所以我正在为 ctf 挑战编写 soem 代码，基本上我使用 socketio 与假的内部网络进行通信，但是当我使用 python3 bridge.pylocked_out.logicdata 运行以下代码时，我收到以下错误：Socketio错误：@sio.event AttributeError：“客户端”对象没有属性“事件”。有谁知道这可能是为什么？干杯!

#!/usr/bin/python3

'''
Use this script to connect to the Cars network and send your packets. 

A URL must be added bellow in order to connect.

You can either use it as a commandline tool and give the packet as an argument or
change the script to fit your needs
'''

import socketio
import time
import sys

# Insert here provided URL
URL = 'http://some_url_for_ctf_challenge' 

# Init socket
sio = socketio.Client()


@sio.event
def connect():
    print('[!] connection established')

@sio.event
def disconnect():
    print('disconnected from server')


print("[!] Connecting to server..")

# Connect to the network
sio.connect(URL) 

# Give the packet as an argument
packet = sys.argv[1]


# Do NOT remove - Use sleep to not flood the network
time.sleep(0.1) 

print("[!] Sending packet")

# Send data into the network
sio.emit('endpoint', packet)


# close connection
sio.disconnect()
