使用error_page检索REDIRECT_STATUS

使用 和 ，如果访问无效的网址，例如： ：.htaccessErrorDocument 404 /error.phphttp://example/css/invalid-file.css

<?php
echo 'REDIRECT_STATUS: ', $_SERVER['REDIRECT_STATUS'], PHP_EOL,
     'REDIRECT_URL: ', $_SERVER['REDIRECT_URL'], PHP_EOL,
     'REDIRECT_REQUEST_METHOD: ', $_SERVER['REDIRECT_REQUEST_METHOD'];

输出：

REDIRECT_STATUS: 404
REDIRECT_URL: /css/invalid-file.css
REDIRECT_REQUEST_METHOD: GET

但是在Nginx中使用这个是行不通的，Nginx的结果是：error_page 404 /error.php;

REDIRECT_STATUS: 200
REDIRECT_URL: 
REDIRECT_REQUEST_METHOD: 

注意：REDIRECT_URL和REDIRECT_REQUEST_METHOD未定义

如何设置变量，并使用Ngnix？$_SERVER[REDIRECT_STATUS]$_SERVER[REDIRECT_REQUEST_METHOD]$_SERVER[REDIRECT_URL]
