set() if __name__ == '__main__': socketio.run(app) 上述代码使用Flask和socketio创建了一个简单的Web应用,其中包含一个后台线程background_thread,该线程每秒向客户端发送一个递增的计数值。当客户端连接时,会启动后台线程;当客户端断开连接时,会停止后台线程。
正确的解决方式是,在实例化SocketIO时,加上 cors_allowed_origins="*" socketio = SocketIO(app , cors_allowed_origins="*") 1. 主要代码如下: # coding=utf-8 import os import re from threading import Lock from flask import Flask, render_template from flask_socketio import SocketIO from config ...
