How to get custom field values with WP Json API?

Hi,

I am using wordpress api and I am trying to retrieve custom field values from (for example) this page (localhosted):
https://127.0.0.1:8080/wp-json/wp/v2/pages/25

{"id":25,"date":"2017-01-11T10:28:05","date_gmt":"2017-01-11T09:28:05","guid":{"rendered":"http:\/\/127.0.0.1:8080\/wordpress\/?page_id=25"},"modified":"2017-01-11T10:51:21","modified_gmt":"2017-01-11T09:51:21","slug":"bloc1","type":"page","link":"http:\/\/127.0.0.1:8080\/wordpress\/menu\/bloc1\/","title":{"rendered":"bloc1"},"content":{"rendered":"<p>ezfezfez<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ezfezfez<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":23,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"_links":{"self":[{"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/pages\/25"}],"collection":[{"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/comments?post=25"}],"version-history":[{"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/pages\/25\/revisions"}],"up":[{"embeddable":true,"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/pages\/23"}],"wp:attachment":[{"href":"http:\/\/127.0.0.1:8080\/wordpress\/wp-json\/wp\/v2\/media?parent=25"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

This is what i got, and no custom field… :-(.

Any help?
