python中websockets与主线程传递参数

一、子线程创建websockets服务端接收客户端数据

二、主线程内启动子线程接收并处理数据

一、子线程创建websockets服务端接收客户端数据并存入队列

发送的消息客户端与服务端统一，多种消息加入判断的标签

服务端：web_server.py

import asyncio
import json
import base64
import queue
import threading
import time
import cv2
import moment
import numpy as np
import requests
import websocketsclass WebServer:def __init__(self, host, port):self.host = hostself.port = portself.msg_queue = queue.Queue()self.clients = []self.flag = Trueasync def echo(self, websocket, path):client_ip, client_port = websocket.remote_addressself.clients.append(websocket)while True:try:# 在这里处理收到的消息# async for recv_text in websocket:recv_text = await websocket.recv()with open("aa.txt","w") as f:f.write(recv_text)data = json.loads(recv_text)#if type(data) is not dict: # 判断数据#    continueself.msg_queue.put(res)except websockets.ConnectionClosed:print("ConnectionClosed...", websocket.remote_address)  # 链接断开self.clients.remove(websocket)breakexcept websockets.InvalidState:print("InvalidState...", websocket.remote_address)  # 无效状态self.clients.remove(websocket)breakexcept Exception as err:print("ws:", err)passdef connect(self):asyncio.set_event_loop(asyncio.new_event_loop())start_server = websockets.serve(self.echo, self.host, self.port)asyncio.get_event_loop().run_until_complete(start_server)asyncio.get_event_loop().run_forever()print("连接成功！")def run(self):t = threading.Thread(target=self.connect)t.start()print("已启动！")

二、主线程内启动子线程接收并处理数据

收到消息后根据情况处理消息

主线程调用服务端：main.py

from web_server import WebServerclass MainThread:def __init__(self):self.ws = WebServer("192.168.6.28", 8000)self.ws.run()def run(self):while True:try:data = self.ws.msg_queue.get()# flag = data.get("flag")  # 内容标签 判断是否是自己想要的内容# if not flag:#    continuetry:# 处理数据print(data)passexcept Exception as e:print("报错:", e)except Exception as err:print("报错:", err)passif __name__ == '__main__':M = MainThread()M.run()

客户端：web_client.py

客户端连接服务端，并发送消息

import jsonimport websocketclass WebClient:def __init__(self, host, port):self.host = hostself.port = portself.conn = Noneself.flag = Falsedef connect(self):try:url = f"ws://{self.host}:{self.port}"self.conn = websocket.create_connection(url)self.flag = Trueexcept Exception as err:self.flag = Falsedef close(self):self.conn.close()def recv(self):data = self.conn.recv(1024)print(data)def send(self, data):self.conn.send(data)if __name__ == '__main__':host = "192.168.6.28"# host = "127.0.0.1"port = 8000ws = WebClient(host, port)if not ws.flag:ws.connect()with open("bb.txt") as f:data = f.read()ws.send(data)
