php `$_SERVER['PHP_SELF']` 为空

Question

我的 nginx 和 php 配置有问题。由于某种原因，$_SERVER['PHP_SELF'] 为空。

我在跑步：

• Ubuntu 18.04
• nginx（nginx版本：nginx/1.14.0（Ubuntu））
• php (PHP 7.2.10-0ubuntu0.18.04.1)

我不知道可能导致此问题的原因。我在网上看了很多，但找不到任何解决方案。

只是想看看是否缺少更多信息，我检查了我从 print_r($_SERVER); 得到的信息，这就是我得到的信息（已审查的私人信息...）：

数组 ( [USER] => www-data [HOME] => /var/www [HTTP_COOKIE] => 审查 [HTTP_ACCEPT_LANGUAGE] => en-GB,en;q=0.9, he-IL;q=0.8,he;q=0.7,en-US;q=0.6,ru;q=0.5 [HTTP_ACCEPT_ENCODING] => gzip, deflate, br [HTTP_ACCEPT] => text/html,application/xhtml+ xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8 [HTTP_USER_AGENT] => 审查 [HTTP_UPGRADE_INSECURE_REQUESTS] => 1 [ HTTP_CACHE_CONTROL] => max-age=0 [HTTP_CONNECTION] => keep-alive [HTTP_HOST] => cumta.morhaviv.com [SCRIPT_FILENAME] => /var/www/morhaviv.com/public_html/cumta/css/test.php [REDIRECT_STATUS] => 200 [SERVER_NAME] => www.cumta.morhaviv.com [SERVER_PORT] => 443 [SERVER_ADDR] => 153.92.209.235 [REMOTE_PORT] => 22964 [REMOTE_ADDR] => 176.231.2.86 [SERVER_SOFTWARE] = > nginx/1.14.0 [GATEWAY_INTERFACE] => CGI/1.1 [HTTPS] => on [REQUEST_SCHEME] => https [SERVER_PROTOCOL] => HTTP/1.1 [DOCUMENT_ROOT] => /var/www/morhaviv.com/public_html/ cumta [DOCUMENT_URI] => /css/test.php [REQUEST_URI] => /css/test.php [SCRIPT_NAME] => /css/test.php [CONTENT_LENGTH] => [CONTENT_TYPE] => [REQUEST_METHOD] => GET [QUERY_STRING] => [PATH_INFO] => [FCGI_ROLE] => RESPONDER [PHP_SELF] => [REQUEST_TIME_FLOAT ] => 1549710420.5126 [REQUEST_TIME] => 1549710420)

我的 nginx.conf：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {
    include        fastcgi_params; 
    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##
    # Gzip Settings
    ##

    gzip on;

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

我知道这个问题可能缺少一些需要的更多信息，但我真的不知道还有什么重要的，所以请发表评论，我会添加缺失的信息。

感谢您的帮助！

Answer 1

将 fix_pathinfo 设置为 1 是一个潜在的漏洞。而是将此行添加到 nginx php_fpm 部分：

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

只需手动分配全局变量：

$_SERVER['PHP_SELF'] = !empty($_SERVER['PHP_SELF']) ？ $_SERVER['PHP_SELF'] : '/'.basename($_SERVER['SCRIPT_FILENAME']);

Answer 2

一些用php安装nginx服务器的教程，坚持把php.ini文件的参数cgi.fix_pathinfo改成0。

所以我的解决方案在php.ini:

cgi.fix_pathinfo = 0 

到默认值：

cgi.fix_pathinfo = 1

基本上就是这样。

Answer 3

确保在 nginx 配置文件中包含这一行：

include fastcgi_params

除此之外，我认为它没有任何不工作的理由。
