WordPress REST API和WP JSON API有什么不同？

Question

I'm trying to code the user authentication feature for my app using API. I'm confused between WordPress REST API and WordPress JSON API? Based on the Q&A here, it says I need WordPress JSON API. If my WP already has REST API, do I still need this JSON API?

Yes, they appear to be different. The Wordpress REST API appears to be built into, and come with a Wordpress Installation. I tested on my site, and was able to access the api for posts via a browser GET to /wp-json/wp/v2/posts. This is just an example. I would imagine the other option you mentioned is a plugin that does something similar but the format of the requests look entirely different. I would stick with the first solution that comes out of the box.
