How to accept GET requests?

Question

PHP

There is a site (nginx + php). I'm trying to get a GET request to a controller. At first, there was a problem that when a link was made like site.ru/controller/action?login=test&pass=test, the Controller called the "action?login=test&pass=test" method, which naturally does not exist. wrote a rule for the router, which discards everything after the question. Great, now everything works, only in the action method itself, for some reason, I cannot accept GET.
The question is simple: how to get GET in this case? Or how is it done when using MVC?
UPD: Attached nginx config.

server {
    listen   80;
    root /var/www/site/public_html;

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

    server_name site.ru *.site.ru;

    location / {
        index index.php index.html index.htm;
        try_files $uri $uri/ /index.php;
    }

    location ~ \.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    location /phpmyadmin {
        root /usr/share/;
        index index.php index.html index.htm;
        location ~ ^/phpmyadmin/(.+\.php)$ {
            try_files $uri =404;
            root /usr/share/;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            include /etc/nginx/fastcgi_params;
        }
        location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
            root /usr/share/;
        }
    }

    location /phpMyAdmin {
        rewrite ^/* /phpmyadmin last;
    }
}

Thanks Aleksey POS_troi It was in nginx, it was worth doing this:

location / {
        index index.php index.html index.htm;
        try_files $uri $uri/ /index.php?$query_string;
    }

Should we beg you to show the nginx config or will you show it yourself? :)

Answer 3

The minimal configuration looks like this:
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
}
And don't forget to put cgi.fix_pathinfo = 0; in php.ini
