I would like to send a message through WeChat public account, the computer screen directly through the barrage display?

What technologies are needed for this period? Or how to make it happen, can you tell me about the process. Thank you.

Storage + Polling
The store can use Message Queuing (RabbitMQ), the callback method as the producer (Producer), to place messages to the message queue;
Polling can write a single method as a consumer (Consumer), read messages from Message Queuing, and perform business processing.

I don't quite understand what you mean, can you describe it clearly, so let me help you?

Message is saved to the database with an interface
The computer loops through the database, and there's a new message.

See your performance requirements, if the general can poll on the line, if you want to higher real-time and stability can use the channel service provided by SAE.
