How to force www on nginx and symfony

Question

I need to always replace domain.com with www.domain.com and to force https so the final result should always be https://www.domain.com when domain.com or www.domain.com are requested i tried the follows the website is still accessible with https but www is not being forced:

.htaccess

RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

nginx

server {
    listen 80;
    server_name domain.com;

    return 301 $scheme://www.domain.com$request_uri;
}

server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  www.domain.com;
        root         /path/to/project;
        location / {
                try_files $uri /app.php$is_args$args;
        }
        location ~ ^/(app_dev|config)\.php(/|$) {
                fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
                fastcgi_split_path_info ^(.+\.php)(/.*)$;
                include fastcgi_params;
                fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
                fastcgi_param DOCUMENT_ROOT $realpath_root;
        }
        location ~ ^/app\.php(/|$) {
                fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
                fastcgi_split_path_info ^(.+\.php)(/.*)$;
                include fastcgi_params;
                fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
                fastcgi_param DOCUMENT_ROOT $realpath_root;
                internal;
        }
        location ~ \.php$ {
                return 404;
        }
        location ~ /\. {
                deny all;
        }
        location ~ /.well-known {
                allow all;
        }
        error_log /path/to/error.log;
        access_log /path/to/access.log;
}
server {
        listen 443 ssl;

        server_name  www.domain.com;

        ..rest of code..
}

nginx another approach

server {
    listen      80;
    server_name domain.com;
    rewrite     ^   https://www.domain.com$request_uri? permanent;
}

and couple of another approaches found on search but it seems nothing is working for me i would appreciate any help. Thanks in advance.

Answer 1

HTTP to HTTPS:

server {
        listen 80;
        server_name *;
        location / {
                return 302 https://$host$request_uri;
        }
}

Non-WWW to WWW:

server {
        server_name domain-without-www.com;
        listen 443 ssl;
        location / {
                return 302 https://www.$host$request_uri;
        }
}

Make sure to replace the domains and having an extra server block with the server_name having www.domain.com.

Answer 2

i found the solution for reference posting :

for http

location / {
           if ($http_host !~ "^www\."){
                  rewrite ^(.*)$ http://www.$http_host$1 redirect;
           }
           try_files $uri /app.php$is_args$args;
}

for https

location / {
        if ($http_host !~ "^www\."){
                rewrite ^(.*)$ https://www.$http_host$1 redirect;
        }
        try_files $uri /app.php$is_args$args;
}
