正常wp-rest-api输出的内容是不包含自定义字段的,如果想输出自定义字段的内容,可以这样解决:

1、在wordpress根目录下找到wp-includes / rest-api.php文件,

2、在文件中添加以下代码:

/添加自定义字段输出/

add_action( ‘rest_api_init’, ‘create_api_posts_meta_field’ );

function create_api_posts_meta_field() {

// register_rest_field ( 'name-of-post-type', 'name-of-field-to-return', array-of-callbacks-and-schema() )
register_rest_field( 'post', 'post-meta-fields', array(
 'get_callback' => 'get_post_meta_for_api',
 'schema' => null,
 )
);

}

function get_post_meta_for_api( $object ) {
//get the id of the post object array
$post_id = $object[‘id’];

//return the post meta
	return get_post_meta( $post_id );

}

问题解决!!!
