我有代码，我应该从API检索数据，并显示在wordpress的帖子。我已经面临的问题，以显示后的图像作为特色图像我不好与php，所以我认为我做了一些错误的代码

function my_function()
{
    $data = file_get_contents("http://datastorageuniversal.com/profiles_data");
    $response = json_decode($data, true);
    $item = $response['data'][0];

    $eyes = $item["eyes"];
    $hair = $item["hair"];
    $height = $item["height"];
    $weight = $item["weight"];

    $hair = $item["hair"];
    $Charges = $item["Charges"];
    $image_url = $item['image_url'];
    $name = "ASLYN SMITH";

        $bond = $charges['bond'];
        $image_path = WP_CONTENT_DIR . '/uploads/' . basename($image_url);

        // Check if post already exists for current data
        $existing_post_id = get_posts(array(

            // Post already exists, update post content
            $new_post_id = $existing_post_id[0];

                'post_category' => implode(',', array($category_id))

            wp_update_post($new_post);
            set_post_thumbnail($new_post_id, $attachment_id);

            $new_post_id = wp_insert_post($new_post);

            // Save data hash as custom field to check for duplicates
            update_post_meta($new_post_id, 'data_hash', md5(json_encode($item)));
        }
    }
}
add_action('init', 'my_function');

我试图在$post_conent上显示它们为img src=，但在这种情况下，我在控制台上得到404错误，
