$ _SERVER [＆＃39; HTTP_X_REQUESTED_WITH＃39;]在nginx php5-fpm服务器上始终为空

Question

我在Debian上安装了一个带有nginx和php5-fpm的新网络服务器。 但不知何故，即使请求来自jquery或javascript，$ _SERVER [＆＃39; HTTP_X_REQUESTED_WITH＆＃39;]也保持为空。我尝试了所有不同的选项，但它一直是空的。

这是我的fastcgi_param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  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  SERVER_NAME        $server_name;
fastcgi_param  HTTP_X_REQUESTED_WITH   $http_x_requested_with;

这是我的nginx.conf

这是我的网站文件

        if ($request_method = POST) {
                set $skip_cache 1;
        }
        if ($query_string != "") {

        location / {

                try_files $uri $uri/ /index.php$is_args$args;
        }



        # pass the PHP scripts to FastCGI server listening on /var/run/php5-fpm.sock
        location ~ \.php$ {

                fastcgi_pass unix:/var/run/php5-fpm.sock;

        }

        error_page 404 /index.php;

        # Deny .htaccess file access
        location ~ /\.ht {
                deny all;
        }
}

我希望有人可以帮我解决这个问题。我需要抓住jquery帖子，因为他们需要绕过登录页面。
