php - 使用 error_page 检索 REDIRECT_STATUS

Question

使用.htaccessand ErrorDocument 404 /error.php，如果访问无效的 url，例如http://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error_page 404 /error.php;这个是行不通的，在 Nginx 中的结果是：

REDIRECT_STATUS: 200
REDIRECT_URL: 
REDIRECT_REQUEST_METHOD: 

注意：REDIRECT_URL 和 REDIRECT_REQUEST_METHOD 是未定义的

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

fastcgi_params 文件：

fastcgi_param   QUERY_STRING            $query_string;
fastcgi_param   REQUEST_METHOD          $request_method;
fastcgi_param   CONTENT_TYPE            $content_type;
fastcgi_param   CONTENT_LENGTH          $content_length;

fastcgi_param   SCRIPT_FILENAME         $document_root$fastcgi_script_name;
fastcgi_param   SCRIPT_NAME             $fastcgi_script_name;
fastcgi_param   PATH_INFO               $fastcgi_path_info;
fastcgi_param   PATH_TRANSLATED         $document_root$fastcgi_path_info;
fastcgi_param   REQUEST_URI             $request_uri;
fastcgi_param   DOCUMENT_URI            $document_uri;
fastcgi_param   DOCUMENT_ROOT           $document_root;
fastcgi_param   SERVER_PROTOCOL         $server_protocol;

fastcgi_param   GATEWAY_INTERFACE       CGI/1.1;
fastcgi_param   SERVER_SOFTWARE         nginx/$nginx_version;

fastcgi_param   REMOTE_ADDR             $remote_addr;
fastcgi_param   REMOTE_PORT             $remote_port;
fastcgi_param   SERVER_ADDR             $server_addr;
fastcgi_param   SERVER_PORT             $server_port;
fastcgi_param   SERVER_NAME             $server_name;

fastcgi_param   HTTPS                   $https;

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

要在 Nginx 中修复它，您需要创建一个假的location.

例子：

# Set fake location for 404
error_page 404 @fakeroute404;

# Access fake location
location @fakeroute404 {
    ...# Others needed settings

    include /etc/nginx/fastcgi_params; # Include fastcgi params

    fastcgi_param REDIRECT_REQUEST_METHOD "GET"; # Set HTTP method
    fastcgi_param REDIRECT_STATUS 404;  # Set HTTP status
    fastcgi_param REDIRECT_URL $uri;    # Set REDIRECT_URL
}
