Ajax GET parameters not populated on Nginx -

i on laravel project works locally (get, post requests on forms ajax). hard part when deploy on nginx, works except ajax calls. don't have parameters passed controllers. have like

$.ajax({    type: 'get',    url: '{{route('    test.route ') }}',    data: {      valuepassed: 5    },    success: function(data) {      alert(data);    }  })

with controller returning value passed return input::get('valuepassed') or return $request->valuepassed. value when running locally when on nginx param empty. here config :

server {     listen 80;     listen [::]:80;     root /var/www/html/mydomain/public;      index index.php index.html index.htm index.nginx-debian.html;      server_name mydomain.com www.mydomain.com;      location / {             try_files $uri $uri/ /index.php?query_string;     }     location ~ \.php$ {             include snippets/fastcgi-php.conf;             fastcgi_pass unix:/run/php/php7.1-fpm.sock;     } 

ps: i'm kinda new nginx

you seems have typo in config. below

try_files $uri $uri/ /index.php?query_string; 

should be

try_files $uri $uri/ /index.php?$query_string; 

you passing fixed param instead of 1 client. changing query_string $query_string should fix it
