这是我打印出来的。

$args = array(
'category' => 'Animation',
'numberposts' => 8
);
$posts_array = get_posts( $args );
echo json_encode($posts_array);

结果如下：（有 8 个相同的 JSON 列表，为方便起见，仅显示 1 个。）

{"ID":554,"post_author":"1","post_date":"2012-12-28 19:17:43","post_date_gmt":"2012-12-28 19:17:43 ","post_content":"太空竞赛已经开始。随着各国的竞争，我们关注被招募到太空计划中的一只黑猩猩的进步。他的结果可能会为全人类带来更好的影响。......将他准备好迎接挑战了","post_title":"Alpha","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password" :"","post_name":"alpha","to_ping":"","pinged":"","post_modified":"2012-12-28 19:17:43","post_modified_gmt":"2012- 12-28 19:17:43","post_content_filtered":"","post_parent":0,"guid":"http://localhost/Wordpress%203.4.2/?p=554","menu_order": 0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"

但我只想发送 id 和 post_content。我不断得到空值，但不知道为什么。

【解决方案1】：

只需按您需要的字段进行过滤：（id and the post_content 或 title and permalink）

$args = array(
    'category'       => 'Animation',
    'numberposts'    => 8
);

$posts_array = get_posts($args);

$send_array = array();
foreach ($posts_array as $key => $value)
{
    $send_array[$key]["ID"]          = $value->ID;
    $send_array[$key]["post_content"]    = $value->post_content;
}

echo json_encode($send_array);
exit;
