Woocommerce - Retrieve shipping class

问题

I use following code on external script to retrieve all products (simple and variable):

    $args = array(
        'post_type'   => array('product', 'product_variation'),
        'numberposts' => -1,
        'post_status' => 'publish',
    );
    $shop_products = get_posts( $args );
    foreach ($shop_products as $item) {
        echo $item->ID.": shipping class is -> ".$item->get_shipping_class()."<br>";
    }

I need to create a list of product with their own shipping class, but it doesn't works. It shows me the error "Call to undefined method WP_Post::get_shipping_class()".

What is wrong? How can I fix it?

I have modified your code. Try following ---

$args = array(
        'post_type'   => array('product', 'product_variation'),
        'numberposts' => -1,
        'post_status' => 'publish',
    );
    $shop_products = get_posts( $args );
    foreach ($shop_products as $item) {
        $product = wc_get_product($item->ID);
        echo $item->ID.": shipping class is -> ".$product->get_shipping_class()."<br>";
    }
