Answer 1

迁移网站后，我遇到了同样的问题，在wordpress中重新保存了设置->固定链接 ，将其修复。

Answer 2

FINALLY FIXED!!

Since I'm using nginx all the solutions doesn't worked for me.

I finally fixed that error adding the following lines to the nginx.conf (or file wich contains your server config)

location ~ ^/wp-json/ { rewrite ^/wp-json/(.*?)$ /?rest_route=/$1 last; }

I hope it helps to someone

Answer 3

You Error message clearly shows that particular endpoint doesn't exists.

http://example.com/wp-json/contact-form-7/v1/contact-forms/50/feedback

What i remember, the Wordpress json API mappings has base address of

http://example.com/wp-json/wp/v2/

So, try once if your url is working with this base address or not. Change url to

http://example.com/wp-json/wp/v2/contact-form-7/v1/contact-forms/50/feedback

Or just check proper mappings from http://example.com/wp-json .

This is not a Wordpress pre-defined endpoint and is enabled by Third party plugin mainly contact-form-7 . Make sure you have installed this plugin to your wordpress.

PS : Make sure you are using valid authentication method as certain end-points won't work without that.
