在全栈开发中,前端和后端通常运行在不同的域上,因此可能会遇到跨域资源共享(CORS)问题。要解决这个问题,可以在后端框架中配置CORS策略。 使用Django解决CORS问题 在Django中,可以使用django-cors-headers库来轻松配置CORS策略。 pipinstalldjango-cors-headers
The Socket.IO Server This package contains two Socket.IO servers: The :func:`socketio.Server` class creates a server compatible with the Python standard library. The :func:`socketio.AsyncServer` class creates a server compatible with the asyncio package. The methods in the two serv...
