This article mainly introduces "order real-time message notification implementation". In daily operation, I believe many people have doubts about the implementation of order real-time message notification. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts of "order real-time message notification implementation"! Next, please follow the editor to study!

Some time ago, there was a need for real-time push of messages in our project. For example, when a user places an order in our software, merchants will receive the message that the customer has placed an order on our software without manually refreshing the page. That is, our backend actively pushes the message to the front end. We considered the use of real-time communication technology. Now our project is written in the django framework, we need to use Django-Channels to achieve communication, the communication protocol can not use http, because http does not support long connections, we use the websocket protocol in this project. About the use of django-channels can refer to its official document https://channels.readthedocs.io/en/latest/tutorial/index.html we have written another message synchronization service project, using the plug-in is django-channels. This project exposes an interface to send messages, which can be called by our mall background to send messages. The logic function of real-time push is that the front end connects to our message synchronization service (which can be understood as entering the game hall), and then subscribes to the url address we specify (it can be understood as entering a game room). Our software calls the API where the synchronization service sends messages to send messages to the specified subscription url address, so that we can actively push messages to the front end.

I handwritten a simple example of a chat room myself.

Use a browser to open two identical tabs, enter chat content on one tab, and receive messages on the other.

You can also send messages to the chat room through the interface.

At this point, the study on "order real-time message notification implementation" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
