Basic usage of WordPress REST API

The following columnWordPress Tutorialwill introduce you to the basic use of WordPress REST API. I hope it will be helpful to friends in need!

The WordPress system opensREST APIby default, that is to say, in addition to outputting content in HTML format,

can also output content in JSON format Output article/user/comments and other data.

The reason why JSON data format response is supported is because currently various smart terminal devices, such as mobile phones/tablets/TVs/routers/home appliances/toys, etc.,

have to communicate with the cloud server. Communication, and the data required by the terminal device does not necessarily have to be presented to the user after parsing HTML by the browser.

So JSON, a data format specification that is easy to write/read/parse, is usually used for data communication.

If you have deployed WordPress, you can get data in JSON format through the corresponding link:

Link format example:

Article list /wp- json/wp/v2/posts

Page list /wp-json/wp/v2/pages

User list /wp-json/wp/v2/ users

Replace the example domain name with your own domain name. If the page returns a 404 error, you need to set the redirection rules of the WEB proxy server (Nginx).
