您可以在主题函数中修改REST API响应。php就是这样。
function ws_register_images_field() {
register_rest_field(
\'post\',
\'images\',
array(
\'get_callback\' => \'ws_get_images_urls\',
\'update_callback\' => null,
\'schema\' => null,
)
);
}
add_action( \'rest_api_init\', \'ws_register_images_field\' );
function ws_get_images_urls( $object, $field_name, $request ) {
$medium = wp_get_attachment_image_src( get_post_thumbnail_id( $object->id ), \'medium\' );
$medium_url = $medium[\'0\'];
$large = wp_get_attachment_image_src( get_post_thumbnail_id( $object->id ), \'large\' );
$large_url = $large[\'0\'];
return array(
\'medium\' => $medium_url,
\'large\' => $large_url,
);
}

修改@ville6000示例，我能够解决自己的问题，
add_action( \'rest_api_init\', \'ws_register_images_field\' );
function ws_register_images_field() {
register_rest_field(
\'post\', //custom post name
\'attachment_url_images\', //array name of your choice
array(
\'get_callback\' => \'ws_get_images_urls\',
\'update_callback\' => null,
\'schema\' => null,
)
);
}
function ws_get_images_urls( $object, $field_name, $request ) {
$custom_fields = get_post_custom($object[\'id\']);
$main_image = $custom_fields[\'your_custom_images_array_name\'];
$image_urls = array();
foreach ( $main_image as $key => $value ) {
$imagesID = explode(\',\' ,$value);
foreach ($imagesID as $id => $value) {
$image_urls[ $key ] = wp_get_attachment_url($value);
//$custom_fields[ $id ] = $image_urls;
}
};
return $image_urls;
//return count($main_image);
}
结束
