When calling WordPress REST API v2, the per_page parameter is totally ignored.
Expected behaviour for https://gao.bo/asahi/wp-json/wp/v2/posts?per_page=1 is to return only 1 post however it returns 10 posts, which is the default for pagination set by WordPress. Seems that it completely ignores the GET parameter given.
https://gao.bo/asahi is a subsite for https://gao.bo by the way.
The site is in Simplified Chinese but I don’t think that will affect the API behaviour right?
WordPress version: 6.5.3
