推荐答案

woo-commerce 有自己的预定义功能，当时我不知道.使用 wc_add_notice 和 wc_clear_notices 解决了这个问题！

woo-commerce has their own predefined functions for this which i didn't know at that time.used wc_add_notice and wc_clear_notices solved the issue!

if(!empty($xml->ratedTransitTimeResponse->ratedProducts->ratedProduct[0]->quote->price)){

     $cost+=(float)$xml->ratedTransitTimeResponse->ratedProducts->ratedProduct[0]->quote->price;
     wc_clear_notices();
}                       
else
{   //wc_add_wp_error_notices(new WP_Error(1,'Shipping cost error'));
     wc_clear_notices();
     wc_add_notice( 'Shipping cost error', 'error' );
}
