Nginx + PHP-FPM 執行腳本，但返回 404

我正在使用 Nginx + PHP-FPM 執行基於 Wordpress 的站點。我有一個 URL，它應該返回動態生成的 JSON 數據，以便與 DataTables jQuery 外掛一起使用。數據正確返回，但返回碼為 404。我認為這是 Nginx 配置問題，但我無法弄清楚原因。腳本“getTable.php”在目前使用 Apache 的網站的生產版本上正常工作。任何人都知道我怎樣才能讓它在 Nginx 上工作？

網址：http ://dev.iloveskydiving.org/wp-content/plugins/ils-workflow/lib/getTable.php

伺服器：CentOS 6 + Varnish（為開發禁用記憶體）+ Nginx + PHP-FPM + Wordpress + W3 總記憶體

Nginx 配置：

   server {

   # Server Parameters
   listen       127.0.0.1:8082;

       fastcgi_split_path_info ^(.+\.php)(/.+)$;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

更新： 經過進一步探勘，看起來 Nginx 正在生成 404，而 PHP-FPM 正在正確執行腳本並返回 200。

更新： 以下是腳本的內容：

   <?php
/**
* Connect to Wordpres
*/
require(dirname(__FILE__) . '/../../../../wp-blog-header.php');

/**
* Define temporary array
*/
$aaData = array();
$aaData['aaData'] = array();

/**
* Execute Query
*/
$query = new WP_Query(
   array(
       'post_type'      => 'post',
       'posts_per_page' => '-1'
   )
);

foreach ($query->posts as $post) {

   array_push(
       $aaData['aaData'],
       array(
           $post->post_title
       )
   );

}

/**
* Echo JSON encoded array
*/
echo json_encode($aaData);

Panagiotis Papadomitsos 的問題促使我測試了幾個新的可能原因。我找到了以下文章： https ://cooltrainer.org/2010/06/20/fixing-false-404-headers-on-external-pages-include-wp-blog-header-php/

我在我的程式碼中更改了以下行：

regquire(dirname(__FILE__) . '/../../../../wp-blog-header.php');

到：

require(dirname(__FILE__) . '/../../../../wp-config.php');
$wp->init();
$wp->parse_request();
$wp->query_posts();
$wp->register_globals();
//$wp->send_headers();

似乎根本原因是 Wordpress 返回 404，而不是 Nginx，而不是 PHP-FPM。
