我正在尝试在两个 python 文件之间建立套接字连接以进行测试。我的服务器应该将一些数据上传到正在监听的客户端。我试图通过创建一些虚拟客户端来测试它。客户端连接后，我得到

websocket._exceptions.WebSocketBadStatusException: Handshake status 404 NOT FOUND

不幸的是，我在网上找不到针对此错误的任何解决方案

import time
from threading import Thread
from flask import Flask
from flask_socketio import SocketIO
from flask_sockets import Sockets
from websocket import create_connection

app = Flask(__name__)
socketio = SocketIO(app)
sockets = Sockets(app)


@sockets.route('/socket_test')
def update_time(ws):
    while not ws.closed:
        ws.send('hello world')
        time.sleep(1)


class Client(Thread):
    def __init__(self):
        super().__init__()

    def run(self):
        time.sleep(0.5)
        ws = create_connection('ws://localhost:5000/socket_test')
        while True:
            ws.recv()


if __name__ == '__main__':
    k = Client()
    k.start()
    socketio.run(app)

我希望客户端从服务器接收 hello world 消息
