Not sure what you're trying to do - publish topics to NodeBB from another software? Wonder if this will help you: https://github.com/psychobunny/nodebb-plugin-blog-comments Lets you post a new topic (or reply to topics) from Ghost. I want to do WP in the future as well

1、Can I get data format？ 2、websocket use port 80？ 3、Can I write a test example to send topic by websocket ?
