Python server programming: Implementing WebSockets using django-channels

In today's web development, real-time communication is one of the indispensable features. Since the HTTP protocol is a request-response protocol, it is very inconvenient to use the traditional method of HTTP to achieve real-time communication. The WebSockets protocol is an emerging protocol that provides real-time two-way communication capabilities for Web applications and can send and receive data on the same connection, making it very suitable for real-time applications. In Python server programming, you can use the django-channels framework to easily
