Flask-SocketIO是一个基于Flask框架的WebSocket库,它提供了实时双向通信的能力。它可以用于构建实时聊天应用、实时数据展示和实时协作工具等。 CORS(跨域资源共享)是一种安全策略,用于限制跨域请求的访问权限。当浏览器发起跨域请求时,如果目标服务器没有正确配置CORS策略,浏览器会阻止该请求。 对于被CORS策略阻止的情况,...
实际上我在实例化SocketIO时已经传入cors_allowed_origins的参数为*,但是最后的问题出在*要用单引号,不能用双引号。我觉得这可能是前后传参符号不一致导致的,应该不是必须要求写单引号。 # 错误的写法 socketio = SocketIO(app, cors_allowed_origins="*", async_mode='eventlet') # 正确的写法 socketio = ...

在python中实现socket服务端的⽅式有⾮常多,⼀种最常⽤的有python-socketio,⽽我们现在使⽤的flask框架也有⼀个基于python-socket模块进⾏了封装的flask-socketio模块.注意:因为⽬前还有会存在⼀⼩部分的设备或者应⽤是不⽀持websocket的.所以为了保证功能的可⽤性,我们使⽤socktio模块,...
Do I need any additional settings for CORS support? Note: I'm running the socketio server under gunicorn with an eventlet worker (had to change to this since the gevent dependency has been dropped), and reverse-proxying via apache (2.4+ now has support for web sockets) Thanks! #5 Miguel...
