我正在尝试从使用 python-socketio 的客户端发送数据，如下所述
#Client.py
import time
import socketio
sio = socketio.Client(engineio_logger=True)
start_timer = None
# if __name__ == '__main__':
sio.connect('http://127.0.0.1:3000')
sio.wait()
sio.emit('connect', {"Data": "Device_id"})
并尝试在使用flask-socketio的服务器上，如下面的代码中所述
#Server.py
from flask import Flask, render_template, request, jsonify
from flask_socketio import SocketIO
app = Flask(__name__)
# app.config['SECRET_KEY'] = "Social Distance Secret"
socket_app = SocketIO(app)
@socket_app.on('connect')
def handle_id(data):
print(data)
print(request.sid)
if __name__ == '__main__':
socket_app.run(app, debug=True, host='127.0.0.1', port=3000)
我能够接收 sid，但在发送到 WebSocket 时无法获取我在 client.py 中给出的参数
# Error Server.py

任何建议都会很有帮助
