Nginx PHP-FPM 5.6 PATH_INFO 空的

我用 nginx 1.14.0 和 php-fpm5.6 在 Ubuntu 18.04. 当我看看我的变量 PHP 通过 info.php, 多变的 PATH_INFO 空的。 我想知道什么可能是错的？

/etc/nginx/sites-enabled/mysite.conf

location ~ [^/]\.php(/|$) {

        fastcgi_pass php56; # upstream server named in /conf.d/default.conf

        include fastcgi_params;

        fastcgi_keep_conn on;

        fastcgi_connect_timeout 30;

        fastcgi_send_timeout 600;

        fastcgi_read_timeout 600;

        fastcgi_buffers 256 16k;

        fastcgi_max_temp_file_size 0;

        fastcgi_index index.php;



        # regex to split $uri to $fastcgi_script_name and $fastcgi_path

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



        # Bypass the fact that try_files resets $fastcgi_path_info

        # see: [url=http://trac.nginx.org/nginx/ticket/321]http://trac.nginx.org/nginx/ticket/321[/url]

        set $path_info $fastcgi_path_info;







        # Check that the PHP script exists before passing it

        try_files $fastcgi_script_name =404;

}

/ 等等。 / nginx / fastcgi_params

fastcgi_param   QUERY_STRING        $query_string;



fastcgi_param   REQUEST_METHOD      $request_method;

fastcgi_param   REQUEST_URI     $request_uri;

fastcgi_param   REQUEST_SCHEME      $scheme;



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   DOCUMENT_URI        $document_uri;

fastcgi_param   DOCUMENT_ROOT       $document_root;



fastcgi_param   SERVER_PROTOCOL     $server_protocol;

fastcgi_param   SERVER_SOFTWARE     nginx/$nginx_version;

fastcgi_param   SERVER_ADDR     $server_addr;

fastcgi_param   SERVER_PORT     $server_port;

fastcgi_param   SERVER_NAME     $server_name;



fastcgi_param   HTTPS           $https if_not_empty;

fastcgi_param   GATEWAY_INTERFACE   CGI/1.1;



fastcgi_param   REMOTE_ADDR     $remote_addr;

fastcgi_param   REMOTE_PORT     $remote_port;



fastcgi_param   PATH_INFO       $path_info;



# PHP only, required if PHP was built with --enable-force-cgi-redirect

fastcgi_param   REDIRECT_STATUS     200;
