通过python-socketio发送数据，但无法接收flask socketio上的数据
提问于 2020-07-16 07:17:14
我正在尝试从我使用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的服务器上执行以下代码
#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)我可以接收sid，但在发送到WebSocket时无法获取在client.py中给出的参数
# Error Server.py

第一个问题是您正在使用connect事件，但此事件是保留的。将事件名称更改为其他名称：
@socket_app.on('connected')
def handle_id(data):
print(data)
print(request.sid)第二个问题是，在您的客户端调用wait()，它会一直阻塞到连接结束，因此您的emit()调用永远不会运行。在等待之前发送emit：
sio.connect('http://127.0.0.1:3000')
sio.emit('connected', {"Data": "Device_id"})
