插件中的get_post_meta返回错误值

Question

我想在插件中使用get_post_meta，但返回错误值 以下是我的代码：

    $wp_tags = array("{ID}","{title}","{music128}","{excerpt}","{content}","{author}","{short_url}","{full_url}","{tags}","{categories}");
    $wp_subs = array(
    $post->ID,
    $post->post_title,
    $post_meta = get_post_meta($post->ID, 'music128',true),
    wp_trim_words($post->post_content, $excerpt_length, "..."),
    $post->post_content,
    get_the_author_meta("display_name",$post->post_author),
    wp_get_shortlink($ID),
    get_permalink($ID),
    $tags,
    $categories
    );

get_post_meta结果是http：//*******.com/Music/shahrivar97/Ebrahim20%20-20Deylar.mp3找不到此链接错误404  但原始网址是http：//*******.com/Music/shahrivar97/Ebrahim%20Alizade%20%20-%20Sani%20Deylar.mp3
