谢谢，但我从其他渠道得到了答案。我的答案是

$args = array(
//\'number\'=> $number,
//\'orderby\'=> $orderby,
//\'order\'=> $order,
\'hide_empty\'=> false,
//\'include\'=> $ids
);
    $product_categories = get_terms( \'product_cat\', $args );
    foreach($product_categories as $catval)
    {$catval->name;
    $link = esc_url( get_term_link( $catval, $catval->taxonomy ) );
    // get the thumbnail id user the term_id
    $thumbnail_id = get_woocommerce_term_meta( $catval->term_id, \'thumbnail_id\', true );
    // get the image URL
    $image = wp_get_attachment_url( $thumbnail_id );
