WP API - 如何获取草稿帖子

Question

I am trying to get draft/preview/trash posts using the wordpress JSON API but adding the filter doesn't seem to do anything at all.

As a test, I am trying to get posts in the trash (there are non) but all published posts are returned.

http://localhost/wp-json/posts?&filter[post_status]=trash

I have tried this whilst logged in and out of the admin panel, giving the same results.

I am assuming this was the way to do it based on the wordpress docs http://codex.wordpress.org/Class_Reference/WP_Query#Status_Parameters

I have attempted multiple params other than trash, all return only published posts.

EDIT:

I figured out that you cannot be logged into the admin panel for basic auth to work, otherwise it just gets overridden. Logging out of this and it all worked.

Answer 1

You have to be authenticated as a user with edit_posts permissions to access private query variables such as post_status. At which point you will be able to use the following (drop the &).

http://localhost/wp-json/posts?filter[post_status]=trash

EDIT:

I believe there is a way to add post_status manually, I haven't tested this but it should work.

function my_allowed_post_status( $valid_vars ) {

    $valid_vars = array_merge( $valid_vars, array( 'post_status' ) );
    return $valid_vars;
}
add_filter( 'rest_query_vars', 'my_allowed_post_status' );
