in websocket:
            if isinstance(message,bytes):   #如果是bytes类型，则转为str
                message = message.decode()     #string，encode默认编码方式是utf-8
            print(type(message))
            print(message)
            data = json.loads(message)
            print(data['health'])
            print(data['cards'])
            new_data = json.dumps(data,ensure_ascii=False)
            await websocket.send(new_data)  #接收数据后发送回去

# 服务器端主逻辑
# websocket和path是该函数被回调时自动传过来的，不需要自己传
async def main_logic(websocket, path):
    await recv_msg(websocket)

# 把ip换成自己本地的ip 使用ipconfig.exe查看
start_server = websockets.serve(main_logic, '192.168.1.1', 8080)  
# 如果要给被回调的main_logic传递自定义参数，可使用以下形式
# 一、修改回调形式
# import functools
# start_server = websockets.serve(functools.partial(main_logic, other_param="test_value"), '10.10.6.91', 5678)
# 修改被回调函数定义，增加相应参数
# async def main_logic(websocket, path, other_param)


asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

2.unity中建立客户端，并使用自带的JsonUtility包装数据

Unity自带的JsonUtility的使用：unity 通过JsonUtility实现json数据的本地保存和读取

using System;
using System.Collections.Generic;
using System.Net.WebSockets;
using System.Text;
using System.Threading;
using UnityEngine;
using UnityEngine.UI;

public class WebCilent : MonoBehaviour
{
    ClientWebSocket ws;
    CancellationToken ct;
    string rec_str;

    void Start()
    {
        WebSocket();
    }

	//启动客户端
    public async void WebSocket()
    {
        try
        {
            ws = new ClientWebSocket();
            ct = new CancellationToken();
            //添加header
            //ws.Options.SetRequestHeader("X-Token", "eyJhbGciOiJIUzI1N");
            Uri url = new Uri("ws://192.168.1.1:8080");  //ip使用自己电脑的，使用ipconfig.exe查看，要与服务端一致
            await ws.ConnectAsync(url, ct);

            while (true)
            {
                var result = new byte[1024];
                await ws.ReceiveAsync(new ArraySegment<byte>(result), new CancellationToken());//接受数据
                rec_str = Encoding.UTF8.GetString(result, 0, result.Length);
                Debug.Log("rec: "+ rec_str);
                if (rec_str != null)
                {
                    //解析Json
                    Person np = JsonUtility.FromJson<Person>(rec_str);
                    Debug.Log(np.health);
                    Debug.Log(np.ids[0]);
                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }

    public async void sendMsg()
    {
        Person p1 = new Person();
        p1.health = 8000;
        p1.cards = 5;
        p1.ids.Add(1);
        p1.ids.Add(2);
        string jsonStr = JsonUtility.ToJson(p1);
        Debug.Log(jsonStr);

        await ws.SendAsync(new ArraySegment<byte>(Encoding.UTF8.GetBytes(jsonStr)), WebSocketMessageType.Binary, true, ct); //发送数据

    }


}

[Serializable]//序列化
public class Person
{
    public int health;
    public int cards;
    public List<int> ids;
    
    public Person()
    {
        ids = new List<int>();
    }
}
