– flask默认使用wsgi支持http协议，如需使用websocket需要安装gevent-websocket模块，http，websocket协议都可以支持

Django应用：channel

Tornado应用：自己有

　pip3 install gevent-websocket

app.py

from flask import Flask,request,render_template,redirect,session
import uuid
from geventwebsocket.handler import WebSocketHandler
from gevent.pywsgi import WSGIServer
import json


app = Flask(__name__)
app.secret_key = ';lkjnfdidiclsjek'
